Efficacy of Ocimum kilimandscharicum plant extracts after four years of storage against Anopheles gambiae ss

Reducing vector-human contact is of priority in breaking the transmission chain of malaria parasites. The use of plant extracts as repellents against malaria vectors have been advocated in different studies. The feeding inhibition of four years oldOcimum kilimandscharicum in liquid paraffin or glycerin was compared with N, N-diethyl-3-methylbenzamide (DEET) using cage evaluation method. The four years old extracts...

Comparative biochemical studies of the pregnant and non pregnant uterine limbs of the frugivorous bat, Eidolon helvum

Biochemical differences existing in the two uteri limbs during the pregnant state in the fungivorous bat (Eidolon helvum) were investigated. A total of twenty female pregnant bats were studied. They were harvested on the Obafemi Awolowo University Campus at different times to assess the different stages in their gestation and uterine cycle. The animals after being carefully assessed...

Isolation of Theileria parva ring-infected erythrocyte surface antigen (RESA) homolog

East coast fever (ECF) is a severe lymphoproliferative disease of cattle caused by the intracellular protozoan Theileria parva from the phylum Apicomplexa. Gene homologs encoding antigens from other apicomplexan parasites constitute a source of vaccine candidate antigens. The ring-infected erythrocyte surface antigen (RESA) protein is a vaccine candidate for malaria caused by Plasmodium...

Cloning and expression of Theileria parva T-complex 1 protein zeta subunit ortholog

East coast fever (ECF) is a severe lymphoproliferative disease of cattle caused by the intracellular protozoan Theileria parva from the family Apicomplexa. Gene homologs encoding antigens from other apicomplexan parasites constitute a source of vaccine candidate antigens. An ortholog of the zeta subunit of T-complex protein 1 (TCP-1) which plays a role in protein folding, assembly and transport was identified...
