Plasmodium causes malaria in humans. Malaria parasites (Plasmodium) are parasitic protozoan belonging to the sub-class, coccidia, and family, Plasmodiidae (Smyth, 1996). The female Anopheles gambiae mosquito is responsible for transmitting Plasmodium parasites.
Plasmodium infection in man is caused by the bite of an infected female Anopheles mosquito. This results in the disease, malaria. Malaria has serious debilitating effects on man.
Diabetes mellitus may be caused and or exacerbated by certain chemicals or compounds which elicit oxidative stress (Traverso et al., 1999, Ogugua, 2000) in the exposed individual.
Cassia occiden alis (Caesalpiniaceae) is a small tree growing 5 – 8 metres in height (Blumgarten, 1937). The leaves are compound, composite, paripinnate with 5 – 8 pairs of leaflets usually oval.
Ceftriaxone is a parenteral third generation cephalosporin, which has stronger activity against enterobacteriaceae, including penicillinase producing strains (Hubber, 1988).
Aquatic macroinvertebrates are an assemblage of aquatic community represented by members of almost all the invertebrate taxa. Most macroinvertebrate are benthic (benthos), others are planktonic or nektonic or surface water dwellers.
The anthelmintic efficacy of the aqueous extracts o neem (Azadirachta indica) leaf and stem and root barks against the hatching of eggs and the survival of larvae of nematode parasites of small ruminants were studied.
Ancylostomiasis (hookworm disease) is a disease of worldwide distribution. The most widespread of all hookworm species is A. caninum and it parasitizes dog throughout the tropics and subtropics.
Laboratory animal experimentation is an important tool for the investigation and understanding of various biological principles and study of human and animal disease mechanisms.
The effects of exposing Heterobranchus bidorsalis juveniles (14.08 ± 0.12 g) to diferent concentrations of Bonny-light crude oil (BLCO) on amylase and cretinine kinase activities were studied The exposure of the fsh to 1.00, 2.00, 400, 8.00 ml L-1 BLCO and a control for 4 days toxicity period indicated that the signiicant increases (P < 0.01) in the serum amylase (SRA) and the hepatic cytosolic amylase (HCA) activities in the fish were BLCO concentrations dependent.
An experiment was conducted to determine the effect of feed restriction on growth performance and economy of production using One Hundred and Twenty (120) ANAK 2000 broier chicks.
