Proximate composition and microbiological characteristics of pre-dried Chrysichthys nigrodigitatus and Pseudotolithus typus were studied over a period of 4weeks to determine the health risks associated with delayed consumption. All analyses were conducted using standard microbiological and chemical methods. Results showed a general decline in microbiological safety and nutritive characteristics...

BACKGROUND The aim of this multicentric prospective study in India was to assess the value of several microbiological tools that contribute to the diagnosis of tuberculosis (TB) according to HIV status. METHODS Standard microbiological tools on individual specimens were analyzed. RESULTS Among the 807 patients with active TB, 131 were HIV-infected, 316 HIV-uninfected and 360 had HIV-unknown...
Preservation technologies for winemaking have relied mainly on the addition of sulfur dioxide (SO2), in consequence large spectrum action this compound, linked to control undesirable microorganisms and prevention oxidative phenomena. However, its potential negative effects consumer health addressed interest international research alternative treatments substitute or minimize SO2 content grape m...
The study was undertaken to prospectively evaluate a Streptococcus pneumoniae urinary antigen test for diagnosis of pneumococcal pneumonia among patient and control groups between 2004 and 2006. Microbiological analysis for these patients included Gram staining for sputum, sputum and blood culture. Nonconcentrated urine samples were tested using an immunochromatographic assay, the NOW S.pneumon...
1. The content of total pantothenic acid (PaA) in two foodstuffs of microbial origin was measured by standard microbiological and chick biological assays. 2. Substantially and consistently higher values were found by the chick assay than by the microbiological determination, indicating that PaA-containing compounds were present that were not utilized by the test micro-organisms but were availab...
