| inos expression is stimulated by the major surface protein (rwsp) from wolbachia bacterial endosymbiont of dirofilaria immitis following subcutaneous injection in mice. | the bacterial endosymbiont wolbachia of several species of filarial nematodes plays an important role in the inflammatory pathology of filariasis. nitric oxide (no) production has also been implicated in the immune response during filarial infections. here we present data indicating that a recombinant wolbachia surface protein (rwsp) induces inos mrna expression and no production, as well as ifn-gamma and a th1-type antibody response, in inoculated balb/c mice. this effect is not observed when m ... | 2007 | 17126589 |
| comparative evaluation of a point-of-care immunochromatographic test snap 4dx with molecular detection tests for vector-borne canine pathogens in hong kong. | abstract there are no comprehensive studies on the performance of commonly used point-of-care diagnostic enzyme immunoassay for common arthropod-borne canine pathogens. a comparative evaluation of an immunochromatographic test for these infections with a comprehensive polymerase chain reaction (pcr) test panel was performed on 100 pet dogs and 100 stray dogs without obvious clinical symptoms. of the 162 positive test results from both immunochromatographic test and pcr, there was 85.2% concordan ... | 2011 | 21612526 |
| survey of canine tick-borne diseases in lábrea, brazilian amazon: 'accidental' findings of dirofilaria immitis infection. | blood samples were collected from 99 domestic dogs from the urban and rural areas of the lábrea municipality, state of amazonas, brazil. canine serum samples were tested by immunofluorescence assay against rickettsia spp., which revealed that only 3.0% (1/33) and 7.6% (5/66) of the dogs from urban and rural areas, respectively, reacted positively to at least one rickettsia species. dna was extracted from canine blood and tested by a battery of pcr assays targeting protozoa of the genera babesia ... | 2017 | 25517525 |
