Rep-PCR genotyping of infectious Acinetobacter spp. strains from patients treated in Intensive Care Unit of Emergency Department (ICU of ED)--preliminary report.

PURPOSE: Strains of Acinetobacter spp. are responsible for a considerable percentage of hospital infections. These pathogens have colonized hospital environment and developed resistance to many currently available antibiotics. The aim of this study was one year-long analysis of the occurrence of multiresistant strains of Acinetobacter spp. in population of patients hospitalized in ICU of ED and determination of their genetic similarity. MATERIAL/METHODS: Subject of research was the population of patients admitted to ED of University Hospital in Bialystok in the period from 01.08.2010 to 01.08.2011. In the analysed group of patients, infections were identified on the basis of the guidelines of CDC. Identification and drug susceptibility of strains was specified using the automatic methods with the analyzer Vitek 2XL. Genotyping using Rep-PCR method in DiversiLab system was performed on strains of Acinetobacter spp. to determinate their genetic similarity. RESULTS: During analyzed period 405 patients were hospitalized, from 14 of them multiresistant strains of Acinetobacter spp. were isolated. Conducted genetic research allowed to detect 5 clones. Rep-PCR method in DiversiLab system enabled to learn that different clone of multiresistant strain of Acinetobacter spp. is responsible for variable forms of infection. CONCLUSIONS: Results of conducted research suggest that genotyping with rep-PCR method in DiversiLab system is useful tool in diagnostics of clones of multiresistant pathogens isolated from patients requiring intensive care, hospitalized in ED. Genotyping with rep-PCR method combined with epidemiological investigation enables to establish ways of spreading of multiresistant strains of Acinetobacter spp. in ED.

Ureaplasma urealyticum and Mycoplasma hominis infection in women with urogenital diseases.

PURPOSE: The aim of the study was to assess the incidence of Ureaplasma urealyticum (U. urealyticum) and Mycoplasma hominis (M. hominis) infection in women with urogenital diseases. MATERIAL AND METHODS: M. hominis and U. urealyticum was assessed in 541 women from gynaecological and STD outpatient clinics, aged 18-55 years. A Mycoplasma IST 2 kit was used for biochemical determination of mycoplasmal infections (BioMerieux). Additionally, 248 of patients were examined for Chlamydia trachomatis (C. trachomatis), Trichomonas vaginalis (T. vaginalis) and Candida albicans (C. albicans) infection. C. trachomatis was detected by direct immunofluorescence method. The standard culture methods (Biomed) were applied to detect T. vaginalis and C. albicans. RESULTS: U. urealyticum was detected in 161 (29.8%), and M. hominis in 20 (3.7%) women. U. urealyticum infection alone was observed in 37/79 (46.8%), and 1/8 (12.5%) patient had only M. hominis infection. The U. urealyticum infection showed most frequent coexistence with C. albicans (29.1%), and less frequent with C. trachomatis (13.9%) and M. hominis infection (10.1%). The highest percentage of mycoplasma-positive cultures was found in patients of STD clinic and in infertile women. In patients with ureaplasmal infection only the most common clinical symptom was vaginal discharge and vulval/vaginal irritation. In 8.1% of the women, the course of U urealyticum infection was asymptomatic. CONCLUSIONS: The incidence rate of genitourinary infections due to U urealyticum was significantly higher as compared to M. hominis infection. Sexual mycoplasmal infections were most frequently reported in the group of patients of STD clinic and correlated with age and sexual activity.

Mycoplasma hominis and Ureaplasma urealyticum infections in male urethritis and its complications.

PURPOSE: The aim of this study was to estimate the incidence of M. hominis and U. urealyticum infections among men with urethritis and its complications. MATERIAL AND METHODS: Material for analysis were urethral swabs and EPS. Mycoplasma IST 2 kit was applied to diagnose mycoplasmal infections. All patients were additionaly tested for C. trachomatis, C. albicans and T. vaginalis and Gram stain specimens were obtained to identify the presence of PMN. RESULTS: U. urealyticum was detected in 57/390 (14.6%), and M. hominis in 4/390 (1%) men. Exclusive U. urealyticum infection was found in 45 (11.5%) men, and only 2 patients had exclusive M. hominis infection. U. urealyticum infection the most frequently coexisted with C. trachomatis--5 (8.8%), next with C. albicans--4 (7%) and M. hominis--2 (3.5%) infections. Mycoplasmal infections were the most frequently found in patients aged 30 to 39 (35.1%) diagnosed with epididymitis (29.2%). The most commonly reported symptom was dysuria. CONCLUSIONS: U. urealyticum is the common pathogen among men with urethritis and its complications. The most common symptoms in U urealyticum patients were: dysuria, hypogastric pains and urethrorrhoea, however, clinical symptoms are not frequently observed.
