Canine monocytic ehrlichiosis (CME) is a major thick-bone disease of dog caused by Ehrlichia canis. Detection of this causal agent outside the laboratory using conventional methods is not effective enough. Thus an assay for E. canis detection based on the p30 outer membrane protein gene was developed. It was based on the p30 gene amplification using loop-mediated isothermal DNA amplification (L...
In order to evaluate the relative sensitivity of the detection of antibodies against various antigenic proteins of Ehrlichia chaffeensis for the diagnosis of the emerging infectious disease human monocytotropic ehrlichiosis, Western immunoblotting was performed with 27 serum samples from convalescent patients with antibodies, as demonstrated by indirect immunofluorescence assay. Among 22 patien...
Ehrlichia canis, a small obligately intracellular, tick-transmitted, gram-negative, alpha-proteobacterium, is the primary etiologic agent of globally distributed canine monocytic ehrlichiosis. Complete genome sequencing revealed that the E. canis genome consists of a single circular chromosome of 1,315,030 bp predicted to encode 925 proteins, 40 stable RNA species, 17 putative pseudogenes, and ...
Nymphs and adults of hard-bodied ticks were collected in Connecticut and tested by direct and indirect immunofluorescence staining methods for rickettsiae and Borrelia burgdorferi. Of the 609 Ixodes dammini ticks examined, 59 (9.7%) harbored rickettsialike microorganisms in hemocytes (blood cells). These bacteria reacted with fluorescein-conjugated antiserum to Ehrlichia canis, the etiologic ag...
Ehrlichiosis is a zoonotic disease which has been reported from some regions of Iran. This study was aimed to determine the presence and prevalence of ehrlichiosis in suspected dogs referred to the Faculty of Veterinary Medicine, Shiraz University, Shiraz, Iran using polymerase chain reaction(PCR). Blood samples were collected from 98 suspected dogs with at least one of the five following findi...
The present study was conducted to explore the prevalence of canine monocytic ehrlichiosis (CME) in dogs and around Meerut district for its better clinical management. A total 366 dog’s blood samples were collected from Department Veterinary Clinical Complex, SVPUAT, nearby private Clinics with history tick infestation characteristic findings CME screened on basis smear examination, followed by...
Anaplasma marginale is an ehrlichial pathogen of cattle, in the order Rickettsiales, that establishes persistent cyclic rickettsemia in the infected host. Within each rickettsemic cycle, A. marginale expressing antigenically variant major surface protein 2 (MSP2) emerge. By cloning 17 full-length msp2 transcripts expressed during cyclic rickettsemia, we determined that emergent variants have a ...
A majority of the Indian dogs are ‘community dogs’, semiferal dogs which are partially dependent on the human population and feral dogs. Communicable diseases may be a problem due to overcrowding, minimal veterinary care, and a climate favouring parasites and vectors. Some reports suggest that the vectorborne diseases, such as filariosis, babesosis and ehrlichiosis, are endemic throughout India...
canine ehrlichiosis has emerged as one of the most clinically important tick-borne diseases affecting dogs. eighty-five naturally infected dogs have been investigated, the most consistent clinical signs recorded were fever, emaciation and lymphoadenopathy, anemia, monocytosis, thrompocytopenia, hypoalbuminemia, elevation in liver enzymes and total bilirubin were the most remarkable changes asso...
