BACKGROUND Pneumonia accounts for approximately 2 million deaths annually among children aged <5 years, with most of these deaths occurring in Africa and southern Asia. The South Asian Pneumococcal Alliance (SAPNA) network in Nepal is generating local epidemiological data to assist in the development of national and regional policies for prevention of(More)
With a view to detect specific M. tuberculosis infection, mycobacterial proteins were purified initially by ammonium sulphate precipitation followed by ion-exchange chromatography. Out of the three fractions, namely P1, P2 and P3 precipitated with increasing concentrations (0-25%, 26-65% and 66-100% respectively) of ammonium sulphate, P2 fraction was found(More)
A prospective study was conducted to determine the magnitude of morbidity and mortality caused by acute respiratory infections (ARI) among children under 5 years of age and to assess the feasibility of reducing mortality owing to ARI by the use of community health workers. Villages selected for this study were situated on the south-west edge of Kathmandu(More)
Porins were prepared from smooth strain of Salmonella typhi 0-901 and chemotype of rough mutant of S. typhimurium Ra-30. Mice were immunized with both the porin preparations in different groups and challenged with S. typhimurium LT2-71 and S. enteritidis SH-1269. Porin immunized mice showed significant protection (P < 0.01) against challenge with homologous(More)
Porins were prepared from smooth strain of Salmonella typhi 0-901 and chemotype rough mutant of S. typhimurium Ra-30. Porins could significantly stimulate the immune systems of mice. Immunization of mice with the porins provoked synthesis of anti-porin antibodies. Macrophages from the immunized mice showed increased capacity to generate oxygen free(More)
Calmodulin-like activity has been reported for the first time in mycobacterial species, namely Mycobacterium tuberculosis BCG and M. smegmatis ATCC 14468. The activity was mainly located in the soluble fraction of the mycobacterial cells, Radioimmunoassay revealed maximum levels of calmodulin in young growing cells (early logarithmic phase of growth).(More)
To compare the efficacy of a short course of ceftriaxone with a standard course of chloramphenicol for typhoid fever, a randomized trial was conducted in 46 patients (30 adults and 16 children) who were blood culture-positive for Salmonella typhi or S. paratyphi. Ceftriaxone was given intravenously once a day for three days to 15 adults at a dose of 2 g/day(More)
Birth weight is an important determinant of infant's well being as low birth weight is known to increase the risk adult onset of diseases like type-2 diabetes and ischemic heart disease. Maternal weight gain is one of the most important independent predictors of infant birth weight. Institute of Medicine of the National Academics, USA has recommended that(More)
