A total of 364 head sheep were examine from fourteen region in Al- Diwaniyah province 224 positive to infestation and larvae collected sent the laboratory veterinary medicine, October 2021 March 2022 for both sexes. The rate Oestrus ovis study areas was 61.53%. Al-Dighara abattoir had highest (82.75%) Al-Salahia lowest (17.64%). DNA extraction sequencing phylogenetic analysis used identify (16S...

The sheep bot fly (Oestrus ovis L.) causes a severe cavitary myiasis in practically all sheep and goat producing areas of the world. It is currently considered as a very well-adapted parasitic organism which is hard to fight or to eradicate [25]. Oestrosis impairs the wellbeing and performance of the hosts, affecting growth, wool and milk production [22]. As happens with other cold-blooded orga...

Larvae of Oestrus ovis (Diptera: Oestridae) are ubiquitous parasites of nasal and sinusal cavities of sheep and goats. According to the chronobiology of O. ovis infections in Sardinia and the seasonal pattern of the IgG response, the optimal period to investigate the relationships between O. ovis larval populations and intensity of local and systemic IgG antibody responses was mid-July in the s...

This study identified and characterized hydrolytic enzymes in salivary gland products of Oestrus ovis larvae. Third instars were collected from the heads of slaughtered goats. Salivary glands were extracted, their products obtained by centrifugation and the enzymatic profile determined. Optimum pH, temperature of maximum proteolytic activity, thermal stability, and resistance of salivary gland ...

A 17-year-old girl presented to the Casualty Department of St Paul's Eye Hospital, Liverpool, with a foreign body sensation in the right eye for 2 days. Two days previously she was on a beach in Palma Nova in Majorca. She thought sand had blown into her eye. She did not remember ever having been struck in the eye or face by any insects.

Ophthalmomyiasis is a parasitic eye infection. Ayoung male went on a picnic with his family. After sudden blow of wind, he had a feeling of something struck in the eye, which quickly became swollen with severe itching and lacrimation. Atotal of 19 larvae in their instar stage were removed with fine forceps under topical anesthesia and slides were prepared for their identification, which came ou...

Oestrus ovis L. (Diptera: Oestridae) is a cosmopolitan agent of myiasis in sheep and goats. The parasitic phase begins after adult females deposit first-stage larvae (L1) into the nostrils of hosts; these larvae develop into L2 and L3 in the nasal and sinus horn cavities. Sneezing and nasal discharges are the major clinical signs in infected animals. The pathogenesis of O. ovis infection is cau...
