SUMMARYA group of 150Staphylococcus saprophyticusstrains isolated from urinary tract infections in women were included in this study. Antimicrobial susceptibility tests showed that these isolates were sensitive to most antimicrobial agents. All strains were sensitive to penicillin. cephalothin. gentamicin. kanamvcin. trimethoprim and nitrofurantoin. Resistance to tetracycline was present in 10·6% of the strains. to chioramphenicol in 4 % to erythromycin in 1·3% and to streptomvcin in 1·3% All strains were resistant to cadmium chloride as well as to novobioein and nalidixic acid. Plasmid analysis showed that 8·2 % of the strains harboured plasmids, some of them with complex plasmid profiles.

Background and Objectives: Our aim is to identify uropathogens that cause urinary tract infections (UTIs) that necessitate hospitalization, and analyze outcomes of gestational UTIs. Methods: This study consisted of 30 pregnant women who necessitate hospitalization because of UTI (7.8% of gestational UTIs during the same period of time). UTI that necessitates hospitalization is defined as clinical complaints, urination problems, urine analysis and culture positivity, fever and uterine discomfort. Patients with at least two positive cultures (≥ 100,000 cfu/ml) were included to this study. Antimicrobial susceptibility tests were obtained in all cases in order to determine antimicrobial resistance and to choose the ideal antibiotics for treatment. Results: In our study, we have found that Escherichia coli is the most common microorganism (56.7%). Enterococcus faecalis (13.3%) and Klebsiella pneumonia (10%) were other frequently observed microorganisms. In this series, mean gestational week at birth was 35 weeks 5 days (range 23-40 weeks). Mean birthweight was 2,656 g (range 500-3,700 g). Twenty-three cases (76.7%) were hospitalized before 37th gestational week and preterm delivery rate was 56.3%. Maternal risk factors and coexisting diseases were detected in 11 (36.7%) patients as follows: diabetes mellitus in 4, thrombophilia in 3, thyroid disorders in 3 and hydroureteronephrosis in 1 case. Cesarean section rate was 65.2%. Conclusions: Knowing uropathogens of patient population is beneficial in the management of patients and better planning of future medical treatments. Preterm labor seems to be an important complication in pregnancies with UTIs going together with fever and urination problems.

Urinary tract infections are very common among people of all ages, but the disease is more prevalent in women, so proper clinical and laboratory diagnosis, and the right treatment are very important to avoid complications and antimicrobial resistance. This study aimed to determine the bacterial causes and antibiotic susceptibility patterns of UTI patients. Recorded results of 6065 urine sample cultures and their antimicrobial susceptibility tests from the Department of Microbiology in Tobruk Medical Center, Tobruk City, were obtained from September 2016 to December 2018. The data was analyzed and discussed in compare with other studies. The study showed that a UTI is more common in females (78.8%) compared with male patients (21.2%). Gram-negative bacteria accounted for the majority of urinary pathogens (90%), where E. coli alone was (58.4%), klebsiellae (17.4%), Proteus (10.7%), while Pseudomonas species was the least common (3.3%) of the total. While the Gram-positive bacteria S. aureus constituted 9.6% of the total. The study was found statistically significant (P=0.000). The most effective antibiotics against all uropathogens were Imipenem and Amikacin, and less effective antibiotics were Ampicillin and Amoxicillin-clavulanic acid. This study concluded that the most common cause of UTI in Tobruk was Escherichia coli and the most effective antibiotics appear to be Imipenem and Amikacin.

Tract Infections

The treatment of urinary tract infections (UTIs) has become a complex problem for the clinical practitioner. An understanding of the pharmacology, pharmacokinetics, and in vivo biological activity of antimicrobial agents is needed, as is an understanding of the variables that may influence patient compliance with medication regimens. Although UTIs are usually treated for 10 to 14 days, shorter treatment schedules of seven to ten days or even single-dose regimens are possible. Guidelines for the treatment of UTIs are presented along with suggestions for increased patient compliance.

Around the world, there is no population clear from urinary tract infection (UTI), particularly among women. UTI is considered the most predominant bacterial infection. This study aimed to detect the incidence of the most common major uropathogens in patients severe from urinary tract infection with antibiotic sensitivity tests that assist urologist doctors for appropriate antimicrobial empirical therapy.Methods: This study was carried in a private laboratory in Babil city, Iraq from May 2019 to May 2020. Totally 70 individuals suffering from clear symptoms of UTI, as well as, 20 healthy persons participated in this study as a control group. Then, the standard microbiological methods carried out to isolate and identify bacterial species. Antimicrobial susceptibility tests were performed using different antimicrobial discs by applying the Kirby–Bauer disc diffusion method.Results: Totally, 90 specimens were obtained from them 20 control group, 19 with no growth, and 51 patients with bacterial growth distributed as 43 (83%) females and 8 (17%) males. E. coli were the most common predominant organisms. All isolates were showed a high rate of resistance to evaluated cephalosporins 100% and 82% to cefotaxime and ceftriaxone respectively, while very low resistance recorded in Aminoglycosides 20% and 13% to Gentamicin and amikacin respectively. Most age group infected with UTI was 21-40 years old.Conclusion: The current study showed an increasing burden of urinary tract infection caused by various bacteria implicated in UTI that causes changeable sensitivity to various antimicrobial agents. Therefore, in clinical use appropriate medications should be selected based on the data obtained from antimicrobial susceptibility tests.
