Molecular evidence of Ehrlichia canis, associated risk factors and hematobiochemical analysis in client owned and shelter cats of Pakistan.

Ehrlichiosis is an infectious disease caused by Ehrlichia canis (E. canis) genus and arthropod vectors. It is considered endemic in many parts of the world among dogs. But due to lack of research on cats, there isn't enough information available. The limited reports available on feline Ehrlichiosis relied on the detection of morulae in leukocytes. The current study was designed to detect the molecular prevalence of E. canis in cats along with associated risk factors and hematological analysis. A total of 384 blood samples from cats were collected from various veterinary hospitals and shelter homes and tested by microscopy and Polymerase Chain Reaction (PCR) to identify E. canis. The prevalence of E. canis has been reported at 5/384 (1.30%) and (14/384) 3.65% in cats through microscopy and PCR respectively. DNA sequences revealed significant resemblance with each other and variable resemblance with other Ehrlichia spp. sequences of different species from various countries already deposited on NCBI. Moreover, hematobiochemical and risk factor analysis were also carried out revealing significant results. This study reports first molecular detection of E. canis in client-owned and sheltered cats located in District Lahore, Punjab, Pakistan. Further studies should be conducted to identify its occurrence in the feline population of Pakistan so that control and prevention strategies must be planned accordingly. Due to the zoonotic impact of this pathogen and in perspective of one health, endemic regions of the disease should be identified and possible control measures should be implemented in these regions to minimize the spread of disease to non-endemic regions of the world and from animals to humans.

Comparative efficacy of diminazene diaceturate and diminazene aceturate for the treatment of babesiosis in horses.

The present work was conducted to study the comparative efficacy of two anti-protozoan (babesicidal) drugs on the recovery and health of horses. A total of 80 horses, showing typical clinical symptoms of the disease, were selected for this study; the presence of babesiosis was confirmed through blood smear examination. These animals were divided into two groups i.e. A and B. Horses of Group A, were treated with diminazene diaceturate, while horses of Group B were treated with diminazene aceturate. Efficacy of the drugs was determined by the reversal of clinical signs and a negative blood smear examination. The efficacy of diminazene diaceturate was demonstrated to be 80% while diminazene aceturate was found to have 90% efficacy against babesiosis.
