Streptococcus agalactiae serotype distribution and its antibiotic susceptibility affect disease prevention strategies, but the serotype distribution varies among patient groups. The objectives of this study were to establish the group B Streptococcus (GBS) serotype distribution in patients from Egypt and to assess antibiotic sensitivity of invasive GBS isolates. A total of 490 patients participated in this multicenter study; 160 had urinary tract infection, 115 complained of diabetic foot ulcers, 125 men had genital tract infections, and 30 women females had genital tract infections. Others had bronchopneumonia, otitis media, synovitis, or meningitis. Serotyping of the isolated GBS was performed at the CDC in the United States. Antibiotic sensitivity patterns were determined using the disk diffusion method. In men, the most common serotypes were II, III, and V, whereas types Ia, II, III, and V were isolated from women. Macrolides (erythromycin) resistance occurred in 4.1% of the isolates; 10.2% were resistant to both clindamycin and inducible resistance of macrolides, lincomycin, and streptogramin; 17.3% were resistant to quinolones; and 95.9% were resistant to tetracyclines. GBS primarily infected the urinary tract, skin, soft tissue, and genital tract in both genders. Isolates were sensitive to beta-lactam drugs, vancomycin, and linezolid; 14.0% were resistant to macrolides with or without clindamycin. Only 6.0% of the strains were sensitive to tetracyclines. Although GBS causes invasive infections in Egyptian adults, it rarely causes neonatal meningitis or sepsis. Future studies should determine whether GBS isolates are transmitted sexually, by performing a follow-up study of the partner of the infected patient.

Urinary tract infections (UTI) are one of the most common infections in the community and hospitals. Uropathogens colonize the urinary tract and may ascend to bladder causing cystitis, if left untreated reach kidneys through ureters can be responsible for acute pyelonephritis and cause renal damage. The aim of the present study is to determine the prevalence of urinary tract infections and antibiotic susceptibility pattern in a tertiary care hospital.This is an observational study conducted in Microbiology department, Hind Institute of Medical Sciences, Barabanki.A total of 623 urine(mid-stream) samples were collected from indoor and outdoor departments of hospital and culture was done on UTI chromogenic agar using semiquantitative method. Antibiotic sensitivity test was performed using Kirby Bauer disc diffusion method.Prevalence of urinary tract infections is 29% in the study. (43%) is the most common micro-organism isolated followed by (13%), (11%), (10.4%), (8.8%), (3.3%), (1.6%), CONS & (1.1%) and (6.6%). The females(56.6%) are more commonly affected than males.In the present study, beta-lactamase inhibitors and aminoglycosides were effective drugs against gram negative bacteria. Vancomycin and linezolid were sensitive in gram positive bacteria. Nitrofurantoin is the promising drug in cases of uncomplicated UTI, and safe to use in pregnancy. High recurrence rates and antimicrobial resistance are responsible for increasing the burden of disease. It is advised to use the antibiotics judiciously as per the hospital antibiotic policy which will help prevent multidrug resistance micro-organism further reducing morbidity and mortality.

Diabetic patients are associated with a higher risk of infection. The research purposed to identify antibiotic susceptibility patterns among diabetic outpatients with urinary tract infection in Pontianak. An experimental study was performed for 13 bacterial isolates of diabetic outpatients with urinary tract infection in the Clinic of Diabetes Mellitus, Sultan Syarif Mohamad Alkadrie Hospital, Pontianak. The disc diffusion method was used to perform the susceptibility of antibiotics to the bacterial isolates. Among 13 isolates, the most common causative agent of urinary tract infection was Escherichia coli (53.85%), followed by Pseudomonas aeruginosa (30.77%). Klebsiella spp and Enterobacter aerogenes were 7.69%. Most isolates of bacteria of the study had a high sensitivity to Cefepime (92.31%), then followed by Levofloxacin, Amikacin, and Meropenem for 84.62%. The study revealed low sensitivity of bacteria to Amoxicillin/Clavulanate, Co-Trimoxazole, Cefazoline and Ceftriaxone (30.77%, 23.08 %, 23.08%, 23.08%, respectively). All bacterial isolates had high resistance to Ampicillin. Moreover, multidrug resistance observed among bacterial isolates. Keywords: antibiotic susceptibility, diabetes, urinary tract infections

Background:Urinary tract infection is the most common bacterial infections in humans and serious health problem in many parts of the world. It has become more complicated in treatment due to different pathogens and increasing resistant to antimicrobial agents. This study aims to investigate the prevalence of urinary tract infection and antibiotic susceptibility patterns of pathogens among the patients attending in B & B hospital Nepal.Materials and Methods:A hospital based cross sectional study was conducted in between April 2010 to March 2011. Urine samples were collected from clinically suspected patients and tested bacteriologically using standard procedures. Antimicrobial susceptibility test was performed for isolated pathogen using the Kirby-Bauer disk diffusion method according to Clinical and Laboratory Standards Institute guidelines.Results:Out of 1260 examined specimens 25.24 % were positive and majority 61.64% were females.  The most common pathogens isolated were Escherichia coli (66.67%), Enterococcus (7.55%) and Staphylococcus (6.60 %). The drug resistant among the positive cases were reported. The highest resistant of positive cases was found with Cefexime (87.88%) and Enterococcus with Ampicillin (66.67%) and Staphyllococcus with Cloxacillin (66.67%). The highest susceptibility was for Vancomycin and Ampicillin i.e. 33.33% in each.Conclusion:The findings showed that E. coli isolates were the predominant pathogen and the presence of bacterial isolates with very high resistance to the commonly prescribed drugs. As drug resistance among bacterial pathogens is an evolving process and serious issue. Therefore, routine surveillance and monitoring studies should be conducted to provide physicians knowledge on the updated and most effective empirical treatment of UTIs. Asian Journal of Medical Sciences Vol.7(5) 2016 47-51

Background and objective: Urinary tract infections (UTIs) are the neglected infection in children from the side of study its clinical symptoms, causative organisms and their antibiotic sensitivity. This investigation searches for determine clinical symptoms frequency, prevalence rate, bacterial features, and  antibiotic sensitivity of bacterial urinary tract infection in children attending private children’s health center in Sana’a city. Methods: In a prospective study carried out over a 24-month period, 1925 samples from children patients suspected of having a UTI were investigated, of which 175 were culture-positive. Clinical and demographic data were collected. Isolated bacteria were identified by standard tests, and antibiotic susceptibility was performed by the disk diffusion method. Results: Fever was the most frequent symptom that occurred (88%) while other UTI symptoms were less frequent than that reported in adult patients for UTI. The most common etiological agent was Escherichia coli (89.7%), followed Staphylococcus aureus (3.4%), Klebsiella spp (2.9%), Proteus spp (2.3%), and beta haemolytic streptococci (1.7%).  Results of antimicrobial resistant for E. coli, as the most prevalent cause of UTI, to commonly used antibiotics are ranged from less than 3% for  levofloxacin, gentamicin,  amikacin and cefoxitin to more than 75% for  tetracycline, nalidixic acid,  doxycycline,  co-trimoxazol and amoxicillin . Conclusions: The results show the most common  symptom of UTI are fever and lack of more obvious symptoms of UTI in adult patients. The antimicrobial resistance patterns of the causes of UTI are highly changeable and constant surveillance of trends in resistance patterns of uropathogens among children  is essential.                   Peer Review History: Received: 11 July 2021; Revised: 13 August; Accepted: 5 September, Available online: 15 September 2021 Academic Editor:  Ahmad Najib, Universitas Muslim Indonesia, Makassar, Indonesia, [email protected] UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system.

Background: Urinary Tract Infection (UTI) is a common contagion among men and women with the incidence relatively higher among women due to their differing anatomy. An understanding of the kind of pathogens implicated in urinary tract infections as well as antibiotic susceptibility profiling may help the clinician make rationally correct empirical choice in their treatment. Objective: This study is aimed at determining the type and antibiotic susceptibility pattern of bacterial uropathogens isolated from female patients attending Chukwuemeka Odumegwu Ojukwu University Teaching Hospital (COOUTH), Awka, Nigeria. Method: Two hundred and forty patients with clinically diagnosed UTI and who were on at least 5 days’ antibiotic holiday were recruited into the study. Their demographic characteristics were captured using pre-tested questionnaire. Their clean catch mid-stream urine samples were collected using sterile universal container and sent to the Microbiology Department for processing. Within 30 minutes of samples collection, the specimens were cultured and the isolates were identified, after 24 h of incubation, using standard microbiological techniques. Antibiotic susceptibility tests were done with standard antibiotic discs using the Kirby–bauer disc diffusion method. Results: Out of the 240 urine samples, 89.17% yielded significant bacteriuria. The pathogens implicated were Escherichia coli (28.5%), Staphylococcus aureus (28.0%), Salmonella spp (22.8%) and Pseudomonas aeruginosa (20.5%). HIV status, patients age, pregnancy status and marital status all significantly affected bacteriuria rate (p value < 0.05), while patients’ location (sub-urban/rural dwelling), and level of education did not (p value > 0.05). The pattern of microbial resistance to antibiotics suggests that ceftazidime, fosfomycin and cefoxitin may not be used as first-line agents in the empirical treatment of UTIs rather; levofloxacin, meropenem or aztreonam should be considered. Levofloxacin was significantly effective against all the isolates and may be administered empirically while waiting for the culture result (Mean % susceptibility was 79.85). Conclusion: E. coli and S. aureus were the predominant pathogens in the study and many were resistant to the commonly prescribed antibiotics and so leave the clinicians with only few alternative drugs for UTIs treatment. Routine surveillance and monitoring studies need to be constantly conducted to update clinicians on the prevalent pathogens and the rational and empirical treatment of UTIs. Aggressive and consistent health education using every possible media is also recommended to combat the menace of drug resistance occasioned by inappropriate antibiotic use.

Introduction. Community-acquired urinary tract infections (CAUTIs) are usually treated empirically. Geographical variations in etiologic agents and their antibiotic sensitivity patterns are common. Knowledge of antibiotic resistance trends is important for improving evidence-based recommendations for empirical treatment of UTIs. Our aim was to determine the major bacterial etiologies of CAUTIs and their antibiotic resistance patterns in a cosmopolitan area of Cameroon for comparison with prescription practices of local physicians.Methods. We performed a cross-sectional descriptive study at two main hospitals in Yaoundé, collecting a clean-catch mid-stream urine sample from 92 patients having a clinical diagnosis of UTI. The empirical antibiotherapy was noted, and identification of bacterial species was done on CLED agar; antibiotic susceptibility testing was performed using the Kirby-Bauer disc diffusion method.Results. A total of 55 patients had samples positive for a UTI. Ciprofloxacin and amoxicillin/clavulanic acid were the most empirically prescribed antibiotics (30.9% and 23.6%, resp.); bacterial isolates showed high prevalence of resistance to both compounds.Escherichia coli(50.9%) was the most common pathogen, followed byKlebsiella pneumoniae(16.4%). Prevalence of resistance for ciprofloxacin was higher compared to newer quinolones.Conclusions.E. coliandK. pneumoniaewere the predominant bacterial etiologies; the prevalence of resistance to commonly prescribed antibiotics was high.

SUMMARYOne hundred and sixty-eight strains ofEscherichia coliisolated from 84 men and 84 women who had urinary tract infections (134 cases) or bacteremia of urinary tract origin (34 cases) were assessed for their carboxylesterase B electrophoretic types B and B α-haemolysin production, the presence of mannose resistant haemagglutinin (MRHA) and antibiotic susceptibility. Electrophoretic type B was phenotypically linked with α-haemolysin and MRHA productions. The strains isolated from males were more frequently of type B, haemolytic and both haemolytic and haemagglutinating than those isolated from females. The strains isolated during bacteremia were more frequently haemolytic and haemag glutinating than those obtained from urinary tract infections. Type B strains were more frequently resistant to antimicrobial agents than type B strains. The results reinforced the distinction, in terms of virulence and antibiotic sensitivity, between B and B strains and demonstrated the influence of the sex of patients on the host-parasite interaction during urinary tract infections.

In this study, a hundred Klebsiella pneumoniae strains isolated from urinary tract infections were evaluated in terms of genotyping, susceptibility to certain antibiotics and detection of extended spectrum of beta lactamase (ESBL) production. The random amplified polymorphic DNA (RAPD-PCR) method was used to identify the genetic differentiation of K. pneumoniae isolates. A total of 26 different DNA bands ranging between 334 bp and 28033 bp were detected among the strains. It was found that 100 K. pneumoniae strains revealed 11 different RAPD profiles. Antibiotic susceptibility tests were conducted using a disc diffusion method against 16 antibiotics. Fifty-five different resistance profiles were determined among the strains. ESBL-productions of the strains were determined by the double disc synergy test (DDST) and ESBL E-test methods. ESBL production rates among the strains were found to be 55% by E-test method and 45% by DDST method. While ESBL-producing K. pneumoniae strains showed the greatest resistance to penicillin G (100%), followed by piperacillin (92.7%) and erythromycin (85.4%),the resistance rates of non ESBLproducing strains to those antibiotics were determined as 97.8%, 88.8% and 88.8%, respectively. Both groups of strains showed the highest sensitivity to meropenem. Based on the results obtained from the study, it was concluded that the detection of ESBL-producing strains by the E-test method was more sensitive than by the DDST method. Phenotypic and genotypic identification methods should be used together to detect ESBL presence. The RAPD-PCR method alone will not be adequate in the genotyping of the strains and alternative DNA-based methods should be used.

Urinary tract infection (UTI) is one of the most common diseases encountered worldwide and is a major public health problem in terms of morbidity and financial costs. A cross-sectional study was conducted in Alka Hospital, Lalitpur, Nepal from February to July, 2014. A total of 353 midstream urine samples were collected from postmenopausal women visiting Alka Hospital, Lalitpur, Nepal. The samples were examined by microscopically and culture methods. The isolated organisms were identified by conventional microbiological methods. Antibiotic susceptibility test was performed by modified Kirby-Bauer disc diffusion method according to CLSI (2011) guidelines. Among 353 urine samples processed, 32 % (113) showed significant bacteriuria. Out of 113 bacterial isolates, the prevalence of gram negative bacteria was 97.3% (110) while that of gram positive was 2.7% (3). The most predominating organisms causing UTI were Escherichia coli (84.9%) followed by Klebsiella pneumoniae (5.3%), Enterococcus faecalis (1.7%), Providencia spp. (1.7%), Klebsiella oxytoca (1.7%), Proteus mirabilis (1.7%), Proteus vulgaris (0.9%), Citrobacter freundii (0.9%) and Staphylococcus aureus (0.9%). Antibiotic susceptibility tests of the isolates showed that, most of the gram negative bacterial isolates were sensitive to Piperacillin+Tazobactam followed by Amikacin, Imipenem and Nitrofurantoin, while they were resistant to Amoxicillin. All gram positive isolates were sensitive to Amoxicillin and resistant to Gentamycin. This study showed that higher aged postmenopausal women (>80 years) were at higher risk for UTI than those of lower aged ones (<80 years).
