Objective: Continuous emergence of resistance among Pseudomonas aeruginosa strains to common antimicrobial drugs have been documented world-wide. This study investigated the recent trend of antimicrobial resistance patterns of P. aeruginosa among the patients in mid & far western region of Nepal. Materials and Methods: The study was conducted on 917 patients with suspected P. aeruginosa infections, attending outpatient and inpatient departments of Nepalgunj Medical College and teaching Hospital, Banke, Nepal from September 2011 to January 2014. Specimens were collected from pus/wound, sputum, urine, tracheal aspirates, central venous catheter tip, broncho-alveolar lavage fluid, catheters and vaginal swabs and processed for isolation and identification of P. aeruginosa following the standard microbiological methods. The disc diffusion test was used to determined antimicrobial resistance patterns of the recovered isolates at the central Laboratory of Microbiology. Results: One hundred ninety four isolates were identified as P. aeruginosa. Resistance to Chloramphenicol (74.23%), Ceftriaxone (69.56%), Cefepime (57.22%), Cefoperazone-Salbactum (54.12%) and Co-trimoxazole (53.02%) was observed. All the isolates were susceptible to Imipenem. 48 (24.74%) of P. aeruginosa isolates were multi-drug resistant to >3 classes of antibiotics. Among 194 isolates, 88 (45.36%) were from the patients of 21-40 years age group, which was statistically significant (P<0.05) compared to the other age groups. Conclusions: The study revealed the presence of drug resistant strains of P. aeruginosa in Nepal. High levels of antibiotic resistance of many of the isolates might be due to antibiotic abuse. Therefore, we recommend judicious use of antibiotics by the physicians to curb the increasing multi-drug resistance of P. aeruginosa strains in Nepal.

This study was carried out in selected poultry farms to determine the prevalence, distribution and antimicrobial resistance patterns in Salmonella serovars in Ogun State, South-western Nigeria. A total of 200 faecal samples were aseptically collected from the four geographical zones of Ogun State, Nigeria. Seventy-eight Salmonella isolates spread across 39 serovars and representing a prevalence of 39% was recovered. Salmonella Urbana (n=7), Salmonella Kingston (n=6) and Salmonella Agama (n=5) serovars were more commonly isolated. Resistance was most common to ciprofloxacin (29.5%; n=23/78). Multi-drug resistance (MDR) was observed in 15.4% (n=12/78) of the isolates spread across 7 serovars: S. Kentucky, S. Telelkebir, S. Virchow, S. Blockley, S. Chomedey, S. Haifa, and S. Isangi. The study showed the diversity of Salmonella serovars and the increasing trend of antimicrobial resistance in poultry farms in Ogun State, Southwestern Nigeria.

OBJECTIVE: To determine antimicrobial resistance patterns and prevalence of multi- (MDR, i.e., resistant to 3 classes of antimicrobial agents) and extensively (XDR, i.e., resistant to 3, susceptible to 2 groups of antibiotics) drug-resistant strains of Pseudomonas aeruginosa.METHODS: This was a cross-sectional study conducted in Nepal Mediciti Hospital, Lalitpur, Nepal, using standard microbiological methods with Kirby Bauer disc diffusion to identify antimicrobial susceptibility.RESULTS: P. aeruginosa (n = 447) were most frequently isolated in respiratory (n = 203, 45.4%) and urinary samples (n = 120, 26.8%). AWaRe Access antibiotics showed 25–30% resistance, Watch antibiotics 30–55%. Susceptibility to AWaRe Reserve antibiotics remains high; however, 32.8% were resistant to aztreonam. Overall, 190 (42.5%) were MDR and 99 (22.1%) XDR (first Nepali report) based on mainly non-respiratory samples. The majority of infected patients were >40 years (n = 229, 63.2%) or inpatients (n = 181, 50.0%); 36 (15.2%) had an unfavourable outcome, including death (n = 25, 10.5%). Our larger study showed a failure of improvement over eight previous studies covering 10 years.CONCLUSION: Antibiotic resistance in P. aeruginosa occurred to all 19 AWaRe group antibiotics tested. Vulnerable patients are at significant risk from such resistant strains, with a high death rate. Sustainable and acceptable antibiotic surveillance and control are urgently needed across Nepal, as antimicrobial resistance has deteriorated over the last decade.

Abstract Background The discovery of mcr-1-positive Escherichia coli (MCRPEC), a notable superbug, attracted great attention worldwide. Swine-origin multi-drug resistance MCRPEC is a potential threat to public health and safety. To date, few detailed studies regarding swine-origin MCRPEC in Guangxi, South China, have been reported. Results In this study, thirty-three MCRPEC harbored mcr-1 genes were identified from 142 E. coli strains isolated from swine droppings and entrails in Guangxi in 2018. All MCRPEC isolates were assigned to 8 unique STs, including ST10, ST224 and ST410, which overlapped with the human-origin MCRPEC. Additionally, a total of six plasmid replicon types (IncFI, IncHI1, IncY, IncN, IncI1 and IncX1) were found. Moreover, the drug susceptibility of the MCRPEC isolates was tested with 27 antimicrobial agents belonging to 17 antimicrobial categories that are usually used in hospitals. There were 19 extended spectrum beta lactamase (ESBL) E. coli and 12 carbapenem resistant E. coli among the 33 MCRPEC strains. Importantly, the MCRPEC showed a high rate of resistance against two broad-spectrum carbapenem antibiotics, imipenem and meropenem, which are forbidden in livestock production use. Three MCRPEC strains were further identified to be extensively drug-resistant (XDR), and other isolates were recognized as multi-drug-resistant (MDR). Meanwhile, to detect whether plasmid-carrying antimicrobial resistance genes coexisted with the mcr-1 gene in the MCRPEC isolates, a total of 22 plasmid-carrying antimicrobial resistance genes were tested for. The results showed that four ESBL genes and one pAmpC gene were identified. Eight of the MCRPEC isolates also contained the carbapenem gene blaNDM-5, which could cause untreatable infections. Moreover, ten non-lactamase genes were also detected. Conclusion This study indicated that swine-origin MCRPEC isolated in Guangxi seemed to have a high rate of resistance to both regular and final line of defense drugs as well as drug resistance genes, which pose a great threat to human public safety and health.

Abstract Intensive usage of antimicrobials in the management of animal diseases leads to selection for resistance among microorganisms. This study aimed to assess antimicrobial use and to describe factors associated with the transmission of antimicrobial resistance between humans and animals in pastoralist communities of Kasese district. A mixed-methods approach was employed in this study. Rectal swabs were collected from the participants and cattle and transported in Carry–Blaire transport medium to the laboratory within 24 h of collection for culture and sensitivity to confirm carriage of multi-drug resistant bacteria. In-depth interviews were conducted among veterinary officers, veterinary drug vendors, human health facility in-charges in both public and private health facilities, and operators of human pharmacies and drug shops. Carriage of multi-drug resistant bacteria among humans was 88 (93%) and 76(80%) among cattle. Consumption of lakeshore water and carriage of multi-drug resistant bacteria in cattle were associated with carriage of multi-drug resistant bacteria in the human population. The prevalence of multi-drug resistance among organisms Isolated from both humans and animals was high. There is a high likelihood of transmission of multi-drug resistance between humans and animals.

Background: Resistance of S. typhi to a number of antibiotics has become a serious public health problem. Drug resistant S. typhi has been reported as early as 1972 in Mexico and been observed in other countries like Bangladesh, Thailand, Vietnam, Korea, Peru and India. Methods: This cross-sectional descriptive study was carried out in Ibn Sina Microbiology laboratory, Sylhet during the period from May 2012 to September 2013 to determine the antimicrobial resistance patterns of Salmonella typhi (Salmonella enterica serovar Typhi) isolated by stool culture from clinically suspected typhoid fever patients. Stool samples were collected in clean widemouthed plastic container from 249 patients, who attended Ibn Sina Hospital, irrespective of age. The specimens were cultured on Salmonella-Shigella agar (SSA), MacConkey agar (MAC) and Xylose-Lysine-Deoxycholate (XLD) Agar media. Laboratory isolation and identification of Salmonella typhi (S.typhi) were done using standard morphological and biochemical methods. Isolates identified as S typhi were differentiated from other Salmonella species using Triple Sugar Iron (TSI) agar. Antimicrobial resistance of each isolate was determined by the Modified Kirby-Bauer disc diffusion method on Muller Hinton agar using commercially available discs following Clinical and Laboratory Standards Institute (CLSI) guidelines. The panel of antimicrobials included were amikacin (30?g), azithromycin (15?g), cefixime (5?g), ceftriaxone (30?g), ciprofloxacin (5?g), chloramphenicol (30?), co-trimoxazole (1.25/23.75?g), imipenem (10?g), levofloxacin (5?g) and tetracycline (30?g). Result: Out of 249 stool specimens investigated, only 35(14.06%) isolates of S.typhi were recovered. Among 35 positive samples 19(54.29%) were adult and 16(46.71%) were children. Antimicrobial susceptibility test showed that the resistance rates of S.typhi were 97.14% for cotrimoxazole, 95.29% for azithromycin, 91.43% for cefixime, 85.71% for tetracycline, 77.14% for ciprofloxacin and 68.57 % for ceftriaxone, respectively. Increased sensitivity was reported for imipenem (88.57%), amikacin (77.14%), chloramphenicol (65.71%) and levofloxacin (42.86%). Conclusion: Of the 35 isolates of S. typhi, none was susceptible to all of the antibiotics. We therefore face the imminent prospect of encountering untreatable typhoid fever in the near future due to multi-drug resistance pattern of isolates observed in this study. Further studies with large number of specimens are highly recommended to validate the present study and to monitor microbial trends and antimicrobial resistance patterns in other parts of Bangladesh.

AbstractThe proliferation of extended spectrum beta-lactamase (ESBL) producing Pseudomonas aeruginosa represent a major public health threat. In this study, we evaluated the antimicrobial resistance patterns of P. aeruginosa strains and characterized the ESBLs and Metallo- β-lactamases (MBL) produced. Strains of P. aeruginosa cultured from patients who attended Nelson Mandela Academic Hospital and other clinics in the four district municipalities of the Eastern Cape between August 2017 and May 2019 were identified; antimicrobial susceptibility testing was carried out against thirteen clinically relevant antibiotics using the BioMérieux VITEK 2 and confirmed by Beckman autoSCAN-4 System. Real-time PCR was done using Roche Light Cycler 2.0 to detect the presence of ESBLs; blaSHV, blaTEM and blaCTX-M genes; and MBLs; blaIMP, blaVIM. Strains of P. aeruginosa demonstrated resistance to wide-ranging clinically relevant antibiotics including piperacillin (64.2%), followed by aztreonam (57.8%), cefepime (51.5%), ceftazidime (51.0%), piperacillin/tazobactam (50.5%), and imipenem (46.6%). A total of 75 (36.8%) multidrug-resistant (MDR) strains were observed of the total pool of isolates. The blaTEM, blaSHV and blaCTX-M was detected in 79.3%, 69.5% and 31.7% isolates (n = 82), respectively. The blaIMP was detected in 1.25% while no blaVIM was detected in any of the strains tested. The study showed a high rate of MDR P. aeruginosa in our setting. The vast majority of these resistant strains carried blaTEM and blaSHV genes. Continuous monitoring of antimicrobial resistance and strict compliance towards infection prevention and control practices are the best defence against spread of MDR P. aeruginosa.

SUMMARYThis study is a part of the surveillance study on childhood diarrhoea in the Andaman and Nicobar Islands; here we report the drug resistance pattern of recent isolates ofShigellaspp. (2006–2011) obtained as part of that study and compare it with that ofShigellaisolates obtained earlier during 2000–2005. During 2006–2011, stool samples from paediatric diarrhoea patients were collected and processed for isolation and identification ofShigellaspp. Susceptibility to 22 antimicrobial drugs was tested and minimum inhibitory concentrations were determined for third-generation cephalosporins, quinolones, amoxicillin-clavulanic acid combinations and gentamicin. A wide spectrum of antibiotic resistance was observed in theShigellastrains obtained during 2006–2011. The proportions of resistant strains showed an increase from 2000–2005 to 2006–2011 in 20/22 antibiotics tested. The number of drug resistance patterns increased from 13 in 2000–2005 to 43 in 2006–2011. Resistance to newer generation fluoroquinolones, third-generation cephalosporins and augmentin, which was not observed during 2000–2005, appeared during 2006–2011. The frequency of resistance inShigellaisolates has increased substantially between 2000–2006 and 2006–2011, with a wide spectrum of resistance. At present, the option for antimicrobial therapy in shigellosis in Andaman is limited to a small number of drugs.

Background and objectives: At the present time, antimicrobial resistance (AMR) is a major public health hazard, with antimicrobial resistance bacteria increasing exponentially. This study estimates the epidemiological profiles and antimicrobial resistance of Gram-positive bacteria (GPB) and Gram-negative bacteria (GNB)  isolated from clinical samples among patients admitted to two University hospitals in Sana'a city for one year (2019). Methods: This was a retrospective study of clinical samples of patients collected from January 1, 2019 to December 30, 2019. All samples were appraised to determine presence of infectious agents using standard methods for isolation and identification of bacteria and yeasts from clinical samples of patients admitted to Al-Gumhouri University Hospital and Al-Kuwait University Hospital in Sana'a city. Antibiotic resistance was done using Kirby-Bauer disc diffusion methods. Results:  2,931 different pathogenic bacteria were detected from 24,690 different clinical specimens. The samples had an overall detection rate of 11.9% (2931/24,690). Among the bacterial pathogens isolated from clinical samples, 52.4% (n=1536) had GPB and 41.2% (n=1207) had GNB. The predominant GNB isolates were E.coli (22.04%), Klebsiella spp (6.03%), Pseudomonas aeruginosa (7.1%), Acinetobacter baumannii (1.46%), Enterobacter spp. (1.09%), Citrobacter spp. (1.16%), respectively. Among the GPB, S.aureus was the most common (26.3%), Coagulase-negative Staphylococcus (8.1%), Non-hemolytic Streptococcus (9.1%), Other alpha-hemolytic Streptococcus (3.9%), Streptococcus pyogenes (1.9%), and Streptococcus pneumoniae (0.5% ). A high rate of antibiotic resistance was recorded for sulfamethoxazole/trimethoprim (85.5%), ceftazidime (81.07%), ampicillin (70.4%), cefuroxime (66.4%). Conclusions:  The current study results revealed that the rate of resistance between GNB and GPB is associated with the incidence of different infections in patients attending two major tertiary hospitals in Sana'a city is very high. These results indicate ongoing screening and follow-up programs to detect antibiotic resistance, and also suggest the development of antimicrobial stewardship programs in Sana'a, Yemen.                     Peer Review History: Received: 9 September 2021; Revised: 11 October; Accepted: 23 October, Available online: 15 November 2021 Academic Editor:  Dr. A.A.
