Background: Analysing antibiotic susceptibility pattern of uropathogens help to overcome the therapeutic difficulties created by the rising anti-microbial resistant bacteria and guides in choosing appropriate antibiotics. Hence, we aimed at evaluating the uropathogens causing urinary tract infections and study their antibiograms.Methods: Midstream urine samples were collected, cultured and appropriate biochemical tests were performed for proper identification of urinary tract pathogens in State Referral Hospital Falkawn, Mizoram, India from 1st January to 30th June 2018.Results: The most common isolated gram-negative uropathogens were Escherichia coli (40.9%), followed by Klebsiella spp. (17.6%), Proteus spp. (10.7%) and Pseudomonas spp. (3.1%). Among gram-positive organisms Enterococcus spp. (20.1%) and Staphylococcus spp. (7.6%) were grown. Urinary tract infections were more prevalent in girls (64.8%) than boys (35.2%). High level of resistance was found to amoxycillin/ampicillin by all the organisms isolated.Conclusions: Almost all the test organisms exhibited multiple antibiotic resistance. The study identified multiple antibiotics resistance by uropathogens which were earlier used as first line of treatment of UTI in children.

Pseudomonas aeruginosa is one of the most important opportunistic pathogens responsible for various types of hospital infections. High prevalence of antibiotic resistance in P. aeruginosa strains of human clinical samples cause more severe diseases for a longer period of time. The current research was done in order to study the distribution of blaIMP-1 gene among the imipenem-resistant P. aeruginosa strains isolated from burn and urinary tract infections of hospitalized patients. Two-hundred and forty-three P. aeruginosa isolates recovered from the cases of burn and urinary tract infections of inpatients and outpatients were analysis for antibiotic resistance pattern using the disk diffusion method. Then, imipenem-resistant isolates were further analyzed for distribution of blaIMP-1 gene using the PCR. Of 243 P. aeruginosa isolates, 146 strains (60.08%) were taken from outpatients and 97 strains (39.91%) were taken from inpatients. P. aeruginosa isolates harbored the highest levels of resistance against streptomycin (100%), nalidixic acid (100%), aztreonam (100%), cotrimoxazole (95.47%), ciprofloxacin (88.47%), cefotaxime (84.36%) and gentamycin (83.95%). Inpatients had a relatively higher levels of antibiotic resistance. One-hundred and twenty-one out of 126 (96.03%) imipenem-resistant P. aeruginosa isolates harbored the blaIMP-1 gene. Inpatients also had a relatively higher prevalence of blaIMP-1 gene. High prevalence of blaIMP-1 gene and also imipenemresistant P. aeruginosa are important public health issue. Clinical laboratories should consider the detection of the blaIMP-1 gene among the P. aeruginosa isolates of clinical samples.

Analyzing antibiotic susceptibility pattern of uropathogens help to overcome the therapeutic difficulties created by the rising antimicrobial resistant bacteria and guides in choosing appropriate antibiotics. Hence, we aimed at evaluating the pathogens causing UTI and study their antibiogram. Midstream urine samples were collected, cultured and appropriate biochemical tests were performed for proper identification of urinary pathogens in BSMMU from January 2013 to December 2013. The most common isolated Gram negative uropathogens were Escherichia coli (63.93%) followed by Klebsiella pneumoniae (17.09%), other bacterial species, named Pseudomonas spp. Enterobacter Acinetobacter spp. Citrobacter spp Proteus spp. Morganella. Among Gram positive organism S. aureus S. saprophyticus S. agalectiae and Enterococci were found. Urinary tract infections were more prevalent in women than men (61.68% vs. 38.32%). High level of sensitivity was found to imipenem, amikacin, nitrofurantoin, ceftriaxone, gentamicin, cefuroxime in most of the isolates. Almost all the test organisms exhibited multiple antibiotic resistances. The high multiple antibiotics resistance identified makes it necessary for antibiotic susceptibility testing to be conducted prior to antibiotic(s) prescription.Bangladesh J Med Microbiol 2016; 10 (01): 22-26

AbstractThe prevalence of antibiotic resistance in urinary tract infections (UTIs) often renders the prescribed antimicrobial treatment ineffective, highlighting the need for personalized prediction of resistance at time of care. Here, crossing a 10-year longitudinal dataset of over 700,000 community-acquired UTIs with over 6,000,000 personally-linked records of antibiotic purchases, we show that the resistance profile of infections can be predicted based on patient-specific demographics and clinical history. Age, gender, and retirement home residence had strong, yet differential and even non-monotonic, associations with resistance to different antibiotics. Resistance profiles were also associated with the patient’s records of past urine samples and antibiotic usage, with these associations persisting for months and even longer than a year. Drug usage selected specifically for its own cognate resistance, which led indirectly, through genetic linkage, also to resistance to other, even mechanistically unrelated, drugs. Applying machine learning models, these association patterns allowed good personalized predictions of resistance, which could inform and better optimize empirical prescription of antibiotics.

Bacteriological Evaluation

Abstract Objective: To evaluate the bacteriological features in non-struvite nephrolithiasis and in its associated urinary tract infection, and to establish the relationship between the two pathologies. Methods: The non-struvite calculi from 132 patients were aseptically extracted by percutaneous nephrolithotomy (PNL). The midstream urine and calculi were bacteriologically and biochemically processed. Results: Most calculi (78%) were located to renal pelvis, associated with hydronephrosis, the biochemical composition confirming the lack of struvite and revealing the predominance of calcium oxalate. The females presented significantly more colonized calculi (50%) than males (21.9%), with higher bacteriological diversity. There is a significant relation between the presence of colonized calculi and urinary tract infections, 24.2% of calculi and 25.8% of the urine samples presenting positive cultures. In 70.4% of cases, we found the same antibiotic resistance pattern between the pathogens isolated from calculi and urine, thus considering them identical strains. The Enterobacteriaceae represented the most predominant bacteria both from calculi (62.5%) and urine (63.6%), approximatively 30% being resistant to cephalosporins and over 50% resistant to fluoroquinolones, ampicillin and tetracycline. There were 3.8% of cases in which the calculi were colonized but the urine was sterile, the bacteria being sensitive to cephalosporins that are used as prophylaxis. Conclusions: In all the cases, the same bacterial species was found both in calculi and urine, and 70.4% of them were phenotypically identical. The resistance to the second generation cephalosporins is lower than in the case of other antibiotics, which makes them the most suitable for prophylaxis in PNL.

The aim of this study was to analyze the extended spectrum β-lactamases (ESBLs) production and antibiotic susceptibility profile of urinary tract infected bacterial pathogens such as Escherichia coli and Klebsiella spp. A total of 143 Gram-negative bacteria were isolated from people suffering from urinary tract infections (UTIs) were included in this study. Among them, Escherichia coli (75%) were the predominantly isolated bacterial pathogen followed by Klebsiella oxytoca (14.6%) and K. pneumoniae (10.4%). Approximately 65% (n=93) of isolates were positive for ESBL production and E.coli was found to be the highest ESBL producer (67.6%) followed by K. oxytoca (57.1%) and K. pneumoniae (53.3%). E. coli showed high level of 86.1% resistance to cefotaxime and cefuroxime and 100% sensitive to imipenem and meropenem, whereas, K. oxytoca showed high level of 90.5% resistance to cefuroxime and 100% sensitive to amikacin, imipenem and meropenem. Similarly, K. pneumoniae showed high level of 73.3% resistance to nitrofurantoin and 93.3% sensitive to imipenem. This study reveals that majority of UTIs caused bacteria are ESBL producing multidrug-resistant bacteria and showing broad spectrum antibiotic resistance profile.
