Risk Factors for Pulmonary Embolism in Individuals Infected with SARS-CoV2-A Single-Centre Retrospective Study.

The emergence of SARS-CoV2 has presented itself as a significant global health crisis. The prevalence of thrombotic events is known to be high in these patients, affecting various organ systems, sometimes leading to cutaneous thrombosis, pulmonary embolism (PE), stroke, or coronary thrombosis. The available evidence suggests that thromboembolism, hypercoagulability, and the excessive production of proinflammatory cytokines play a significant role in the development of multiorgan failure. Methodology: This retrospective single-centre study was conducted at "Victor Babes" University of Medicine and Pharmacy from Timisoara, Romania, involving a total of 420 patients diagnosed with COVID-19. We separated them into a CONTROL group that included 319 patients, and an intervention group (PE) with 101 patients that, subsequent to infection with the virus, developed pulmonary embolism. The study included the reporting of demographic data, laboratory findings, and comorbidities. Results: Out of a total of 420 patients, 24% experienced pulmonary embolism, while 21.42% died. Arterial thrombotic events were found to be associated with factors such as age, cardiovascular disease, levels of white blood cells, D-dimers, and albumin in the blood. The findings of the study indicate that there is an independent association between pulmonary thrombosis and hypertension (odds ratio (OR): 1.1; 95% confidence interval (CI): 0.7 to 1.7; p = 0.6463), cancer (OR: 1.1; 95% CI: 0.6 to 2.3; p = 0.6014), and COPD (OR: 1.2; 95% CI: 0.6 to 2.3; p = 0.4927). On the other hand, there is a stronger correlation between PE and obesity (OR: 2.8; 95% CI: 1.7 to 4.6; p < 0.0001), diabetes (OR: 3.3; 95% CI: 2 to 5.3; p < 0.0001), and dyslipidemia (OR: 3.6; 95% CI: 2.3 to 5.8; p < 0.0001) in a multivariable regression logistic model. Conclusions: Patients diagnosed with severe forms of COVID-19 display a comparable incidence of arterial thrombotic events, which have been linked to poor survival rates.

Post-Infection Oscillometry and Pulmonary Metrics in SARS-CoV-2 Patients: A 40-Day Follow-Up Study.

The COVID-19 pandemic, caused by the SARS-CoV-2 virus, has had significant impacts on pulmonary function. This study aimed to comprehensively evaluate pulmonary function and structure in patients 40 days post-SARS-CoV-2 infection, employing an array of testing methodologies including spirometry, plethysmography, forced oscillometry, and CT scanning. It also sought to establish potential correlations between these metrics and evaluate if forced oscillometry could provide additional value in post-infective lung function assessment. A 40-day post-infection follow-up observational study was conducted involving 66 patients with confirmed SARS-CoV-2 infection. The results revealed decreases in FVC and FEF25-75 with the increasing severity of COVID-19. Specifically, patients with severe symptoms exhibited statistically significant decreases in FVC (mean = 86.8) compared with those with mild symptoms (mean = 106.0; p = 0.018). The FEF25-75 showed a similar trend, with severe patients exhibiting a mean of 77.7 compared with 82.9 in the mild group (p = 0.017). Furthermore, resonant frequency (RF) increased with disease severity, with the severe group exhibiting a statistically significant increase (mean = 17.4) compared with the mild group (mean = 14.3; p = 0.042). CT scans showed an increase in ground-glass opacities with disease severity, with 81.8% of severe patients demonstrating this finding (p = 0.037). Multiple regression analysis revealed that Reactance at 4 Hz (X4), Forced Expiratory Flow 25-75% (FEF25-75), and Resonant Frequency (RF) were significantly related to COVID-19 severity. Specifically, for each unit increase in these factors, the risk of the event was estimated to increase by a factor of 3.16, 2.09, and 1.90, respectively. Conversely, Resistance at 4 Hz (R4) and Airway Resistance (RAW) were found to significantly decrease the event hazard, highlighting their potential protective role. Spirometry, plethysmography, and forced oscillometry are effective in assessing these changes. Forced oscillometry may be particularly beneficial in identifying subtle changes in lung function post-COVID-19. Further studies are warranted to validate these findings and develop strategies to manage post-infective pulmonary changes in SARS-CoV-2 patients.

A Retrospective Assessment of Sputum Samples and Antimicrobial Resistance in COVID-19 Patients.

Data on bacterial or fungal pathogens and their impact on the mortality rates of Western Romanian COVID-19 patients are scarce. As a result, the purpose of this research was to determine the prevalence of bacterial and fungal co- and superinfections in Western Romanian adults with COVID-19, hospitalized in in-ward settings during the second half of the pandemic, and its distribution according to sociodemographic and clinical conditions. The unicentric retrospective observational study was conducted on 407 eligible patients. Expectorate sputum was selected as the sampling technique followed by routine microbiological investigations. A total of 31.5% of samples tested positive for Pseudomonas aeruginosa, followed by 26.2% having co-infections with Klebsiella pneumoniae among patients admitted with COVID-19. The third most common Pathogenic bacteria identified in the sputum samples was Escherichia coli, followed by Acinetobacter baumannii in 9.3% of samples. Commensal human pathogens caused respiratory infections in 67 patients, the most prevalent being Streptococcus penumoniae, followed by methicillin-sensitive and methicillin-resistant Staphylococcus aureus. A total of 53.4% of sputum samples tested positive for Candida spp., followed by 41.1% of samples with Aspergillus spp. growth. The three groups with positive microbial growth on sputum cultures had an equally proportional distribution of patients admitted to the ICU, with an average of 30%, compared with only 17.3% among hospitalized COVID-19 patients with negative sputum cultures (p = 0.003). More than 80% of all positive samples showed multidrug resistance. The high prevalence of bacterial and fungal co-infections and superinfections in COVID-19 patients mandates for strict and effective antimicrobial stewardship and infection control policies.

Dental-Plaque Decontamination around Dental Brackets Using Antimicrobial Photodynamic Therapy: An In Vitro Study.

BACKGROUND: In orthodontic therapy, the enamel around brackets is very susceptible to bacterial-plaque retention, which represents a risk factor for dental tissues. The aim of this study was to evaluate the effect of methylene blue and a chlorophyllin-phycocyanin mixture, used with and without light activation, in contrast with a 2% chlorhexidine solution, on Streptococcus mutans colonies. METHODS: Twenty caries-free human extracted teeth were randomized into five groups. A Streptococcus mutans suspension was inoculated on teeth in groups B, C, D, and E (A was the positive-control group). Bacterial colonies from groups C, D, and E (B was the negative-control group) were subjected to photosensitizers and 2% chlorhexidine solution. For groups C and D, a combined therapy consisting of photosensitizer and light activation was performed. The Streptococcus mutans colonies were counted, and smears were examined with an optical microscope. Two methods of statistical analysis, unidirectional analysis of variance and the Tukey-Kramer test, were used to evaluate the results. RESULTS: A statistically significant reduction in bacterial colonies was detected after the combined therapy was applied for groups C and D, but the most marked bacterial reduction was observed for group D, where a laser-activated chlorophyll-phycocyanin mixture was used. CONCLUSIONS: Photodynamic therapy in combination with methylene blue or chlorophyllin-phycocyanin mixture sensitizers induces a statistically significant decrease in the number of bacterial colonies.

Long noncoding RNAs may impact podocytes and proximal tubule function through modulating miRNAs expression in Early Diabetic Kidney Disease of Type 2 Diabetes Mellitus patients.

Aims: Long noncoding RNAs (lncRNAs) play key roles in the pathophysiology of DKD involving actions of microRNAs (miRNAs). The aims of the study were to establish the involvement of selected lncRNAs in the epigenetic mechanisms of podocyte damage and tubular injury in DKD of type 2 diabetes mellitus (DM) patients in relation to a particular miRNAs profile. Methods: A total of 136 patients with type 2 DM and 25 healthy subjects were assessed in a cross-sectional study concerning urinary albumin: creatinine ratio (UACR), eGFR, biomarkers of podocyte damage (synaptopodin, podocalyxin) and of proximal tubule (PT) dysfunction (Kidney injury molecule-1-KIM-1, N-acetyl-D-glucosaminidase-NAG), urinary lncRNA metastasis-associated lung adenocarcinoma transcript 1 (MALAT1), nuclear-enriched abundant transcript 1 (NEAT1), myocardial infarction-associated transcript (MIAT), taurine-upregulated gene 1 (TUG1), urinary miRNA21, 124, 93, 29a. Results: Multivariable regression analysis showed that urinary lncMALAT1 correlated directly with urinary synaptopodin, podocalyxin, KIM-1, NAG, miRNA21, 124, UACR, and negatively with eGFR, miRNA93, 29a (p<0.0001; R2=0.727); urinary lncNEAT1 correlated directly with synaptopodin, KIM-1, NAG, miRNA21, 124, and negatively with eGFR, miRNA93, 29a (p<0.0001; R2=0.702); urinary lncMIAT correlated directly with miRNA93 and 29a, eGFR (p<0.0001; R2=0.671) and negatively with synaptopodin, KIM-1, NAG, UACR, miRNA21, 124 (p<0.0001; R2=0.654); urinary lncTUG1 correlated directly with eGFR, miRNA93, 29a, and negatively with synaptopodin, podocalyxin, NAG, miRNA21, 124 (p<0.0001; R2=0.748). Conclusions: In patients with type 2 DM lncRNAs exert either deleterious or protective functions within glomeruli and PT. LncRNAs may contribute to DKD through modulating miRNAs expression and activities. This observation holds true independently of albuminuria and DKD stage.

Smartphone Use and Postural Balance in Healthy Young Adults.

Maintaining an upright posture while talking or texting on the phone is a frequent dual-task demand. Using a within-subjects design, the aim of the present study was to assess the impact of a smartphone conversation or message texting on standing plantar pressure and postural balance performance in healthy young adults. Thirty-five subjects (mean age 21.37 ± 1.11 years) were included in this study. Simultaneous foot plantar pressure and stabilometric analysis were performed using the PoData system, under three conditions: no phone (control), talking on a smartphone (talk) and texting and sending a text message via a smartphone (text). Stabilometric parameters (center of pressure (CoP) path length, 90% confidence area and maximum CoP speed) were significantly affected by the use of different smartphone functions (p < 0.0001). The CoP path length and maximum CoP speed were significantly higher under the talk and text conditions when compared to the control. CoP path length, 90% confidence area and maximum CoP speed were significantly increased in talk compared to text and control. Talking on the phone also influenced the weight distribution on the left foot first metatarsal head and heel as compared with message texting. Postural stability in healthy young adults was significantly affected by talking and texting on a smartphone. Talking on the phone proved to be more challenging.

Intensive care antibiotic consumption and resistance patterns: a cross-correlation analysis.

BACKGROUND: Over recent decades, a dramatic increase in infections caused by multidrug-resistant pathogens has been observed worldwide. The aim of the present study was to investigate the relationship between local resistance bacterial patterns and antibiotic consumption in an intensive care unit in a Romanian university hospital. METHODS: A prospective study was conducted between 1st January 2012 and 31st December 2013. Data covering the consumption of antibacterial drugs and the incidence density for the main resistance phenotypes was collected on a monthly basis, and this data was aggregated quarterly. The relationship between the antibiotic consumption and resistance was investigated using cross-correlation, and four regression models were constructed, using the SPSS version 20.0 (IBM, Chicago, IL) and the R version 3.2.3 packages. RESULTS: During the period studied, the incidence of combined-resistant and carbapenem-resistant P. aeruginosa strains increased significantly [(gradient = 0.78, R2 = 0.707, p = 0.009) (gradient = 0.74, R2 = 0.666, p = 0.013) respectively], mirroring the increase in consumption of ß-lactam antibiotics with ß-lactamase inhibitors (piperacillin/tazobactam) and carbapenems (meropenem) [(gradient = 10.91, R2 = 0.698, p = 0.010) and (gradient = 14.63, R2 = 0.753, p = 0.005) respectively]. The highest cross-correlation coefficients for zero time lags were found between combined-resistant vs. penicillins consumption and carbapenem-resistant P. aeruginosa strains vs. carbapenems consumption (0.876 and 0.928, respectively). The best model describing the relation between combined-resistant P. aeruginosa strains and penicillins consumption during a given quarter incorporates both the consumption and the incidence of combined-resistant strains in the hospital department during the previous quarter (multiple R2 = 0.953, p = 0.017). The best model for explaining the carbapenem resistance of P. aeruginosa strains based on meropenem consumption during a given quarter proved to be the adjusted model which takes into consideration both previous consumption and incidence density of strains during the previous quarter (Multiple R2 = 0.921, p = 0.037). CONCLUSIONS: The cross-correlation coefficients and the fitted regression models provide additional evidence that resistance during the a given quarter depends not only on the consumption of antibacterial chemotherapeutic drugs in both that quarter and the previous one, but also on the incidence of resistant strains circulating during the previous quarter.

Antimicrobial consumption, costs and resistance patterns: a two year prospective study in a Romanian intensive care unit.

BACKGROUND: Due to the vulnerable nature of its patients, the wide use of invasive devices and broad-spectrum antimicrobials used, the intensive care unit (ICU) is often called the epicentre of infections. In the present study, we quantified the burden of hospital acquired pathology in a Romanian university hospital ICU, represented by antimicrobial agents consumption, costs and local resistance patterns, in order to identify multimodal interventional strategies. METHODS: Between 1st January 2012 and 31st December 2013, a prospective study was conducted in the largest ICU of Western Romania. The study group was divided into four sub-samples: patients who only received prophylactic antibiotherapy, those with community-acquired infections, patients who developed hospital acquired infections and patients with community acquired infections complicated by hospital-acquired infections. The statistical analysis was performed using the EpiInfo version 3.5.4 and SPSS version 20. RESULTS: A total of 1596 subjects were enrolled in the study and the recorded consumption of antimicrobial agents was 1172.40 DDD/ 1000 patient-days. The presence of hospital acquired infections doubled the length of stay (6.70 days for patients with community-acquired infections versus 16.06/14.08 days for those with hospital-acquired infections), the number of antimicrobial treatment days (5.47 in sub-sample II versus 11.18/12.13 in sub-samples III/IV) and they increased by 4 times compared to uninfected patients. The perioperative prophylactic antibiotic treatment had an average length duration of 2.78 while the empirical antimicrobial therapy was 3.96 days in sample II and 4.75/4.85 days for the patients with hospital-acquired infections. The incidence density of resistant strains was 8.27/1000 patient-days for methicilin resistant Staphylococcus aureus, 7.88 for extended spectrum ß-lactamase producing Klebsiella pneumoniae and 4.68/1000 patient-days for multidrug resistant Acinetobacter baumannii. CONCLUSIONS: Some of the most important circumstances collectively contributing to increasing the consumption of antimicrobials and high incidence densities of multidrug-resistant bacteria in the studied ICU, are represented by prolonged chemoprophylaxis and empirical treatment and also by not applying the definitive antimicrobial therapy, especially in patients with favourable evolution under empirical antibiotic treatment. The present data should represent convincing evidence for policy changes in the antibiotic therapy.

Urinary tract infections in Romanian patients with diabetes: prevalence, etiology, and risk factors.

AIM: Patients with diabetes mellitus (DM) have an increased risk of infections, especially urinary tract infections (UTIs). The aim of this study was to assess the prevalence and etiology of UTIs and identify the risk factors for their development in patients with DM. PATIENTS AND METHODS: In this retrospective, noninterventional study, the medical records of 2,465 adult patients with DM who were hospitalized in a Diabetes Clinic were reviewed. Data regarding the presence of UTI and possible associated risk factors were collected and their possible relation was analyzed. The study protocol and procedures were approved by the Ethics Committee of Timișoara Emergency Hospital. All data were collected and analyzed using SPSS v.17 statistical software. RESULTS: The prevalence of UTIs in patients with DM was 12.0% (297 cases), being higher in females than in males and higher in patients with type 2 DM compared with patients with type 1 DM. In univariate logistic regression analysis, risk factors associated with UTIs were female gender, age, type 2 DM, longer duration of DM, and the presence of chronic kidney disease and coronary artery disease. Multivariate analysis identified age, duration of DM, and metabolic control (hemoglobin A1c levels) as independent risk factors for UTIs. The gram-negative bacilli from the Enterobacteriaceae family were predominant, with Escherichia coli being the most frequent of them (70.4%). CONCLUSION: UTIs are a frequent condition associated with DM. It is necessary to improve the care and the screening of UTIs in patients with DM to prevent the occurrence of possible associated severe renal complications.

Germinated and Ungerminated Seeds Extract from Two Lupinus Species: Biological Compounds Characterization and In Vitro and In Vivo Evaluations.

In recent years, nutraceuticals attracted a great amount of attention in the biomedical research due to their significant contribution as natural agents for prevention of various health issues. Ethanolic extracts from the ungerminated and germinated seeds of Lupinus albus L. and Lupinus angustifolius L. were analyzed for the content in isoflavones (genistein) and cinnamic acid derivatives. Additionally, the extracts were evaluated for antimicrobial, antiproliferative, and anti-inflammatory properties, using in vitro and in vivo tests. Germination proved to be a method of choice in increasing the amount of genistein and cinnamic acid derivatives in both Lupinus albus L. and Lupinus angustifolius L. seeds. Biological evaluation of all vegetal extracts revealed a weak therapeutic potential for both ungerminated and germinated seeds.

[Aminoglycoside resistance of enterobacteria isolated from urinary infections in surgical departments]. / Rezistenta la aminoglicozide a enterobacteriilor izolate din infectii urinare în sectii cu profil chirurgical.

The aim of the study was to determine the aminoglycosides resistance of Enterobacteriaceae strains isolated from urocultures. Identification of the germs was performed by the API system (BioMerieux) and susceptibility tests was performed by disk-diffusion test (CLSI standards) and with API strips. For detecting the resistance to aminoglycosides we used gentamicin, tobramycin, netilmicin and amikacin. From 2500 urine samples we isolated 673 microbial strains, from which 531 were Enterobacteriaceae, especially E. coli, 57.62% and Klebsiella pneumoniae pneumoniae, 27.68% strains. We observed natural maintained sensibility to aminoglycosides at 55.17% from all the strains we have studied The high prevalence of aminoglycosides resistance of Enterobacteriaceae strains is explained by prolonged antibiotic therapy of patients with invasive diagnostic and therapeutic procedures. A rational policy in prescribing antibiotics in this department is therefore mandatory.

[Phenotypic characterization of Streptococcus agalactiae strains isolated from urocultures]. / Caracterizarea fenotipica a unor tulpini de Streptococcus agalactiae izolate din uroculturi.

UNLABELLED: The aim of this study was to determine the antibiotic resistance of Streptococcus agalactiae strains isolated from urocultures in order to obtain new data regarding circulating phenotypes in Urology Department. METHODS: For identifications of Streptococcus agalactiae strains we used Pastorex Strep (BioRad). The sensitivity of isolated germs to antimicrobials was tested using standardised Kirby-Bauer technique. RESULTS: We isolated 21 Streptococcus agalactiae strains from 1871 urocultures. Analyzing the extended antibiograms we categorized these germs according with their resistance phenotypes and we remarked a high percentage of wild type phenotype Streptococcus agalactiae strains (80.95%). CONCLUSIONS: Streptococcus agalactiae strains are more rarely isolated from hospital acquired urinary tract infections, that's way we can explain the low resistance of these strains.

[Considerations regarding the nosocomial potential of surgical wards]. / Consideratii referitoare la potentialul nosocomial al sectiilor de chirurgie.

PURPOSES: The aim of our study was to determine the prevalence of multiresistant germs with nosocomial potential and their main resistance phenotype and genotype patterns in surgical departments. METHODS: Identification of germs was performed by the API system (BioMerieux France) and susceptibility tests by disk-diffusion tests, (CLSI standards) with automatic reading methods (Osiris-Bio Rad Laboratories). ESBL producing E. coli and Klebsiella pneumoniae strains have been also genotyped. RESULTS: From 190 samples (urines, wound secretions, blood, etc.); we isolated 106 microbial strains with nosocomial potential. 56 (52.83%) from these strains were represented by enterobacteria, 26 (24.52%) by Gram negative non-fermentative rods, and 24 (22.64%) by Gram positive cocci. CONCLUSIONS: We noticed a high prevalence of multidrug resistant germs (ESBL, MRSA, etc). The majority of them were involved in nosocomial surgical site and urinary tract infections.

The establishment of resistance phenotypes for bacteria isolated from outpatients in urine cultures.

From 1911 outpatients, who addressed a Timisoara private clinical laboratory, from January to December 2005, we collected 1,889 urine cultures, 431 being positive. Bacteria identification was generally done using morphological, cultural, biochemical characters and pathogenicity tests. Sensitivity testing to antimicrobial medical drugs was done by using the classical diffusion Kirby-Bauer method and the automatic analyzer Osiris, also. The main bacteria involved in the etiology of these infections were represented by Enterobacteriaceae, head of the list being Escherichia coli (81.21%), followed by Klebsiella pneumoniae (8.35%) and Proteus mirabilis (3.02%). We also isolated Gram positive cocci (in a much smaller proportion), mainly represented by Enterococcus faecalis (1.16%), Staphylococcus aureus (0.93%), Streptococcus agalactiae, and also Gram negative non-fermentative bacilli, such as Pseudomonas aeruginosa (0.93%) or Acinetobacter baumanii (0.23%). As soon as we performed the sensitivity tests, we divided them in resistance phenotypes: Most of the Enterobacteriaceae were integrated in the wild phenotype, followed by the penicillinase producing phenotype. An E. coli strain (0.29%) and 3 Klebsiella pneumoniae strains (8.33%) were integrated in the large spectrum, multidrug resistant, beta-lactamase producing phenotype, also associated with resistance to fluoroquinolones and aminoglycosides; Non-fermentative bacilli did not present special resistance problems, the four Pseudomonas aeruginosa strains were integrated in the wild phenotype (secreting induced chromosomal cephalosporinase). As for Staphylococcus aureus it was identified a strain having fluoroquinolone resistance, two strains secreting penicillinase and having a K (Nm) phenotype and a strain secreting penicillinase only. Antibiotic resistance represents a major concern for patients, physicians, healthcare managers, and policymakers. The use of antibiotics is closely linked with the development of acquired antibiotic resistance.

[The sensitivity of some strains of Klebsiella spp. collected in a neonatal department]. / Sensibilitatea unor tulpini de Klebsiella izolate într-o sectie de nou-nascuti.

In order to analyse the evolution of the sensitivity to antibiotics of same strains with nosocomial potential such as Klebsiella isolated in a hospital, we took into study a number of 976 samples, collected in a new-born care department of the "Dr. D. Popescu" hospital Timisoara. The study took place between November-December 2002. The collected samples were pharyngeal swabs, nasal swabs, gastric aspirates, ocular and umbilical secretions, vernix, urines, faeces and blood. From all these samples 803 strains with nosocomial potential were isolated, 84 strains being Klebsiella spp. Most of the isolated strains presented multiple phenotypes of resistance to antibiotics.

[Incidence and sensitivity to antibiotics of germs isolated from surgical wound infections]. / Studiu privind incidenta si sensibilitatea la antibiotice a germenilor izolati din infectii postoperatorii de plaga chirurgicala.

We studied 119 bacterial strains isolated from postoperative infected wounds. All these strains were considered to be strains that derived from the same number of nosocomial infections, all the postoperative infections of the wounds being nosocomial infections. Regarding their frequency, we isolated the following strains: E. coli--68 strains (57%), S. aureus--37 strains (31%), Pseudomonas spp.--9 strains (8%) and Proteus spp.--5 strains (4%). We performed the bacteriological study of these strains and some correlations between them and the surgical diagnosis. In order to help the surgical therapy of the overinfected wounds, we tested the drug sensitivity of all these strains. The results regarding the drug sensitivity show that these strains have different types of resistance to antibiotics, the Pseudomonas strains being the most resistant. We noticed a continuous decrease of the sensitivity of the isolated strains to certain antimicrobial drugs, and this focuses the attention on the necessity of monitoring the antibiotic prescriptions in hospitals. Taking into account the results obtained after this study, we should reconsider the concept of nosocomial infections control through prevention activities, in order to reduce the incidence and to identify the potential causes that can lead to nosocomial infections.

[Evaluation of the sensitivity to meropenem of some bacterial strains with nosocomial potential]. / Evaluarea sensibilitatii la meropenem a unor tulpini bacteriene cu potential nosocomial.

This study analyzes the sensitivity to meropenem of 880 bacterial strains isolated from hospitalized patients in various medical units of County Hospital No. 1 Timisoara. As a result, a high sensitivity of gram-negative pathogens to meropenem (82.01%) has been noticed. Among Enterobacteriaceae, 93.17% of Escherichia coli and 71% of Klebsiella sp. were susceptible to meropenem. For Pseudomonas aeruginosa strains, a high susceptibility was noticed to meropenem (91%), more than 70% to imipenem, but piperacillin + tazobactam had 42% resistance rates.

[Bacterial strains isolated in high nosocomial risk departments]. / Tulpini microbiene izolate din sectii cu risc nosocomial crescut.

We collected 312 samples from hospitalized patients in two hospitals in Timisoara between September-December 2003. We isolated 83 strains with nosocomial potential. Identification of the germs was performed using the automatic API system, and the susceptibility tests were performed using disc-diffusion and the agar dilution test. By analyzing the extended antibiograms we categorized the germs considering their phenotypes of resistance and we remarked a high percentage of E. coli, Klebsiella pneumoniae pneumoniae and S. aureus with multiple resistance to antibiotics.
