Genetic Profiling of Pathogens Associated with Pyroxia of Unknown Origin Treated for Plasmodiasis in Bayelsa State, Nigeria

Abstract

Antimicrobial resistance of Salmonella is an increasing problem and has become a public health issue worldwide. Moreover the evidences on hazard of therapeutic failure due to the increasing incidence of antimicrobial resistance among typhoidal antibodies and malaria are on the increase. This study was aimed at the genetic profiling of pathogens associated with Pyroxia of unknown origin treated for Plasmodiasis in Bayelsa State, Nigeria.  A total of 1200 samples (200 Stool and 1000 blood) were collected from consented subjects in Federal Medical Center and Niger Delta University Teaching Hospital Bayelsa State, Nigeria. Blood samples were used for detection of Malaria parasites and Typhoidal antibodies while the stool samples were used for culturing on Salmonella-Shigella Agar. Antibiotic sensitivity of the pure isolates were carried out using sensitivity disc, biochemical analysis using API 20E was carried out to actually differentiate bacterial from each isolates and finally by genetic profiling of the resistant genes of the pure isolates using polymerase chain reaction. Antibiogram of the isolates showed high resistance to Oxacillin (73.6 %), Ampicillin (66.6%), Tetracycline (60.0%), and Erythromycin (53.3%) while Gentamycin, 22(73.3%), Chloramphenicol 18(60%) and Azithromycin 18(60%) had the highest sensitivity. The distribution of resistant genes from the genetic profiling showed that out of 20 amplified isolates, NDM resistant genes were 17(85%) followed by Bla TEM genes 14(70%) followed by CTXM and SHV genes as 11(55%) and 10(50%) respectively. The bacterial isolates showed high AMR and MDR to the commonly used antimicrobial drugs and the distribution of ESBL genes revealed a high level of resistant genes in Bayelsa State.
