Ehrlichia canis is an obligate intracellular rickettsial agent that is transmitted by a brown dog tick called as Rhipicephalus sanguineus which is considered as the principal vector of this disease. A 3-year-old male Doberman dog weighing 25 kg is presented with the history of inappetence, fever, weakness, anemia, scanty feces, hemoglobinuria, shrunken eye ball with mild corneal opacity and reluctant to walk due to pain in the joints. Clinical examination revealed elevated rectal temperature of 104.30F, tachycardia, increased respiratory rate and pale mucous membrane. Blood and serum samples were collected for hematology and serum biochemistry respectively. On blood smear examination with Giemsa staining, Ehrlichia morulae were noticed in monocytes suggestive of Canine Monocytic Ehrlichiosis / Tropical Canine Pancytopenia.

Examination of ticks collected from ehrlichiosis positive dogs revealed the occurrence of Rhipicephalus sanguineus. The distribution of ehrlichiosis in dogs is related to the spreading of vectors. Ehrlichia canis is the etiologic agent of canine monocytic ehrlichiosis (CME) and recognized as the most prevalent tick-borne disease affecting dogs and is transmitted by the brown dog tick Rhipicephalus sanguineus with an expanding global distribution. Infection of the vertebrate host occurred when an infected tick ingested a blood meal which in turn contaminated the feeding site with its salivary secretion. Blood transfusions from infected donors can also transmit the organisms. Hence, identification of ticks is necessary to detect the disease affecting dogs.

Tick borne pathogens present a significant health challenge to animals and human because a single tick may transmit multiple pathogens to a mammalian host during feeding. The present study detected tick-borne pathogens from pet dogs. A total of 666 ticks were collected from 144 pet and sheltered dogs in Egypt from April to September 2018. For hemolymph, midgut and salivary gland smears 546 ticks were used as well as 360 egg smears from 120 female tick were examined by light microscope. The infected ticks were prepared for transmission electron microscopy (TEM). Ticks were identified; Rhipicephalus sanguineus. Light microscopy showed infection rates of 44.69%, 68.50% & 15.75%, in hemolymph, midgut and salivary gland, respectively. H. canis recorded the highest rates in hemolymph and midgut (35.89% & 49.82%, respectively), but Theileria spp. was the lowest (0.73% & 2.93%, respectively). In salivary gland smears, Babesia canis. was detected in 13.55% and Theileria spp. in 1.83%. Mixed infection in same tick was recorded in 4.76% &0.37% in midgut and salivary gland smears, respectively. Babesia canis stages were recovered from 15% of egg smears. R. sanguineus was natural infected by Babesia, Theileria, Hepatozoon and Anaplasma phagocytophilum as well as mixed infections of protozoa accompanied by a complicated sign of diseases and failure in accurate diagnosis.

Coereba Flaveola

During a survey for ectoparasites on birds in a small reserve of the Brazilian cerrado (savannah) a male adult Rhipicephalus sanguineus tick was found attached to the eyelid of the bird Coereba flaveola. Both tick and bird are presently common in Brazil, however, to best of our knowledge, the association of this tick species with this bird species has not been reported before. This observation may be an accidental finding but might also be an unknown route for the dissemination of the tick. The species R. sanguineus was introduced in the country with the colonization and should be considered a research target for the surveillance of tick-borne diseases.
