Serum samples from 51 apparently healthy breeding bulls were screened for bovine herpesvirus-1 (BHV-1) antibodies using an avidin-biotin enzyme-linked immunosorbent assay, revealing a sero-positive prevalence rate of 45.09%. Semen samples were then collected from 12 of the sero-positive and 12 of the sero-negative bulls and tested for BHV-1 antigen using both a virus isolation assay and a polym...

INTRODUCTION In sub-Saharan Africa where HIV/AIDS epidemic is predominantly generalized, majority of HIV infections occur among heterosexual couples. The majority of people do not know their sero-status. Thus, utilisation of Couples' HIV Counselling and Testing (CHCT) services remain to be critical in preventing new infections. The objective was to establish prevalence and predictors of HIV ser...

To estimate the sero prevalence of rubella among children attending a tertiary care hospital, in the age group of 1 to 14 years who have not received MMR vaccine.This was a hospital based prospective descriptive study. Blood samples were collected from 50 children aged 1-14 years and analyzed for IgG antibody titres for rubella infection by a quantitative enzyme-linked immunosorbent assay. Data...

The epidemiology of Helicobacter pylori (H. pylori) infection is related to human poverty with marked differences between developing and developed countries. Socioeconomic factors and living standards are the main determinants of the age-dependent acquisition rate of H. pylori, and consequently its prevalence. The aim of this study was to assess the risk and sero-prevalence of H. pylori coloniz...

A community-based longitudinal study was performed in the Eastern Province of Zambia, in which repeated serological samplings were done to determine the incidence of human cysticercosis. Three sampling rounds were carried out at six months intervals. A total of 867 participants presented for all three samplings. All samples were tested for the presence of cysticercus antigens using a monoclonal...

BACKGROUND In many countries in Asia, the HIV epidemic is in a concentrated phase, with high prevalence in certain risk groups, such as men who inject drugs. There is also a rapid increase of HIV among women. The latter might be due to high levels of sero-discordant couples and increasing transmission from male to female partners over time. METHODS All adult married patients initiating antire...

INTRODUCTION Variation in the proportion of individuals living in a stable HIV sero-discordant partnership (SDP), and the potential drivers of such variability across sub Saharan Africa (SSA), are still not well-understood. This study aimed to examine the spatial clustering of HIV sero-discordancy, and the impact of local variation in HIV prevalence on patterns of sero-discordancy in high HIV p...

BACKGROUND Peste des petits ruminants (PPR) is a contagious viral disease of small ruminants. Serum samples from sheep (n = 431) and goats (n = 538) of all ages were collected in a cross-sectional study in Turkana County, Kenya. The objective was to estimate the sero-prevalence of PPR virus (PPRV) infection and associated risk factors in both species. PPRV competitive enzyme-linked immuno-sorbe...

OBJECTIVES Taenia solium Cysticercosis is a leading cause of epilepsy and neurological disability in the developing world. It is caused by ingestion of the eggs of the tapeworm, T. solium Taeniasis. The prevalence of either T. solium Cysticercosis or T. solium Taeniasis in the United States in populations at risk is poorly understood. The primary objectives of this study are to perform the firs...

Introduction: Hepatitis caused by hepatitis B virus is potentially a fatal liver infection. It causes acute and chronicliver disease puts people at high risk of death from cirrhosis hepato-cellular carcinoma. The study theprevalence helps in establishing the magnitude problem.Aim: To estimate HbsAg sero-positivity among patient attending tertiary care centre.Materials Methods: Present was condu...
