Sevilleta Long Term Ecological Research (LTER) Program by the University of New Mexico. While research into parasites in mammals mainly rodents (Wilson et al.‚ 1997) and other species that habituate in the Sevilleta National Wildlife Refuge has been done‚ there has not been any studies on snails and digenean parasites in the region. Understanding and mapping the physid snail and digenean parasite habitat could help

A fungal parasite called Nosema was also a key suspect investigation. Nosema is a single-celled parasite that wriggles its way into the bees intestinal tract and causes dysentery and ultimately‚ death. A seemingly viable theory‚ although‚ it still did not match the scale that would make sense for CCD. Molecular analysis was performed

Smaller lymphoid nodules can be found throughout the intestinal tract. 2. Lamina propria lymphocytes: These are lymphocytes scattered in the lamina propria of the mucosa. A majority of these cells are IgA-secreting B cells. 3. Intraepithelial lymphocytes: These are lymphcytes that are positioned in the basolateral

Cysticercosis is a disease caused by ingestion of the eggs of Taenia solium. Neurocysticercosis occurs when the tapeworm parasite infests the central nervous system (CNS). This infection is becoming increasingly common in places such as‚ Latin America‚ Central America‚ and Southeast Asia. Immigration has increased the area of infection and stopped the confinement to certain geographical areas. These infections occur via fecal-oral route and can come from fresh produce. Most of the infections can

measles patients have secondary cases (acquired through exposure at home). 1 According to Department of Health entomologist‚ Norma Joson‚ malaria is caused by four species of the Plasmodium parasite‚ namely P. falciparum‚ P. vivax‚ P. malariae and P. ovale. Only the first two are endemic to the Philippines. The parasite is primarily transmitted by the two species of Anopheles mosquito native to this country‚ the Anopheles flavirostris complex and the Anopheles maculatus complex. In the Philippines over

EPIDEMIOLOGY A person gets infected‚ by drinking water from stagnant sources (e.g.‚ ponds) contaminated with copepods containing immature forms of the parasite (juveniles)‚ which have been previously released from the skin of a definitive host. The infection can also be acquired by eating a fish paratenic host‚ but this is rare. The parasite is known to be found in Africa and India. No reservoir hosts are known‚ that is‚ each generation of worms must pass through a human.

including parasites and viruses. The toxins of these organisms are the most common cause for food poisoning. Food must be properly handled and cooked thoroughly to properly kill these harmful bacteria or prevent them from entering the body. Usually food poisoning is mild‚ but sometimes it may become deadly.

Disease causing biologic agents include viruses‚ bacteria‚ fungi‚ protozoa‚ multi-cellular parasites‚ and aberrant proteins known as prions. Transmission of these biologic agents can occur in a variety of ways‚ including direct physical contact with an infectious person‚ consuming contaminated foods or beverages‚ contact with contaminated body fluids
