This study was designed to investigate the incidence of ectoparasite infestation among stray dogs in Gwang-ju City, Republic of Korea. A total of 103 stray dogs collected in the Animal Shelter of Gwang-ju City from November 2003 to August 2005 were investigated in this study. Ectoparasites of one or more genera were detected in 45.6% (47 / 103) of the dogs(More)
The components of Magnolia obovata are known to have many pharmacological activities. In this study, we investigated the effects of obovatol, a neolignan compound isolated from the leaves of M. obovata, on nitric oxide (NO) production and NF-kappaB activity in lipopolysaccharide (LPS)-activated RAW 264.7 cells. The results show that obovatol (1-5 microM)(More)
We describe coinfection with Hepatozoon sp. and canine distemper virus (CDV) in a yellow-throated marten ( Martes flavigula koreana). We found Hepatozoon cysts in muscular tissue and viral inclusion bodies in the brain. Hepatozoon sp., and CDV was confirmed in blood and brain, respectively, by PCR.
A protein chip based on surface plasmon resonance imaging (SPRI) was developed for detecting fish iridovirus antibody using a recombinant 50-kDa fragment of major capsid protein (MCP) as an antigen. The diagnostic potential of SPRI for measuring antibodies to the iridovirus MCP was compared with that of a conventional enzyme-linked immunosorbent assay(More)
Various species of Eimeria have different prepatent times and predilection sites, but their life cycles in infected poultry are similar. Practically speaking, chickens can be continuously exposed to various Eimeria species through environmental contamination. Furthermore, storage condition of the oocysts influences subsequent challenge infectivity, since(More)
