مقدمه و هدف: streptococcus canis باکتری گرم مثبت است که جزء باکتری های بتا همولیتیک گروه g لانسفیلد استرپتوکوکوسی می باشد.این باکتری فرصت طلب و پاتوژن به طور معمول در مخاط دستگاه تنفس فوقانی,روده ودستگاه ادراری - تناسلی وجود دارد.برخی از سویه های این باکتری به عنوان فلور طبیعی در سطح پوست یا سطوح مخاطی دیده می شوند ولی برخی دیگر باعث ایجاد بیماری های جدی و عفونت های کشنده می شوند.اگرچه به نظر م...
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...
An ocular Toxocara canis infection is reported for the first time in Vietnam. A 34-year-old man residing in a village of Son La Province, North Vietnam, visited the National Eye Hospital (NEH) in August 2011. He felt a bulge-sticking pain in his left eye and loss of vision occurred over 3 months before visiting the hospital. The eye examination in the hospital showed damage of the left eye, red...
Babesia canis and B. rossi are large Babesia species that infect dogs and cause clinical disease. The spectrum of disease is highly diverse with either parasite, but upon evaluation of field cases it has been suggested that in general B. rossi is more virulent than B. canis. This difference was also found in experimental infections using B. canis and B. rossi isolates and appeared to be related...
The capacity of a topical combination of imidacloprid and permethrin (Advantix(®)) to prevent transmission of Ehrlichia canis was studied in two groups of six dogs. One group served as controls, whereas the other group was treated. All dogs were exposed to E. canis-infected Rhipicephalus sanguineus ticks on Days 7, 14, 21 and Day 28 post acaricidal treatment. The adult R. sanguineus ticks were ...
Group G streptococci in animals usually belong to the species Streptococcus canis and are most commonly found in dogs and cats. Occasionally, Strep. canis is detected in milk from dairy cows. An outbreak of Strep. canis mastitis in a dairy herd is described. Based on results from bacterial culture and ribotyping, a cat with chronic sinusitis was the most likely source of the outbreak. Subsequen...
BACKGROUND Although tick-borne diseases are important causes of morbidity and mortality in dogs in tropical areas, there is little information on the agents causing these infections in the Caribbean. METHODOLOGY We used PCRs to test blood from a cross-section of dogs on St Kitts for Ehrlichia (E.) canis, Babesia (B.) spp., Anaplasma (A.) spp. and Hepatozoon (H.) spp. Antibodies against E. can...
In China, brucellosis is an endemic disease typically caused by Brucella melitensis infection (biovars 1 and 3). Brucella canis infection in dogs has not traditionally recognized as a major problem. In recent years however, brucellosis resulting from Brucella canis infection has also been reported, suggesting that infections from this species may be increasing. Data concerning the epidemiology ...
