Abstract:

 Background: Microorganisms constitute significant fraction of the aquatic ecosystem and have been reported to be the cause of emerging novel infectious diseases in aquacultural practices. The prevalence of infectious diseases has been observed to depend on the interaction between fish pathogens and the aquatic environment. This study was conducted to assess the levels of faecal pollution markers in catfish (Clarias gariepinus) and their growing waters in selected earthen and concrete ponds in the teaching and research fish farm of the Federal University of Technology, Akure (FUTA), Nigeria in the dry (February-April) and wet seasons (May-July) of the year.

Methodology: Two earthen and 2 concrete ponds were randomly selected as sampling sites due to their frequent usage. A total of 120 grabs of catfishes from the earthen (n=60) and concrete (n=60) ponds, and 84 pond water samples from earthen (n=42) and concrete (n=42) ponds, were randomly collected over a 6-month period of study. Enteric bacteria count in the water and catfish samples were determined using membrane filtration and pour plate methods respectively. The physiochemical characteristics of the water samples were determined using standard methods. The rate of bioaccumulation of faecal indicator bacteria was obtained by dividing the log count of each organism in the catfish by the corresponding log count in the growing waters.

Abstract:

 Background: Urinary tract infection (UTI) in pregnancy is associated with significant morbidity for both mother and baby. This study was aimed at determining the urinary bacterial isolates and their susceptibility to selected antibiotics among pregnant women attending antenatal clinics of selected Hospitals in Ilorin, Nigeria.

Methodology: A total of 300 pregnant women between the ages of 15 and 44 years were selected by random sampling technique from antenatal clinics of three randomly selected healthcare facilities in Ilorin, Nigeria; Civil Service Hospital, Sobi Specialist Hospital and Okelele Primary Health Center, between July and October 2021.  Clean-catch mid-stream specimens of voided urine were collected from each participant, cultured on CysteineLactose-Electrolyte Deficient (CLED) and Blood agar plates, and incubated aerobically at 37oC for 24 hours. The presence of significant bacteriuria (≥105 CFU/ml) was determined on the culture plate using the plate count method. Antibiotic susceptibility testing to selected antibiotics was done using Kirby-Bauer disk diffusion technique. Cefoxitin (30𝜇g) was used as surrogate to determine phenotypic methicillin resistance in staphylococcus isolates, and the methicillin resistance (mecA) gene was detected by conventional PCR assay.

Dear Editor,

Since the year 2000, 31st of August of every year has been set aside by the World Health Organization (WHO) to celebrate the contributions of African Traditional Medicine (ATM). The 2022 commemoration highlights the challenges against the development of ATM in Nig-eria and how they can be overcome; how the country can maximize it to boost foreign exchange Continue reading “African Traditional Medicine (ATM) Day 2022”
