Avian salmonellosis is a large group of acute or chronic diseases of birds caused by different species of the genus Salmonella. It is a problem of economic concern for all phases of the poultry industry, from production to marketing. The main aim of this study is to investigate the incidence of Salmonella species in the feed and environment of open-system poultry farms. A total of 46 samples were taken from six poultry farms, layers and broilers. The samples include poultry feed from feeders (23 samples) and litter (23 samples). Isolation of Salmonella was carried out in a selective classical medium (DCA) after enrichment in Selenite-F broth. Four Salmonella isolates represent 5% of total samples were recovered; three isolates (75%) from litter samples and one isolate (25%) recovered from water samples; no Salmonellae were recovered from feed samples. All isolates were identified at the species level using cultural characteristics and biochemical reactions. An antimicrobial sensitivity test for the four Salmonella isolates was carried out. Each isolate was tested to 10...

The global production of solid waste and lack of its management is a concern for many global populations. Also of major concern is the production of fossil fuel-based materials and substances such as medicines. Another unease observation is the destructive action of garden snails on plant materials, of which many are found in gardens and fields of farmers. The search, however, continues for procedures that could contribute to the production of bio-based products such as bio-medicines as well as actions to limit the production of solid waste, which is a major contributor to environmental pollution. Glucose a fermentable sugar, has been identified as an important feedstock for the synthesis of many bio-products. Cellulose a glucose-based biopolymer, and structural components of paper material can be degraded into glucose by cellulase a hydrolytic enzyme system. The cellulolytic action of garden snails has been used to saccharify various waste papers at different incubation temperatures, and the optimum sugar formation from these materials and % saccharification of each paper material was determined. Optimum...

Forskolin is a heterocyclic labdane-type diterpenoid extracted from the roots of the plant of Coleus forskohlii (Lamiaceae) has been studied in depth for its broad range of pharmacological properties. Coleus forskohlii aids in the control of pestilence of Uzi fly, Exorista sorbillans, and Exorista bombycis one of the gravest ecumenical pests in sericulture industry. Forskolin affected moulting; development and metamorphosis of Uzi fly and induced various types of morphological abnormalities in Uzi fly. The treated resultants of fifth instar Uzi fly maggots, a few of them died during moulting, some of them developed into maggot-pupal and pupal-adult intermediates, abnormal pupae, abnormal adults and remaining treated fifth instar maggots developed into morphologically normal adults exhibiting reduced fecundity when compared to the controls. Coleus forskohlii root extract (CFRE) exhibited growth-regulating activity on the Uzi fly. They affected pupal- adult transformation and produced intermediates along with ovarian deformities deformed adults and also affected the inhibition of pupation and adult emergence. The plant extract repressed the growth and development suggesting its use for...

This cross-sectional questionnaire based study was conducted among 200 randomly selected child bearing mothers aged 16 to 40 to evaluate their awareness regarding breastfeeding and its health benefits in urban and slum area of Dhaka city from July to December 2013. The study showed that about 46% of respondents completed higher secondary education or more and about 27% were illiterate. A significant proportion of mothers (75%) were employed while 25% were housewives. More educated mothers had significantly (p<0.001) better knowledge about colostrum milk (91.5%) about the appropriate duration of breastfeeding (81.40%) and that breast milk is the only food recommended for babies up to 6 months of age (96.90%) in comparison to that of the uneducated mothers (49.30%; 25.35% and 77.46%, respectively). Educated mothers were also significantly more likely than uneducated women to know about benefits of breastfeeding with regard to post-partum weight loss (OR=0.462, 95% CI 0.298-0.715, p<0.001), prevention of unwanted pregnancy (OR=0.064, 95% CI 0.030-0.136, p<0.001) and post-partum bleeding (OR=0.147, 95% CI 0.083-0.257, p<0.001). Awareness of recommended...

The pharmacological activity of Withenia somnifera commonly called Ashwagandha, a herb having multi-medicinal properties, was investigated against carbofuran exposed hepatic anomalies in the air breathing fish Clarias batrachus. Fishes were exposed to 1 mg/L carbofuran for three weeks to induce the toxic effects. These fishes were then fed with Withenia somnifera root extract mixed pelleted feed @ 10% of the total feed ingredients for the next 6th and 8th week respectively. The histopathological examination of hepatic tissues was done on light microscopy and transmission electron microscopy. Major changes attributed to the hepatic cells after carbofuran treatment showed irregular shape of hepatic cells, increased sinusoidal spaces, rough endoplasmic reticulum, secretary granules, dilated mitochondrial cristae and presence of kupffer cells. Amoeboid nucleus with increased heterochromatin material, granular nucleoplasm and enlargement of nucleolus, were some of the prominent histopathological alteration in the liver tissue after carbofuran toxicity at transmission electron microscope (TEM) level. The histopathological examination of liver cell of carbofuran exposed fish followed by administration of W.somnifera root extract mixed pelleted...
