Background: Escherichia coli is one of the most frequent causes of many bacterial infections, including Urinary Tract Infections (UTI), blood stream infections, otitis media, pneumonia, meningitis, traveler’s diarrhoea, enteric infections and systemic infections. This study was done with the aim to surveying antibiotic sensitivity pattern of isolated Escherichia coli in both sex attended in NIMS Hospital, Jaipur under the taken time period.Methods: In this cross-sectional study, 62 Escherichia coli were isolated from various clinical specimens of the patients attending both OPD and IPD. The strains were selected using the laboratory standard methods and culture-specific. The antibiotic susceptibility testing was performed using Kirby-Bauer disk diffusion method.Results: Out of total 62 isolates of Escherichia coli 26(41.93%) isolates were from male while 36(58.064%) from female patients. Maximum sensitivity were shown by Polymyxin B and Colistin i.c 100% followed by Nitrofuratonin 82.5% followed by Meropenem 79.03%, Aztreonam 72.58%, Piperacillin/ Tazobactam and Ciprofloxacin 61.30%, each Amikacin 56.45%, Imipenem 54.83%, Ofloxacin 45.16%, Cefepime 43.54%, Ceftazidime 38.71%, Gentamycin and Ceftriaxone 37.09% each, Cefotaxime 30.64%, Norfloxacin 27.5%. Maximum resistance shown against Norfloxacin 72.5%, followed by Gentamycin and Ceftriaxone 62.90%, Ceftazidime 61.30%.Conclusions: Escherichia coli infected more in urinary tract infection as compare to other sample in human, and it is common in female than male. Regular monitoring of antimicrobial susceptibility for E.coli is recommended to improve treatment. A changing trend in antibiotic sensitivity profile of the isolates need to be monitored as there is limited availability of newer drugs and the emergence of resistant bacteria far exceeds the rate of new drug development.

Background: Urinary tract infection (UTI) is one of the most common bacterial infections encountered by clinicians particularly in developing countries. Current knowledge on antimicrobial resistance pattern is essential for appropriate therapy. The aim of the present study was to identify the causative organisms for UTI and to determine the antibiotic susceptibility pattern of organisms causing UTI. Method: This cross sectional study was carried out in the department of Microbiology, Sir Salimullah Medical College, Dhaka, from a period of January 2014 to December 2014. Results: Out of 2136 clinical sample of urine, 430 (20.1%) showed significant bacterial growth. Escherichia coli was the commonest urinary pathogen (76.3%), followed by Pseudomonas spp. (7.9%), Proteus spp. (7.2%), Klebsiella spp., Citrobacter spp. (1.9% each) and Staphylococcus aureus (1.6%). Isolated uropathogens showed highest resistance for Amoxycillin (86%-97%) and Cefradin (71%-100%), resistance rate for other commonly used antimicrobial agents was high; Cefixime (52%-85%), Ceftriaxone (50%-71%), Ciprofloxacin (50%-88%), Cotrimoxazole (50%-75%), Gentamicin (57%-75%) and Nitrofurantoin (43%-100%), while uropathogens were least resistant to Imipenem (0%-15%) and Amikacin (0%-29%). Conclusion: Due to high degree of resistance to commonly used antimicrobials to treat UTI, routine monitoring and evaluation studies should be conducted to update physicians’ knowledge about most effective antibiotics for treatment of UTI.

Background: Urinary tract infections (UTIs) remain the common infections in outpatients as well as hospitalized patients. Current knowledge on antimicrobial sensitivity pattern is essential for appropriate therapy. The aim of the study is to determine the changing pattern of antibiotic sensitivity among uropathogens causing UTI. Methods: Urinary isolates from symptomatic UTI cases attending in Square hospital were processed in the Microbiology lab. Antimicrobial susceptibility testing was performed by Kirby Bauer’s disc diffusion method. Extended spectrum beta lactamase (ESBL) production was determined by double disk synergy test method. Results: Of the 200 tested sample 110 samples showed growth of pathogens among which the most prevalent were E.coli (58.18%) followed by Enterococci (13.6%). The majority (68.18%) of the isolates were from female. ESBL production was observed in 46.87% o E.coli strains and 25% of Klebsiella strains. More than 98% of the isolates are sensitive to Imipenem, Meropenem , while 86.36% are sensitive to Amikacin, 73.63% to Nitrofurantoin and 74.54% to Gentamicin. Very high rate of resistance is seen against amoxicillin (88.19%), cefixime (65.46%), cotrimoxazole (68.19%) and ceftriaxone (63.63%). E. coli showed high sensitivity to meropenem, imipenem and amikacin (100%) followed by Gentamicin (94.1%). Conclusion: The study revealed that E.coli was the predominant bacterial pathogens of UTIs. An increasing trend in the production ESBLs among UTI pathogens in the community was noted. Nitrofurantoin should be used as empirical therapy for primary, uncomplicated UTIs.

Catheter-associated urinary tract infections (CAUTI), remains the commonest hospital-acquired infection (HAI). This emphasizes the need to implement and monitor effective infection control programs to reduce the risk of CAUTI. Aim of the present study was to determine the etiology with antibiotic susceptibility and also to calculate CAUTI rate. The Patients admitted in intensive care unit (ICU), Rajarajeshwari Medical College and Hospital who were on urinary catheter insertion for >48 hours from 1 August, 2019 to 30 September, 2019 were included in the study. Under aseptic conditions urine samples were collected from clinically suspected cases of CAUTI, the samples were processed in the department of Microbiology, as per standard protocols. Uropathogens were isolated, identified and subjected to antibiotic sensitivity test. CAUTI rate was calculated and results were noted. Among 460 patients on catheter in ICU, 28(6%) patients developed clinical signs or symptoms of UTI. Of 28 urine samples cultured, 4(14%) yielded growth of single organis [Escherichia coli (3), Klebsiella (1)] and 24(86%) showed no evidence of growth. 2300 catheter days were obtained of 460 patients on indwelling catheter in ICU. Thus CAUTI rate was 1.74 per 1000 catheter days over a 2 month period.CAUTI remained a great burden to patient safety and a challenge to the infection control team. Implementation of proper care bundles and continuous education to health care workers plays a key role in reducing the CAUTI rates, thereby decreasing the morbidity and hospital stay to the patients.

AbstractUropathogenic strains of E. coli isolated from urine of patients with urinary tract infections were tested for antibiotic sensitivity using bio-Merieux kits and ATB-UR 5 expression system. The virulence of strains was evaluated by serum bactericidal assay, macrophage “killing” and bacterial adhesive tests. Survival capability of strains was assessed under starvation in saline. The results showed that quinolone-resistant uropathogenic strains of E. coli exhibit significantly reduced adhesive potential but relatively high resistance to serum and macrophage bactericidity. In contrast to laboratory strains, the quinolone-resistant uropathogenic clinical isolate demonstrated increased viability during starvation in saline. Our study suggests that quinolone-resistant uropathogenic strains are highly adaptable clones of E. coli, which can exhibit compensatory viability potential under unfavorable conditions. The clinical occurrence of such phenotypes is likely to contribute to the survival, persistence and spread strategy of resistant bacteria.

Sensitivity Pattern

Urinary tract infection is one of the most common bacterial infections seen in clinical practice both in developed and developing countries. The causative agents of Urinary tract infection vary from place to place and they also vary in their susceptibility and resistance patterns. This descriptive study aimed to evaluate the antibiotic susceptibility patterns of pathogens isolated from routine laboratory specimens at Dhaka Medical College Hospital. A descriptive cross- sectional study was done from January 2018 to June 2018. A total of 100 mid-stream urine samples from the suspected UTI patients were tested microbiologically and antimicrobial susceptibility test were performed for the isolated pathogens using Kirby-Bauer disk diffusion method with positivity rate of UTI was 90% (90/100). Escherichia coli (39%) was the most UTI causing bacteria followed by Klebsiella 18(18%), Acinetobacter 12(12%), Staphylococci, 9 (9%), Pseudomonas 6 (6%), Enterococcus species 3 (3%) and Proteus 3 (3%). Female 83 (83%) were more affected in comparison with male. Adult female especially age range 18-30 years were found in high risk. Nitrofurantoin, Amikacin and Meropenem were recorded as most sensitive antibiogram for most of the bacteria’s whereas cephalosporin showed increased resistance. However, for uncomplicated community acquired UTI, Nitrofurantoin (oral) and Amikacin (Injectable) can be chosen as first line medication. J MEDICINE JUL 2020; 21 (2) : 93-97
