بررسی مطالعه عوامل ضایعات پوستی (قارچی و انگلی) در اسبهای گرگان و دشت

‭summary In this investigation have been considered skin damages factors including fungus factors which have high contagious ability and several clinical symptoms appearance and ~ith endangering the general health with the aid of parasitic factors including ticks and manges which cause disease by sucking the blood , biting and transmission a series of parasitic and microbial diseases and Poison secretion . According to planned grouping from 400 heads of horses, sampling accomplished based on horse population distribution to refer to the region from 400 heads of sampled horses, 26 heads( 6.5%) affected with skin damages and from these, 6 heads (1.5%) affected by alopecia due to mycosis with trichophyton equinum factor and 20 heads (5%) affected with contamination by tick of the tense kind and contamination caused by mange and soft ticks in common fungus and parasitic contamination cases were not observed. About the mycOSIs, the most contamination rate in the mountainous and mountain side draft horses (3 cases)and in drafthorse in the plain (2 cases) , race horse of the plain (1 case) , contamination intensity was observed in neck, cheek and legs areas respectively and it wasn,t observed in free horses.ln relation to the season the most contamination rate were reported in summer season 5 cases and then in the autumn season 1 case and it wasn,t observed in the winter and spring seasons. Influence significant difference in relation to the. diffusion the disease during the summer season rather than other seasons and more contamination prevalance in summer season and specially in draft horses in the mountain areas are due to these factors. I 1- Beginning the work season 2- Kind of working (getting in contact with materials contaminated to fungus during porterage 3- Non- observance of health , 4- Maintaining in wormth and moisture and contaminates stables . 5- suitable environmental conditions. 6- Transpiration It,s necessary to mention that with regard to the treatment of horses contanminated to fungus with LlCODERM and FYTO as Local in two stages at an interval of 1 week that in all the cases after about 45 days symptoms of disease effectedJrom 20 cases tick contamination , the most contamination rate were observed 8 cases ( in mountainous . drafthorses), then mountainside draft horses ( 6 cases) . race horses in plain (1 cases) free horses in plain (3 cases) , drafthorses in plain (1 case) that influence significant difference between contamintion rate of horses in plain region and other regions can be related to the sUitable environmental conditon( plant cover. moisture, wormth and non‬ص‭observance of health in the mountainous and mountainside regions, with a view to the kind of separated ticks , number 146 ticks were separated that the most contamination rates were related to the Hyalomma anatolicum anatolicum tick (81 cases). then Haemaphysalis punctata (59 cases) , Boophilus annulatus (2 cases) . Dermacentor marginatus (3 cases) and Ixodes ricinus (1 case) that influence significant difference between the rate of ticks distribution is due to suitable and moderate climatic condition in the regions for the growth of Hyalomma and Haemaphysalis ticks I with the view to contaminated areas of the body , the most contamination rate were observed in the areas of groin . under tail I neck, mane and ear, that influence significant difference between contamination rate of body, contaminated areas have been related to the desirable conditions and medium in groin and under tail be cause of the friction moisture , wormth throughout the year. During the various seasons. the most contamination rate .. in summer season (8 cases) , autumn (7 cases) , spring (3 cases) and winter (2 cases) were observed that influence significant difference amoung the contamination rate during various seasons are due to wormth and suitable moisture for the ticks growth during the summer and autumn seasons‬
