Cytauxzoon felis, an emerging virulent protozoan parasite that infects domestic cats, is treated with atovaquone and azithromycin (A&A). Atovaquone targets parasite cytochrome b. We characterized the C. felis cytochrome b gene (cytb) in cats with cytauxzoonosis and found a cytb genotype that was associated with survival in A&A-treated cats.

Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), is one of the most important pest of vegetable and fruit crops. This polyphagous pest has a range of natural enemies including the parasitoid Eretmocerus mundus (Merect) (Hymenoptera: Aphelinidae). To determine the molecular profile and taxonomic status of Iranian isolates of E. mundus, parasitized B. tabaci samples were collected from cotton...

we studied 1038 bp of cytochrome b gene for social voles from three localities in iran. the new sequences were compared with the previous published data correspond to eight species of social voles. our results indicated that new material from west of iran belong to the two species; m. socialis and m. irani karamani. this finding led to prove more knowledge about the iranian vole distribution ra...

Chronic granulomatous disease (CGD) is a group of inherited disorders in which phagocytic cells fail to generate antimicrobial oxidants. The various forms of CGD can be classified in terms of the mode of inheritance (either X-linked or autosomal recessive), and whether the neutrophils display the absorbance spectrum of a unique b-type cytochrome important for the function of the respiratory bur...

cyp3a4 probably has the broadest catalytic activity of any cytochrome p450. it is a crucial task to test new drug candidates in a reliable system for their ability to induce expression of this enzyme. firstly, a total of 300 bp core distal enhancer of cyp3a4 xrem region (-7972/-7673) were amplified from human genomic dna. the pcr product was then ligated into a human secretory alkaline phosphat...

The current work was conducted to unveil the situation for infection by Theileria annulata in cattle Al-Hilla City, Iraq. A total of 225 blood samples (200 from suspected infected animals and 25 clinically healthy as a control group) were collected. These subjected direct slide-smearing detection using microscope DNA sequencing, targeting cytochrome b (Cyt b) gene 10 polymerase chain reaction (...

background: the adult female sand flies (diptera: psychodidae) of the subgenus larroussius are important vectors of leishmania infantum (kinetoplastida: tripanosomatidae) in meshkinshahr district, northwest of iran. four phle­boto­mus ( larroussius ) species are present in this area, i.e. phlebotomus ( larroussius ) kandelakii , p. ( la. ) major , p. ( la. ) perfiliewi and p. ( la. ) tobbi . th...
