abstract the pythium spp. are known as the principle agents of seedling blight, damping-off and root rot of cucurbits. this study was performed for determination of pythium species involved in this diseases as well study their pathogenecity on different cucurbits. the numerous samples were taken at cultivation seasons 2006- 2007 from the fields of cucumber, tomato, egg plant, muskmelon, cucurbi...

Bacteria rapidly change their transcriptional patterns during infection in order to adapt to the host environment. To investigate host-bacteria interactions, various strategies including the use of animal infection models, in vitro assay systems and microscopic observations have been used. However, these studies primarily focused on a few specific genes and molecules in bacteria. High-density t...

The liver fluke, Fasciola hepatica (F. hepatica), is a common parasite of ruminants in many countries in the temperate climates and often causes important production losses in infected animals [1, 9, 11, 14, 29, 39]. Natural fasciolosis in sheep develops clinical manifestations of acute, subacute and chronic infection according to numbers of metacercaria ingested in a period of time [1, 4, 11, ...

Many scientists have worked out on the host-parasite relatiosship. The cestode parasites were attached mostly in the stomach and duodenal mucosa. Heavy infection with this cestode parasites caused inflammation, congestion(Khadap,2009). Lytocestus indicus is a caryophyllaeid cestode of fresh water fishes. During the present study on the helminth parasites of the fresh water fishes of Warangal, C...

Pancreatic ductal adenocarcinomas continue to have the worst prognosis of any adult malignancy with a five-year survival rate of less than 4%. One approach to improve patient survival from pancreatic cancer is to identify new biological targets that contribute to the aggressive pathogenecity of this disease and to develop reagents that will interfere with the function of these targets. Apart fr...

The study aimed on characterisizing guinea pig as model to AD. It was done by observation in the celuller expression of guine pig brains with an association between depletion testosterone hormone and amyloid β (Aβ) level. Two groups of male guinea pigs (Cavia cobaya), six adult old (16-32 months) and six age old (32-48 months) with testosterone depletion as a result castration. Observations of ...
