Pathogenesis of notohedrosis in cats

The clinical picture of notohedrosis of the experimental cats in 100 % of cases was manifested by skin lesions in the head area ( forehead, bridge of the nose, superbrow arches and auricles).  During the experiment in animals, at the intensity of invasion of Notoedres cati of 5.8 ± 0.3 specimens of...

description The clinical picture of notohedrosis of the experimental cats in 100 % of cases was manifested by skin lesions in the head area ( forehead, bridge of the nose, superbrow arches and auricles).  During the experiment in animals, at the intensity of invasion of Notoedres cati of 5.8 ± 0.3 specimens of live ticks  in the examined smear showed  such symptoms as the appearance of small nodules and blisters (in 40 % of experimental cases), blisters, where the fur partially or completely fell out (60 %), moderate itching (30 %), general depression (20 %), local soreness including the jaws, which prevented the consumption of food, especially solid food (30 %), and as result of weight loss (10 %). According to the intensity of the invasion of 15.1 ± 0.61 specimens of live fleas in the examined swab, the clinical picture in the affected cats was more pronounced. Thus, small nodules and blisters were detected on the affected areas of the scalp in 20 % of the experimental cats; blisters with partial or complete loss of hair on them in 80 %, moderately expressed itching in 50 %, general depression in 60 %, local soreness of the jaws and difficult consumption of solid food in 80 %, weight loss and exhaustion in 60 %. In the leukogram of the blood of the cats of the experimental group, significant changes were also found compared to healthy animals. Thus, basophils (2.70 ± 0.09 %), appeared in the blood of sick animals, which were not found in healthy animals. The concentration of eosinophils was 3 times higher (2.70 ± 0.08 %) in healthy cats and 8.20 ± 0.31 % in sick cats (Р < 0.001). Among the changes in the ratio of neutrophils in the blood of cats with notohedrosis, it was noted the appearance of young neutrophils (4.80 ± 0.18 %), an increase in the number of rod-shaped neutrophils by 69.2 % (from 5.20 ± 0.25 % in healthy animals to 8.80 ± 0.32 % in sick animals, Р < 0.001) and a decrease in segment nuclear by 26.7 % (from 69.30 ± 3.26 tо 50.80 ± 1.71 % respectively, Р < 0,01). At a high intensity of the invasion of pathogens of notohedrosis (15.1 ± 0.61 specimens of live ticks in the examined swear) the changes in the morphological composition of the blood were even more pronounced. Thus, a decrease in the content of erythrocytes by 16.2 % was noted (from 7.44 ± 0.23 Т/L in healthy cats to 6.07 ± 0.19 Т/L in the infected cats, Р < 0.01) and an increase in the number of leukocytes was noted 2.4 times (from 13.90 ± 0.62 tо 32.80 ± 0.85 g/L respectively, Р < 0.001).
