The increasing prevalence of foodborne diseases observed in developing countries has been linked to a rise in the consumption of raw foods. However, unlike the classical pathogens that are commonly implicated in foodborne illnesses, members of the genus Acinetobacter are rarely associated with diarrheal disease, probably because of the difficulty in isolating these Gram-negative bacteria from food sources. Nevertheless, several species of Acinetobacter, especially A. baumannii, possess many of the characteristics associated with successful pathogens and exhibit a prodigious ability to acquire the multiple-drug resistance (MDR) phenotype. In this mini-review, we summarize the epidemiological data relating to MDR Acinetobacter and consider evidence suggesting that contaminated dairy products, along with raw fruit and vegetables, constitute extra-hospital reservoirs of this underrated pathogen, and may represent an increased risk to immunocompromised individuals and young children in healthcare settings.

SUMMARYThe aim of this study was to determine the potential association between housing type and multiple drug resistance (MDR) inEscherichia coliandEnterococcus faecalisisolates recovered from 283 laying-hen flocks. In each flock, a cloacal swab from four hens was collected and produced 1102E. coliand 792E. faecalisisolates. Broth microdilution was used to test susceptibility to antimicrobials. Country and housing type interacted differently with the MDR levels of both species. In theE. colimodel, housing in a raised-floor system was associated with an increased risk of MDR compared to the conventional battery system [odds ratio (OR) 2·12, 95% confidence interval (CI) 1·13–3·97)]. In theE. faecalismodel the MDR levels were lower in free-range systems than in conventional battery cages (OR 0·51, 95% CI 0·27–0·94). In Belgium, ceftiofur-resistantE. coliisolates were more numerous than in the other countries.

Abstract Background Campylobacter species are among the most common causes of enteric bacterial infections worldwide. Men who have sex with men (MSM) are at increased risk for sexually transmitted enteric infections, including globally distributed strains of multidrug-resistant Shigella species. Methods This was a retrospective study of MSM-associated Campylobacter in Seattle, Washington and Montréal, Québec with phenotypic antimicrobial resistance profiles and whole genome sequencing (WGS). Results We report the isolation of 2 clonal lineages of multidrug-resistant Campylobacter coli from MSM in Seattle and Montréal. WGS revealed nearly identical strains obtained from the 2 regions over a 4-year period. Comparison with the National Center for Biotechnology Information’s Pathogen Detection database revealed extensive Campylobacter species clusters carrying multiple drug resistance genes that segregated with these isolates. Examination of the genetic basis of antimicrobial resistance revealed multiple macrolide resistance determinants including a novel ribosomal RNA methyltransferase situated in a CRISPR (clustered regularly interspaced short palindromic repeats) array locus in a C. coli isolate. Conclusions As previously reported for Shigella, specific multidrug-resistant strains of Campylobacter are circulating by sexual transmission in MSM populations across diverse geographic locations, suggesting a need to incorporate sexual behavior in the investigation of clusters of foodborne pathogens revealed by WGS data.

SUMMARYThe epidemiological data on shigellosis in Teknaf, a coastal area of Bangladesh, were reviewed for a 10-year period (1975–84). Certain similarities and differences were observed in the epidemiology of the disease in Teknaf when compared with urban Dhaka and rural Matlab. Similarities included: round-the-year infection with two peaks, one in the monsoon period and the other in the winter period; high male to female attendance ratio at the treatment centre: the predominance of infection in the under-15-year age group; high mortality rate in the under-5-year age group of both sexes and in females of all age groups; the multiple drug resistance of organisms. Differences included the higher isolation rate of organisms in Teknaf (42·1 % as against 11–12% in Dhaka and Matlab) and the preponderance of Shigella dysenteriae 1 infection in females in Teknaf. The unusually high isolation rate of shigella makes Teknaf the area with the highest incidence of shigellosis in Bangladesh.

Objectives - Surgical site infections (SSI) has turn out to be a major problem even in hospital with most modern facilities and standard protocols of pre -operative preparation and antibiotic prophylaxis. Objective of this study is to know the prevalence of surgical site infection among the postoperative patients and to identify the relationship between SSI and etiological pathogens along with their antimicrobial susceptibility at North Eastern Indira Gandhi Regional Institute of Health and Medical Sciences (NEIGRIHMS), Shillong. Methods - A retrospective case study conducted at NEIGRIHMS, among patients admitted to the surgical departments during the period between January 1st and December 31st 2016. Swabs from the surgical sites were collected under sterile conditions and standard bacteriological tests were performed for identification and appropriate statistical methods were employed to look for association between SSI and etiological pathogens. Results - Out of the 1284 samples included in the study, 192 samples showed evidence of SSI yielding an infection rate of 14.9%. The most commonly isolated bacteria were: Escherichia coli, Acinetobacter baumanii and Staphylococcus aureus, of the gram negative isolates 6.2% were multidrug resistant of which 19% were carbapenem resistant. Conclusion - SSI with multiple drug resistance strains and polymicrobial etiology reflects therapeutic failure. The outcome of the SSI surveillance in our hospital revealed that in order to decrease the incidence of SSI we would have to: a) incorporate a proper antibiotic stewardship  b) conduct periodic surveillance to keep a check on SSI d) educate medical staffs regarding the prevention of surgical site infection.

Tuberculosis is infectious and socially dependent disease, being now one of the most pressing issues in practical health care. As well the usual types of tuberculosis infection, chemoresistant tuberculosis is spreading rapidly in the world. The WHO estimates that about 500,000 people on the planet are infected with M. tuberculosis, which is resistant to standard anti−tuberculosis drugs. The probability of successful treatment decreases with emergence of new genotypes of M. tuberculosis with total resistance. In the modern epidemiology of tuberculosis, it is important to identify genotypes on certain signs, allowing to address issues such as their origin, identification of the infection source, possible routes and factors of transmission, as well as to reveal cases and spread of resistance to anti−tuberculosis drugs. To evaluate the therapy efficiency of multidrug−resistant tuberculosis patients with revealed genotypic variability during treatment, 10 patients with chemoresistant pulmonary tuberculosis having M. tuberculosis genotypic variability were treated. In these patients, the clinical, laboratory and radiological dynamics of disease in intensive phase of treatment were studied. Analysis of treatment results for patients with chemoresistant tuberculosis with genotypic variability of M. tuberculosis was evaluated by the intoxication syndrome dynamics of, the timing of closure of the decay cavities and cessation of bacterial excretion. The study found that the genotypic variability of M. tuberculosis is characterized by the change of less virulent genotypes of M. tuberculosis to more virulent. Signs of intoxication have been shown to change from less virulent M. tuberculosis genotypes to M. tuberculosis Beijing genotypes. Genotypic variability of mycobacteria in hospital suggests that hospitalization in tuberculosis facilities is a risk of exogenous tuberculosis superinfection. Studying the influence of genotypic variability of M. tuberculosis on the course of multidrug−resistant tuberculosis requires more extensive research, being a very relevant and promising area in phthisiology. Key words: Mycobacterium tuberculosis, genotypic variability, VNTR−genotyping, treatment.
