bovine teat atresia associated with horn fly (haematobia irritans irritans (l.))-induced dermatitis.	mammary gland lesions characterized primarily as mammary teat atresia were observed in a limousin beef cattle herd in eastern texas. atresia of multiple teats per mammary gland was reported in first-calf heifers at the time of calving. pathogens were not identified in eight mammary glands collected at slaughter. histology of affected glands demonstrated superficial and deep perivascular inflammation and fibrosing dermatitis of teat and mammary gland skin that resulted in formation of the atretic ...	2000	10896402
survey of resistance to permethrin and diazinon and the use of a multiplex polymerase chain reaction assay to detect resistance alleles in the horn fly, haematobia irritans irritans (l.).	a field survey was conducted in 2001 to evaluate resistance to pyrethroid and organophosphate (op) insecticides on horn flies, hematobia irritans irritans (l.), from seven ranches in the state of tamaulipas, mexico, and from three locations in central texas. filter papers impregnated with either technical permethrin or diazinon were used to measure the levels of resistance to pyrethroids and ops. a multiplex polymerase chain reaction (pcr) assay was used on individual horn flies from these field ...	2003	14765674
