Clinically normal horses developed cellular immunity to Sarcocystis neurona following IM vaccination with a commercial killed S. neurona vaccine, as indicated by the development of measurable anti-S. neurona IgG antibodies and additional intradermal skin testing. Large-scale independent assessments of the vaccine's performance and safety are in progress under field conditions. The next step in ...

Monitoring the health of wildlife populations is important for understanding and controlling the risk of infections to livestock, humans and/or other wildlife. In this paper, we analyse the results of surveys of parasites and non-specific signs of diseases carried out on organs from 638 red and 107 sika deer culled in four regions of Scotland between 1991 and 1997. Infections of the lung by Ela...

Sarcocystis nesbitti is a parasite responsible for a biphasic eosinophilic febrile myositis syndrome in two recent outbreaks in Malaysia. We demonstrate Th2 cytokine polarization in infected travelers, an overall cytokine production decrease in the early phase of the disease suggestive of initial immunosuppression, and elevated levels of proinflammatory and chemotactic cytokines in the later my...

The latex of Calotropis gigantea is a rich source of useful components that has medicinal properties and one of the main applications is in controlling the heart muscle. The crude latex extract contained many proteins, which are highly basic in nature and exhibited strong dilatation activity. Blood vessel experiment of the latex from Calotropis gigantea was studied in the green frog (Rana hexad...

Natural products and herbal remedies used in traditional folklore medicine have been the source of many medically beneficial drugs because they elicit fewer side effects, relatively cheap, affordable and claimed to be effective. However, in order to make these remedies acceptable to modern medicine, there is a need to scientifically evaluate them to identify the active principles and to underst...

A sarcocyst is described from the biceps femoris muscle of a dog using both light and transmission electron microscopy. The sarcocyst was spherical to ovoid and measured 47 x 52 /um inclusive of the wall. The wall was palely eosinophilic, approximately 2.3 jum at its widest margin, and 0.9 Mm at its narrowest margin. Cyst wall projections were barely visible in histological sections. Ultrastruc...
