A 12-month study was conducted in 4 communal grazing areas in the Bushbuckridge region, Limpopo Province, South Africa. The main objective was to investigate the impact of reduced acaricide application on endemic stability to bovine babesiosis (Babesia bigemina and Babesia bovis) and anaplasmosis (Anaplasma marginale) in the local cattle population. To this end 60 cattle in each communal grazin...

Recent collections of bird's nest fungi (i.e. Crucibulum, Cyathus, Mycocalia, Nidula, and Nidularia species) in northern Thailand resulted in the discovery of a new species of Cyathus, herein described as C. subglobisporus. This species is distinct by a combination of ivory-coloured fruiting bodies covered with shaggy hairs, plications on the inner surface of the peridium and subglobose basidio...

Up to date 2 species of Mallophaga have been reported from birds in Iran. Further studies in Tehran area showed that the wild birds harbour more lice. The following species of Mallophage are reported for the first time from birds in Iran. Anaticola crassicornis from Anas clypeata, Laemobothrion maximum from Falco tinnunculus Laemobothrion sp. from Aquila chrysaetos Alcedoecus annulatus from Alc...

A new species of caligid copepod, Lepeophtheirus simplex sp. n., parasitic on bullseye puffer, Sphoeroides annulatus (Jenyns) in Sinaloa, Mexico is described. The new species is distinguished from its congeners by the possession of (1) a maxillule with simple dentiform process; (2) a sternal furca with sharply pointed, curved tines; (3) a 2-segmented exopod of leg 3 with simple, slender spine o...

ticks are an important problem among zoonotic diseases. main veterinary species of hard ticks are: hyalomma sp. boophilus sp and rhipicephalus sp. among them hyalomma sp. have widespread distribution in iran and middle east. the best method to control hyalomma sp. is immunological one, by using antigens, which causes immunologic and physiologic reactions in host.bm86 is one of the best antigens...

The control of the southern cattle tick, Boophilus microplus (Canestrini), in Mexico and many other countries relies on chemical acaricides. Boophilus microplus has developed resistance to all major classes of acaricides in recent years. To gain a better understanding of the resistance and to develop resistance management strategies that benefit both Mexican ranchers and USDA's cattle fever tic...

The infection rates of Babesia sporokinetes in engorged Boophilus microplus were evaluated during a 2-year period in a dairy farm located in an area of enzootic stability. Every 14 days engorged females were collected from calves and from adult animals. Ticks were incubated at 27 +/- 0.5 degree C and 80-90% relative humidity and Babesia infection rates were determined by microscopic examination...

Ticks were collected at approximately bi-monthly intervals between June 1996 and June 1997 from crested francolins, Francolinus sephaena, and from the vegetation on a mixed cattle and wildlife farm in Limpopo Province, South Africa. The birds were infested with the immature stages of 13 tick species, of which Amblyomma hebraeum, Amblyomma marmoreum and Hyalomma marginatum rufipes were the most ...
