Recently, the world's problem has become in the spread of microbes and the extent of their impact on public health, especially the problem of urinary tract infections (UTIs). Therefore, the purpose of the study was to clarify the extent of infection of the urinary tract and the extent of development of these microbes in resistance to antibiotics (antibiotic susceptibility pattern). The pathogens are isolated from hospitals and private medical centers. In this study, two hundred twenty-five urine samples were collected from various sources, where 126 patients were infected with bacteria while 99 patients had no infection. In Gram-negative bacteria, the most common bacteria were E. coli (55.5%) followed by Klebsiella spp (23.0%), Proteus spp (7.14%), Pseudomonas spp (6.34%), and Acinetobacter spp (3.96%). In the Gram-positive bacteria Staphylococcus spp (2.38%) and Enterococcus spp (1.58%) were found. Antibiotic susceptibilities for Gram-negative and positive bacteria were investigated according to clinical laboratory standard institute(CLSI 2019). In Gram-negative bacteria, Amikcin, Impinem, and levofloxacin were sensitive. However, in Gram-positive bacteria, levofloxacin, ofloxacin, and linezolid were sensitive. At the same time, most of the remaining antibiotics are 100% resistant to pathogenic-bacterial isolates. This study showed bacteria that are isolated from urine which causing urinary tract infection and showed resistance to almost all antibiotics, so UTI is difficult to treat by common antibiotics.

Urinary Tract Infection (UTI) is one of the significant healthcare and hygienic-based diseases ravaging millions of people, especially in third world countries with poor hospital settings. This cross-sectional and laboratory investigation was done to determine the incidence of nosocomial urinary tract infections (NUTIs) and antibiotic susceptibility pattern of the uropathogenic bacterial isolates from hospital patients in Nsukka, Southeastern Nigeria. Urine specimens of fifty patients were collected and analyzed between May and June 2018. Kirby-Bauer disk diffusion method was used for detection of antibiotic susceptibility pattern for all isolates. Bacteriuria was observed in urine specimens of 31 (62%) out of the 50 participants, with the specimens of 13 yielding significant growth at 42% rate of nosocomial urinary tract infections (NUTIs). The most predominant bacterial isolate of urinary tract infection was Staphylococcus spp. (31%); followed by Escherichia, Klebsiella and Proteus with (23%) each. Isolates were mostly susceptible to Ciprofloxacin (87.1%), while other isolates were mainly resistant to Zinnacef (937%). Pertinent recommendations were made with respect to treatment, multidrug resistance mitigation and aseptic and optimal health services delivery practices.

Abstract Background: Urinary tract infection is one of the most common bacterial infections in children. Understanding the characteristics of uropathogens and their antimicrobial susceptibility pattern in a particular setting can provide evidence for the appropriate management of cases. This study aimed to assess the bacterial profile of urinary tract infection, their antimicrobial susceptibility pattern and associated factors among clinically suspected children attending at Felege-Hiwot Comprehensive Specialized Hospital, Northwest Ethiopia.Methods: A hospital-based cross-sectional study was conducted from February-April, 2019. A systematic sampling technique was employed. A mid-stream urine sample was inoculated on cystine lactose electrolyte deficient media and incubated for 24-48 hours. Sub-culturing was done on Mac-Conkey and blood agar. Antimicrobial susceptibility test was done on Muller-Hinton agar. A binary logistic regression model was used to see the association between dependent and independent factors. A p-value<0.05 at 95% CI was considered as statistically significant.Results: The overall prevalence of urinary tract infection was 16.7% (95% CI 12.4-21.1). Both Gram-negative and Gram-positive bacterial isolates were recovered with a rate of 44/50 (88%) and 6/50 (12%) respectively. Among Gram-negative isolates, E. coli 28/44(63.6%) was predominant while S. saprophyticus 2/6(33.3%) was prevalent among Gram-positive bacterial isolates. Overall, a high level of resistance to ampicillin, augmentin, and tetracycline was shown by Gram-negative bacteria with a rate of 44/44(100%), 39/44(88.6%), and36/44 (81.8%) respectively. About 33/50(66%) of overall multidrug resistance was observed (95% CI 52-78). About six Gram-negative bacterial isolates were extended spectrum beta-lactamase (ESBL) producers. Having a history of urinary tract infection (P-0.003, AOR 1.86-22.15) and male uncircumcision (p-0.00, AOR 5.5-65.35) were the independent variables that associate for urinary tract infections.Conclusion: In the present study, the prevalence of urinary tract infection among children was high and considerably a high proportion of multidrug resistance was observed. This result will have a significant impact on the selection of appropriate antimicrobial agents for the treatment of urinary tract infection.

Objective: This work aimed to detect the antibiotic susceptibility pattern of Escherichia coli isolated from children, as it is the most predominant pathogen of urinary tract infection (UTI). Methods: About 530 urine samples were collected and tested using the modified Kirby–Bauer disk diffusion method to find the susceptibility pattern of isolated bacteria. Results: Out of a total of 530 samples, 114 (21.50%) showed significant growth. A total of 8 different types of bacteria were isolated from the growth of positive samples. Among the isolates, E. coli 66 (57.8%) was found to be the most predominant organism followed by Klebsiella pneumoniae 18(15.8%), Proteus spp. 10 (8.8%), Staphylococcus aureus 8 (7.0%), Acinetobacter spp. 4 (3.5%), CoNS 4 (3.5%), Enterobacter spp. 2 (1.8%), and Pseudomonas aeruginosa 2 (1.8%). In the present study, out of 66 E. coli, 37 (56.1%) were multidrug-resistant strain. E. coli showed 94.0% resistance to ceftriaxone followed by ceftazidime 86.5% and cefotaxime 70.3%. Imipenem (91.9%) followed by amikacin (89.2%) seems to be the effective drug against UTI causing E. coli in children. Conclusion: Multidrug resistance may possess difficulties with the choice of therapeutic options for the treatment of severe infections.
