Objective. To develop a diagnostic algorithm, a rational method of treatment, and principles of preconception care in women with herpes-associated recurrent vulvovaginal candidiasis (RVVC).Materials and methods. We examined 68 patients with herpes-associated RVVC and 20 gynecologically healthy women.Results. It has been found that in RVVC it is necessary to study vaginal swab culture with the determination of the microorganism and its biofilm-forming ability in combination with viral DNA detection by the polymerase chain reaction (PCR) in vaginal secretion, determination of the IgG titer to the herpes simplex virus (HSV), the avidity index to HSV I and II. In the presence of laboratory-confirmed RVVC and HSV infection, it is necessary to assume the presence of an atypical course of HSV infection followed by complex antiviral and antimycotic therapy.Conclusion. The use of the developed algorithm of diagnostic and treatment interventions as preconception care makes it possible to address symptoms, reduce relapse rates and extend a non-relapse interval, prepare women with the mixed-infection for favorable pregnancy outcomes.

Abstract Background This study was aimed to determine the prevalence of qnr genes among fluoroquinolone-resistant Escherichia coli (FREC) isolates from Nigeria. Antimicrobial susceptibility testing was performed by disc diffusion technique. Polymerase chain reaction was used to identify Escherichia coli (E. coli) and for the detection of qnr genes. Results A total of 206 non-duplicate E. coli were isolated from 300 clinical specimens analyzed. In all, 30 (14.6%) of these isolates were FREC; the resistance to fluoroquinolones among these 30 FREC showed 80% (24), 86.7% (26), 86.7% (26), 100% (30), 86.7% (26), 93.3% (28) and 86.7% (26) were resistant to pefloxacin, ciprofloxacin, sparfloxacin, levofloxacin, nalidixic acid, ofloxacin and moxifloxacin, respectively. The distribution of FREC among the various sample sources analyzed showed that 14%, 10%, 13.3%, 16.7% and 20% of the isolates came from urine, stool, high vaginal swab, endo cervical swab and wound swab specimens, respectively. More FREC were isolated from female samples 73.3% (22) compared to male samples 26.7% (8) and were more prevalent among the age group 26–35 years (40%). Twenty eight out of the 30 (93.3%) FREC isolates possessed at least one fluoroquinolone resistance gene in the form of qnrA 10 (33.3%) and qnrB 18 (60%), respectively; qnrS was not detected among the FREC isolates analyzed and 13.5% of the isolates possessed both the qnrA and qnrB genes. Phylogenetic analysis showed that these isolates were genetically diverse. Conclusions These findings suggest a possible resistance to fluoroquinolone is of high interest for better management of patients and control of antimicrobial resistance in Nigeria.
