| epizootic of concurrent cutaneous streptococcal abscesses and swinepox in a herd of swine. | concurrent cutaneous abscesses and swinepox were observed in a herd of swine. an ungroupable hemolytic streptococcus was isolated from the abscesses. tests indicated that streptococci isolated from different swine were similar if not identical. swinepox lesions were observed on swine only after weaning. lice (haematopinus suis) were numerous on the suckling and weaned swine and appeared to be resistant to lindane. abscesses, swinepox, and lice were eliminated after the swine were treated with an ... | 1978 | 205529 |
| [experimental studies on the course and the effects of pediculosis in domestic swine]. | weaned piglets, aged between six and eight weeks, underwent one single experimental infection, using few imaginal stages as well as second and third larval stages of haematopinus suis. louse populations of various densities developed on animals of the same litter under the same keeping and feeding conditions. no unambiguous reduction in body weight increase was observed throughout the two months of the experiment. even pigs with 2,107 or 2,135 adult lice and their larval stages were not affected ... | 1979 | 547915 |
