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.

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.

The bacterial and sensitivity pattern towards antimicrobials on urinary tract infections (UTI) patients are very important to beknown by clinicians to get a successful treatment. The bacterial and sensitivity pattern towards antimicrobials will be changed in differentplace and time, so that those should be analyzed routinely. To evaluate the bacterial and antimicrobials resistance pattern on urinarytract infections patients. A retrospective study on 220 urinary samples in January until December 2004 at Clinical Microbiology subunit of Dr.Wahidin Sudirohusodo hospital . Of 99 samples of UTI, Prevalence of UTI in woman (54.5%) were higher than man (45.5%).Most of sample (28 samples) were found in 0 to 15 years group. The most bacteries in urine were Escherichia coli (39.4%) and Klebsiella(26.3%). Amikacin was sensitive to all bacteries, while amoxicilin and ampicilin were resistance. Prevalence of UTI in women werehigher than in men. Incidens of UTI was highest in children group. The most bacteries in urine samples were Escherichia coli. Amikacinwas sensitive to all bacteries, while Amoxicilin and Ampicilin were resistance.

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.

Abstract Background and Aims Urinary tract infection is among the most common causes of sepsis presenting in hospitals. The aim was to collect data to enable empirical treatment of urinary tract infections in HIV negative and positive nephrology patients while waiting for urine culture results in order to reduce hospital stay. Our aim is also to assess incidence and antimicrobial susceptibility of urinary tract infections in HIV negative and positive patients. Method A retrospective chart review of nephrology patients admitted from January to December 2014 in Nephrology ward and the first consecutive 200 outpatients seen in Nephrology clinic in 2014 at Inkosi Albert Luthuli Central Hospital was conducted. Information was gathered with the use of a data collection sheet and urinary tract infection was based on urine culture results. All data was analysed using Statistical Package for Social Sciences version 23. Percentages of basic characteristics were calculated between groups. Logistic regression analysis was used to identify factors associated with positive urine culture. Results There were 654 patients in the study, 514 (79%) were HIV negative and 139 (21%) were HIV positive. The incidence of UTI in nephrology patients was 9%, 10.1% in inpatients and 6.5% in outpatients. 22% were HIV positive (p value 0.883, 95% CI 0.550-2.003). 19% had Diabetes mellitus, 15% had Systemic Lupus Erythematosus and 5% were post renal transplant patients. Escherichia coli and Klebsiella pneumonia were the common causes of urinary tract infection at 40.7% and 15.3% respectively with 22% cases on extended beta lactam resistance. Conclusion There was no statistically significant difference on the incidence and anti-microbial isolates between HIV infected and HIV negative nephrology patients with urinary tract infection. Hence, empirical treatment for UTI should remain the same in the 2 groups. Escherichia coli and Klebsiella pneumoniae were the most commonly cultured organisms in both groups. There is microbial resistance to commonly used antibiotics. Constant assessment of anti-microbial sensitivity of urinary tract infections is of paramount importance.

Introduction. Urinary tract infections are one of the most common community infections. The diagnosis of urinary infections in the elderly is complex because of its presentation and clinic. The aim of this article is to evaluate the usefulness of blood cultures in febrile urinary tract infection in elderly patients, risk factors, causes of discordance between urine and blood cultures, usefulness of biomarkers and mortality. Material and methods. Observational study of patients admitted over 65 years old, with urinary infections. Results. A total of 216 episodes with urinary infections and blood cultures performed. 70 (32,4%) cases with bacteremia. The most frequently detected isolates in blood cultures were: Escherichia coli 50 (71,4%) and Proteus spp. 6 (8,5%). Only septic shock was associated with a higher frequency of bacteraemia (OR=2,93, IC 95: 1,0-8,5; p=0,04). In 26 of the blood cultures a different isolation of the urine culture was detected. Overall mortality was 9.1%, with no association with the presence of bacteremia (p>0. 05). Conclusions. One third of elderly people hospitalized by tract urinary infection had bacteremia. Their detection was not associated with overall mortality. Disagree between blood and urine cultures in febrile is frequent, especially in patients with recent antibiotic treatment or recently hospitalized.

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.

Introduction: The aim of the current study was to investigate the prevalence of virulence genes in uropathogenic Escherichia coli (UPEC) isolates in Ilam. Materials and Methods: For this purpose, a total of 80 UPEC isolates were collected for patients with UTIs during a 6 months period. The multiplex polymerase chain reaction (multiplex PCR) was used to detect the papEF, fimH, iucD, hlyA, fyuA, and ompT genes. Results: The prevalence of fimH, papEF, iucD, fyuA, hlyA, hlyA, and ompT genes were 87.5%, 47.5%, 60%, 67.5%, 27.5%, 47.5% and 71.2%, respectively. Among all of the isolates, 27 profiles were obtained. Conclusion: Our findings demonstrated that the most prevalence was found for fimH, and different distribution of virulence genes suggested different ability of pathogenicity.
