(2007)During the breeding seasons 2001–2005 we determined the nest measurements and characteristics of a Chilean Hawk (Accipiter chilensis) pair in an Andean Nothofagus forest of northern Patagonia (36uS; 50 km east of Chilla´n). ...
-
(1998)The presence of immunotolerant, persistently infected (IPI) animals with bovine viral diarrhoea virus (BVDV) was detected in several milking herds with abortions, repeat breeders, still births and poor growth rates, by the ...
-
(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 ...
-
(2005)The chemical composition and biological value of two dicalcium phosphates, a dihydrated one (FA) and a monohydrated product (FB), were assessed in a 2 x 3 factorial arrangement of treatments: two phosphates (A and B) and ...
-
(2005)Antimicrobial resistance is an important worldwide public health problem having a negative impact on the struggle against bacterial diseases. The WHO indicates that there exists evidence that livestock are a reservoir for ...
-
(1997)Monthly prevalence of canine rabies in Argentina (1971-1993), Bolivia (1987-1993) and Paraguay (1976-1993) were analyzed to identify seasonal cycles of the disease. Moreover, data to forecast the evolution of rabies were ...
-
(2005)Correlated selection response of United States Holstein bulls was estimated in the provinces of Bío-Bío and Malleco (Chile). The aim of this research was to obtain indicators that could estimate the profitability obtained ...
-
(1997)The effect of an adaptation period to the consumption of broiler litter (BL) on the ruminal degradability (dgr) was evaluated. The dgr of dry matter (DM), total N (TN), protein N (N x 6.25) and uric acid was determined for ...

Anticuerpos policlonales antiinmunoglobulinas de salmón; herramientas potenciales para diagnóstico (1997)Immunoglobulins (Igs) from sera of Atlantic salmon (Salmo salar) were purified with 50% saturated ammonium sulphate followed by molecular sieving chromatography using Sephacryl S-300. The fraction of purified Igs was used ...
-
(2005)Presence of the antigen of the feline leukaemia virus in serum of cats naturally infected was observed in Chile in 1989, using an ELISA test. This virus induces neoplastic as well as non-neoplastic alterations. The ...
-
(2001)Avian eggshells are natural composite bioceramics containing organic and inorganic phases. The occurrence and role of particular collagens and proteoglycans in the eggshell and their pattern of secretion by the oviduct is ...
-
(2003)This work reports the detection of canine herpesvirus type 1 (CHV-1) in Chile, confirming the strong clinical suspicion of its existence. A viral isolate, RP5, was obtained from diagnosed clinical cases such as hemorrhagic ...
-
(Universidad Austral de Chile, 2002)Mice from ACA and A.Sn strains were equally susceptible (100% mortality) to intraperitoneal infection with 2000 blood trypomastigotes from Tulahuen strain of Trypanosoma cruzi, while A.Sw and HTI strains were resistant ...
-
(1998)The biological value of three phosphate feeds and the tissue concentration of some potentially toxic elements were assessed using two raw rock tricalcium phosphates (RRPA and RRPC), a dicalcium dehydrated phosphate (DPB) ...
-
(2000)The basic biology of the potential hantavirus reservoir rodents from Chile are reviewed. The taxonomy and systematics of five endemic Muridae species, the oryzomine Oligoryzomys longicaudatus (probably the primary reservoir), ...
-
(2003)Total concentration of synovial fluid glycosaminoglycan (GAGs) and a fraction of it (GAGsT) which correspond to different GAGs from hyaluronic acid or sulfated GAGs (GAGsS) that mainly consist of chondroitin sulfate and ...
-
(Taylor and Francis Ltd., 1997)One-day-old chicks, inoculated intramuscularly (i.m.) with the chicken anaemia virus (CAV) isolate 10343, showed depression of body weight gain and anaemia, particularly between days 14 and 21 post-inoculation (p.i.). The ...
-
(1999)Serum samples from 408 sheep from different regions of Chile and 447 alpacas (Llama pacos) from the north of the country were tested for Toxoplasma gondii antibodies. The indirect haemagglutination test (IHAT) was used in ...
-
