Abstract
Prevalence, Morphological and Molecular Characterization of Psoroptic Mites in Smallholder Livestock in Egypt
Highlights
Psoroptic mange caused by Psoroptes mites (Acari: Psoroptidae) is one of the main skin infestations of livestock causing significant economic losses and welfare problems (Pegler et al, 2006).Psoroptes spp. are an obligatory non-burrowing mites feed superficially on lipid emulsion of lymph, red blood cells, skin cells, exudates and bacteria of skin surface by abrading the outer epidermal layer using toothed chelicerae (He et al, 2016)
Prevalence of Psoroptes mites Based on light microscope examinations, 27.4% (29/106) of buffaloes were infested with Psoroptes spp
The prevalence rate was highest in the winter (42.9 %), and lowest in the spring (11.1%) with a significance between the season and infection rate (P-values ≤ 0.05)
Summary
Psoroptes spp. are an obligatory non-burrowing mites feed superficially on lipid emulsion of lymph, red blood cells, skin cells, exudates and bacteria of skin surface by abrading the outer epidermal layer using toothed chelicerae (He et al, 2016). It causes severe pruritus, dermatitis, formation of thick scabs on skin and later, animals suffer from scratching, biting, irritation, rubbing against objects and hair loss with subsequent damage fleece or hides (Wildblood and Jones, 2006). Psoroptes infestation mainly influenced by a variety of factors such as age, body conditions seasonal conditions, management systems and rearing with other animals (El-Khodery et al, 2010)
