A molecular study for the detection of Ehrlichia canis was carried out on tissues obtained at necropsy from randomly selected dogs with the intention of investigating naturally-occurring canine ehrlichiosis. The tissues evaluated for the presence of E. canis included lymph nodes, spleen, liver, bone marrow, and blood. Eight of the 18 dogs included were found to be positive for E. canis by polym...

We studied ectoparasites found on Canis lupus familiaris sampled in five areas in Mueang district, Khon Kaen Province, Thailand. The prevalence of fleas and ticks as well as their density were determined in 100 dogs that did not receive treatments. A total number of 458 ectoparasites was found corresponding to two species: 25.8% Ctenocephalides canis and 74.2% Rhipicephalus sanguineus. R. sangu...

The aim of the study was to determine the frequency and associated factors of Ehrlichia canis infection in dogs. Blood samples from 150 dogs infested with ticks in 10 veterinary clinics in the city of Huanuco in Peru were collected. The dogs were randomly selected without regard to breed, age or sex. Ehrlichia canis antibodies were detected by chromatographic immunoassay.51.3% of dogs were infe...

Background: To develop a new green approach for biosynthesis of silver nanoparticles, myconanotechnology has been represented as a novel field of study in nanotechnology. In this study, we have reported the extracellular synthesis of highly stable silver nanoparticles using three species of dermatophytes: Trichophyton rubrum, Trichophyton mentagrophytes and Microsporum canis. Methods: Clinical ...

Rhipicephalus sanguineus ticks transmit Ehrlichia canis, the etiologic agent of canine ehrlichiosis. In experimentally infected ticks, only p30-10 transcript was detected among 22 p30 paralogs encoding immunodominant major outer membrane P30 proteins of E. canis. The present study revealed transcription of p30-10 by E. canis in naturally infected ticks and sequence conservation of p30-10 genes ...

Red foxes and golden jackals are the two most abundant wild carnivores of Iran which have the ability to adopt a variety of habitats and human proximity. Despite this, very few investigations on their helminth and none on their external parasites infections have been carried out in Iran. Between 2003 and 2004, a total of 79 jackals and 37 foxes were collected from 3 different climatic zones of ...

Microsporum (M.) canis is the most common fungus to cause tinea capitis in Europe, especially in the Mediterranean region and South and Central Europe. Fungal scalp infections caused by M. canis tend to be non-inflammatory. Recently, a growing number of cases of tinea capitis characterized by inflammatory infection caused by M. canis and M. gypseum have been registered. We present a case of hig...

This study compared the vector competence of four populations of Rhipicephalus sanguineus group ticks for the bacterium Ehrlichia canis, the agent of canine monocytic ehrlichiosis (CME). Ticks (larvae and nymphs) from the four populations-one from São Paulo state, southeastern Brazil (BSP), one from Rio Grande do Sul state, southern Brazil (BRS), one from Argentina (ARG), and one from Uruguay (...

South African canine babesiosis caused by Babesia canis rossi is a common clinical disease in dogs in South Africa and remains a significant cause of domestic dog mortality. To determine whether tick-repellent, 9% amitraz-impregnated tick collars (Preventic-Virbac) could prevent tick-borne exposure to B. canis rossi, 50 dogs were assigned to two groups. Group 1 (20 dogs), polymerase chain react...
