Abstract 1- The possible role of animals in the transmission of mites to man has been investigated due to the public health importance of this zoonosis. 2- Microscopic examination of skin scrapings obtained from 450 animals was carried out (50cattle, 50baffaloes, 50equines, 50dogs, 50cats. 50rabbits, 50binds, 25rates, 25mice and 50sheep). 3- A total of 250persons were subjected to skin examination, including 91school children, 100adult persons out patients presented to Dermatology department in Kalyibia Hospital, and a high risk group farmers 59. 4- The prevalence rate of infested animals in examined cases amounted to : Cattle 8% Buffalo 24% Sheep 6% Rabbit 24% Dogs 8% Rats 8% Mice 8% Poultry 6% 5- Samples from equines , cats failed detection of mites. 6- Samples from rabbits , buffaloes , sheep , rats and mice revealed sarcoptic and pscroptic mites only but samples from cattle and dogs reveled sarcoptic and demodex mites , samples from poultry show Dermanssyus gallinae only. 7- Artificial infestation of rabbit by sarcoptic mites revealed mites after 24hours. 8- By examination of mites for the possibility of transmission of bacteria by Maconky agar media culture of mites, 3type of bacteria are present on media, Staph. aureus, Clostridium preferings and E.coli. 9- Mites were cultivated on Hollister media and increased in number according to time of cultivation. 10- To determine the efficacy of some available acaricides in the control of animals mites field trials were made on infected animals. In dogs : butox 0.5/litre , Neocidol (0.1%) were the most effective in the 3rd and the 4th week post treatment respectively by spray Ivomec 200mg/kg . b. wt.) proved 100% efficacy at the 5th week post treatment. In buffaloes : Neocidol 0.1% spray Butox 0.5ml/litre spray Proved 100% efficacy on the 3rd and 5th week. Post treatment respectively Ivomec, s/c at a rate of 200mg/kg b. wt. proved 100% efficacy on the 3rd week p.t. In rabbits : Ivomec 200mg/kg. b. w. , s/c infection proved 100% efficacy on the 5th week p.t. while at concentration of 400mg/kg . b. wt. on the 2nd week p.t. butox 0.5ml/litre , proved 100% efficacy at 3rd week. Neocidol at 0.1% proved 100% efficacy at 3rd week. In sheep: Ivomec (sk) 200mg/kg b.wt. proved 100% efficacy on the 5th week p.t. while at 400mg/kg. b.wt. proved efficacy 100% at 4th week p.t. Neocidol 0.1% spray. Butox 0.5ml/litre proved 100% efficacy at 3rd week p.t. In cattle : Neocidol 0.1% efficacy 100% in 3rd week p.t. Butox 0.5cm/litre efficacy 100% at 3rd week p.t. Ivomec 200mg/kg. b.wt. efficacy 100% at 3ed week p.t. 11- The public health importance of. 12- Animal mites was discussed. 13- Recommendation for control of animal mites were given . 14- The approved treatment for human mites was indicated. 15- Dermatitis in man caused by animal mites is more beign than that caused by the human mites , and the animal mites don’t excavate tunnels in human skin , spontaneous heeling may take place due to mites of animals don’t reproduce at all or do so only for short time. 16- The incidence percentages of mites dermatitis. 1) School children 8%. 2) Adults in hospitals 3%. 3) Farmers 10.2%. 17- Human infection with mites from : 1) Dogs and puppies . 2) Buffaloes , Birds , Rabbits , Rates , Mice , Sheep , Cattle , and transmitted by infested animals or by contaminated objects. |
