Objectives/Aim: Urinary tract infections (UTI) are a serious public health problem and caused by many pathogens, most often by Escherichia coli and Klebsiella pneumoniae.Aim of this study was to show the frequency and antimicrobial susceptibility pattern of E. coli and K. pneumoniae in hospital isolates, following the GLASS methodology.Methods: This is a retrospective study that was conducted in the Laboratory for Urinary Infections OU Clinical Microbiology CCUS in the period from January till December 2018.A total of 13760 urine samples were processed, using standard laboratory methods, in which significant bacteriuria was detected in 3218 (23.4%) of specimens.Results: Out of the total number of positive samples, E. coli was isolated in 1166 (36.2%) and K. pneumoniae at 341 (10.6%) patients. The presence of E. coli and K. pneumoniae isolates is dominant in females (1103/73.2%) and age group 60 and older (812/54.7%). Out of the total E. coli isolates, the ESBL strain was presented with 79 (6.8%) and K. pneumoniae with 145 (42.5%). The proportion of carbapenemase (CPE) produced by K. pneumoniae isolates was 8 (2.4%). The ESBL strain distribution analysis on clinics showed the highest prevalence of both isolates at the Clinic for Nephrology: K. pneumoniae 26/17,9%; E. coli: 12/15.4%. Isolated E. coli showed the highest resistance to ampicillin 673/1166 (57,7%), trimethoprim-sulfamethoxazole 454/1166 (38.9%) and ciprofloxacin 253/970 (26.1%), while K. pneumoniae to ciprofloxacin and trimethoprim-sulfamethoxazole with 151/285 (53.0%) and 164/341 (48.1%), respectively.Conclusions: Our study has shown that the most common cause of urinary infections in hospital settings are E. coli and K. pneumoniae. Data analysis showed that the presence of ESBL isolates was significantly higher in K. pneumoniae than E. coli. CPE isolates of K. pneumoniae were also detected.

Aims: The objective of the study was to ascertain the antimicrobial susceptibility pattern and ESBL prevalence of bacteria isolated from snacks. Place and Duration of Study: Department of Microbiology (Laboratory Unit) Michael Okpara University of Agriculture Umudike. Methodology: The snacks were mashed aseptically, serially diluted and inoculated onto nutrient agar and MacConkey agar. Isolates were identified using standard microbiological procedures. Antimicrobial susceptibility of the isolates and ESBL detection was done using disk diffusion method. ESBL production was confirmed using Double Disc Synergy Test (DDST) method following CLSI recommendations. Results: Escherichia coli, Salmonella Typhi, Staphylococcus aureus and Klebsiella pneumoniae were the bacteria isolated with Escherichia coli as the most prevalent isolate with 42% occurrence in the samples screened. There was significant difference in the sensitivity of the bacteria isolates to the different antibiotics used at P=0.05. Salmonella Typhi isolates exhibited highest resistance to an antibiotic with 86% resistance to ciprofloxacin while Klebsiella pneumoniae isolates exhibited the lowest resistance to an antibiotic with 10% resistance to cefotaxime. Among the Gram-negative bacteria, 36% of suspected ESBL producing E. coli isolates were confirmed as ESBL producers indicating the highest occurrence. Conclusion: The study confirmed the presence of bacteria in street vended snacks which exhibited high resistance to antibiotics that could be attributed to the presence of ESBL producers among the isolates.

The Common

Background: Urinary tract infection (UTI) is one of the common infections encountered by the clinicians. Though a good number of antimicrobial agents are available, still UTIs have become difficult to treat due to development of resistance by the uropathogens. So, regional data regarding the common uropathogens and their sensitivity pattern is required to guide the clinicians to start empirical therapy while managing UTIs. The purpose of the study was to identify different species of microorganisms, along with their antimicrobial susceptibility pattern, causing urinary tract infection in outpatient and indoor patients at RIMS, Ranchi, Jharkhand.Methods: Observational study was conducted using urine culture and sensitivity reports collected retrospectively from records maintained in the department of Microbiology over a period from July 2016 to Feb 2017 in tertiary care hospital.Results: UTI was more common in females (57.74%) than in males (42.26%). Among the uropathogens isolated Escherichia coli (37.41%) was found to be the predominant organism followed by Klebsiella species (32.79%), Pseudomonas species (25.86%), and gram-positive bacteria Staphylococcus aureus accounted (3.92%) of total cases. The most common isolates were E. coli showed high sensitivity to amikacin (79.24%), followed by levofloxacin (77.21%) and gentamycin (62.26%). It was found to be resistant to norfloxacin (86%), nalidixic acid (86.76%) and cefotaxime (69.88%).Conclusions: Though various microorganisms are responsible for UTI. Escherichia coli species is the most common organism. Antimicrobial resistance has already emerged against many antibiotics, making empirical treatment of these infections challenging.
