This study describes the isolation of a Toxocara canis species-specific excretory-secretory (ES) antigen and the development of an enzyme-linked immunosorbent assay (ELISA) based on this antigen. Analysis of the ES antigens of T. canis, Toxocara vitulorum, Ascaris lumbricoides and Necator americanus larval antigen was performed by SDS-PAGE followed by western blotting. A 57 kDa T. canis-specifi...
background : the aims of this study were to determine the seroprevalence of canine ehrlichiosis and risk factors of this disease in companion dogs’ population of mashhad, north east of iran. canine monocytic ehrlichiosis (cme) is a zoonotic disease transmitted by ticks, rhipicephalus sanguineus, and caused by an obligate intracellular bacterium, ehrlichia canis. methods : during september 2009 ...
We have studied functional alteration of immunocytes in mice following inoculation of Toxocara canis second stage larvae. Results indicated depression of lymphocyte blastogenesis in response to concanavalin-A, phytohemagglutinin and allogeneic non B-cells; however, B-cell polyclonal activation was not affected as indicated by the production of total IgG. In contrast, frequency of antibody ...
beta-Hemolytic Lancefield group G Streptococcus dysgalactiae and Streptococcus canis cannot be distinguished when only Lancefield typing is performed. Phenotypic testing and 16S rRNA gene sequencing identified S. canis associated with ulcer infections in dog owners. Because S. canis may be incorrectly identified (published biochemical descriptions are inconsistent), there may be an underestimat...
We report the complete genome sequence of Ehrlichia canis strain YZ-1, which was isolated from a beagle with fever, anorexia, depression, lethargy, weight loss, and thrombocytopenia. E. canis is the tick-borne agent of canine and human monocytic ehrlichiosis.
Brucella canis is a facultative intracellular pathogen that preferentially infects members of the Canidae family. Here, we report the genome sequencing of two Brucella canis strains isolated from humans and one isolated from a dog host.
The aims of this study were to determine the occurrence of Anaplasma platys and Ehrlichia canis infection in dogs in Porto Alegre, Southern Brazil; and to investigate their association with hematological abnormalities. Serum samples from 196 dogs were first tested using dot-ELISA for antibodies against Anaplasma spp. and Ehrlichia canis. Peripheral blood samples from 199 dogs were subjected to ...
Babesia gibsoni and Babesia canis are the etiological agents of canine babesiosis, a protozoal hemolytic disease with global significance. Canine babesiosis has been diagnosed by microscopic identification of intra-erythrocytic trophozoites in blood smear, and by serological testing. Here we developed a quantitative fluorescence resonance energy transfer (FRET)-PCR that amplifies a fragment of ...
In this study, rapid slide agglutination test (RSAT) antigens were produced by using homologous (Brucella canis RM6/66 and a wild B. canis) and heterologous brucella strains (B. abortus 45/20 and B. melitensis B115) for a quick, practical and economic diagnosis of B. canis infection in dogs and humans. All the test strains were grown in three different culture media, namely, trypton liquid medi...
Background: A cross-sectional study combining different serological and molecular techniques for the detection of Ehrlichia canis in dogs was carried out to determine hemopathological findings and suggestive clinical signs associated with acute, subclinical and chronic infections in the dog population of Costa Rica. Objectives: The present study describes and analyzes, in a more representative ...
