BACKGROUND Herpes simplex virus type-2 (HSV-2) is one of the most common sexually transmitted infections that facilitate human immunodeficiency virus (HIV) acquisition by over two fold or more. The development of HSV-2 control methods as a measure to control HIV epidemic in high HSV-2/HIV areas has become a priority. Two out of the six high HIV prevalent(More)
Past studies with Vibrio cholerae have shown that cholera toxin (CT) is mainly responsible for inducing T helper type 2 (Th2) responses with systemic IgG1, IgE and mucosal secretory IgA (sIgA) antibodies. In this study, V. cholerae WO7, which produces novel toxin unrelated to CT, was given orally to mice in order to determine whether the strain V. cholerae(More)
Vibrio cholerae WO7 (serogroup O1) isolated from patients with diarrhea produces an extracellular toxin despite the absence of ctx, zot, and ace genes from its genome. The toxin elongates Chinese hamster ovary cells, produces fluid accumulation in ligated rabbit ileal loops, and agglutinates freshly isolated rabbit erythrocytes. Maximal production of this(More)
BACKGROUND With a population of 1.1 billion, India is considered to be a country in which effective prevention interventions could contain the development of a human immunodeficiency virus (HIV) epidemic. Heterosexual transmission accounts for 85 % of the extant HIV infections. PURPOSE This study sought to assess the feasibility of conducting a group,(More)
Dear Editor, Acute infectious diarrhoea continues to be a significant cause of morbidity and mortality in children in low income countries. Among bacterial isolates, Shigella spp and Salmonella spp are known to contribute to the high burden of this illness in children. Recent literature survey reveals a sharp declining of prevalence of S. Typhi, while(More)
The good quality laboratory services in developing countries are often limited to major urban centers. As a result, many commercially available high-quality diagnostic tests for infectious diseases are neither accessible nor affordable to patients in the rural areas. Health facilities in rural areas are compromised and this limits the usability and(More)
INTRODUCTION Acinetobacter baumannii is an important opportunistic pathogen responsible for causing nosocomial infections. Carbapenems are considered to be the drug of choice to treat infections caused by multidrug-resistant A. baumannii. The prevalent mechanism of carbapenem resistance in A. baumannii is enzymatic degradation by β-lactamases. Therefore,(More)
BACKGROUND Shigella species are an important cause of acute diarrheal disease worldwide. This study describes the prevalence of Shigella spp. serotypes and their resistance profile in Vellore, South India from 2014 to 2015. METHODS From 2014 to 2015, 338 Shigella strains were isolated from stool samples at Christian Medical College, Vellore, India.(More)
