ABSTRACT Urinary tract infections (UTI) occur commonly in dogs, and gram-negative enteric bacteria are the most prevalent pathogens. Clinical parameters, urinalysis, and urine culture and sensitivity results were retrieved from the medical records of 208 dogs with positive urine cultures over a 3 yr period at the Louisiana State University Veterinary Teaching Hospital. Several groups were defined including dogs presented for primary care versus referred cases; simple UTI, complicated UTI, and pyelonephritis; dogs pretreated with antimicrobials; and dogs having an indwelling catheter in place prior to sampling. Nearly 80% of dogs had complicated UTI. Of all dogs, 70% had no documented clinical signs of lower urinary tract disease (LUTD), with 68% of them showing hematuria and/or pyuria. Based on clinical signs or urinalysis, 19% of all dogs had no evidence of lower UTI. In dogs without LUTD signs the most common comorbidities were immunosuppressive treatment and severely restricted mobility (23%). Chronic recurring UTI were present in 19% of dogs with LUTD signs. Distribution of bacterial species was comparable with the existing literature and not significantly different between clinical subgroups. Isolates from dogs pretreated with antimicrobials showed decreased susceptibility to enrofloxacin. The prevalence of multidrug-resistant Escherichia coli and Staphylococcus spp. was moderate (29%).

Canine and feline urine culture reports and medical records were reviewed at a veterinary teaching hospital from 2006 to 2011 for enterococcal growth, coinfections, antimicrobial resistance, urine sediment findings, clinical signs, and concurrent conditions. Of all of the urine specimens with significantly defined colony-forming units/mL, Enterococcus (E.) faecalis was the only enterococci isolated from cats and predominated (77.4%) in dogs followed by E. faecium (12.9%), E. durans (3.2%), and other Enterococcus spp. (6.5%). The majority of specimens with significant enterococcal growth resulted in complicated urinary tract infections in 83.9% of dogs and 81.8% of cats. Specimens with only enterococcal growth were more common than those mixed with other bacterial species. Cocci were observed in urine sediments of 8 out of 8 cats and 21 out of 25 dogs with available concurrent urinalyses. Pyuria was noted in 5 out of 8 feline and 15 out of 25 canine urine sediments, and pyuria in dogs was associated with growth of only enterococci on aerobic urine culture. Multidrug resistance was identified in 6 out of 11 cats and 7 out of 31 dogs, and E. faecium isolates from dogs were 4.5× more likely to be multidrug resistant than E. faecalis.

ABSTRACTTo improve antibiotic prescribing, we sought to establish the probability of a resistant organism in urine culture given a previous resistant culture in a setting endemic for multidrug-resistant (MDR) organisms. We performed a retrospective analysis of inpatients with paired positive urine cultures. We focused on ciprofloxacin-resistant (cipror) Gram-negative bacteria, extended-spectrum-beta-lactamase (ESBL)-producingEnterobacteriaceae, carbapenem-resistantEnterobacteriaceae(CRE), and carbapenem-resistant nonfermenters (CRNF). Comparisons were made between the frequency of each resistance phenotype following a previous culture with the same phenotype and the overall frequency of that phenotype, and odds ratios (ORs) were calculated. We performed a regression to assess the effects of other variables on the likelihood of a repeat resistant culture. A total of 4,409 patients (52.5% women; median age, 70 years) with 19,546 paired positive urine cultures were analyzed. The frequencies of ciprorbacteria, ESBL-producingEnterobacteriaceae, CRE, and CRNF among all cultures were 47.7%, 30.6%, 1.7%, and 2.6%, respectively. ORs for repeated resistance phenotypes were 1.87, 3.19, 48.25, and 19.02 for ciprorbacteria, ESBL-producingEnterobacteriaceae, CRE, and CRNF, respectively (P< 0.001 for all). At 1 month, the frequencies of repeated resistance phenotypes were 77.4%, 66.4%, 57.1%, and 33.3% for ciprorbacteria, ESBL-producingEnterobacteriaceae, CRE, and CRNF, respectively. Increasing time between cultures and the presence of an intervening nonresistant culture significantly reduced the chances of a repeat resistant culture. Associations were statistically significant over the duration of follow-up (60 months) for CRE and for up to 6 months for all other pathogens. Knowledge of microbiology results in the six preceding months may assist with antibiotic stewardship and improve the appropriateness of empirical treatment for urinary tract infections (UTIs).

Abstract Urinary tract infections can be uncomfortable, painful and even dangerous for most dog breeds. Clinical signs are often nonspecific and insufficient for diagnosis. Urinalysis in combination with biochemical parameters and urine culture is the best combination of clinical findings for diagnosis of urinary tract infections. The incidence of urinary tract infections in dogs population is growing and 27% of dogs develop an urinary tract infection through their life. Urinary infections occur more often in the elderly than in younger dogs. More than 70% of all urinary tract infections are infections with one bacterial species. Biochemical profile is important aspect for diagnosis establishment, but due to the nature of action infection by different agents may be considered as individual case. The main aim of this research was to analyse biochemical parameters of Maltese and Belgian Shepherd (Malinois) dog breed, who were affected by urinary tract infections. Urea concentration was elevated in Malinois, while urea, phosphates, albumins and alkaline phosphatase activity were elevated in Maltese dogs. Statistical analysis showed differences in concentrations of urea, creatinine, phosphates, so as alanine aminotransferase, alkaline phosphatase and amylase activity between compared breeds during acute urinary infections. Maltese dogs are less resistant to bacterias, that causes urinary tract infections, and have lower chance to maintain homeostasis of biochemical parameters in blood during urinary bacterial infections, in comparison to Maltese dogs.

Objectives: To investigate clinical characteristics, bacterial characteristics, drug resistance status in patients with urinary tract infections treated at Department of Urology, Hue University Hospital. Materials and Method: The study was conducted in 474 patients with urological disease treated at Department of Urology, Hue Universiry Hospital from July 2017 to April 2018. Urine culture was done in the patients with urine > 25 Leu/ul who have symptoms of urinary tract disease or infection symptoms. Patients with positive urine cultures were analyzed for clinical and bacterial characteristics. Results: 187/474 (39.5%) patients had symptoms associated with urinary tract infections. 85/474 (17.9%) patients were diagnosed with urinary tract infection. The positive urine culture rate was 45.5%. Symptoms of UTI were varied, and no prominent symptoms. E. coli accounts for the highest proportion (46.67%), followed by, Staphycoccus aureus (10.67%), Pseudomonas aeruginsa (8,0%), Streptococcus faecali and Proteus (2.67%). ESBL - producing E. coli was 69.23%, ESBL producing Enterobacter spp was 33.33%. Gram-negative bacteria are susceptible to meropenem, imipenem, amikacin while gram positive are vancomycin-sensitive. Conclusions: Clinical manifestations of urinary tract infections varied and its typical symptoms are unclear. E.coli is a common bacterium (46.67%). Isolated bacteria have a high rate of resistance to some common antibiotics especially the third generation cephalosporins and quinolones. Most bacteria are resistant to multiple antibiotics at the same time. Gram (+) bacteria are susceptible to vancomycin, and gram (-) bacteria are susceptible to cefoxitin, amikacin, and carbapenem.

Urinary tract infections (UTIs) represent a serious global health issue, especially due to emerging multidrug-resistant UTI-causing bacteria. Recently, we showed that the human amniotic membrane (hAM) could be a candidate for treatments and prevention of UPEC and Staphylococcus aureus infections. However, its role against multidrug-resistant bacteria, namely methicillin-resistant S. aureus (MRSA), extended-spectrum beta-lactamases (ESBL) producing Escherichia coli and Klebsiella pneumoniae, vancomycin-resistant Enterococci (VRE), carbapenem-resistant Acinetobacter baumannii, and Pseudomonas aeruginosa has not yet been thoroughly explored. Here, we demonstrate for the first time that the hAM homogenate had antibacterial activity against 7 out of 11 tested multidrug-resistant strains, the greatest effect was on MRSA. Using novel approaches, its activity against MRSA was further evaluated in a complex microenvironment of normal and cancerous urinary bladder urothelia. Even short-term incubation in hAM homogenate significantly decreased the number of bacteria in MRSA-infected urothelial models, while it did not affect the viability, number, and ultrastructure of urothelial cells. The hAM patches had no antibacterial activity against any of the tested strains, which further exposes the importance of the hAM preparation. Our study substantially contributes to basic knowledge on the antibacterial activity of hAM and reveals its potential to be used as an antibacterial agent against multidrug-resistant bacteria.

This paper on the fluoroquinolone resistance epidemiology stratifies the data according to the different prescription patterns by either primary or tertiary caregivers and by indication. Global surveillance studies demonstrate that fluoroquinolone resistance rates increased in the past years in almost all bacterial species exceptS. pneumoniaeandH. influenzae, causing community-acquired respiratory tract infections. However, 10 to 30% of these isolates harbored first-step mutations conferring low level fluoroquinolone resistance. Fluoroquinolone resistance increased in Enterobacteriaceae causing community acquired or healthcare associated urinary tract infections and intraabdominal infections, exceeding 50% in some parts of the world, particularly in Asia. One to two-thirds of Enterobacteriaceae producing extended spectrum -lactamases were fluoroquinolone resistant too. Furthermore, fluoroquinolones select for methicillin resistance inStaphylococci.Neisseria gonorrhoeaeacquired fluoroquinolone resistance rapidly; actual resistance rates are highly variable and can be as high as almost 100%, particularly in Asia, whereas resistance rates in Europe and North America range from <10% in rural areas to >30% in established sexual networks. In general, the continued increase in fluoroquinolone resistance affects patient management and necessitates changes in some guidelines, for example, treatment of urinary tract, intra-abdominal, skin and skin structure infections, and traveller’s diarrhea, or even precludes the use in indications like sexually transmitted diseases and enteric fever.

The most widespread ailments in dogs are urinary tract infections (UTIs) caused by bacterial species. It is necessary to recognize the prevailing bacterial pathogens and their susceptibility to antimicrobial agents to effectively treat UTIs. The present study aimed to classify the bacterial organism that causes UTIs in dogs and their patterns of antimicrobial resistance. A total of 141 urine samples were collected from diseased dogs in Veterinary Clinical Complex LUVAS in Hisar, India. Culture, biochemical and sensitivity testing were performed for each of the urine samples based on standard method. Of the total 141 urine samples from dogs, 21 (14.9%) isolates were identified as Klebsiella spp. The isolates were found to be highly resistant to ampicillin (100%), penicillin G (100%), oxytetracycline (100%), enrofloxacin (85.7%), chloramphenicol (80.6%), ceftriaxone (76.2%) and cloxacillin (71.4%), while susceptibility was observed against gentamicin (100%), amikacin (100%) and neomycin (90.5%). In the current study, 19 out of 21 identified isolates were found to be multidrug-resistant. This study indicates that dogs in the study area are found to harbor highly resistant Klebsiella spp. Therefore, when deciding on the antibiotic regimen for UTIs cases, Vets should consider resistance profile of chosen antibacterial agents before usage in order to discourage dissemination of resistant organisms in the study area.
