Background

Little is known about the specificity of Bartonella spp. immunofluorescent antibody (IFA) assays in dogs. Bacteremia in sick dogs most often has been associated with Bartonella henselae (Bh), Bartonella vinsonii subspecies berkhoffii (Bvb), and Bartonella koehlerae (Bk). Clarification of the diagnostic utility of IFA serology when testing against these organisms is needed.

Objective

To evaluate the specificity of Bartonella IFA assays utilizing 6 cell culture–grown antigen preparations.

Animals

Archived sera from SPF dogs (n = 29) and from dogs experimentally infected with Bvb (n = 10) and Bh (n = 3).

Methods

Antibodies (Abs) to Bvb genotypes I, II, and III, Bh serotype I, strains H‐1 and SA2, and to Bk were determined by IFA testing.

Results

Serum from naïve SPF dogs shown to be negative for Bartonella bacteremia did not react with any of the 6 Bartonella antigens by IFA testing. Dogs experimentally infected with Bvb genotype I developed Abs against homologous antigens, with no cross‐reactivity to heterologous Bvb genotypes, Bh H‐1, SA2 strains, or to Bk. Dogs experimentally infected with Bh serotype I developed Abs against Bh H‐1, but not to Bh SA2 strain with no cross‐reactive Abs to Bvb genotypes I–III or to Bk.

Conclusions and Clinical Importance

Bartonella spp. Ab responses during acute experimental infections are species and type specific.  相似文献   

Cultivation of Rhinosporidium seeberi in vitro: interaction with epithelial cells     

M G Levy  D J Meuten  E B Breitschwerdt 《Science (New York, N.Y.)》1986,234(4775):474-476

Rhinosporidium seeberi, a fungus that is associated with polyp-like tumors in animals and man, was successfully cultivated. This organism stimulated proliferation of epithelial cells in vitro, producing polyp-like structures. Spores produced in culture required a period of aging or development, or both, before they were capable of reinitiating the growth cycle.  相似文献   

Antimicrobial use Guidelines for Treatment of Respiratory Tract Disease in Dogs and Cats: Antimicrobial Guidelines Working Group of the International Society for Companion Animal Infectious Diseases          下载免费PDF全文

Respiratory tract disease can be associated with primary or secondary bacterial infections in dogs and cats and is a common reason for use and potential misuse, improper use, and overuse of antimicrobials. There is a lack of comprehensive treatment guidelines such as those that are available for human medicine. Accordingly, the International Society for Companion Animal Infectious Diseases convened a Working Group of clinical microbiologists, pharmacologists, and internists to share experiences, examine scientific data, review clinical trials, and develop these guidelines to assist veterinarians in making antimicrobial treatment choices for use in the management of bacterial respiratory diseases in dogs and cats.  相似文献
