(1) A total of 3,532 females of various engorged weights was collected from all calves, resulting in a mean female tick yield of 1.78% based on the number of larvae used for all infestations.
(2) Guinea pigs exposed to 200 and 400 H. truncatum larvae elicited the greatest change in feeding efficiency during the fourth infestation.
(3) A minimum of 4 sheeps' heads, obtained weekly over 24 months from the Pretoria Municipal Abattoir, was examined for infestation.
(4) Histopathology examination from the margin of the ulcerative area confirmed the diagnosis of basal cell carcinoma, which was infested secondarily with larvae of flies.
(5) Norwegian scabies is an unusual Sarcoptes scabiei infestation.
(6) Twenty-eight Friesland calves were infested at 7 to 11 months of age with 5 000-45 OOO cercariae of Schistosoma mattheei.
(7) The relative resistance to different cattle ticks of Gudali and Wakwa cattle with different levels of Brahman breeding, grazed on natural pastures in the subhumid tropics of Wakwa, Cameroon, was assessed using pasture tick infestations.
(8) There are several etiologic agents, including bacterial and yeast infections, parasitic infestations, and trauma or irritants.
(9) The range of age of these patients was from 10 to 14 years, from low socioeconomic status; half of the cases had history of in take of infested pork meat.
(10) Six Hereford heifer calves were infested with Psoroptes ovis and compared to six uninfested control calves.
(11) 81.5% of the cowsheds, but only 20% of the pigsties were found to be infested.
(12) This exorbitant incidence of monilial infections and infestations was associated with a high frequency of complications involving the homograft as well as the hosts' gastrointestinal tract during the post-transplantation period.
(13) Western blot analysis at the time of maximum grub counts demonstrated that immunized calves responded to hypodermin A, B and C while those receiving only MPL or infested controls responded only to hypodermin B and C. The antigen-specific antibody response as measured by ELISA at maximum grub count was significantly higher in vaccinated calves than in infested controls while the response in calves receiving only immunostimulator was also significantly elevated.
(14) In primary hosts lesions were characterized by a mild increase of heterophil count later than 48 hours post-infestation and by slight eosinophil accumulations at 24 and 48 hours post-tick attachment, as well as basophil accumulation as late as 96 hours post-infestation.
(15) The advent of electron microscopy has repeatedly confirmed Whipple's original postulate that bacterial infestation might be the cause of intestinal lipodystrophy (Whipple's disease).
(16) Issues in differential diagnosis are discussed for the following findings: internal gallbladder echoes (calculi vs tumefactive sludge, air, hematobilia, parasitic infestation, cholecystosis, neoplasia, and artifacts), gallbladder wall thickening (acute cholecystitis vs acalculous cholecystitis, artifacts, ascites, hypoalbuminemia, hepatitis, and sclerosing cholangitis), pericholecystic fluid (cholecystitis vs ascites, perforated ulcer, and trauma), bile duct dilatation (biliary obstruction vs sclerosing cholangitis, biliary air, anomalous portal system, biliary atresia, Caroli disease, and cholangiocarcinoma), perinatal and neonatal biliary disease, and sclerosing cholangitis.
(17) The kinetics of specific antibodies of the blood serum of sheep experimentally infested with 80, 160 and 1000 specimens of Oestrus ovis larvae was examined.
(18) It is suggested that the salmonid sacciform cell produces a secretion which protects the fish against infestation or damage by skin parasites.
(19) The levels of gamma-globulin increased in treated groups including the group inoculated with adjuvant only, but unlike previous reports no increase in gamma-globulin or a correlation between the level of gamma-globulin and the degree of resistance acquired were observed in calves exposed to repeated tick infestations.
(20) An unusually heavy infestation of the tussock moth resulted in a high incidence of symptoms affecting the skin and mucous membranes of those exposed to high concentrations of particulate matter of this insect.
