Human Exposure to Naturally Occurring Bacillus anthracis in the Kars Region of Eastern Türkiye.

Environmental contamination with Bacillus anthracis spores poses uncertain threats to human health. We undertook a study to determine whether inhabitants of the anthrax-endemic region of Kars in eastern Türkiye could develop immune responses to anthrax toxins without recognised clinical infection. We measured anti-PA and anti-LF IgG antibody concentrations by ELISA in serum from 279 volunteers, 105 of whom had previously diagnosed anthrax infection (100 cutaneous, 5 gastrointestinal). Of the 174 without history of infection, 72 had prior contact with anthrax-contaminated material. Individuals were classified according to demographic parameters, daily working environment, and residence type. All villages in this study had recorded previous animal or human anthrax cases. Stepwise regression analyses showed that prior clinical infection correlated strongly with concentrations at the upper end of the ranges observed for both antibodies. For anti-PA, being a butcher and duration of continuous exposure risk correlated with high concentrations, while being a veterinarian or shepherd, time since infection, and town residence correlated with low concentrations. For anti-LF, village residence correlated with high concentrations, while infection limited to fingers or thumbs correlated with low concentrations. Linear discriminant analysis identified antibody concentration profiles associated with known prior infection. Profiles least typical of prior infection were observed in urban dwellers with known previous infection and in veterinarians without history of infection. Four individuals without history of infection (two butchers, two rural dwellers) had profiles suggesting unrecognised prior infection. Healthy humans therefore appear able to tolerate low-level exposure to environmental B. anthracis spores without ill effect, but it remains to be determined whether this exposure is protective. These findings have implications for authorities tasked with reducing the risk posed to human health by spore-contaminated materials and environments.

Severe and complicated soft tissue infections: a single-centre case series.

OBJECTIVE: To assess the demographic and clinical characteristics, laboratory findings, and economic burden of patients with a diagnosis of complicated skin and soft tissue infection (cSSTI). METHOD: The demographic and clinical characteristics, laboratory findings, surgical interventions, cost of treatment, and outcome of patients diagnosed with cSSTIs between January 2017 and December 2019 were retrospectively analysed. RESULTS: A total of 24 patients with cSSTIs were included in the study. The median age was 53 (22-85) years, and 14 (58%) were female. The most common comorbidity was diabetes (54%). On admission, 75% of patients presented with sepsis, and 70% had a high-grade Laboratory Risk Indicator for Necrotising Fasciitis (LRINEC) score. The causative microorganism was isolated from 21 (87%) patients, and the multidrug resistance rate of Gram-negative bacteria was 50%. The median number of debridements was 3 (1-12). In all, 11 patients were followed up in the intensive care unit, and the mortality rate was 29%. The presence of confusion (p=0.025), causative Gram-negative microorganisms (p=0.009), hyponatraemia (p=0.034), the need for intensive care (p=0.001), anti-meticillin-resistant Staphylococcus aureus antibiotics (p=0.023) and the rate of antibiotic changes during treatment (p=0.019) were significantly higher in the non-survival patient group. Hyponatraemia was a significant independent risk factor for mortality (p=0.048). The median cost of per-patient treatment was $9453 USD in the non-surviving and $1536 in the surviving group. CONCLUSION: It is important to know possible factors and local resistance rates at the beginning of empirical antibacterial and surgical treatment. The presence of hyponatraemia, sepsis and a high LRINEC score can be considered to be the mortality predictors.

Human Anthrax: Update of the Diagnosis and Treatment.

Anthrax is one of the most important zoonotic diseases which primarily infects herbivores and occasionally humans. The etiological agent is Bacillus anthracis which is a Gram-positive, aerobic, spore-forming, nonmotile, rod-shaped bacillus. The spores are resistant to environmental conditions and remain viable for a long time in contaminated soil, which is the main reservoir for wild and domestic mammals. Infections still occur in low-income countries where they cause suffering and economic hardship. Humans are infected by contact with ill or dead animals, contaminated animal products, directly exposed to the spores in the environment or spores released as a consequence of a bioterrorist event. Three classical clinical forms of the disease, cutaneous, gastrointestinal and inhalation, are seen, all of which can potentially lead to sepsis or meningitis. A new clinical form in drug users has been described recently and named "injectional anthrax" with high mortality (>33%). The symptoms of anthrax in the early stage mimics many diseases and as a consequence it is important to confirm the diagnosis using a bacterial culture or a molecular test. With regards to treatment, human isolates are generally susceptible to most antibiotics with penicillin G and amoxicillin as the first choice, and ciprofloxacin and doxycycline serving as alternatives. A combination of one or more antibiotics is suggested in systemic anthrax. Controlling anthrax in humans depends primarily on effective control of the disease in animals. Spore vaccines are used in veterinary service, and an acellular vaccine is available for humans but its use is limited.

A subtractive proteomics approach for the identification of immunodominant Acinetobacter baumannii vaccine candidate proteins.

Background: Acinetobacter baumannii is one of the most life-threatening multidrug-resistant pathogens worldwide. Currently, 50%-70% of clinical isolates of A. baumannii are extensively drug-resistant, and available antibiotic options against A. baumannii infections are limited. There is still a need to discover specific de facto bacterial antigenic proteins that could be effective vaccine candidates in human infection. With the growth of research in recent years, several candidate molecules have been identified for vaccine development. So far, no public health authorities have approved vaccines against A. baumannii. Methods: This study aimed to identify immunodominant vaccine candidate proteins that can be immunoprecipitated specifically with patients' IgGs, relying on the hypothesis that the infected person's IgGs can capture immunodominant bacterial proteins. Herein, the outer-membrane and secreted proteins of sensitive and drug-resistant A. baumannii were captured using IgGs obtained from patient and healthy control sera and identified by Liquid Chromatography- Tandem Mass Spectrometry (LC-MS/MS) analysis. Results: Using the subtractive proteomic approach, we determined 34 unique proteins captured only in drug-resistant A. baumannii strain via patient sera. After extensively evaluating the predicted epitope regions, solubility, transverse membrane characteristics, and structural properties, we selected several notable vaccine candidates. Conclusion: We identified vaccine candidate proteins that triggered a de facto response of the human immune system against the antibiotic-resistant A. baumannii. Precipitation of bacterial proteins via patient immunoglobulins was a novel approach to identifying the proteins that could trigger a response in the patient immune system.

Impact of HLA Polymorphism on the Immune Response to Bacillus Anthracis Protective Antigen in Vaccination versus Natural Infection.

The causative agent of anthrax, Bacillus anthracis, evades the host immune response and establishes infection through the production of binary exotoxins composed of Protective Antigen (PA) and one of two subunits, lethal factor (LF) or edema factor (EF). The majority of vaccination strategies have focused upon the antibody response to the PA subunit. We have used a panel of humanised HLA class II transgenic mouse strains to define HLA-DR-restricted and HLA-DQ-restricted CD4+ T cell responses to the immunodominant epitopes of PA. This was correlated with the binding affinities of epitopes to HLA class II molecules, as well as the responses of two human cohorts: individuals vaccinated with the Anthrax Vaccine Precipitated (AVP) vaccine (which contains PA and trace amounts of LF), and patients recovering from cutaneous anthrax infections. The infected and vaccinated cohorts expressing different HLA types were found to make CD4+ T cell responses to multiple and diverse epitopes of PA. The effects of HLA polymorphism were explored using transgenic mouse lines, which demonstrated differential susceptibility, indicating that HLA-DR1 and HLA-DQ8 alleles conferred protective immunity relative to HLA-DR15, HLA-DR4 and HLA-DQ6. The HLA transgenics enabled a reductionist approach, allowing us to better define CD4+ T cell epitopes. Appreciating the effects of HLA polymorphism on the variability of responses to natural infection and vaccination is vital in planning protective strategies against anthrax.

The Effect of Mesenchymal Stromal Cells on the Mortality of Patients with Sepsis and Septic Shock: A Promising Therapy.

Purpose: Sepsis and septic shock are the major causes of death in intensive care units. This study aimed to evaluate the clinical safety and efficacy of mesenchymal stem cells (MSCs) in sepsis and septic shock patients. Methods: Ten patients were enrolled in the study. Adipose-derived MSC infusions were given (1 × 106/kg, on the 1st, 3rd, 5th, 7th, and 9th days of therapy) together with standard therapy. Before the MSC applications, blood samples were collected for cytokine assessment (TNF-α, IFN-γ, IL-2, IL-4, IL-6, IL-10). The clinical and laboratory improvements were recorded and compared with control groups selected retrospectively. The clinical trial was registered on 16.03.2022 with the registration number NCT05283317. Results: In the study group, the ages of patients ranged from 22 to 68 years, and APACHE II scores ranged from 14 to 42. In the control group, ages ranged from 22 to 80 years and their APACHE II scores were between 14-35. The survival rate in the study group was 100% on the 14th day whereas it was 70% on the 28th day. A significant decrease in the SOFA score (adjusted), clinical, and laboratory improvements were observed during the MSC administration. However, no significant cytokine level changes were observed. In the control group, the survival rate of 20 patients was 70% on the 14th day, whereas 60% was on the 28th day. While deaths were observed in the control group in the first week of treatment, deaths in the MSCs group were observed between the 15th and 28th days. Conclusion: MSCs treatment may have a positive impact on the survival rates of sepsis during the early phase. However, further randomized controlled studies with a large group of patients are needed. Trial Registration. This trial is registered with ClinicalTrials.gov Identifier: NCT05283317.

Medical conditions of Omer Seyfettin (1884-1920), the father of Turkish short stories, enshrined as a mystery.

Born in 1884 in Balikesir, Turkey, Ömer Seyfettin was a leading figure among modern Turkish short story writers whose death in 1920 at the age of 36 led to long-term speculations about his fatal illness. In order to pay homage to his memory in the centennial of his death and to shed light on his later medical condition, this paper seeks to reexamine his last days from a medico-historical perspective. Our findings indicate that there was a notable decline in his health occurring after 1917 when he was confined to social isolation. A carbuncle was diagnosed in his posterior neck when he was 35-years of age and not satisfactorily treated. In late February 1920, he developed progressive symptoms over two weeks consisting initially of a headache, followed by fever, delirium, hallucinations, and diplopia. These clinical signs and symptoms are clinically suggestive of a septic encephalopathy presumably caused by staphylococcus aureus infection secondary to the carbuncle, or perhaps by one of the myriad causes of viral meningoencephalitis.

Coronavirus disease 2019 vaccine: An overview of the progression and current use.

On December 31, 2019; unidentified pneumonia cases were reported from China. It was soon announced that these cases were of viral origin and the cause was a new coronavirus (CoV). Initially, the virus was called "novel CoV " and then defined as "severe acute respiratory syndrome CoV 2 (SARS-CoV-2)" after more detailed investigations. The disease caused by SARS-CoV-2 was named CoV disease 2019 (COVID-19) by the World Health Organization. The rapid spread of the disease in a few months has resulted in a global pandemic and it continues. However, there are no specific effective anti-viral drugs for SARS-CoV-2 infection, some antiviral drugs are using in the therapy of COVID-19 with limited success. Currently, for the prevention of the pandemic, global vaccination seems to be important. Antiviral protection of vaccines is provided by the development of antibodies that can neutralize the virus. Antibody response develops against spike protein and nucleocapsid protein but neutralizing antibodies are formed against the receptor-binding domain of the spike protein. It has also been shown that most viral proteins are recognized in T-cell responses. Vaccine discovery trials for COVID-19 have begun all over the world since the outbreak began. More than 100 vaccine studies against COVID-19 have been published in the last year. Some of them were urgently approved and used worldwide. The current study aimed to review the progression and current use of COVID-19 vaccines.

The investigation of adrenal involvement in carbapenem resistant Acinetobacter baumannii sepsis: experimental mouse model

Background/aim: In the last years, incidence of carbapenem resistant Acinetobacter baumannii sepsis is increasing with high mortality. However, it is not clear whether this is due to inadequate antimicrobial choice or a more severe clinical course. We aimed to evaluate the inflammation and adrenal involvement in the carbapenem resistant A. baumannii by using experimental mouse model sepsis. Materials and methods: Balb/c female mice were randomly put into control and three sepsis groups ( A. baumannii susceptible to carbapenem-CSAB-, A. baumannii resistant to carbapenem-CRAB-, Escherichia coli). A total of sixty mice were included in this study with each group having 15 mice. Mice were sacrificed 72 h after bacterial inoculation, and blood was taken from each mouse for the assessment of cytokines and corticosterone. Both adrenal glands were dissected; one was used for culture and the other was used for histopathological examination. Bacterial loads of organs were calculated as CFU/g. The histopathological changes, bacterial levels in adrenal and cytokine and corticosterone levels were assessed and compared among the groups. Results: The bacterial level was higher in E. coli (108, 45 ±30, 55 log10 CFU/g) (mean±SD) than other sepsis groups. The lowest level of corticosterone was observed in the E. coli group (p < 0.001). TNF alpha level was highest in the CRAB and E. coli group and this difference was statistically significant than control group (p < 0.05). The IL-6 level in CRAB was significantly higher than the control group (10, 20 pg/mL). The adrenal gland congestion was significantly severe in all the sepsis groups compared to the control. In the group comparison, congestion was significantly more severe in the E. coli group than in CSAB and CRAB groups. Conclusion: Adrenal involvement and inflammatory reactions are seen in E. coli sepsis and in CRAB sepsis. These findings will be focused on in future clinical trials.

Current infection prevention and control strategies of COVID-19 in hospitals

Background/aim: Coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), has been appeared first in China since December 2019. Transmission of SARS-CoV-2 occurs primarily with droplets through coughing and sneezing and also occurs through inhalation of aerosolized secretions, which travel, remain suspended in the air longer. Materials and methods: Since early stages of the outbreak, COVID-19 cases have been described in healthcare workers (HCWs). However, in the early stages, the disease may be asymptomatic. This may lead to incorrect diagnosis or delayed diagnosis and may lead to the nosocomial spread of the virus. One of the most important causes of transmission among HCWs is being exposed to an aerosolized virus in a closed environment for a long time. It is possible to prevent and control the spread of COVID-19 in hospitals with outpatient treatment and triage. Results: Infection control measures, including wearing surgical masks, hand hygiene, and social distance are considered essential in preventing human-to-human transmissions of SARS-CoV-2. Immediate response and practices of infection control measures are critical for saving lives during an epidemic inside and outside the hospital. Conclusion: Analyzing current knowledge about the features of SARS-CoV-2 infection, screening, personal protection protocols, triage and psychological support practices for healthcare professionals can be promising in terms of controlling the infection.

Investigation of double-carbapenem efficiency in experimental sepsis of colistin-resistant Klebsiella pneumoniae.

OBJECTIVE: Klebsiella pneumoniae, a Gram-negative pathogen, especially which produces carbapenemase, is seen as a major threat to public health due to rapid plasmid-mediated spread of resistance and limited therapeutic options available for treatment. Although colistin has been recognized as a "last resort" antimicrobial for multidrug-resistant K. pneumoniae infections, these isolates have developed resistance to colistin as a result of its intensive use. The aim of this study was to evaluate the efficacy of double-carbapenem treatment of colistin-resistant K. pneumoniae experimental sepsis in mice. METHODS: In the study, 8-10-week-old Balb-c mice were divided as control groups (positive and negative) and treatment groups (colistin, ertapenem+meropenem, and ertapenem+meropenem+colistin). Sepsis was developed in mice by an intraperitoneal injection of colistin resistant K. pneumoniae. Antibiotics were given intraperitoneally 3 h after bacterial inoculation. Mice in each subgroup were sacrificed with overdose anesthetic at the end of 24-48 h and cultures were made from the heart, lung, liver, and spleen. Furthermore, homogenates of lung and liver were used to detect the number of colony-forming units per gram. Bacterial clearance was evaluated in lung and liver at different time points. RESULTS: When the quantitative bacterial loads in the lung and liver tissues are evaluated, no statistically significant difference was observed between different antibiotic treatments (p>0.05). All three treatment options were not effective, especially in 24 h. Only the decrease in bacterial load at the 48th h of the group treated with ertapenem + meropenem + colistin was found significant (p<0.05) compared to the 24 h. CONCLUSION: In the light of these data, it was understood that double-carbapenem application was not sufficient in the treatment of experimental sepsis in mice with colistin-resistant K. pneumoniae. Furthermore, ertapenem + meropenem + colistin combined therapy was not found to be superior to colistin monotherapy or double-carbapenem therapy.

Seroprevalence of coronavirus disease 2019 (COVID-19) among health care workers from three pandemic hospitals of Turkey.

COVID-19 is a global threat with an increasing number of infections. Research on IgG seroprevalence among health care workers (HCWs) is needed to re-evaluate health policies. This study was performed in three pandemic hospitals in Istanbul and Kocaeli. Different clusters of HCWs were screened for SARS-CoV-2 infection. Seropositivity rate among participants was evaluated by chemiluminescent microparticle immunoassay. We recruited 813 non-infected and 119 PCR-confirmed infected HCWs. Of the previously undiagnosed HCWs, 22 (2.7%) were seropositive. Seropositivity rates were highest for cleaning staff (6%), physicians (4%), nurses (2.2%) and radiology technicians (1%). Non-pandemic clinic (6.4%) and ICU (4.3%) had the highest prevalence. HCWs in "high risk" group had similar seropositivity rate with "no risk" group (2.9 vs 3.5 p = 0.7). These findings might lead to the re-evaluation of infection control and transmission dynamics in hospitals.

Human anthrax in Turkey: A ten years' experience (2009-2018).

Anthrax is a notifiable disease in Turkey. In order to control the human disease, animal foci are being monitored and prevention and control activities are being implemented by the Ministry of Health in coordination with the Ministry of Agriculture and Forestry. The objective of our study was to evaluate the national surveillance data and control activities in the last decade. A total of 1174 anthrax cases and 9 deaths have been reported. Anthrax was frequent in eastern provinces and in big cities where large animal movements were significant. The incidence rate was 1.5 times higher in males than in females. The disease was more common in the 30-64 age group. The number of cases increased in the summer and autumn seasons. Human anthrax is still being reported though in decreasing numbers in Turkey. A collaborative control programme continues to be needed.

Risk prediction for candidemia in surgical intensive care unit patients.

OBJECTIVE: Patients in surgical intensive care units are thought to be at the highest risk for developing candidemia, especially patients undergoing abdominal surgery. The present study aims to investigate risk factors for candidemia in patients with abdominal surgery. METHODS: A retrospective study was undertaken that involved patients admitted to the surgical ICU between January 2016 and January 2017. All postoperative adult patients (>18 years old) who underwent abdominal surgery were included in this study. RESULTS: During the one-year study period, 49 patients developed candidemia. Thirty-five of candida isolates were non-albicans strains. Of them, 25 (51%) isolates were Candida parapsilosis, eight (16.3%) isolates were C. glabrata, one (2%) isolate was C. tropicalis and one (2%) isolate was C. kefyr. The median age of all patients enrolled in this study was 60.5±15.6 years. In univariate analysis, the duration of the hospital stays, intensive care unit stay, type of surgery, respiratory failure, total parenteral nutrition, transfusion and use of central venous catheter were significantly higher in patients with candidemia. In multivariate analysis, duration of hospital and intensive care unit stay and use of central venous catheter was associated with an increased risk of candidemia. The mortality rate of case patients was 36.7%. CONCLUSION: Patients undergoing abdominal surgery are at increased risk of candidemia, especially the patients with prolonged intensive care unit/hospital stay and the patients with a central venous catheters. Antifungal prophylaxis may be considered for patients with increased risk.

Vector-borne Zoonotic Diseases in Turkey: Rising Threats on Public Health

Vector-borne zoonotic diseases (VBZDs) are a major problem for public health and animal welfare all over the world. In recent years, there has been an alarming increase in VBZDs, mainly caused by new or re-emerging arboviruses, bacteria and parasites. The World Health Organization enumerated 10 threats to global health for 2019, notably emphasizing climate change and emerging pathogens as growing priorities. It is important to review potential threats and develop new control programs for rising threats against human health and safety. Changes in host and vector population diversity and density may affect pathogen transmission patterns and influence VBZD emergence processes. In addition to environmental and climate-related changes, human and animal migratory patterns pose future threats. The geographic location and habitat features of Turkey support the establishment of many arthropod species as vectors of various diseases. To date, a total of 107 zoonotic infections have been reported originating from Turkey. Arthropods transmit 19 of 107 such infections, including 2 mosquito-borne, 9 tick-borne, 1 sandfly-borne, 3 flea-borne, 1 simuliid-borne, 1 mite-borne and 2 fly-borne diseases. In this review, we focus on the present status of knowledge on VBZDs as a rising threat to public health in Turkey to provide a foundation for future control efforts.

The efficacy of mesenchymal stem cell therapy in experimental sepsis induced by carbapenem-resistant K. pneumoniae in neutropenic mice model.

Especially in recent years, the intensive use of antibiotics has caused multiple drug resistance in Klebsiella pneumoniae. In the absence of a new antibiotic, alternative treatment options have emerged. The aim of this study was to investigate the efficacy of mesenchymal stem cell (MSC) treatment of carbapenem-resistant K. pneumoniae sepsis in neutropenic murine model. BALB-c mice were divided into two groups as control (positive and negative) and treatment groups (colistin, colistin + MSC, MSC) after the development of neutropenia with cyclophosphamide. Sepsis was developed in mice by intraperitoneal injection of carbapenem-resistant K. pneumoniae. Three hours after inoculation of the bacteria, colistin and MSC were given in the treatment groups intraperitoneally. Colistin injection was repeated every 12 h, while MSC was administered as 2nd dose after 48 h. Mice were sacrificed at 48 and 96 h. The right lung and half of the liver were quantitatively cultured, and the bacterial load was calculated as cfu/g. The left lung, the other half of the liver tissue, and both kidneys were evaluated histopathologically. IL-6 and TNF-α cytokine levels in mouse sera were determined by ELISA. Bacterial loads in lung and liver tissues of neutropenic mice were lower in the MSC + colistin-treated group at 48 and 96 h compared to colistin and MSC monotherapy groups. Also, bacterial eradication was started the earliest in MSC + colistin group. It was concluded that combining colistin with MSC provided improved therapeutic effects compared to colistin or MSC monotherapy.

Toxin-neutralizing antibodies elicited by naturally acquired cutaneous anthrax are elevated following severe disease and appear to target conformational epitopes.

Understanding immune responses to native antigens in response to natural infections can lead to improved approaches to vaccination. This study sought to characterize the humoral immune response to anthrax toxin components, capsule and spore antigens in individuals (n = 46) from the Kayseri and Malatya regions of Turkey who had recovered from mild or severe forms of cutaneous anthrax infection, compared to regional healthy controls (n = 20). IgG antibodies to each toxin component, the poly-γ-D-glutamic acid capsule, the Bacillus collagen-like protein of anthracis (BclA) spore antigen, and the spore carbohydrate anthrose, were detected in the cases, with anthrax toxin neutralization and responses to Protective Antigen (PA) and Lethal Factor (LF) being higher following severe forms of the disease. Significant correlative relationships among responses to PA, LF, Edema Factor (EF) and capsule were observed among the cases. Though some regional control sera exhibited binding to a subset of the tested antigens, these samples did not neutralize anthrax toxins and lacked correlative relationships among antigen binding specificities observed in the cases. Comparison of serum binding to overlapping decapeptides covering the entire length of PA, LF and EF proteins in 26 cases compared to 8 regional controls revealed that anthrax toxin-neutralizing antibody responses elicited following natural cutaneous anthrax infection are directed to conformational epitopes. These studies support the concept of vaccination approaches that preserve conformational epitopes.

Human anthrax in Kyrgyz Republic: Epidemiology and clinical features.

BACKGROUND: Bacillus anthracis infects both humans and animals which leads to anthrax disease. The disease is still a global issue as it occurs naturally and has a potential use for bioterrorism/bio-weapons agents. This study aimed to investigate the clinical and epidemiologic features of human anthrax that has been seen in Kyrgyzstan. METHODS: This study was carried out at the Osh Regional Hospital that is located in the southern regions of Kyrgyz Republic. Medical records of patient's diagnosed with cutaneous anthrax between 2005 and 2015 were reviewed. Epidemiology and clinical features of the infection and the effectiveness of antibiotic therapy were investigated. RESULTS: Two hundred thirty four anthrax cases were reviewed. Among the patients, men in the 31-50 age group prevailed. Infection episodes that sought medical attention occurred mostly during the summer and autumn. Analysis of epidemiological data shows that anthrax contamination occurred as a result of direct contact with mainly farm animals, slaughtering, butchering and the selling of the meat. Cutaneous lesions were localized mostly in the upper extremities. Among the observed patients, a majority of the cases presented a mild form of the disease. The isolated strains of B. anthracis were mostly susceptible to amoxiclav, ofloxacin, 3rd generation of cephalosporins, doxycycline, ciprofloxacin, rifampicin, penicillin and streptomycin. A majority of the isolates were found to be resistant to ampicillin, gentamicin, chloramphenicol. CONCLUSION: Anthrax is still an endemic disease that has lead to outbreaks in the Kyrgyz Republic. The transmission of human infection is seen by direct contact with ill animals or dead animal products. The common form seen in the clinical setting is cutaneous anthrax. Future studies should focus on the surveillance and infection control measurements associated with the anthrax.

Epidemiological features of tularaemia in Central Anatolia, Turkey.

Tularaemia has become a public health threat in Turkey. Our aim was to examine the epidemiological characteristics of 154 tularaemia cases reported from Kayseri, Central Anatolia, between 2010 and 2017. Clinical diagnosis was confirmed by micro-agglutination test (≥1/160 titres). Most patients (56.5%) were residing in rural areas. The year with the highest case load was 2011 (40% of all cases). Tularaemia was reported in all seasons, but mostly in February (26.1%). Morbidity rates were higher in women and people aged ≥65 years. The tularaemia incidence in Kayseri was higher than in the whole country between 2011 and 2016, though after the initial outbreak between 2010 and 2012, it seems to have become less frequent.
