(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 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 ...
-
(1993)Pure 125I-radiolabeled chicken IgG was inoculated intravenously into 2-week old chickens. Radioactivity in lachrymal fluid samples was first detected 10 minutes postinoculation (PI). Radioactivity levels declined up to day ...
-
(1994)A rapid, sensitive and highly specific detection method for infectious pancreatic neerosis virus (IPNV), based on reverse transcription (RT) polymerase chain reaction (PCR) has been developed. The specificity of the assay ...
-
(1994)Since circulating antibody titres against infectious bronchitis virus (IBV) often correlate poorly with protection against re‐infection, the lachrymal specific IgA level of IBV vaccinated chickens was evaluated as an ...
-
(1991)Evidence of absence of Trypanosoma cruzi kinetoplast DNA methylation by restriction endonuclease analysis. International Journal for Parasitology bd21: 863-866. Eight kinetoplast DNA samples from very different T. cruzi ...
-
(Elsevier GmbH, 1995)Multipotential hemopoietic progenitor cells (FDCP-mix) proliferate in culture medium supplemented with horse serum. When transferred to a medium without serum, cells do not proliferate and enter a quiescent state. Both ...
-
(1992)A column (CarboPac PA1, Dionex) containing an anion-exchange pellicular resin was used for the separation of phosphoryl-hexoses derived from labeled glucose microinjected into individual frog oocytes or from cultures of ...
-
(1993)DNA synthesis in epimastigote forms of Trypanosoma cruzi was studied autoradiographically by incorporation of [3H]thymidine in the nuclear and kinetoplast DNA. Both DNA were heavily labelled. Three eukaryotic DNA polymerase ...
-
(Centro de Referencia em Informacao Ambiental, 2016)We report a new locality for Batrachyla taeniata, which fills a 290 km gap in its geographic distribution. The records add a new type of habitat for B. taeniata, which was recorded in commercial plantations of Pinus radiata.
-
(Pensoft Publishers, 2017)We report the presence of Alsodes vanzolinii (Donoso-Barros, 1974) in the Maule Region, Chile extending its known geographic distribution 160 km north of its type locality. The species was recorded in exotic young plantations ...
-
(1986)Frequency of infection with Campylobacter jejuni/coli and the occurrence of IgG, IgM and complement fixing antibodies against the agent in workers in poultry abattoirs in Santiago, Chile Campylobacter jejuni/coli (Cj/c) ...
-
(1989)Some aspects of the population dynamics of the vicuña Vicugna vicugna were studied using census and field data recorded at the Reserva Nacional Las Vicuñas, I Region, northernmost Chile. Census data and mean values of ...
-
(1985)During May 1982 a total of 2235 km2 of land was surveyed in Southern Chile to estimate grey fox Canis griseus density. An area of 28 310 km2 was judged to be potential habitat for populations in the continental area including ...
-
(1982)The reaction kinetics of human liver arginase (l-arginine amidinohydrolase, EC 3.5.3.1) in terms of arginine concentration is strikingly altered by varying the pH. Lowering the pH from the optimum (9.5) toward a more ...
-
(1990)A screening of antibodies against strain M‐41 and the Dutch variant strains D‐274 and D‐1466 of infectious bronchitis virus (IBV) using the haemagglutination inhibition test (HI) was carried out in Chile. The presence of ...
-
(1990)The leukemic cell line, WEHI-3B presents a latent collagenase-like activity which is activated after trypsin treatment. The enzymatic activity is not released from cells and is specific for the degradation of interstitial ...
-
(1986)Se obtuvo tres aislados virales de aves comerciales vacunadas contra Bronquitis Infecciosa (BI), con diagnóstico presuntivo de esta enfermedad. Las características patológicas desarrolladas por los aislados 7916, 7891 y ...
-
(1988)An enzyme immunoassay on nitrocellulose, immunoblot test (IBT) was used to detect antibodies in antisera prepared against different avian infectious bronchitis virus (IBV) strains. All antisera were tested against the M41 ...
