Hematological Changes in Dogs and Cats With Ectoparasitosis in Northern Trans-Urals

Abstract

Skin is the most vulnerable and extensive body area in mammals. The clinical manifestation of dermatopathies may vary from minor irritation to extensive ulcers causing severe discomfort and disturbance of homeostasis. The aim of the research was to study the hematological status of dogs and cats with the most common ectoparasitosis of varying severity. The research was conducted in the period from 2015 to 2017 on the basis of the Department of Anatomy and Physiology of Northern Trans-Ural State Agricultural University and several veterinarian clinics of the city of Tyumen and the Tyumen region. For the indicated period, 19,226 domestic carnivores were studied out of which 8,602 were cats and 10,624 were dogs. It has been stated that in the case of diseases caused by ectoparasites (ticks: Sarcoptes, Notoedres, Demodex, Ixodes and Dermacentor, as well as fleas (Ctenocephalides canis) and C. felis) serious hematologic changes occur. Blood cells actively react to the painful processes occurring in the domestic carnivores; therefore, there is a quantitative change that gives important clinical and diagnostic value for determining the severity of disease and assigning of adequate treatment. The phenomena of erythrocytopenia occurred in dogs and cats under demodicosis, as well as during the ixodid tick attack. Erythrocytosis was observedduring notoedrosis in cats. The number of erythrocytes at that time has increased by 20%. In case of ectoparasitic lesions, the level of hemoglobin tended to decrease. So, ixodidoses, flea invasion and demodicosis in dogs and cats were accompanied by anemic symptoms, which in our opinion were caused by blood loss and destruction of red blood cells by biological toxins. Leukocytosis was observed in domestic carnivores affected by pruritic ticks (notoedrosis, sarcoptosis). In some cases, the amount of leukocytes increased 2.3 times. The rate of erythrocyte sedimentation at most arachnoentomoses (flea invasion of dogs and cats, dog sarcoptosis and ixodidosis) had a stable tendency to increase, which indicates the development of necrotic region, inflammatory reaction and destructive processes in sick animals.

Clinical and Hemato-biochemical Studies on Canine Anemia

“…In the term of haematological examination (Table 1), results revealed significant (p≤0.001) reduction in HCT value, TEC and Hb level in affected cases compared with healthy dogs. These results were in agreement with (Tkacheva and Glazunova, 2018). Anemia was classified as macrocytic normochromic regenerative type with prominent anisocytosis.…”

Prevalence of demodicosis in cats in and around Mhow (M.P.)

“…These findings are in agreement with findings of earlier researchers Saari et al (2009) [5] as they reported overall prevalence of demodicosis in cats 47.95%. Tkacheva and Glazunova (2018) [9] also reported overall prevalence of demodicosis in cats as 3.53 %.…”

Study of Some Biochemical and Haematological Parameters in Blood of Stary Cats Infected with Ticks

“…During feeding, Ticks secrete saliva in the dermis, which contains biologically active substances that cause an allergic reaction. When the tick punctures the skin of its host, it injects a substance that anesthetizes the attachment site and reduces the blood coagulability; However, most dogs and cats with ectoparasites have no clinical symptoms; thus, animal does not reflect any discomfort and does not feel the tick's presence (8,9,10). The Ixodes affect animal health entirely such as severe blood loss, serious hematological changes, decrease of some blood biochemical parameters, mineral levels and I Egyptian Journal of Veterinary Sciences https://ejvs.journals.ekb.eg/ trace elements [11].…”
