Abstract

This study investigates the prevalence of Group B Streptococcus (GBS) and the potential inhibitory effects of bacteriocin-like substances produced by Lactobacillus species in pregnant women in Wukari, Taraba State, Nigeria. Lactobacillus species, known as non-pathogenic Gram-positive rods, are commonly found in the vaginal microbiota of healthy premenopausal women, where they play a crucial role in maintaining vaginal health through their antimicrobial properties. The study aimed to determine the incidence of GBS colonization and explore the antimicrobial activity of crude and partially purified bacteriocin-like inhibitory substances from Lactobacillus isolates against both Gram-positive and Gram-negative bacteria. A total of 50 vaginal swab samples were collected from pregnant women. The results revealed that 11 women (22%) were colonized by Group B Streptococcus, while 14 women (28%) tested positive for Lactobacillus presence. The bacteriocin-like inhibitory substances produced by the Lactobacillus isolates demonstrated significant antimicrobial activity against GBS, with optimal inhibitory effects observed at 30°C and pH 5.5. Furthermore, antibiotic susceptibility testing showed that ciprofloxacin, erythromycin, chloramphenicol, and streptomycin were effective against GBS isolates. The findings underscore the potential role of Lactobacillus-derived bacteriocins as natural antimicrobial agents in the prevention and control of GBS infections, particularly in pregnant women. This study also reinforces the importance of monitoring GBS colonization due to its implications for maternal and neonatal health.

Abstract

H. pylori are microaerophilic organism and a Gram negative bacterium which is found in the alimentary canal. It causes chronic gastritis and gastric ulcers. It is also linked to the development of duodenal ulcers and stomach cancer, conditions that were not previously believed to have a microbial cause. These study aim to determine the prevalence of Helicobacter pylori infection among suspected peptic ulcer patients attending General Hospital Wukari, Nigeria. A total of one hundred (100) blood samples were collected from consenting patient attending General Hospital, Wukari. Demographic information such as age and sex of each participant was obtained. Blood samples were collected by venipuncture. 5mL of blood was collected from each patient into well labelled ethylene diamine tetraacetic acid (EDTA) vacutainer tube. The Rapid Test kit was used for the qualitative detection of H. pylori surface antigen in serum/plasma. It utilises a combination of monoclonal and polyclonal antibodies to selectively detect elevated levels of H. pylori in serum/plasma. Consenting patients who participated in the study were between the age ranges of 1 to 95 years. Total prevalence of H. pylori was observed is 66%. The male gender was more infected with H. pylori infection 71.9% than the female counterparts with 58.13%. Out of the total patients 66% of the study patients tested positive for H. pylori. Among them, 60% were male and 40% were female. The age breakdown showed most patients were between 16-35 years old. It shows that the prevalence of H. pylori infection by sex among outpatient which 60% of the patients were male while 40% were female. With this the prevalence of H. pylori infection among patients attending General Hospital Wukari is 66%. Despite the high prevalence of H. pylori infection among the study subjects, these infections are threats to the human health. Hence, strategies should be adopted to help combat and control these infections and their spread within the population.
