“…When the third instar larvae reaches the nasal passages, the host sneezes violently thus ejecting the larvae with great force (Soulsby, 1982;Marquardt et al, 2000;Taylor, 2007). The adult larvipositing O. ovis has a short lifespan of just two weeks and is known to possess affinity for its natural host sheep (Godara et al, 2010). Infection rates and larval burdens are always higher in sheep than in goats after either natural or artificial infestation (Duranton et al, 1996;Dorchies et al, 2000;Papadopoulos et al, 2001;2006).…”

Nasal myiasis or oestrosis is primarily a disease of sheep (but rarely in goats, camel, deer, dog and man) caused by the infestation of nasal cavities by the larvae of botfly Oestrus ovis. Four adult goats, aged between three and five years were presented with clinical history of onset of episodes of neurological symptoms such as ataxia, staggering gait, convulsions, circling and paddling of legs. The animals were treated but the response to the treatment was very poor. The severity of neurological signs increased with time resulting in recumbency and death of the animals. On necropsy, 19 larvae were recovered from the nasal sinuses and cranial cavity of one animal, 4 from brain of another goat and one larva each from the brain of other two animals. The Oestrus ovis larvae were confirmed based on the presence of posterior 'D 'shaped respiratory spiracles. These very rare cases of aberrant infestation of goat brain with Oestrus ovis larvae, their clinical manifestation, pathology and public health significance have been described and discussed in detail.

“…There is a consensus that the pathogenic effects of this infection cause a long-term decline of the immune response and body condition of sheep (Godara et al 2009). Adding to these problems is the difficult control of this parasitism in the environment and the great disparity of its treatments (Arslan et al 2009).…”

Oestrus ovis infection of grazing sheep during summer in southern Chile

ABSTRACT. - Oestrus ovis is a botfly whose larvae cause nasal myiasis, an environmental-dependent disease in small ruminants, generating acute and chronic injuries in the cranial cavities of sheep. Chile is a country of the southernmost worldwide distribution of this parasite, and there is few information about. Whence, the objective of this study was to approximate the epidemiological situation of O. ovis infection in Chilean sheep. From December 2009 to March 2010, a total of 87 samples were obtained by necropsy for skull inspection. The larvae were collected, and microscopically identified. The prevalence in the sampled sheep was 60.9%. From those that were infected, 85.7% (18/21) of sheep were 1 to 3 years old, constituting the stratum with the highest prevalence. The difference of infection in females and males was not significant. The high risk of infection seems to be dependent upon the environmental conditions of this southern region, especially during summer when the first larval stage (L1) could be found as the evidence. Therefore, the disease should be considered as a significant problem for this kind of livestock production.

“…There may be also erosion of the bones of the skull and damage to the brain, leading to blind staggers or false gid [6, 7]. The migratory larvae penetrate and erode the dorsal turbinate bones, frontal sinuses, and occasionally the skull bones while entering into the cerebral cavity, causing false gid [8]. Heavy infection can induce a condition known as false gid in which the affected animal becomes unthrifty and exhibits a lack of coordination and staggers around in circles [5].…”

The sheep nasal bot, Oestrus ovis (Diptera: Oestridae), is a cosmopolitan parasite commonly found in sheep and occasionally goats. Rarely a bot will migrate into the sheep brain (false gid). Following the complaint of an animal husbandman about high mortality rate in a sheep herd, the herd was clinically, hematologically, and pathologically examined exactly. Clinical, hematological, and pathological findings were described in the text. Necropsy findings showed heavy infestation with Oestrus ovis larvae. The herd was treated with Ivermectin. After treatment all patients without nervous sings were recovered. Patients with nervous signs did not respond to treatment, but new cases of disease did not occur and the mortality stopped. In the present report, a high mortality rate due to false gid in a sheep herd was described. The prevention and control of the disease are important because of economic losses and the possibility of transmission to the human.
