<strong>Introduction:</strong> Urinary tract infection is the most common infectious complication following renal transplantation and its frequency is insufficiently studied in Portugal. The aim of this study was to characterize the incidence of urinary tract infections and recurrent urinary tract infections in renal transplant recipients.<br /><strong>Material and Methods:</strong> This was a retrospective cohort observational study, obtained from clinical files of all patients who received a renal transplant at the Hospital of Santa Cruz, from January 2004 to December 2005, with a mean follow-up period of five years or until date of graft loss, death or loss of follow-up. After a descriptive analysis of the population, we used bivariate tests to identify risk factors for urinary tract infections.<br /><strong>Results:</strong> A total of 127 patients were included, with a 593 patients.year follow-up. We detected 53 patients (41.7%) presenting with at least one episode of urinary tract infection; 21 patients (16.5%) had recurrent urinary tract infection. Female gender was the only risk factor associated with the occurrence of urinary tract infections (p &lt; 0.001, OR = 7.08, RR = 2.95) and recurrent urinary tract infections (p &lt; 0.001, OR = 4.66, RR = 2.83). Escherichia coli (51.6%), Klebsiella pneumoniae (15.5%) and Enterobacter spp (9.9%) were the<br />most frequently identified pathogens. Patients did not reveal an increased mortality or allograft loss. However, urinary tract infections were the most important cause of hospital admissions.<br /><strong>Discussion:</strong> Female gender was the only risk factor for urinary tract infections in this population. Escherichia coli was the most frequent agent isolated.<br /><strong>Conclusion:</strong> Despite preventive measures, urinary tract infections remain an important cause of morbidity and hospital admissions.<br /><strong>Keywords:</strong> Urinary Tract Infections; Postoperative Complications; Risk Factors; Kidney Transplantation; Portugal.

Raoultella ornithinolytica is a bacterium that belongs to the Enterobacteriaceae family. The most frequently reported infections are gastrointestinal and hepatobiliary. Urinary tract infections are very rarely reported and bloodstream infections are usually reported without an identified source. This bacterium is responsible for an increasing number of infections, especially in immunocompromised patients. The authors describe the first case ever reported of an immunocompromised patient due to non-Hodgkin lymphoma MALT type and corticotherapy, who developed urinary tract infection and subsequently bacteriemia due to this pathogen.

Abstract Background: Urinary Tract Infection (UTI) is the most common bacterial infection in the world. E. coli is the predominant Pathogen. This study evaluates the prevalence of ESBL in E. colis isolated from patients with urinary tract infections with phenotypic and genotypic methods.Methods: This descriptive-analytical study was done on 155 isolates of E. coli isolated from patients with urinary tract infection who had received the study consent. After accurate identification of E. coli strains. ESBL production for Escherichia coli isolates which are resistant to ceftriaxone or ceftazidime was evaluated by CDT method. TEM, SHV and CTX-M genes were identified by PCR.Results: The results showed that 30 strains from 155 strains of E. coli had ESBL. Strains of ESBL producer were more in males was lower in educated persons. 38.9% of ESBL producer had antibiotic use, 29.9% -producing Escherichia hospitalization and 31.6% uti history. The highest level of drug allergy in the ESBL was related to nitrofurantoin, and the highest resistance was related to cefazolin, co-trimoxazole. The CTX-M and the CTX-M15 gene were found in 92.7% and 57.1% of cases, respectively; also the SHV and TEM genes were not found in any of ESBL-producing Escherichia coli strains. Most therapeutic response in patients was related to cefexime, ciprofloxacin and nitrofurantoin 27.4%, 26% 21.9%, respectively.Conclusion: This study showed that the history of antibiotic use, hospitalization, uti related to increase of ESBL-producing in E. coli isolates., the CTMX-M gene is the most common gene in ESBL-producing E. coli strains.

Introduction: Urinary tract infection is one of the commonest causes of childhood morbidity. Earlydiagnosis and appropriate choice of antimicrobials is essential. Hence, this study aims to identify theprevalence of Escherichia coli in childhood urinary tract infections. Methods: This was a hospital based descriptive cross-sectional study conducted in Nobel MedicalCollege, Biratnagar over a period of one year. A total of 163 cases aged 1-15 years were included andclinical profile, laboratory reports including bacterial isolates in urine cultures and their sensitivitypatterns were documented. Results: The prevalence of Escherichia coli is 45 (53.57%) C.I. Escherichia coli was the most commonorganism isolated in bacterial cultures followed by Klebsiella 12 (14.29%), Enterococcus 10 (11.90%).Urinary tract infection was common among females with male: female ratio of 1:2.3. Fever 152(93.2%) and abdominal pain 113 (69.3%) were the most common presenting symptoms. Escherichiacoli was found most sensitive to Nitrofurantoin 43 (95.5%) followed by Ciprofloxacin 41 (91.1%) andAmikacin 40 (88.8%). Conclusions: Urinary tract infections in childhood require prompt attention and treatment to preventsignificant morbidity and mortality. From this study it can be concluded that Escherichia coli is oneof the most common isolates in urine culture and Aminoglycosides and Fluoroquinolones can beaccepted as empirical treatment regimens for childhood Urinary tract infections.

Escherichia coli (E. coli) is the most common type of pathogen that causes Urinary tract infection disease. It can be presented as a pathogenic or non-pathogenic strain and found not only in the animal but also in the human intestine. This bacterium can cause opportunistic infection when the human host comprised of thalassemia patients or changes the healthy hemostatic flora. This study aimed to analyze the presence of bacteria in thalassemia patients with urinary tract infection. A total of 303 samples were collected during the period from August 2019 to January 2020 from thalassemia patients who suffered from urinary tract infection. The results showed that there were 6.9% of patients infected with E. coli, 2.6% of patients were infected with S. aureus, 0.7% with both Proteus and Klebsiella, while 89.1% of patients had a negative sample for bacteria. Also, the incidence of urinary tract infections in females is higher than in males. Besides, its occurrence in rural areas is higher than in city residents. Moreover, among 16 antibiotics tested to sensitize bacteria to antibiotics, Imipenem showed 100% efficacy on all isolated bacteria. In contrast, Netilmicin showed 80.1% efficacy, Gentamycin 80.1%, and Amikacin 76.2%. Ampicillin, Aztreonam, Amoxicillin-Clavulanic Acid, Tetracycline, and Ticarcillin-Clavulanic Acid, did not show any effectiveness toward the bacteria while other antibiotics showed different activities. Furthermore, the isolated microbes from thalassemia patients were the highest resistance to antibiotics in comparison with other studies, and this antibiotic-resistant may be due to the weakening of the patient's immune status and frequent blood taking and the antibodies it contains.

Background: Escherichia coli is considered as one of the causes of opportunistic infections. Nowadays, due to the increase in drug resistance, the treatment of these infections has become very difficult and they are recognized as the main causes of death in hospitalized patients. Objectives: The aim of this study was to determine the prevalence of blaTEM, blaSHV, and blaCTX-M genes in E. coli strains isolated from the urinary tract infection in patients in Intensive Care Units of three different hospitals in Qom, Iran. Methods: This study was conducted in three months from October to December 2014. A total of 200 E. coli samples were taken from the patients with urinary tract infections in Intensive Care units of Qom hospital. The disc diffusion method was used to determine the susceptibility pattern of antibiotic and phenotypic confirmatory tests for screening of the expanded spectrum beta-lactamase (ESBL) isolates. The presence of blaTEM, blaSHV, and blaCTX-M genes was evaluated by the polymerase chain reaction (PCR) assay. Results: Of 200 samples, ampicillin (96%) and nitrofurantoin (19.5%) showed the highest and lowest drug resistance, respectively. A total of 156 isolates (78%) were identified as ESBLs using the phenotypic method. Moreover, 76 (38%), 90 (45%), and 123 (61.5%) isolates consisted of blaCTX-M, blaSHV, and blaTEM, respectively. Conclusions: Overall, the findings of this study showed that blaTEM was the most common gene with a frequency of 61.5% in ESBL E. coli.

Abstract Background Bacterial urinary tract infections continue to be a major health problem, responsible for a significant morbidity and mortality. Its prognosis is more severe than non-bacterial forms. The aim of this work was to study the clinical and evolutionary features of bacterial urinary tract infections caused by Escherichia coli (E.coli). Methods We conducted a retrospective study including all patients hospitalized in infectious diseases department for urinary tract infection (UTI) caused by E.coli between 2010 and 2017. Results During the study period, we enrolled 613 cases of UTI caused by E.coli, among whom 75 cases (12.2%) were bacterial. There were 47 females (62.7%). The mean age was 59 ±17 years. Thirty-three patients were aged ≥ 65 years (44%). Diabetes was noted in 38 cases (50.7%) and renal lithiasis in 14 cases (18.7%). A history of UTI was reported in 13 cases (17.3%). The most common clinical presentation was acute pyelonephritis (59 cases; 78.7%) and followed by prostatitis (8 cases; 10.6%). Renal abscess was noted in 5 cases (6.7%) and prostatic abscess in 3 cases (4%). There were 36 cases of multidrug-resistant bacteria (48%). Community-acquired UTI were noted in 70 cases (93.3%). The mean duration of treatment was 18 ± 6 days. Surgery and radiological drainage were indicated in 4 (5.3%) and 2 cases (2.7%), respectively. The outcome was favourable in 58 cases (77.3%). Complications were noted in 10 cases (13.3%) represented mainly by acute renal failure in 4 cases (5.3%). Relapse was noted in 9 cases (12%) and reinfection in 6 cases (8%). Two patients died (2.7%). Conclusion Bacterial urinary tract infections were associated to complications such as renal and prostatic abscess, requiring surgery and long duration of treatment.
