RESUMO
Introduction: Chronic obstructive pulmonary disease (COPD) is a major cause of chronic morbidity and mortality worldwide. The natural course of COPD is characterized by acute exacerbation. Infectious agents, particularly bacteria, cause exacerbation of COPD in the majority. This study aimed to determine the bacteriology and antibiotic resistance patterns among patients with acute exacerbations of COPD (AECOPD) at Jimma Medical Center. Methods: A cross-sectional study was conducted from March to October 2019. Demographic, clinical, and sputa samples were collected from 39 study participants, who were diagnosed with AECOPD. Bacterial pathogens were identified using standard bacteriological techniques, and anti-microbial susceptibility testing was done by Kirby Bauer's disk diffusion method. Extended-spectrum ß-lactamase (ESßL) and carbapenemase production were confirmed by MASTTM D68C and MASTTM D73C combination disc sets, respectively. Chi-square and odds ratios were calculated. Results: Overall, 69.2% (27/39) of sputum samples were confirmed to be culture-positive. A total of 32 bacterial isolates with 78.1% (25/32) Gram-negative and 21.9% (7/32) Gram-positive bacteria were identified. The predominant bacterial isolates were Pseudomonas aeruginosa 21.9% (7/32), Klebsiella pneumoniae 18.75% (6/32), and Staphylococcus aureus 15.62% (7/32). Overall, 30 (93.8%) of the isolates were multidrug-resistant (MDR). About 48% (12/25) and 8 (32%)of gram negative bacterial isolates were ESBL betalatemase and OXA-48 carbapenemase producers, respectively. Having two or more exacerbation experiences in the previous year were found to be important determinants of the sputum culture positivity. Conclusions: High rates of MDR, ESBL, and carbapenemase producer bacteria were isolated from patients with AECOPD. Empiric antibiotic therapy should consider the prevalence of antibiotic-resistant pathogens and the factor that may increase the occurrence of MDR bacterial pathogens.
RESUMO
BACKGROUND: With nearly 15 million annual preterm births globally, preterm birth is the most common cause of neonatal death. Forty to 60 % of neonatal deaths are directly or indirectly associated with preterm mortality. As countries aim to meet the Sustainable Development Goals to reduce neonatal mortality, significant reductions in preterm mortality are needed. This study aims to identify the common causes of preterm illness and their contribution to preterm mortality in low-resource settings. This article will describe the methods used to undertake the study. METHODS: This is a prospective, multi-centre, descriptive clinical study. Socio-demographic, obstetric, and maternal factors, and clinical and laboratory findings will be documented. The major causes of preterm mortality will be identified using clinical, laboratory, imaging, and autopsy methods and use the national Ethiopian guidelines on management of preterm infants including required investigations to reach final diagnoses. The study will document the clinical and management protocols followed in these settings. The approach consists of clinical examinations and monitoring, laboratory investigations, and determination of primary and contributory causes of mortality through both clinical means and by post-mortem examinations. An independent panel of experts will validate the primary and contributory causes of mortality. To obtain the estimated sample size of 5000 preterm births, the study will be undertaken in five hospitals in three regions of Ethiopia, which are geographically distributed across the country. All preterm infants who are either born or transferred to these hospitals will be eligible for the study. Three methods (last menstrual period, physical examination using the New Ballard Score, and ultrasound) will be used to determine gestational age. All clinical procedures will be conducted per hospital protocol and informed consent will be taken from parents or caretakers prior to their participation in the study as well as for autopsy if the infant dies. DISCUSSION: This study will determine the major causes of death and illness among hospitalized preterm infants in a low-resource setting. The result will inform policy makers and implementers of areas that can be prioritized in order to contribute to a significant reduction in neonatal mortality.

The hospital environment is increasingly becoming an important reservoir for multi-drug-resistant (MDR) Gram-negative bacteria, posing serious challenges to efforts to combat antimicrobial resistance (AMR). This study aimed to investigate the role of hospital waste as a potential source of MDR ESBL-producing bacteria. Samples were collected from multiple sources within a hospital and its vicinity, including surface swabs, houseflies, and sewage samples. The samples were subsequently processed in a microbiology laboratory to identify potential pathogenic bacteria and confirmed using MALDI-TOF MS. Bacteria were isolated from 87% of samples, with the predominant isolates being E. coli (30.5%), Klebsiella spp. (12.4%), Providencia spp. (12.4%), and Proteus spp. (11.9%). According to the double disc synergy test (DDST) analysis, nearly half (49.2%) of the bacteria were identified as ESBL producers. However, despite exhibiting complete resistance to beta-lactam antibiotics, 11.8% of them did not test positive for ESBL production. The characterization of E. coli revealed that 30.6% and 5.6% of them carried blaCTX-M group 1 type-15 and blaNDM genes, respectively. This finding emphasizes the importance of proper hospital sanitation and waste management practices to mitigate the spread of AMR within the healthcare setting and safeguard the health of both patients and the wider community.
RESUMO
Background: In resource-constrained settings, limited antibiotic options make treating carbapenem-resistant bacterial infections difficult for healthcare providers. This study aimed to assess carbapenemase expression in Gram-negative bacteria isolated from clinical samples in Jimma, Ethiopia. Methods: A cross-sectional study was conducted to assess carbapenemase expression in Gram-negative bacteria isolated from patients attending Jimma Medical Center. Totally, 846 Gram-negative bacteria were isolated and identified using matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS). Phenotypic antibiotic resistance patterns were determined using the Kirby-Bauer disk diffusion method and Etest strips. Extended-spectrum ß-lactamase phenotype was determined using MAST disks, and carbapenemases were characterized using multiplex polymerase chain reactions (PCR). Results: Among the isolates, 19% (157/846) showed phenotypic resistance to carbapenem antibiotics. PCR analysis revealed that at least one carbapenemase gene was detected in 69% (107/155) of these strains. The most frequently detected acquired genes were blaNDM in 35% (37/107), blaVIM in 24% (26/107), and blaKPC42 in 13% (14/107) of the isolates. Coexistence of two or more acquired genes was observed in 31% (33/107) of the isolates. The most common coexisting acquired genes were blaNDM + blaOXA-23, detected in 24% (8/33) of these isolates. No carbapenemase-encoding genes could be detected in 31% (48/155) of carbapenem-resistant isolates, with P. aeruginosa accounting for 85% (41/48) thereof. Conclusion: This study revealed high and incremental rates of carbapenem-resistant bacteria in clinical samples with various carbapenemase-encoding genes. This imposes a severe challenge to effective patient care in the context of already limited treatment options against Gram-negative bacterial infections in resource-constrained settings.
RESUMO
BACKGROUND: The burden of multidrug-resistant bacterial infections in low-income countries is alarming. This study aimed to identify the bacterial etiologies and antibiotic resistance patterns among neonates in Jimma, Ethiopia. METHODS: An observational longitudinal study was conducted among 238 presumptive neonatal sepsis cases tested with blood and/or cerebrospinal fluid culture. The bacterial etiologies were confirmed using matrix-assisted laser desorption ionization-time of flight mass spectrometry. The antibiotic resistance patterns were determined using the automated disc diffusion method (Bio-Rad) and the results were interpreted based on the European Committee on Antimicrobial Susceptibility Testing 2021 breakpoints. Extended-spectrum ß-lactamases were detected using a double disc synergy test and confirmed by Mast discs (Mast Diagnostica GmbH). RESULTS: A total of 152 pathogens were identified. Of these, Staphylococcus aureus (18.4%) was the predominant isolate followed by Klebsiella pneumoniae (15.1%) and Escherichia coli (10.5%). All the isolates exhibited a high rate of resistance to first- and second-line antibiotics ranging from 73.3% for gentamicin to 93.3% for ampicillin. Furthermore, 74.4% of the Gram-negative isolates were extended-spectrum ß-lactamase producers and 57.1% of S. aureus strains were methicillin resistant. The case fatality rate was 10.1% and 66.7% of the deaths were attributable to infections by multidrug-resistant pathogens. CONCLUSIONS: The study revealed a high rate of infections with multidrug-resistant pathogens. This poses a significant challenge to the current global and national target to reduce neonatal mortality rates. To address these challenges, it is important to employ robust infection prevention practices and continuous antibiotic resistance testing to allow targeted therapy.

Under-reporting of COVID-19 and the limited information about circulating SARS-CoV-2 variants remain major challenges for many African countries. We analyzed SARS-CoV-2 infection dynamics in Addis Ababa and Jimma, Ethiopia, focusing on reinfection, immunity, and vaccination effects. We conducted an antibody serology study spanning August 2020 to July 2022 with five rounds of data collection across a population of 4723, sequenced PCR-test positive samples, used available test positivity rates, and constructed two mathematical models integrating this data. A multivariant model explores variant dynamics identifying wildtype, alpha, delta, and omicron BA.4/5 as key variants in the study population, and cross-immunity between variants, revealing risk reductions between 24% and 69%. An antibody-level model predicts slow decay leading to sustained high antibody levels. Retrospectively, increased early vaccination might have substantially reduced infections during the delta and omicron waves in the considered group of individuals, though further vaccination now seems less impactful.

Background and Objectives: Antibiotic resistance is a significant problem that restricts the options for treating bacterial pneumonia. This research aimed to determine the bacterial causes of pneumonia and antibiotic resistance among hospitalized patients in southwest Ethiopia. Materials and Methods: We collected and analyzed 150 sputum samples from individuals with community-acquired pneumonia from April 1st to October 30th, 2019. Standard bacteriological procedures were used to identify the bacteria. Kirby Bauer's disk diffusion method was used to assess the bacteria's susceptibility patterns. Production of carbapenemase and extended-spectrum-lactamase were confirmed phenotypically. Odds ratios and the chi-square test were computed. Results: On the whole, bacterial pathogens were verified in 50% of the sputum samples. The predominant bacterial isolates were Klebsiella species, followed by Pseudomonas aeruginosa, Staphylococcus aureus and Streptococcus pneumoniae. About 77.5% of isolates were multidrug resistant. Moreover, 40.5% and 10.8% of the isolates were ESBL and carbapenemase producers, respectively. Aging, tobacco smoking, previous history of pneumonia, heart disease, and chronic respiratory disease had association with sputum culture-positivity. Conclusion: As a result, it is important to regularly monitor the bacterial etiologies and their patterns of resistance. Additionally, sociodemographic and clinical characteristics should all be taken into account while managing patients with pneumonia empirically in this context.
RESUMO
Data is an essential tool for valid and reliable healthcare management. Access to high-quality data is critical to ensuring the early identification of problems, the design of appropriate interventions, and the effective implementation and evaluation of health intervention outcomes. During the COVID-19 pandemic, the need for strong information systems and the value of producing high-quality data for timely response and tracking resources and progress have been very evident across countries. The availability of and access to high-quality data at all levels of the health systems of low and middle-income countries is a challenge, which is exacerbated by multiple parallels and poorly integrated data sources, a lack of data-sharing standards and policy frameworks, their weak enforcement, and inadequate skills among those handling data. Completeness, accuracy, integrity, validity, and timeliness are challenges to data availability and use. "Big Data" is a necessity and a challenge in the current complexities of health systems. In transitioning to digital systems with proper data standards and policy frameworks for privacy protection, data literacy, ownership, and data use at all levels of the health system, skill enhancement of the staff is critical. Adequate funding for strengthening routine information systems and periodic surveys and research, and reciprocal partnerships between high-income countries and low- and middle-income countries in data generation and use, should be prioritized by the low- and middle-income countries to foster evidence-based healthcare practices.
RESUMO
BACKGROUND: Ethiopia is one of the high burden countries for extrapulmonary tuberculosis (EPTB); however, the prompt diagnosis of EPTB remains challenging. This study is aimed to evaluate the diagnostic performance of Xpert MTB/RIF and DetermineTM TB-LAM Ag (TB-LAM) for the prompt diagnosis of EPTB in Ethiopia. METHODS: A total of 147 presumptive EPTB patients, including 23 HIV- positive participants were enrolled. Extra-pulmonary samples were collected from all presumptive EPTB cases and tested for Mycobacterium tuberculosis complex (MTBC) using fluorescent microscopy, Xpert MTB/RIF, and culture. Additionally, urine samples were also collected from 126 participants and were tested by DetermineTM TB-LAM Ag (Alere Inc, Waltham, USA). The Sensitivity and specificity of Xpert and TB- LAM tests were calculated by comparing with a composite reference standard (CRS), which comprises smear microscopy, culture and response to empirical anti-TB treatment. RESULTS: Of 147 patients, 23 (15.6%) were confirmed EPTB cases (culture-positive), 14 (9.5%) were probable EPTB (clinically, radiologically or cytologically positive and received anti-TB treatment with good response), and 110 (74.8%) were classified as "non- TB" cases. Compared to the composite reference standard (CRS), the overall sensitivity and specificity of Xpert MTB/RIF were 43.2% and 100%, respectively with the highest sensitivity for Lymph node aspirate (85.7%) and lower sensitivity for pleural fluid (14.3%) and 100% specificity for all specimen types. The sensitivity and specificity of TB-LAM were 33.3% and 94.4% respectively with the highest sensitivity for HIV co-infected participants (83.3%). The sensitivity of the combination of Xpert MTB/RIF and TB-LAM tests regardless of HIV status was 61.1% whereas the sensitivity was improved to 83.3% for HIV-positive cases. CONCLUSION: TB-LAM alone has low sensitivity for EPTB diagnosis; however, the combination of TB-LAM and Xpert MTB/RIF improves the diagnosis of EPTB particularly for countries with high EPTB and HIV cases.

Background: In resource-constrained countries, accurate diagnosis of Helicobacter pylori infection remains a challenge. This study aimed to assess the clinical utility of locally available serological and stool antigen test kits in the management of people with suspected H. pylori infection in Ethiopia. Methods: A community-based cross-sectional study was conducted with apparently healthy adults and children living in southwest Ethiopia. Participants were interviewed for dyspepsia symptoms and related clinical conditions. H. pylori infection was examined using commercially available serological and stool antigen tests. The association between H. pylori tests and dyspepsia symptoms was analyzed using logistic regression models. Results: Out of 1392 participants included in the final analysis, 49.1% and 6.5% tested positive for H. pylori infection with serology and stool antigen test kits, respectively. Participants reporting epigastric symptoms in the past three months (AOR = 1.93, 95% CI = 1.28-2.91) and those with recent dyspepsia treatment (AOR = 1.51, 95% CI = 1.05-2.18) were likely to have positive serology test. However, no association between dyspepsia symptoms and H. pylori stool antigen positivity was observed in our study. Conclusion: ccurate detection of H. pylori infections using commercially accessible diagnostics remains difficult in Ethiopia. With these methods, it will be hard to ensure adequate diagnosis and early treatment of H. pylori infection, as well as rational antibiotic use.

BACKGROUND: Depression is the most common mental health problem, and frequently associated with physical illnesses. A link between depression, dyspepsia and Helicobacter pylori (H. pylori) infection has previously been reported. However, there is limited data regarding the association between these conditions from sub-Saharan Africa where they are highly prevalent. OBJECTIVE: This study aimed at elucidating the potential associations between depression, dyspepsia and H. pylori infection in Ethiopia. METHODS: We conducted a community based cross-sectional study involving urban and rural residents aged 13 years or older in Jimma Zone, southwest Ethiopia. A total of 871 participants were evaluated using a structured case reporting format for symptoms of dyspepsia and the patient health questionnaire (PHQ-9) for depression. Additionally, participants were assessed for H. pylori infection using stool antigen and serology tests. A multivariate logistic regression was used to identify the association between depression, dyspepsia and H. pylori infection after controlling for potential confounders. RESULTS: The prevalence of PHQ-9 scores indicative of probable case of depression among all participants was 10.9%. The prevalence of probable case of depression among patients who had at least one symptom of dyspepsia was 13.3% (X2 = 15.1 = p-value<0.001), while it was 11.9% (X2 = 1.23, p-value = 0.26) among patients who had H. pylori infection. Out of patients who took medications for their heartburn in the past 30 days, 14.9% (X2 = 3.6, p-value = 0.06) had probable case of depression. Dyspepsia symptoms such as epigastric discomfort (aOR = 2.59, 95%CI = 1.14, 5.87), postprandial fullness (aOR = 1.70, 95%CI = 1.48, 5.51), nausea (aOR = 1.71, 95%CI = 1.04, 2.82) excessive belching (aOR = 0.53, 95%CI = 0.31, 0.92) were associated with probable case of depression. However, being H. pylori test positive, gender, and age were not associated with probable case of depression. CONCLUSIONS: There was an increased prevalence of probable case of depression among patients who had dyspepsia symptoms and H. pylori infection. Longitudinal studies are needed to examine possible further determinants of association between symptoms of dyspepsia and probable case of depression.

INTRODUCTION: In the twenty-first century, antibiotic resistance is becoming one of the major global public health threats. Several complex factors are associated with the emergence and spread of antibiotic resistance. Emerging evidences are indicating that drugs used for chronic illness conditions might have a contribution for antibiotic resistance either through drug-drug interactions or metabolism of the drugs by gut microbiota. OBJECTIVE: The aim of this study was to compare the bacteria profile and resistance patterns of gut bacteria isolated from participants using psychotropic drugs and apparently healthy controls. METHODS: Socio-demographic data were collected from patients using psychotropic medications and apparently healthy persons. Clinical data were collected from patient records. Stool samples were collected from 107 patients using psychotropic medications and 107 apparently healthy controls. Gut bacterial flora were isolated and identified using oxidase, indole, and BD BBL crystal Enteric/Non-fermenter identification system. Antibiotic susceptibility test was done using the disk diffusion method, and Mast disks were used to identify extended-spectrum betalactamase (ESBL) and/or AmpC-producing isolates. RESULTS: A total of 245 bacterial isolates were isolated and identified. From these, 124 (50.6%) bacteria were isolated from patients using Psychotropic medications. There was no bacteria profile difference between the two groups. Escherichia coli was the prevalent [100 (80.6%) and 102 (84.3%)] bacteria isolated from patients using psychotropic medications and apparently healthy controls, respectively. Escherichia coli isolated from patients using psychotropic medications showed significantly higher resistance against amoxicillin-clavulanic acid, cephalosporin (2nd, 3rd, 4th generations), meropenem, ciprofloxacin and tetracycline. The odds of isolating ESBL-producing Enterobacteriaceae [(OR=2.3, 95% C.I: (1.4-4.0)] and MDR [OR=5.4, 95% C.I: (1.5-29.8)] were higher on patients using psychotropic medications. CONCLUSION: The observed antibiotic resistance pattern of bacteria isolated from guts of patients using psychotropic medications was very high. The magnitude of antibiotic resistance is more pronounced among E. coli isolates.
RESUMO
INTRODUCTION: Inappropriate antibiotic use is a major public health concern and driver of antibiotic resistance. Excessive exposure to antibiotics results in the emergence and spread of drug-resistant microorganisms. This study aimed to measure the volume of antibiotic consumption at the outpatient settings in a tertiary-care teaching hospital in Ethiopia. METHODS: A cross-sectional study was undertaken from February 01, 2019 to March 31, 2019 at Jimma Medical Center in southwest Ethiopia. Antibiotics use was analyzed using Anatomical Therapeutic Chemical Classification and Defined Daily Dose (DDD) system. Antibiotic use was calculated as DDD per 100 outpatients per day. Antibiotics were classified based on World Health Organization "AWaRe" classification scheme as "Access", "Watch" and "Reserve" group antibiotics and measured their consumption intensity. RESULTS: A total of 496 adult patients were included in the study. The mean (SD) age of participants was 33.07 (14.05) years. The total amount of antibiotics consumed was 5.31 DDD/100 outpatients per day. Ciprofloxacin was the most commonly [122 (21.12%)] prescribed antibiotics with DDD/100 outpatients per day value of 1.13, followed by amoxicillin [68 (11.76%)] with DDD/100 outpatients per day value of 0.44, and azithromycin [61 (10.55%)] with DDD/100 outpatients per day value of 0.51. On antibiotic consumption index, antibiotics in the "Watch" group had 2.10 DDD/100 outpatients per day. CONCLUSION: There was high consumption of antibiotics in the study setting. Based on the use control criteria, half of the antibiotics used were in the "Watch" group. The high level of consumptions of antibiotics, such as ciprofloxacin, norfloxacin, and azithromycin, in particular, requires further scrutiny and calls for an urgent implementation of an antibiotic stewardship program at the hospital.
RESUMO
BACKGROUND: Globally, over 3 million newborn die each year, one million of these attributed to infections. The objective of this study was to determine the etiologies and clinical characteristics of sepsis in neonates admitted to intensive care unit of a tertiary hospital in Ethiopia. METHODS: A longitudinal hospital based cohort study was conducted from April 1 to October 31, 2018 at the neonatal intensive care unit of Jimma Medical Center, southwest Ethiopia. Diagnosis of sepsis was established using the World Health Organization's case definition. Structured questionnaires and case specific recording formats were used to capture the relevant data. Venous blood and cerebrospinal fluid from neonates suspected to have sepsis were collected. RESULTS: Out of 304 neonates enrolled in the study, 195 (64.1%) had clinical evidence for sepsis, majority (84.1%; 164/195) of them having early onset neonatal sepsis. The three most frequent presenting signs and symptoms were fast breathing (64.6%; 122/195), fever (48.1%; 91/195) and altered feeding (39.0%; 76/195). Etiologic agents were detected from the blood culture of 61.2% (115/195) neonates. Bacterial pathogens contributed for 94.8% (109/115); the rest being fungal etiologies. Coagulase negative staphylococci (25.7%; 28/109), Staphylococcus aureus (22.1%; 24/109) and Klebsiella species (16.5%; 18/109) were the most commonly isolated bacteria. CONCLUSION: Majority of the neonates had early onset neonatal sepsis. The major etiologies isolated in our study markedly deviate from the usual organisms causing neonatal sepsis. Multicentre study and continuous surveillance are essential to tackle the current challenge to reduce neonatal mortality due to sepsis in Ethiopia.

BACKGROUND: In most African countries including Ethiopia, Neisseria gonorrhoeae infections were diagnosed clinically and its antibiotic susceptibility was rarely tested. This study aimed to determine the prevalence and antimicrobial susceptibility patterns of N. gonorrhoeae among suspected patients attending private clinics in Jimma, Ethiopia. METHODS: Institution-based cross-sectional study was conducted to determine the prevalence and antimicrobial susceptibility pattern of N. gonorrhoeae isolated from urogenital specimens. Urogenital samples were collected aseptically and then transported using Amie's transport media and processed in a microbiology laboratory following the standard protocol. RESULTS: Of the total 315 samples examined, 31 (9.8%) were confirmed to have gonococcal infection. Of these, 30 (96.7%) were females. High proportion of culture confirmed cases (18 (12.5%)) were observed in the 20-24 age group. All of the identified organisms were susceptible to ceftriaxone and had high resistance to penicillin (80.6%) and tetracycline (54.8%). CONCLUSION: The prevalence of gonococcal infection is high. In the current study, participants who have no information about sexually transmitted infection were more likely to be infected by N. gonorrhoeae. According to our study, ciprofloxacin is effective against gonococcal infection.
RESUMO
BACKGROUND: Human resources for health-care delivery are essential for attaining global health and development goals. Especially in developing countries, health extension workers are frontline health personnel who can play a key role in preventing and controlling HIV/AIDS. This study aimed to evaluate the performance of health extension workers in HIV-1/2 screening tests. Methodology. A comparative cross-sectional study was carried out to evaluate the performance of health extension workers in HIV-1/2 screening tests. Study participants had performed HIV screening tests on the prepared sample panels. Finally, the percentage of accuracy, error rate, sensitivity, specificity, predictive values, and measure of agreement (kappa) were calculated using SPSS version 26. RESULT: Totally, 1600 HIV screening tests were performed, and of these, 684 and 235 tests were done by HEWs (n = 15) and laboratory personnel (n = 5), respectively, with three discordant results by HEWs from a single sample panel which was weak reactive for HIV antibody test. The sensitivity, specificity, PPV, and NPV of HIV screening tests by HEWs were 97.4%, 100%, 100%, and 97.22%, respectively, and 100% for all parameters when it is tested by laboratory professionals. The measure of kappa agreement was 0.971 (95% CI, 0.932-1) for HEWs and 1 for laboratory personnel compared with the reference result. CONCLUSION: Based on this evidence, we conclude that the potential contribution of HEWs can be invaluable in the expansion of HIV screening tests nationwide to compensate the shortage of laboratory personnel.
RESUMO
Background: Neonatal sepsis is the third leading cause of neonatal mortality, behind prematurity and intrapartum-related complications. The main objectives of this study are to assess the proportion of sepsis in preterm newborns and identify the etiologic agents and their antibiotic sensitivity patterns. Methods: A longitudinal observational study was done from July 2016 to May 2018. Whenever clinical diagnosis of sepsis was made, blood cultures and antibiotic susceptibility tests were done. Result: We did 690 blood cultures, 255 (36.9%) showing bacterial growth. The most commonly isolated bacteria were Klebsiella species 78 (36.6%), Coagulase negative Staphylococcus 42 (19.7%) and Staphylococcus aureus 39 (18.3%). Gram-positive bacteria showed high resistance to penicillin (98.9%) and ceftriaxone (91.3%) whereas Gram-negative bacteria were highly resistant to gentamicin (83.2%) and ceftriaxone (83.2%). Conclusion: Resistance to the more commonly used antibiotics such as ampicillin and gentamycin was very high, necessitating reconsideration of the empiric use of these antibiotics.
RESUMO
Advances in neonatal care have led to the increasing survival of smaller and sicker infants, but nosocomial infections continue to be a serious problem, associated with increased mortality rates, immediate and long-term morbidity, prolonged hospital stay, and increased cost of care. We report a case of hospital-acquired sepsis in a preterm baby secondary to Klebsiella oxytoca, resulting from contaminated intravenous fluid.

BACKGROUND: Neonatal deaths now account for 47% of all deaths in children younger than 5 years globally. More than a third of newborn deaths are due to preterm birth complications, which is the leading cause of death. Understanding the causes and factors contributing to neonatal deaths is needed to identify interventions that will reduce mortality. We aimed to establish the major causes of preterm mortality in preterm infants in the first 28 days of life in Ethiopia. METHODS: We did a prospective, cross-sectional, observational study in five hospitals in Ethiopia. Study participants were preterm infants born in the study hospitals at younger than 37 gestational weeks. Infants whose gestational age could not be reliably estimated and those born as a result of induced abortion were excluded from the study. Data were collected on maternal and obstetric history, clinical maternal and neonatal conditions, and laboratory investigations. For neonates who died of those enrolled, consent was requested from parents for post-mortem examinations (both complete diagnostic autopsy and minimally invasive tissue sampling). An independent panel of experts established the primary and contributory causes of preterm mortality with available data. FINDINGS: Between July 1, 2016, to May 31, 2018, 4919 preterm infants were enrolled in the study and 3852 were admitted to neonatal intensive care units. By 28 days of post-natal age, 1109 (29%) of those admitted to the neonatal intensive care unit died. Complete diagnostic autopsy was done in 441 (40%) and minimally invasive tissue sampling in 126 (11%) of the neonatal intensive care unit deaths. The main primary causes of death in the 1109 infants were established as respiratory distress syndrome (502 [45%]); sepsis, pneumonia and meningitis (combined as neonatal infections; 331 [30%]), and asphyxia (151 [14%]). Hypothermia was the most common contributory cause of preterm mortality (770 [69%]). The highest mortality occurred in infants younger than 28 weeks of gestation (89 [86%] of 104), followed by infants aged 28-31 weeks (512 [54%] of 952), 32-34 weeks (349 [18%] of 1975), and 35-36 weeks (159 [8%] of 1888). INTERPRETATION: Three conditions accounted for 89% of all deaths among preterm infants in Ethiopia. Scale-up interventions are needed to prevent or treat these conditions. Further research is required to develop effective and affordable interventions to prevent and treat the major causes of preterm death. FUNDING: Bill & Melinda Gates Foundation.

BACKGROUND: Salmonella species are among the most common food borne pathogens worldwide and their infection is one of the major global public health problems. During the last decade, multidrug resistant Salmonella species have greatly increased in humans and animals. So the aim of this study was to determine prevalence and antibiotic susceptibility pattern of Salmonella in apparently healthy slaughterer cattle and personnel working at the Jimma abattoir. METHOD: A cross-sectional study was conducted from May to September 2016 at the Jimma abattoir. A total of 440 samples consisting of carcass swabs (n = 195), cattle feces (n = 195), and human stool (n = 50) were collected. Standard isolation and identification procedures were performed to identify Salmonella isolates. Antimicrobial susceptibility tests were also carried out on each isolate. RESULTS: The overall proportion of Salmonella positive isolates was 9.5% in all samples, of which 11.3% were from carcass swabs, 5.6% from cattle feces, and 18% from human stool. All isolates were resistant to tasted antibiotics except Ciprofloxacin. CONCLUSION: This study ascertains that Salmonella were widely distributed and significant proportions have developed resistance to routinely prescribed antibiotics. Therefore, there is needed to implement urgent intervention programs in study area.
