This retrospective study tried to find the potential approach for reducing the urinary tract infection (UTI) in intensive care patients (ICPs) among adult population.In total, 96 eligible ICP cases were included. Of these, 48 cases received 10% povidone-iodine and were assigned to the intervention group, while the other 48 cases underwent sterile water, and were assigned to the control group for the prevention of catheter-associated UTI before indwelling urinary catheter insertion in ICP. The primary outcome was the occurrence of an UTI after the indwelling catheter...

Manganese (Mn) is an essential micronutrient that is not readily available to pathogens during infection due to an active host defense mechanism known as nutritional immunity. To overcome this nutrient restriction, bacteria utilize high-affinity transporters that allow them to compete with host metal-binding proteins. Despite the established role of Mn in bacterial pathogenesis, little is known about the relevance of Mn in the pathophysiology of E. faecalis. Here, we identified and characterized the major Mn acquisition systems of E...

Urinary tract infections (UTIs) caused by uropathogenic Escherichia coli (UPEC) induce cystitis, pyelonephritis, and can cause kidney scarring and failure if inflammation is not under control. The detailed effects of cytotoxic necrotizing factor 1 (CNF1), the key UPEC toxin, on the pathogenicity of UPEC remain unclear. CD36 is an important scavenger receptor, responsible for pathogen and apoptotic cell clearance, and plays an essential role in host immune defense and homeostasis. Regulation of CD36 by bacterial toxins has not been reported...

Ceftazidime-avibactam is a novel β-lactam/β-lactamase inhibitor combination for the treatment of serious infections caused by resistant Gram-negative pathogens. Population pharmacokinetic (PK) models were built to incorporate PK data from five Phase III trials in patients with complicated intra-abdominal infection, complicated urinary tract infection or nosocomial (including ventilator-associated) pneumonia. Ceftazidime and avibactam PK were well-described by two-compartment disposition models, with creatinine clearance (CrCL) the key covariate determining clearance variability...

Escherichia coli is the main etiological agent of urinary tract infections. Its virulence factors are important during the initial interaction stage with the host as they enable colonization of urinary tract tissues. The genetic markers evidencing susceptibility to develop recurrent infections have been previously described. Toll-like receptors are critical sensors of microbial attacks, and they are also effectors of the individual's innate defense for elimination of pathogens. The aim of this study was to evaluate the association between functional polymorphisms (896 A>G, 1196 C>T, - 2570 A>G, - 2081 G>A) and susceptibility to develop urinary tract infections as well as E...

New technological advances have paved the way for significant progress in automated urinalysis. Quantitative reading of urinary test strips using reflectometry has become possible, while complementary metal oxide semiconductor (CMOS) technology has enhanced analytical sensitivity and shown promise in microalbuminuria testing. Microscopy-based urine particle analysis has greatly progressed over the past decades, enabling high throughput in clinical laboratories. Urinary flow cytometry is an alternative for automated microscopy, and more thorough analysis of flow cytometric data has enabled rapid differentiation of urinary microorganisms...

Introduction: Haemophilus influenzae commonly causes upper respiratory tract infections and has only rarely been reported etiology of urinary tract infections. Since the introduction of the Haemophilus influenzae b (Hib) vaccine, non-typable haemophilus species now cause the majority of invasive disease in Europe. Case Report: We report a case of an adult man with non-typable Haemophilus influenzae septicemia, urinary tract infection and bilateral renal stone disease...

Purpose: Ureteroscopic lithotripsy (URS) is gaining popularity for the management of ureteral stones and even renal stones, with high efficacy and minimal invasiveness. Although this procedure is known to be safe and to have a low complication rate, febrile urinary tract infection (UTI) after URS is not rare. Therefore, we aimed to analyze the risk factors and causative pathogens of febrile UTI after URS. Materials and Methods: Between January 2013 and June 2015, 304 patients underwent URS for ureteral or renal stones...

BACKGROUND: In the intensive care unit (ICU), catheter-associated urinary tract infection (CAUTI) is the most common urinary tract infection. Nevertheless, there is no systematic review to investigate the epidemiology of pathogens and antimicrobial resistance of CAUTIs in ICUs. METHODS: Eight electronic databases were searched for eligible studies. A meta-analysis was performed to calculate the CAUTI incidence per 1,000 catheter days, the proportion of pathogen distribution, and the resistance rate with R3...

Extraintestinal pathogenic E. coli (ExPEC) possess the ability to cause extraintestinal infections such as urinary tract infections, neonatal meningitis and sepsis. While information is readily available describing pathogenic E. coli populations in food-producing animals, studies in companion/sports animals such as horses are limited. In addition, many antimicrobial agents used in the treatment of equine infections are also utilised in human medicine, potentially contributing to the spread of antibiotic resistance determinants among pathogenic strains...

Mycoplasma genitalium (MG) was first isolated by Tully from the urinary tract of the male patient with non-gonococcal urethritis (NGU) in 1981. MG is extremely difficult to be cultured and was rarely studied until the development and application of molecular biology technology. The research on MG in China is still in the primary stage. However, relevant studies abroad have found that it is an important pathogen causing human genitourinary tract infection and spreading worldwide. Male MG infection is reportedly related to NGU, prostatitis, epididymitis, balanoposthitis, male HIV infection, and male infertility...

Extraintestinal pathogenic Escherichia coli (ExPEC) are important human pathogens responsible for urinary tract infection and meningitis. Therefore, infection of chickens by highly pathogenic E. coli with multi-drug resistance has become a major concern to food safety. In this study, we isolated a strain of E. coli (HB2016) from the oviduct of a diseased chicken with colibacillosis. Inoculation of chickens with 2 × 106  CFU of the isolate E. coli HB2016 by intraperitoneal injection successfully reproduced colibacillosis in chickens...

Background: Extraintestinal pathogenic Escherichia coli (ExPEC) is an important bacterium and responsible for many bloodstream infections, including urinary tract infections and even fatal bacteremia. The aim of this research was to investigate whether ExPEC strains isolated from Turkish blood cultures have a relationship between 16S rRNA based phylogenetic clusters and antibiotic resistance profiles, virulence factors or clonal lineages. Methods: Phenotypically identified ExPEC blood culture isolates ( n  = 104) were included in this study...
