Acaricide-inducible differential gene expression was studied in larvae of Rhipicephalus (Boophilus) microplus using a microarray-based approach. The acaricides used were: coumaphos, permethrin, ivermectin, and amitraz. The microarrays contained over 13 000 probes, having been derived from a previously described R. microplus gene index (BmiGI Version 2; Wang et al., 2007). Relative quantitative ...

A strain of Boophilus decoloratus, resistant to fenvalerate, was subjected to larval immersion, adult immersion and stall tests using the following classes of ixodicides: organochlorines, organophosphates, a diamidide and pyrethroids. A susceptible reference strain of B. decoloratus was used for comparative purposes. The results indicated a high level of resistance to DDT and camphechlor, sligh...

Iguratimod is a new synthetic disease-modifying antirheumatic drug intended to treat patients with rheumatoid arthritis. A new method using recombinant human CYP450s yeast cells containing c-DNA expressed P450s was applied to identify the metabolic pathways of iguratimod and to prepare its metabolite. The metabolite was isolated, and its structure was identified by quadrupole time-of-flight-mas...

The effect of agrochemicals and beekeeping treatments on drones have not been widely investigated compared to workers or queens. In the present study, we chronic exposure chemicals set (deltamethrin, acetamiprid, oxalic acid, fumagillin, amitraz) some sperm parameters histomorphology seminal vesicles. We also assessed colony development nosema load before after exposure. Thirty native Apis mell...

Abstract The aim of the study was to analyse intestinal microbiota honey bees ( Apis mellifera ) treated with amitraz. In present study, microbiological profile bee intestines showed minor changes in following application A comparison numbers bacteria and fungi revealed a positive downward trend number fungi. decreased bacteria, included E. coli especially Clostridium spp., which were not isola...

an experiment was conducted in algerian desert goats to study the effect of age and season on blood biochemical and mineral profile during different physiological stages of the goats. serum ca, mg and na levels were significantly high at birth and decreases as the age advanced. the season had a significant effect on the decreased levels of ca, mg and k and inversely on the increased levels of n...
