DERMATITIS DUE TO SARCOPTES SCABIEI AND RHIPICEPHALUS SANGUINEUS ACCOMPANIED BY ANAPLASMOSIS IN SHIH-TZU MIXED DOG

Abstract

Dermatitis is a skin disorder that can be caused by a variety of things, including ectoparasites such as mites and ticks. A tick infestation is often accompanied by a bacterial infection in the blood. The case dog is a Shih-Tsu cross dog named Pico, female, 3 years old. The case animal had complaints of itching for 12 weeks and had previously experienced tick infestation. Physical examination, the hair looked dirty and dull, the animal's skin showed erythema, hyperpigmentation, crusting, scale and Rhipicephalus sanguineus ticks were found. Examination of skin scrapings found Sarcoptes scabiei mites. Complete haematological examination showed normochromic microcytic anemia and thrombocytopenia. The results of the blood smear showed the presence of Anaplasma sp in the erythrocytes. Examination of the test kit showed that the dog was a positive case of Anaplasma sp. Based on the results of the examination of case dogs, they were diagnosed with dermatitis due to Sarcoptes scabiei and Rhipicephalus sanguineus accompanied by anaplasmosis. Case dogs were treated with ivermectin 300 mcg/kg BW subcutaneously at intervals of 14 days, topical therapy with sulfur soap and bathed twice a week, doxycycline 5mg/kg BW once a day orally for 28 days. Symptomatic therapy, diphenhydramine HCl 1 mg/kg BW intramuscularly and chlorpheniramine maleate 2 mg twice daily orally for 14 days. For supportive therapy, 1 ml of B-complex vitamins intramuscularly and vitamins B12 and Fe orally once a day for 28 days. After 21 days of therapy, the dog's condition improved, the frequency of pruritus decreased, the lesions decreased, the hair started growing, no ticks were found and the hematology results showed an increase in RBC, Hb and platelets from the initial condition. Pet owners recommend disinfecting the environment to break the life cycle of ticks and keeping dogs in cages to prevent transmission to healthy animals.
