Background and Objectives: Urinary Tract Infection (UTI) is one of the most common infections in the community and hospitalized patients. The aim of the present study was to investigate bacteria isolated from urinary tract infections and their antibiotic resistance in hospitalized patients. Subjects and Methods In the this descriptive-cross-sectional study, the results of about 5,000 urine samples sent for culture from the hospitalized patients of Golestan Hospital in Ahvaz in 2019 were examined. Relevant information was extracted from patients’ medical records. Results Out of 5000 samples studied (39.7% female and 60.3% male), about 468 samples (9.36%) showed positive urine culture. Of the patients with UTI, 205 patients were women (43.8%). The risk of UTI increased with age. The most common bacteria caused urinary tract infections were E. coli with 51.5%, followed by Klebsiella with 29.3%. It was also observed that bacteria isolated from urine samples of people with UTI had antibiotic resistance, and for each bacteria special groups of antibiotics were more effective. Conclusion The prevalence of UTI in the studied patients was 9.36%. In females and with increasing age, the prevalence of UTI was higher. The most common bacteria that caused UTI were E. coli and then Klebsiella. Due to the fact that the resistance and sensitivity of bacteria to antibiotic used, it is recommended that the most common bacterial agents of UTI must be diagnosed and then the most appropriate antibiotic must be prescribed

Urinary tract infections are the second common reason of medical consultations and antibiotics prescription. Escherichia coli is known to cause most urinary tract infections. The aim of this study was to characterize and determine the antibiotic resistance profile of E. coli extended-spectrum βlactamases (ESBL) producer strains isolated from urine samples. The urine samples collected came from hospitalized and non-hospitalized patient referred to Hubert Koutoukou Manga (HKM), National and University Hospital Center (Cotonou, Benin). The resistance to antibiotics was determined according to the disk diffusion method. The production of penicillinase and ESBLs was researched respectively by the acidimetric test and double disk synergy method. The presences of genes encoding βlactamases were detected by Polymerase Chain Reaction (PCR). Our data revealed that 60 % of E. coli strains (101) were isolated from female patients. Also, 69.31 % of the strains were isolated from non-hospitalized patients. The high resistance levels were recorded with amoxicillin (96.04 %) and amoxicillin + clavulanic acid (66.34 %). Twenty percent (20%) of strains were ESBLs. Among ESBLs strains, 70% comes from non-hospitalized patients. Eighty percent of E. coli strains produced penicillinase among which 25 % were ESBL producers. All the ESBL producers strains carried blaTEM gene whereas only 30 % carried the blaSHV gene. This study updates the data on the prevalence to antibiotic resistance of E. coli ESBL producers strains for better management of urinary tract infections.

Abstract Objectives The prevalence of ESBL-producing Escherichia coli (ESBL-E. coli) in community-acquired urinary tract infections (UTI) has been increasing worldwide since 2000, but with large geographical variations. The aim of this study was to determine whether the ESBL-E. coli rate in urine samples from individuals with community-acquired UTI was associated with the local socio-economic, environmental, agricultural and healthcare characteristics. Methods This was a cross-sectional study in western France using data on antibiotic susceptibility of E. coli isolated from urine samples of individuals with community-acquired UTI analysed in non-hospital laboratories from 2015 to 2017. The ESBL-E. coli rate was calculated for each laboratory. Data on socio-economic characteristics, human antibiotic consumption, hospital bed density, animal farming density and percentage of agricultural land and surface water were retrieved at the municipality level and aggregated by study area. Their association with ESBL-E. coli prevalence was quantified using multivariate linear regression models with a backward selection. Results From 358 291 E. coli isolates from urine samples tested in 92 laboratories, the mean ESBL-E. coli prevalence for the study period was 3.30%. In an adjusted model, the ESBL-E. coli rate was significantly (P < 0.05) and positively associated with the local percentage of people >65 years old, third-generation cephalosporin use (DDD/1000 inhabitants), number of hospital beds/km2, poultry density, pig density and percentage of agricultural land. Lower deprivation was associated with a higher ESBL-E. coli rate. Conclusions Several anthropogenic factors (primary care, hospitals and animal farming) are associated with the local ESBL-E. coli rate in community-acquired UTI. These results could contribute to improve risk management, including identification of at-risk patient groups.

Cancer patients are at high risk of antibiotic resistant bacterial urinary tract infections (UTIs). In this study, we assessed the bacterial profile and antibiotic resistance among cancer patients suspected of UTI in B.P. Koirala Memorial Cancer Hospital in Nepal through a cross-sectional study with routinely collected data. All cancer patients who had a recorded urine culture between July 2018–June 2019 were included in the study. Out of 308 patients who had undergone culture, 73 (24%) of samples had bacterial growth. The most common organisms isolated were E. coli (58%), Staphylococcus (11%) and Klebsiella (10%). These bacteria had undergone susceptibility testing to 27 different antibiotics in various proportions. Of the limited antibiotic testing levels, nitrofurantoin (54/66, 82%) and amikacin (30/51, 59%) were the most common. Among those tested, there were high levels of resistance to antibiotics in the “Access” and “Watch” groups of antibiotics (2019 WHO classification). In the “Reserve” group, both antibiotics showed resistance (polymyxin 15%, tigecycline 8%). Multidrug resistance was seen among 89% of the positive culture samples. This calls for urgent measures to optimize the use of antibiotics in UTI care at policy and health facility levels through stewardship to prevent further augmentation of antibiotic resistance among cancer patients.

Objective: To determine the frequency of urinary tract infections and the spectrum of microorganisms causing UTI and their antibiotics susceptibility pattern in children age between 1 month and 12 years. Patients and Methods: In this cross-sectional study, 131 patients of suspected UTI, from the department of pediatric medicine were included, from June-2020 to Nov-2020. 5 milliliters of urine sample were collected and sent to the hospital laboratory for determination of UTI. If UTI was confirmed, samples were further processed to determine the pattern of organisms causing UTI and their antibiotic spectrum. Results: Mean age of the patients included in this study was 6.07±256 years. There were 75 (57.25%) male patients, and 56 (42.75%) female patients. Urinary tract infections were diagnosed in 30 (22.90%) patients. E. coli diagnosed in 14 (46.67%) patients. Resistant strains were diagnosed in 3 (10%) patients. Regarding antibiotic sensitivity, 3rd generation cephalosporins and carbapenems were sensitive to many organisms. Conclusion: E. coli is the predominant uropathogen causing UTIs in children. Third generation cephalosporins are optimal initial choice for management of UTI in children. Keywords: urinary tract infections, causating micro-organisms, antibiotic sensitivity

Tract Infections

Background: A urinary tract infection (UTIs) is a common type of infection caused by bacteria that travel up the urethra to the bladder. Globally, it is reported that 150 million people are diagnosed with a UTI annually, costing the world economy over 6 million US dollars in treatment and work loss. Studies conducted in the in-patients pediatric ward of Muhimbili Hospital in Tanzania and Mulago National Referral Hospital in Uganda between five to ten years reported the prevalence of UTI to be 16.8% and 14.6% respectively. On average at Kam Medical Consult Clinic, patients who turn up in the laboratory are about 20%, and 50% of patients present with recurring UTIs clinically. Therefore,  there is a need to establish and investigate the prevalence of bacterial pathogens associated with UTI and multiple pathogens that are not known. Methodology: The cross-sectional study was carried out at Kam medical consult clinic (KMCC) located in Kafeero zone Mulago II Kawempe division. The study population was adults and children presenting with symptoms of urinary tract infection. 120 Midstream urine Samples were collected from patients presenting clinical signs of UTI. The diagnosis was done through macroscopy dry chemistry, microscopy, and culture. Results Among the sampled population, 33% of males had urinary tract infections while 67% of females had urinary tract infections.  88.5% were outpatients while 11.5 % were in-patients The overall prevalence of UTI among patients was 63.3% with children aged (1-10) having a prevalence of 5.8 %. Conclusion and recommendation: E.coli is an etiological agent causing UTIs in male and female patients presenting UTI at Kam Medical Consult Clinic. Other etiological agents included Klebsiella, Coliform, Enterococcus species, staphylococcus aureus, pseudomonas species, and candida species. There is a need to monitor the profile of etiological bacteria of UTI through culture and sensitivity regularly.
