Background. Regardless of the global concerted effort to control the development and spread of antimicrobial resistance, increasing cases are continually documented at many medical centres. This situation is reinforced by inadequate information on the trend of resistance resulting from lack of regular antimicrobial resistance surveillance. The present study sought to detect the number of multidrug-resistant (MDR), extended drug-resistant (XDR), and pandrug-resistant (PDR) bacterial isolates at a health facility in Ghana from January 2018 to July 2020. Method. A total of 800 data on antimicrobial testing results were extracted from the records of the health facility. The extracted data were explored for the detection of MDR, XDR, and PDR. The study further determined the use of antibiotics using the multiple-drug resistance index (MDRI). Results. Except for Staphylococcus and Neisseria spp., all bacterial isolates showed extremely high (100%) proportion of MDR. Although only Staphylococcus spp. (38 (4.8%)) was observed to be XDR, the rest of the bacteria showed the potential to attain the status of XDR or PDR. MDRI indicated high use of antibiotics in the health facility. Conclusion. The high antimicrobial resistance observed by the study underscores the need for prompt and effective antibiotic resistance control strategies.

Background: The present study was undertaken to study the percentage of pathogenic bacteria present in different fruit and vegetable samples available in the market in and around Kalaburagi, Karnataka, South India. Methods: A total of 940 different samples were collected from Kalaburagi, out of which 390 (23.84%) were fruits and 550 (35.27%) were vegetables. The pathogenic bacteria were isolated, by enrichment culture method using peptone water. The bacterial isolates were identified by convention microbial identification procedures. Result: Antibiotic resistant testing by disc diffusion method performed for E.coli, Salmonella and Shigella. Among the pathogens, E. coli (86.50%) of the isolates were resistant to Nalidixic acid while Imipenem and Trimethoprim-Sulfamethoxazole has the lowest resistance (19.84%), Salmonella (86.66%) isolates were resistant to Ciprofloxacin while Norfloxacin has the lowest resistance (4.76%) and Shigella (80.35%) isolates were resistant to Vancomycin while Amoxicillin has the lowest resistant (3.57%). Multiple drug resistance (MDR) was seen in E. coli at (38.88%), Salmonella at (26.66%) and Shigella at (10.71%) accordingly. The study therefore shown that E.coli, Salmonella and Shigella occur in Fruits and vegetables which collected from market place in Kalaburagi, Karnataka India, As per the results, adequate precaution should be taken while handles these fruits and vegetables. The antimicrobial resistance pattern shown by the isolates is an indication that adequate measurement needs to be taken to regulate the drug use in both humans and animals in order to minimize the risk of increasing antimicrobial resistance.

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.

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.

Salmonellosis caused by non-typhoidal Salmonellaenterica from poultry products is a major public health concern worldwide. This study aimed at estimating the pathogenicity and antimicrobial resistance in S. enterica isolates obtained from poultry birds and their food products from different areas of Pakistan. In total, 95/370 (25.67%) samples from poultry droppings, organs, eggs, and meat were positive for Salmonella. The isolates were further identified through multiplex PCR (mPCR) as Salmonella Typhimurium 14 (14.7%), Salmonella Enteritidis 12 (12.6%), and other Salmonella spp. 69 (72.6%). The phenotypic virulence properties of 95 Salmonella isolates exhibited swimming and/or swarming motility 95 (100%), DNA degrading activity 93 (97.8%), hemolytic activity 92 (96.8%), lipase activity 87 (91.6%), and protease activity 86 (90.5%). The sopE virulence gene known for conferring zoonotic potential was detected in S. Typhimurium (92.8%), S. Enteritidis (100%), and other Salmonella spp. (69.5%). The isolates were further tested against 23 antibiotics (from 10 different antimicrobial groups) and were found resistant against fifteen to twenty-one antibiotics. All isolates showed multiple drug resistance and were found to exhibit a high multiple antibiotic-resistant (MAR) index of 0.62 to 0.91. The strong biofilm formation at 37 °C reflected their potential adherence to intestinal surfaces. There was a significant correlation between antimicrobial resistance and the biofilm formation potential of isolates. The resistance determinant genes found among the isolated strains were blaTEM-1 (59.3%), blaOxA-1 (18%), blaPSE-1 (9.5%), blaCMY-2 (43%), and ampC (8.3%). The detection of zoonotic potential MDR Salmonella in poultry and its associated food products carrying cephalosporin and quinolone resistance genes presents a major threat to the poultry industry and public health.

The objective was to gather information on the status of antimicrobial surveillance in the Asia Pacific region and suggest control strategies. Twenty-one economies of the Asia Pacific region participated in this initiative. A survey was conducted on antimicrobial use and surveillance throughout the region. A workshop was carried out to create awareness about the issue and discuss the implementation of control strategies. Based on the survey results and workshop conclusions, it can be established that there is better understanding of the implications of antimicrobial resistance in the human medicine area. Only few economies take actions to control antimicrobial resistance on a veterinary/agricultural level. To confront antimicrobial resistance, it is critical to raise awareness; cooperation between all countries is needed to apply international standards, to be able to have harmonized public policies. Countries must align and improve their systems for surveillance and monitoring of antimicrobial resistance in human, animals, and the environment.

Abstract Background: The emergence of multi-drug resistant Citrobacter freundii poses daunting challenges to the treatment of clinical infections. The purpose of this study was to characterize the genome of a C. freundii strain with an IncX3 plasmid encoding both the blaNDM-1 and blaSHV-12 genes.Methods: Strain ZT01-0079 was isolated from a clinical urine sample. The Vitek2 system was used for identification and antimicrobial susceptibility testing. The presence of blaNDM-1 was detected by PCR and sequencing. Conjugation experiments and Southern blotting were performed to determine the transferability of the blaNDM-1- carrying plasmid. Nanopore and Illumina sequencing were performed to better understand the genomic characteristics of the strain.Results: Strain ZT01-0079 was identified as C. freundii, and the coexistence of blaNDM-1 and multiple drug resistance genes was confirmed. Electrophoresis and Southern blotting showed that blaNDM-1 was located on a ~53kb IncX3 plasmid. The NDM-1-encoding plasmid was successfully transferred at a frequency of 1.68×10−3. Both blaNDM-1 and blaSHV-12 were located on the self-transferable IncX3 plasmid.Conclusion: The rapid spread of the IncX3 plasmid highlights the importance of continuous monitoring of the prevalence of NDM-1-encoding Enterobacteriaceae. Mutations of existing carbapenem resistance genes will bring formidable challenges to clinical treatment.

Antimicrobial resistance (AMR) in Salmonella in poultry poses a serious human health threat as it has zoonotic importance. Poultry is often linked with outbreaks of Salmonella-associated foodborne illness. Since antimicrobials are heavily used in poultry in Bangladesh, multidrug-resistant (MDR) Salmonella is quite frequently found there. MDR Salmonella is challenging to treat with antimicrobials and often causes a severe economic loss in the poultry sector. By horizontal gene transfer and/or evolutionary mutations, antimicrobials primarily exert selection pressure that contributes to antimicrobials resistance. In addition, resistance patterns can vary with variations in time and space. Without having prior knowledge of resistance patterns, no effective drugs could be prescribed. Therefore, it is crucial to have updated knowledge on the status of AMR in Salmonella in Bangladesh for effective treatment and management of the flocks against salmonellosis. There are several review articles on AMR in Salmonella in poultry in Bangladesh; they lack the whole scenario of the country and particularly do not have enough data on the poultry environment. Considering this scenario, in this review, we have focused on AMR in Salmonella in poultry in Bangladesh (2011–2021), with particular emphasis on data from the poultry and farm environments on a divisional zone basis.

Background: Mastitis, the inflammation of parenchyma of mammary gland is frequently considered to be costliest and complex disease prevalent in India. Mastitis is caused by pathogens like Staphylococcus spp., Streptococcus spp., Mycoplasma bovis, E. coli, Klebsiella spp., Citrobacter spp., Enterobacter spp. and Entercoccus. The treatment of mastitis in animals is carried out using antibiotics. Treatment failure in mastitis is due to increased antibiotic resistance of mastitis pathogens and also due to indiscriminate use of antibiotics without testing in vitro antibiotic sensitivity test against causal organisms. In comparison to cultural method, PCR assays takes less time for detection of bacteria from the mastitis milk samples. Present research work was carried out regarding isolation, identification and multiple drug resistance profile of clinical bovine mastitis associated pathogens using conventional as well as molecular approach. Methods: In the present study, 73 mastitis milk samples were collected from Anand and Panchmahal district of Gujarat. The milk samples were subjected for cultural isolation and DNA extraction for identification of bacteria by cultural and PCR method. Antimicrobial sensitivity pattern of the isolates were carried by disc diffusion method and isolates were categorized in multiple drug resistant. Result: In the present study, Out of 73 mastitis milk samples collected from cows 48 (65.75%) cows were positive for bacterial isolation and S. aureus was the most predominant bacterial species. PCR from the mastitis milk additionally detected bacteria in culturally negative milk samples. Most sensitive drug was gentamicin and most of the isolates (90.19%) showed the multiple drug resistance for the two to nine drugs with 0.1 to 0.6 multiple antibiotic resistance index.
