This study was aimed at determining the seroprevalence of Chlamydia trachomatis based one demographic factors among women attending clinics in Zaria metropolis, Kaduna State. Each participant completed a researcher-devised questionnaire and quasi design was used in the selection of hospitals. Subsequently about 5mls of peripheral blood for serological analysis was obtained after informed consent. Presence of antibodies to Chlamydia trachomatis was determined using Enzyme Linked Immunosorbent Assay (ELISA) to detect IgG and screening for HIV was also done using Determine® HIV 1/2 as well as Uni-GoldTM HIV Test Kits. Out of the two hundred and seventy (270) samples collected, 32(11.9%) were positive for Chlamydia trachomatis IgG, 7(2.6%). Chlamydial infection was found to be significantly associated with level of education. There was no significant association between chlam...

However, these strains have reemerged in some countries in recent years. This study investigated the antibacterial resistance, virulence, and the genetic backgrounds of CC30-MSSA isolates obtained from patients in three tertiary hospitals. Materials and Methods: Twenty-two CC30-MSSA isolates cultured from different clinical samples were investigated using antibiotic sensitivity testing, spa typing, multilocus sequence typing, and DNA microarray analysis. Results: All 22 isolates were susceptible to vancomycin (MIC ≤2 μg/mL), teicoplanin (MIC ≤2 μg/mL), and cefoxitin but were resistant to penicillin G (n = 22; 100.0%), tetracycline (n = 12; 54.5%), ciprofloxacin (n = 15; 68.2%), cadmium acetate (n = 22; 100%), mercuric chloride (n = 13; 59.1%), and ethidium bromide (n = 3; 13.6%). The isolates belonged to sequence type, ST3...

Panton Valentine Leukocidin (PVL) is a cytolytic toxin produced by some strains of S. aureus and are mostly associated with skin and soft tissue infections and necrotizing pneumonia. Aim: To investigate the prevalence and genotypic characteristics of PVL-positive S. aureus strains cultured from patients in three tertiary hospitals in Jos, Nigeria. Methods: Two hundred and fourteen clinical S. aureus isolates were obtained from three tertiary hospitals in Jos. Polymerase chain reaction was used to detect lukSF-PV gene that encodes PVL, and sensitivity to antimicrobial agents was performed on PVL-positive S. aureus. Genotypic characteristics of the PVL-positive S. aureus was determined by spa typing and multilocus sequence typing (MLST). Results: The genes for PVL were detected in 67/214 (31.3%) of S. aureus isolates. Majority of the PVL-positive isolates were obtained from w...
