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.

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.

Background. In most hospitals of developing countries, urinary tract infections are treated empirically because of lack of culture facilities. This leads to emergence of multiresistant uropathogens. Culturing and drug susceptibility testing are essential to guide therapy. Objectives. To assess changing prevalence and resistance pattern of uropathogens to commonly used antibiotics in a two-year study period. Methods. Urine specimens were collected and cultured. Uropathogens were identified by standard methods and tested for antibiotics resistance. Data were analyzed using SPSS version 16 statistical sofware. P value < 0.05 was considered statistically significant. Results. The commonest isolates in both the previous and present studies were E. coli, Klebsiella, CoNS, S. aureus, Proteus, and Citrobacter species. Previous isolates of Enterobacteriaceae were 100% sensitive to ciprofloxacin, whereas present isolates developed 31% to 60% resistance to it. Previous isolates were less resistant to gentamycin than the present ones. Multiresistance isolates were predominant in present study than previous ones. Conclusion. E. coli was predominant in the two study periods. Present isolates were more resistant than previous ones. Some previous isolates were 100% sensitive to ciprofloxacin, whereas present isolates were increasingly resistant. Ciprofloxacin and gentamicin have been recommended for empiric treatment of urinary tract infections.

Abstract Objective Urinary tract infections (UTIs) are the most common infectious diseases, and Escherichia coli is the most common pathogen isolated from patients with UTIs. The products of sfa, afa and foc genes are important for binding of the bacterium to urinary tract epithelium. Our aim was to investigate these genes in E. colis isolated from patients with UTIS. The frequencies of the genes were determined using PCR. Biofilm formation and antibiotic resistance rates were determined using microtiter plate and disk diffusion methods, respectively. The P < 0.05 was considered statistically significant. Results The frequencies of sfa, afa and foc were 75.3%, 17.5% and 22.5%, respectively showing a significantly higher prevalence of the sfa gene. The most effective antibiotics against the E. colis were nitrofurantoin and amikacin. The highest microbial resistance rates were also observed against amoxicillin and ampicillin. Furthermore, 12.7%, 6.3%, 74.7% and 6.3% of the isolates showed strong, moderate, weak capacities and no connections to form biofilms, respectively. The expression of the sfa gene was significantly associated with forming strong biofilms. Regarding the variabilities in the characteristics of E. coli strains associated with UTIs, it seems reasonable to adjust diagnostic and therapeutic methods according to the regional microbial characteristics.

Treatment of nosocomial infections is becoming difficult due to the increasing trend of antibiotics resistance. Current knowledge on antibiotic resistance pattern is essential for appropriate therapy. We aimed to evaluate antibiotic resistance profiles in nosocomial bloodstream and urinary tract pathogens. A total of 129 blood stream and 300 urinary tract positive samples were obtained from patients referring to Besat hospital over a two-year period (2009 and 2010). Antibiotic sensitivity was ascertained using the Kirby-Bauer disk diffusion technique according to CLSI guidelines. Patient's data such as gender and age were recorded. The ratio of gram-negative to gram-positive bacteria in BSIs was 1.6 : 1. The most prevalent BSI pathogen was Coagulase-NegativeStaphylococci(CoNS). The highest resistance rate of CoNS was against penicillin (91.1%) followed by ampicillin (75.6%), and the lowest rate was against vancomycin (4.4%).Escherichia coliwas the most prevalent pathogen isolated from urinary tract infections (UTIs). Ratio of gram-negative to gram-positive bacteria was 3.2 : 1. The highest resistance rate ofE. coliisolates was against nalidixic acid (57.7%). The present study showed that CoNS andE. coliare the most common causative agents of nosocomial BSIs and UTIs, and control of infection needs to be addressed in both antibiotic prescription and general hygiene.
