“…Furthermore, this disease can be complicated by sensual tumors and lung abscesses, and sometimes this infection leads to starvation, which might cause death (Dorchies et al, 1993;Özdal et al, 2016). Occasionally, the larvae from frontal sinuses and nasal cavity may move into the brain leading to false gids (Patra et al, 2018).…”

The larvae of Oestrus ovis Linné, 1758 are well-known parasites of goats and sheep. Larval instars of O. ovis are described based on specimens collected from nasal cavities, frontal sinuses and base of the horns of goats from Karachi, Pakistan. Three instars of larvae are described in detail, including body coloration, dorsal and ventral body spines and D-shaped spiracles. Colored illustrations of various larval instars along with typical characters have been given. We also give a key to the third instar larva with some modifications. The mean length (15.65±4.29), width (6.043 ±1.70) and weight (356.3±168.4) of O. ovis larvae were calculated. The one way ANOVA showed significant differences (P<0.05) in length, width and weight of three larval instars of O. ovis. Larvae growth relationship showed negative allometry between weight-length and weight-width, while length-width showed isometry.

“…Larvae sometimes migrate into the brain of sheep and cause in coordination called "false gid". 4,6 Oestrosis in small ruminants causes substantial economic losses to sheep and goat producers. 6,7 The pathogenic effects cause a reduction in production and serious economic losses, which have been estimated at 1.1-4.6 kg of meat, 200-500 g of wool, and up to 10% of milk per animal.…”

“…Larvae pass through three stages or instars. 6 The female O. ovis fly is viviparous and deposits L1 in or around the nostrils. Inside the nasal cavities, the first instar larvae attach to the mucous membrane, change to second instars, move up to the sinuses and molt to L3.…”

Background: Ovine oestrosis is an economically important and widely distributed parasitic disease of sheep that is caused by Oestrus ovis larvae across the world. Despite the fact that Oestrus ovis is a common parasite in Ethiopia and that there are many sheep in the study area, there is no information on the prevalence, larval burden, predilection sites, and risk factors associated with Oestrus ovis infestation in sheep in the Dendi district of West Shewa Zone, Ethiopia. Methods: A cross-sectional study was conducted from November 2017 to April 2018, to estimate the prevalence, risk factors, and larval burden, and identify common predilection sites for Oestrus ovis larvae. A total of 180 sheep heads were randomly selected from five purposely selected restaurants in Ginchi town, Dendi district, transported to the laboratory, opened with a hand saw, and visually examined for infestations. The larvae were collected from positive sheep heads and counted. The sites where the larvae were obtained were recorded. The data were analyzed using SPSS version 20 software. Results: Of the total of 180 examined sheep heads, 104 (57.8%) were infested with larvae of Oestrus ovis. In the study, a statistically significant difference (p > 0.05) was not observed in the prevalence of Oestrus ovis in relation to all considered risk factors such as sex, age, and origin of sheep. From 104 infested sheep, a total of 664 larvae were detected in different parts of sheep heads. The mean larval intensity per infected animal with Oestrus ovis was 6.38. In this study, the minimum and maximum numbers of larvae recovered were 1 and 26, respectively. The nasal cavity, nasal sinus and frontal sinus were the predilection sites of Oestrus ovis larvae identified in this study. Conclusion:Oestrosis is an important and common parasitic disease of sheep in the study area.
