(UNIVERSIDAD AUSTRAL CHILE, FACULTAD CIENCIAS VETERINARIAS, 1995)Five control schemes to control Rhipicephalus sanguineus were evaluated in naturally infested dogs kept with their owners in the San Ramon County, Metropolitan Region Chile. Cypermethrin was poured on dogs every 20 or 30 ...
-
(1996)The swim-up and Percoll gradient techniques were evaluated for the selection of frozen bovine spermatozoa to be used on an in vitro fertilization system. The parameters assayed were: concentration, morphology, motility and ...
-
(1996)The composition of bacterial populations in copper bioleaching systems was investigated by analysis of DNA obtained either directly from ores or leaching solutions or after laboratory cultures. This analysis consisted of ...
-
(1996)Pharmacokinetics of a long-acting formula of oxytetracycline (OTC) in one formulation of dymetylacetomide, was studied in seven-cows after i.m. administration (20 mg/kg of body weight). Serum OTC concentration was measured ...
-
(1996)A group of nine Holstein Friesian calves, 9 months of age, belonging to the same herd, and not showing antibody gp 51 in two serologic control tests were used. Three of them were inoculated with 100 μl of heparinized blood ...
-
(1996)In order to obtain new information on serum alkaline phosphatase isoenzymes, sera from 7, 13 and 20 month-old foals were pro-treated with neuraminidase (sialidase of Vibrio choterae) and electrophoresed using a commercial ...
-
(Carfax Publishing Company, 1996)Diagnosis of infectious diseases in birds using direct assays such as conventional ELISA or immunofluorescence require antibody directed to IgG of each avian species. In this study, we tested binding of human C1q to different ...
-
(1996)To minimize excessive fatness of broiler chicks, a two-stage experiment was run. During the first stage, a 75% dilution of the starter diet with oat hulls was done for 0,7 or 10 days, starting on day 7 of age (treatments ...

-
(Elsevier, 1996)In the present work we have investigated the serum antibody spectrum to parasite antigens involved in human T. cruzi infection. Analysis was performed by conventional serology (IHA, IFAT and ELISA), complement-mediated ...
-
(Elsevier B.V., 1996)In an attempt to establish a protocol for the cryopreservation of the spermatozoa of the rainbow trout (Oncorhynchus mykiss), we studied the effect of various cryoprotective agents (CA) in spermatozoa motility and viability, ...
-
(1996)The avian eggshell is a complex, extracellularly assembled structure which contains both mineralized and non-mineralized regions. The composition of the hen eggshell organic matrix was examined by immunohistochemistry with ...
-
(American Association of Avian Pathologists, 1996)The histological changes in the harderian gland (HG) induced by the attenuated H-120 infectious bronchitis virus (IBV) vaccine strain and the persistence of this virus in the stroma of the gland was evaluated in chickens ...
-
(1996)The present study was undertaken to determine if a short-term prolonged growth of the ovulatory follicle (12 to 18 h after expected time of ovulation), induced by progesterone implants, would cause ultrastructural changes ...
-
(1996)Chicken anaemia virus (CAV) was isolated for the first time in Chile from thymus samples obtained from SPF chickens experimentally infected with CAV serologically positive tissues. Isolation was conducted in MDCC-MSB1 cell ...
-
(1997)An ultrasonography study of early pregnancy diagnosis was carried out in 19 alpacas and 12 llamas, after controlled matings. The aim was to determine the earliest gestational age at which pregnancy diagnosis by transrectal ...
