زمینه مطالعه: آلودگی به Ehrlichia canis که یک باکتری گرم منفی داخل سلولی اجباری با پراکندگی جهانی است منجر به ایجاد ارلیشیوز مـونـوسیتـی سـگ سـانـان میشود. هدف: هدف از انجام این مطالعه بررسی شیوع آلودگی E. canis در سگهای ترومبوسیتوپنیک با استفاده از روشnested PCR و ارزیابی نقش تشخیصی ترومبوسیتوپنی در این آلودگی است. روش کار: چهل نمونه خون جمع آوری شده از سگهای ارجاعی به بیمارستان آم...
Doxycycline is the treatment of choice for canine monocytic ehrlichiosis (CME), a well-characterized disease and valuable model for tick-borne zoonoses. Conflicting reports of clearance of Ehrlichia canis after treatment with doxycycline suggested that the disease phase during which treatment is initiated influences outcomes of these treatments. The purpose of this study was to evaluate the eff...
Ehrlichia (E.) canis is a Gram-negative obligate intracellular bacterium responsible for canine monocytic ehrlichiosis. Currently, the genetic diversity of E. canis strains worldwide is poorly defined. In the present study, sequence analysis of the nearly full-length 16S rDNA (1,620 bp) and the complete coding region (4,269 bp) of the gp200 gene, which encodes the largest major immunoreactive p...
To verify the presence of cross-reaction among leishmaniosis, ehrlichiosis and babesiosis in serological diagnostics used in human visceral leishmaniasis control programs, serum samples from leishmaniasis endemic and non-endemic areas were collected and tested by Indirect Fluorescent Antibody (IFAT) and Enzyme-linked immunosorbent assay (ELISA). All serum samples from endemic areas were positiv...
Ehrlichia canis is an intracellular pathogen that causes canine monocytic ehrlichiosis. Although the role of antibody responses cannot be discounted, control of this intracellular pathogen is expected to be by cell mediated immune responses. The immune responses in dogs immunized with inactivated E. canis organisms in combination with Quil A were evaluated. Immunization provoked strong humoral ...
Rhipicephalus sanguineus s.l. and Ctenocephalides felis are considered the most prevalent ectoparasites of dogs in Philippines. Vector-borne pathogens (VBPs) these pose health risks to humans animals. This study aimed confirm morphological molecular identity tick flea species parasitising Metro Manila (Philippines) molecularly investigate possible presence Bartonella spp., Rickettsia Ehrlichia ...
ABSTRACT This study evaluated by molecular methods the presence of major canine tick-borne agents in ticks infesting domestic dogs a hospital population neglected area southern zone São Paulo Metropolitan region, which is characterized an extensive urban surrounded and interspersed forest remnants original Atlantic rainforest. During 2017, 106 tick specimens - 71 adults 33 nymphs Rhipicephalus ...
To investigate the species distribution of Ehrlichia present in Missouri dogs, we tested 78 dogs suspected of having acute ehrlichiosis and 10 healthy dogs. Blood from each dog was screened with a broad-range 16S rRNA gene PCR assay that detects known pathogenic species of Ehrlichia and ANAPLASMA: The species was determined by using species-specific PCR assays and nucleotide sequencing. Ehrlich...
