“…The results of our study indicated that oestrosis prevalence was higher among sheep than goats (P < 0.001). While this result was similar with most of the studies investigating sheep and goats together (Alem et al, 2010;Papadopoulos et al, 2010;Gebremedhin, 2011;Negm-Eldin et al, 2015), it was reported to be higher in goats (76%) than sheep (38%) in a study from Greece (Papadopoulos et al, 2010).

“…When the results of our study were compared with those of the previous studies from Turkey, the prevalence of the disease in sheep were found to be higher than that reported from Kars (40.3%) (Arslan et al, 2009), Konya (59%) (Uslu and Dik, 2006), Sanliurfa (36.7%) (Gökcen and Sevgili, 2004), Nigde (22.52%) (Karatepe et al, 2014). When compared with the studies from the world, while it was higher than in Libya (51.66%) (Negm-Eldin et al, 2015), Greece (48.6%) (Papadopoulos et al, 2006), Saudi Arabia (53.5%) (Hanan, 2013) and Brazil (13.7%) (Silva et al, 2013), it was lower than in Central Oramina Ethipia (94.6%) (Alem et al, 2010) and Italy (91%) (Scala et al, 2001). The ratios are similar with those from Spain (71.1% and 75.9%) (Alcaide et al, 2003;Gracia et al, 2010), Morocco and Greece (69.2% and 75.9%) (Pandey and Ouhelli, 1984;Papadopoulos et al, 2010).…”

“…Various studies worldwide have reported prevalence of oestrosis between 13.7-94.6% in sheep, 17.9-88.4% in goats (Alem et al, 2010;Papadopoulos et al, 2010;Silva et al, 2013). No studies investigating the prevalence of the disease in goats in Turkey have been encountered however it was found as 22.52-59% in sheep in studies conducted in various regions (Gökcen and Sevgili, 2004;Uslu and Dik, 2006;Arslan et al, 2009;Karatepe et al, 2014).…”

Oestrosis is a parasitic disease which is prevalent among sheep and goats in Mediterranean region. Slaughter house surveys to determine the prevalence and intensity of infestation by Oestrus ovis Linnaeus (Diptera: Oestridae) in sheep and goats, were conducted monthly for one year in south-eastern region of Turkey. A total of 804 heads belonging to 724 sheep and 80 goats were examined for Oestrus ovis larvae between May 2014 and April 2015. 72.75% of sheep heads and 50% of goat heads were seen to be infested with Oestrus ovis larvae. Of a total of 4723 larvae found in sheep heads, 2245 were detected to be first instars larva, 1231 second instars larva, 1247 third instars larva. Of a total of 259 larvae detected in goats, 150 were first instars larva, 79 second instars larva, 30 third instars larva. The mean of larval burden per infested animal was significantly higher in sheep (8.8±5.9) than in goat (6.5±5.0) (P < 0.05). Monthly distribution of first, second and third instars larvae indicate that adult flies are active between April and end of September, first instars larvae enter hypobiotic period in October. In conclusion, it was revealed that to use an effective drug against Oestrus ovis that will be done during reproductive period of flies should start in April and continue until the end of summer due to high rates of oestrosis, parasite treatment that will be done when reproductive period ends should be done in October and November in the southeast part of Turkey.

“…As larvas encontradas na traqueia, possivelmente migraram para o local após a morte do animal. Neste estudo, os pequenos ruminantes demonstraram sinais clínicos considerados típicos da oestrose (Dorchies & Alzieu 1997, Scala et al 2001, Alcaide et al 2005, Jacquiet et al 2005, Alem et al 2010, Angulo-Valadez et al 2011, Schenkel et al 2012, bem como as lesões mais frequentes relatadas na enfermidade (Tabouret et al 2003, Alem et al 2010, Angulo-Valadez et al 2011. Apesar da oestrose em pequenos ruminantes no DF e Estado de Goiás não estar associada com a causa da morte na maioria dos animais dos surtos investigados, pode haver altos índices de mortalidade quando ocorre concomitantemente com outras doenças (Schenkel et.…”

showed mycotic or oomicotic granulomatous rhinitis and 22 animals (22/538, 4.08%) presented oestrosis diagnosis, affecting 86.36% of sheep and 13.64% of goats. The pyogranulomatous rhinitis in sheep occurred in flooded areas with abundant plant material decomposing. Rhinofacial pythiosis infection in animals showed as major changes swelling in the nasal region due to extensive granulomatous lesions associated with tissue necrosis, characterized by numerous macrophages and polymorphonuclear cells surrounding necrotic centers containing the agent surrounded by Splendore-Hoeppli reaction. Sheep with conidiobolomycosis showed extensive areas of necrosis and pyogranulomatous inflammation associated with fungal hyphae, localized in the nasopharynx and also in peribulbar region and exophthalmia. Most animals with oestrosis showed no significant clinical and pathological changes, even with the presence of larvae mainly in the sinuses and nasal turbinates, trachea and paranasal sinus. The importance of such diseases is still unknown in the region, and the knowledge of the clinical-pathological and epidemiological conditions is of great relevance for the diagnosis, control and prevention to avoid the expansion and losses to livestock.

Pesq. Vet. Bras. 32(8):754-756, agosto 2012 754 RESUMO.-Oestrus ovis é um parasito cosmopolita que pode acometer ovinos e caprinos. A fase parasitária inicia--se após as fêmeas adultas depositarem suas larvas nas narinas dos hospedeiros. O objetivo deste trabalho foi de descrever os aspectos clínicos, epidemiológicos, macroscópicos e microscópicos de um surto de oestrose em ovinos no estado de Mato Grosso. Os principais sinais clínicos observados foram espirros e descarga nasal. Macroscopicamente havia hiperemia e edema da mucosa nasal. Os achados microscópicos eram caracterizados por hiperemia e edema moderado a acentuado e difuso, associados a inϐil-trado leve a moderado predominante de mastócitos e eosinóϐilos na submucosa. Embora a doença fosse observada em um grande número de animais a mortalidade observada nos surtos ocorreu devido à infestação por Haemonchus contortus e pneumonia. INTRODUÇÃOAs doenças causadas por parasitos são importantes causas de prejuízos na produção nacional de ovinos (Rissi et al. 2010). A oestrose (bicho da cabeça, falso torneio) é uma doença que pode acometer ovinos e é causada pela infestação de larvas de Oestrus ovis na cavidade nasal e seios nasais desses animais (Tabouret et al. 2001). As fêmeas adultas de O. ovis fazem a deposição de larvas nas narinas dos animais e essas larvas dirigem-se rapidamente aos cornetos nasais e frontais, completando o período de parasitismo entre 1 e 9 meses (Yilma & Dorchies 1991) dependendo das condições climáticas. As moscas adultas perturbam os animais que tentam se livrar delas sacudindo a cabeça, esfregando--a contra objetos ou outros animais, ou se coçando e batendo com os membros anteriores. Os animais apresentam respiração diϐicultosa e ruidosa. No seio frontal e meato dos cornetos nasais a larva causa irritação da mucosa levando a rinite catarral com espirros e/ou corrimento nasal purulento (Taylor et al. 2011).Apesar de O. ovis ser considerada cosmopolita, ocorrendo em todas as regiões do globo onde existam ovinos e caprinos (Ribeiro 2007), não existe registro na literatura da ocorrência dessa doença no Estado de Mato Grosso. O objetivo deste trabalho foi descrever aspectos clínicos, epidemiológicos, macroscópicos e microscópicos de um surto de oestrose em ovinos em Mato Grosso.
