In order to prevent the transmission of cryptosporidium to the public via public drinking water systems, various surveillance systems and regulations have been implemented hitherto, in order to increase the treatment of surface water supplies. Among these techniques is the molecular surveillance for the presences of cryptosporidium in water using PCR which resulted following the cryptosporidium outbreak in Milwaukee Wisconsin in 1993 (Johnson, et al., 1995). The outbreak resulted in effective systems being implemented to improve the quality of water treatment globally as Mac Kenzie, et al., (1994) observes.

Abstract

Plasmodium falciparum is the parasite responsible for the deadly disease, malaria. The parasite is transmitted through the injection of sporozoites into the human blood stream. These sporozoites are transported in the blood stream to the liver. The sporozoites invade the hepatocytes and differentiate into merozoites. The merozoites invade the RBCs of the host; starting the blood stage of infection. The trophozoite stage ingests and degrades approximately 80% of the hemoglobin in the host cell. The hemoglobin is broken down into peptides due to enzymatic action by a metalloprotease and cysteine and aspartic proteases. Haematin is first released as a byproduct of ...
