Characterization of structural and non-structural proteins of hog cholera virus by means of monoclonal antibodies.
120 kDa, respectively, and a protein complex containing 15, 16, 27, and 55 kDa polypeptides which were further characterized. One monoclonal antibody recognized an antigenic determinant at the ...
Simultaneous vaccination of piglets against foot-and-mouth disease and classical swine fever.
Abstract: Six-week-old piglets, born of unvaccinated sows, were vaccinated against foot-and-mouth disease (FMD) with a trivalent, inactivated vaccine containing an adjuvant or vaccinated against classical ...
Effect of disinfection of drinking water with ozone or chlorine dioxide on survival of Cryptosporidium parvum oocysts.
infection level of 1,000 oocysts (0.1-ml inoculum) per mouse was necessary to induce 100% infection. Treatment of water containing 10(4) oocysts per ml with 1.11 mg of ozone per liter (concentration at time ...
Evolution of coccidial infection in commercial and domestic rabbits between 1982 and 1986.
contained greater than 100 oocysts per gram against 85% in 1979, when sulphaquinoxaline/pyrimethamine was used. Only Eimeria magna, E. media and E. perforans were detected, whereas the highly pathogenic ...
Significance of Clostridium spiroforme in the enteritis-complex of commercial rabbits.
In 33.3% of C. spiroforme-containing samples, more than one of these agents was present. There was no significant difference between the presence of these organisms in C. spiroforme-positive and ...
Spontaneous lesions in the sternums of growing rats.
Thickening of the sternal cortices and trabeculae containing prominent cement lines were less frequently occurring lesions in these sternums. These changes were absent in rats of 70 days of age. The etiology ...
An unusual case of generalized ceroid-lipofuscinosis in a cynomolgus monkey.
histochemical, and electron microscopic studies of generalized ceroid-lipofuscinosis in a cynomolgus monkey are presented. Histologically, a wide variety of tissue cells contained numerous bright eosinophilic ...
Differential responses of eubacterial, Mycobacterium, and Sphingomonas communities in polycyclic aromatic hydrocarbon (PAH)-contaminated soil to artificially induced changes in PAH profile.
Microbiology Soil Pollutants Sphingomonas Abstract: Recent reports suggest that Mycobacterium is better adapted to soils containing poorly bioavailable polycyclic aromatic hydrocarbons (PAH s) compared to ...
Sensitivity of avian Eimeria spp. to seven chemical and five ionophore anticoccidials in five Belgian integrated broiler operations.
profile, oocytes were pooled from 9 +/- 4 farms (mean +/- SD) that used the same anticoccidial program and that belonged to the same integrated broiler operation. Each suspension contained an equal number of ...
