O presente trabalho teve como objetivo determinar a prevalência de infecção urinária e da bactéria Actinomyces suis na urina de 1745 porcas gestantes da região Sul do Brasil e correlacionar essa prevalência com parâmetros físicos e químicos da urina. A prevalência de infecção urinária e de A. suis foi de 28,31% e 20,63%, respectivamente. Observou-se correlação negativa entre infecção urinária e A. suis, ou seja, as porcas que apresentaram infecção urinária tinham menor prevalência de A. suis (13,67%) do que as que não a apresentaram (23,12%). Da mesma forma, as porcas portadoras de A. suis, tinham menor prevalência de infecção urinária (17,43%) do que as não portadoras (28,62%). Apenas 3,60% das porcas examinadas eram positivas para infecção urinária e A. suis simultaneamente. A cor predominante da urina foi a amarelo claro, tanto para as porcas portadoras ou não portadoras de infecção urinária ou de A. suis. Constatou-se a presença de turbidez em 83,15% das amostras, sendo que em 96,18% das amostras turvas observou-se a presença de cristais. Finalmente, a cor, aspecto, densidade, pH e presença de cristais, foram considerados como parâmetros sem valor para o diagnóstico presuntivo de infecção urinária em porcas gestantes. Prevalence of urinary tract infections and of Actinomyces suis in urine from pregnant sows. Correlation with some urine’s physical and chemical parameters Abstract A survey has been carried out in urine samples from 1745 pregnant sows from Southern Brazil, in regard to the prevalence of urinary infections and of Actinomyces suis and its correlation with some of the urine physical and chemical parameters. Prevalence of urinary infections was of 28.31% and that of A. suis, 20.63%. However, a negative correlation has been found between the incidence of urinary infection and the presence of A. suis, the prevalence of the latter being lower in sows which are positive for urinary infections (13.67%) than in those without urinary infection (23.12%). At the same time, sows positive for A. suis display a lesser number of urinary infection (17.43%) than those negative for the bacteria (28.62%). Only in 3.60% of the sows, urinary infection and A. suis occurred simultaneously. Due to the presence of crystals, turbidity was frequently observed in sow’s urine (83.15%). Crystals were present in 96.18% of sow’s turbid urine samples. Furthermore, color, turbidity, density, pH and the presence of crystals were not considered of value for the presumptive diagnosis of urinary tract infections in pregnant sows.

Factors increasing the risk of urinary tract infections in old age include reduced T lymphocyte regulation, decreased B lymphocyte antibody synthesis, impaired killer T cell function and slowed neutrophil chemotaxis. More practical causes for a high incidence of urinary infections are multiple pathology and poor nutrition. In women, a low oestrogen level increases the intravaginal pH, resulting in the lactobacillus being replaced by a pathogenic agent. Faecal stasis may also increase the risk of a urinary infection. The presentation and severity of a urinary infection are affected by intercurrent disorders such as diabetes mellitus, poor bladder control, concurrent medication and cognitive impairment. Other relevant but less common disorders are bladder calculi and tumours. Common signs of pyouria in old age are urinary incontinence, anorexia, lethargy and confusion. The infection may even be asymptomatic and this is discussed later.

Introduction: The emergence of β-lactamases producing bacteria is a problem worldwide, with increasing importance in communityacquired infections, especially in urinary tract infections. Data regarding the use of non-carbapenem antimicrobials in these infections are scarce. The aim of this study was to analyse the treatment and outcome of urinary tract infections caused by community-acquired β-lactamase-producing bacteria in children.Material and Methods: Retrospective study performed in a level III paediatric hospital, between June 2007 and December 2017. All children with β-lactamase-producing Enterobacteriaceae identified in aseptically collected urine culture were included.Results: A total of 175 urinary infections caused by β-lactamases producing bacteria were diagnosed, 34 (19%) were community-acquired: 25 Escherichia coli (74%), 4 Klebsiella pneumoniae (12%), 4 Proteus mirabilis (12%) and 1 Proteus vulgaris (3%). In 30 (88%) cases, it was the first urinary infection. After identification of the microorganism and antimicrobial susceptibility, 33 (97%) children were re-evaluated and 24 (71%) had a repeat urine culture, which was positive in three (13%). In six (18%) cases, antibiotic treatment was modified. Four (12%) children had another UTI in the following month. In 30 (88%) children, imaging was carried out, with no nephrourological malformations detected.Discussion: In the last decade, about 20% of urinary infections caused by β-lactamase-producing Enterobacteriaceae were community-acquired with a relatively stable number of cases over the years. No nephro-urological malformations were identified in these children.Conclusion: Although the number of cases is small, the clinical and microbiological outcomes showed that most were successfully treated with non-carbapenem antibiotics, with low recurrence of new episodes of urinary tract infections.

Background: Urinary tract infections (UTIs) are one of the most common infections. For treatment of UTIs, there are limited antibiotics due to increased resistance among uropathogens. Two older antibiotics; Nitrofurantoin and Fosfomycin have become novel oral therapeutic options against uropathogens. Aim of the study was to identify UTI causing micro-organisms and evaluate in-vitro activity of nitrofurantoin and fosfomycin against most common isolated organism (E. coli).Methods: Results of urine samples culture and susceptibility testing over a period of 1 year were analysed and included in this study.Results: Micro-organisms were isolated from 568 urine samples. Most commonly isolated organism was Escherichia coli (40.50%), followed by Klebsiella spp. (20.07%) and Staphylococcus spp. (17.07%). Susceptibility of E. coli to nitrofurantoin and fosfomycin was 91.74% and 65.65% respectively. Conclusion: Good activity of nitrofurantoin and fosfomycin against E. coli indicates that these two drugs are potential therapeutic alternatives for urinary tract infections.

Background: Emergence of multi-drug resistant uropathogenic E. coli strains is an increasing problem to empirical treatment of urinary tract infections in many countries. This study investigated the magnitude of this problem in Jordan. Methods: A total of 262 E. coli isolates were recovered from urine samples of Jordanian patients which were suspected to have urinary tract infections (UTIs). All isolates were primarily identified by routine biochemical tests and tested for antimicrobial susceptibility by disc diffusion method. Fifty representative Multidrug Resistance (MDR) E. coli isolates to 3 or more antibiotic classes were tested for the presence of resistance genes of blaCTX-M- 1, 9 and 15, carbapenemase (blaIMP, blaVIM, blaNDM-1, blaOXA-48), fluoroquinolones mutated genes (parC and gyrA) and clone of ST131 type using PCR methods. Results: A total of 150/262 (57.3%) of E. coli isolates were MDR. Urine samples of hospitalized patients showed significantly more MDR isolates than outpatients. Fifty representative MDR E. coli isolates indicated the following molecular characteristics: All were positive for mutated parC gene and gyrA and for ST131 clone, and 78% were positive for genes of CTX-M-15, 76% for CTX-M-I and for 8% CTX-M-9, respectively. Additionally, all 50 MDR E. coli isolates were negative for carbapenemase genes (blaIMP, blaVIM, blaNDM-1, blaOXA-48), except of one isolate was positive for blaKPC-2 . Conclusion: This study indicates alarming high rates recovery of MDR uropathogenic E. coli from Jordanian patients associated with high rates of positive ST131 clone, fluoroquinolone resistant and important types of blaCTX-M.

Background Urinary tract infections (UTIs) are the common cause of bacterial infection. Recently UTI become more complicated and difficult to treat because of appearance of pathogen with increasing resistance to antimicrobial agents. Objective To determine the etiology of the urinary tract infections and their susceptibility to antimicrobial agents. Methods This study was carried out in Kathmandu Medical College, at department of microbiology. Total 3,460 urine samples were tested microbiologically by standard procedure. Antibiotic susceptibility test was performed for all the isolates by Kirby Bauer disc diffusion method and result was interpreted according to National Committee for Clinical Laboratory Standards (NCCLS) guide line. Results Out of 3,460 urine samples 680 (19.7%) showed the significant bacteriuria. The most common pathogens isolated were Escherichia coli 75.7% followed by Klebsiella pneumoniae 10.7%, Acinetobacter spp 5.5%, Proteus spp 3.5% and Pseudomonas aeruginosa 1.2%. Most susceptible antibiotic was Amikacin, Ceftriaxone and Ciprofloxacin for most of the isolates. E. coli which was the main isolate was found to be most susceptible to Amikacin 96.1%, Nitrofurantoin 91.3% and Gentamicin 77.7% followed by Ceftriaxone 65.8% and Ciprofloxacin 64.1%. ConclusionRegular surveillance of the resistance rate among uro-pathogens is needed to ensure the appropriate therapy of UTI.DOI: http://dx.doi.org/10.3126/kumj.v9i4.6348 Kathmandu Univ Med J 2011;9(4):295-7

Asymptomatic urinary tract infections were recovered from the urine of 40 of 100 rabbits, and identical bacteria were isolated when the rabbits were retested. Urine samples which yielded significant growths of bacteria also had pus cells. Some specimens yielded more than 2 different isolates, and staphylococci were the most frequently isolated bacteria. Oxalate and uric acid crystals were seen in 6% of the samples, particularly those with significant growths of Pseudomonas aeruginosa. No ova, parasites or fungal elements were seen in 'wet-mount' preparations and no fungi were seen when urine samples were cultured. Female rabbits showed a higher number of bacterial isolates than males. Animals with significant isolates were treated with suitable antibiotics and repeat samples yielded no growth.

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
