“…In agreement with our findings, high prevalences were found in England (63-100 %; Coles and Pearson 2000), Australia (81 %; Bucknell et al 1995), and Saudi Arabia (86.6 %; Anazi and Alyousif 2011). Conversely, lower prevalences were found in the most part of European Countries, such as Swisse (65 %; Brocard and Pfister 1991), France (2-34 %; Bernard et al 1994), Poland (40-47 %;Gawor 1995;Niedźwiedź et al 2013), Sweden (9.9 %; Höglund et al 1997), Belgium (58 %; Agneessens et al 1998), and Germany (2.8 %; Rehbein et al 2013), and in Countries outside Europe, such as the USA (14 %; Lyons et al 2000), Brazil (17-32 %; Sequeira et al 2001;Felix et al 2007), and Turkey (9.8 %; Gökçen et al 2008). Low prevalences of infestation by Gasterophilus spp.…”

“…Low prevalences of infestation by Gasterophilus spp. have been attributed mainly to the current extensive use of antiparasitic drugs, which are highly effective against all Gasterophilus instars (Sweeney 1990;Lyons et al 2000;Sequeira et al 2001;Gökçen et al 2008;Niedźwiedź et al 2013;Rehbein et al 2013).…”

“…Currently, Gasterophilosis has a worldwide distribution, and shows prevalences ranged from 3 to 94 %. However, Gasterophilus species have different distribution in the world (Bucknell et al 2008;Anazi and Alyousif 2011;Niedźwiedź et al 2013;Rehbein et al 2013). In fact, only Gasterophilus intestinalis and Gasterophilus nasalis are distributed worldwide, whereas the other Gasterophilus species have been reported in more limited areas of the world.…”

Gasterophilus larvae are common obligate parasites of the digestive tract of the equids. Horses become infected with this parasite by ingesting the larvae hatched from eggs laid by the female flies. In this study carried out monthly, we (i) counted the Gasterophilus eggs deposited by female flies on the coat of 30 grazing horses, (ii) counted and identified the Gasterophilus larvae retrieved from the digestive tract of 128 slaughtered horses, and (iii) compared these results to meteorological data. Eggs were deposited on all monitored horses, and were present from October to January and from May to September, whereas they were absent from February to April. The number of laid eggs was significantly different between the months, body regions, genders, and age classes (p < 0.05). Larvae were recovered in 112 (87.5%) horses, and 6 species of Gasterophilus were identified. The prevailing species were Gasterophilus intestinalis (recovered in 110 horses; 85.9%) and Gasterophilus nasalis (69 horses; 53.9 %), recovered in all months. Gasterophilus inermis (5 horses; 3.9%), Gasterophilus pecorum (3 horses; 2.3%), Gasterophilus haemorrhoidalis (3 horses; 2.3%)¸ and Gasterophilus meridionalis (2 horses; 1.6%) larvae were also found. Significant differences were found among monthly larval burdens for both Gasterophilus spp. and G. intestinalis (p < 0.05), but not for G. nasalis (p > 0.05). Larval burdens and prevalences did not differed significantly between both genders and age classes (p > 0.05). Monthly eggs and larvae trends were not significantly correlated (p > 0.05). With regard to the meteorological variables, minimum air temperature was significantly correlated with the eggs trend (rho = 1.000; p < 0.001) and maximum air temperature with the Gasterophilus spp. (rho = 0.972; p < 0.001) and G. intestinalis (rho = 0.972; p < 0.001) larvae trends. In addition, the number of hours with a temperature below +10 °C was significantly correlated with G. intestinalis larvae trend (rho = 0.602; p < 0.05). Our findings confirmed that in Sardinia, Gasterophilosis is an important parasitosis in the horses, and it needs more attention and extensive and/or correct treatment to reduce its prevalence.

“…Para la caracterización de las úlceras gástricas, éstas fueron clasificadas según cantidad y severidad, utilizando el protocolo descrito por MacAllister et al (1997) 26 , graduadas de 0 a 4, en la cual el grado 0 es una mucosa normal y sin lesiones, el grado 1 con presencia de 1 a 2 lesiones focalizadas, el grado 2 con presencia de 3 a 5 lesiones localizadas, el grado 3 de 6 a 10 lesiones focalizadas y el grado 4 más de 10 lesiones grandes y difusas. y para asociar la presencia de larvas según número y ubicación gástrica se utilizó en protocolo propuesto por Niedzwiedz et al (2013) 32 , clasificadas en 3 grupos, menor de 30 larvas, de 30 a 60 larvas y mayor de 60 larvas. Para el análisis estadístico se estimaron frecuencias y la prueba de Chí cuadrado, con el objeto de determinar si la presencia y el grado de úlceras escamosas secundarias eran dependientes del sexo, la edad y del número de larvas presentes.…”

“…Después de la ingestión, el primer estadio larval (L1) pasa a través del tracto digestivo, donde permanecerán unidos a la mucosa gástrica hasta por 10 a 12 meses y evolucionar hasta el tercer estadio (L3). Las especies de Gasterophilus difieren también en su color y en la localización final de la larva en el tracto digestivo; es así como larvas (L3) de G. intestinalis son de color rojo y se adhieren a la mucosa escamosa del estómago, mientras que larvas (L3) de G. nasalis son de color amarillo y se ubican en la mucosa de la región antropilórica y porción proximal del duodeno 7,32,33,39 .…”

Cardona JA et al. Ocurrencia de miasis cavitaria equina (Gasterophilus Spp) y su relación con las úlceras gástricas ¤ Para citar este artículo: Cardona JÁ, Álvarez A, Paredes E. Ocurrencia de miasis cavitaria equina (Gasterophilus Spp) y su relación con las úlceras gástricas secundarias en la mucosa escamosa en AbstractThe aim of this study was to determine the ocurrence of equine cavitary myiasis (Gasterophilus spp) in the CholChol slaughtering house in Temuco, Chile and its relation with the presentation of secondary gastric ulcers in the non-glandular squamous mucosa of the horses' (Equus caballus) stomachs. Of 240 stomachs evaluated post mortem, 145 were selected and characterized as positive to gasterophilosis (60.4%), of which 75 were males (20 stallions and 55 geldings) and 70 were mares, with ages ranging from 1 to 16 years. Every stomach was evaluated, characterized and photographed post mortem. Information about sex, age, location of the Gasterophilus larvae, presence and degree of ulceration of the squamous mucosa, were recorded in the respective forms and posteriorly digitalized. Global analysis of the location of larvae in the stomach of horses positive to gasterophilosis, established that 91.7% were located in the glandular mucosa, while 8.3% were located in the squamous mucosa. In the stomachs with presence of larvae in the antral/piloric regions of the glandular mucosa, 87.6% had secondary ulcers in the nonglandular squamous mucosa, due to the increase in the gastric fill line following alterations in gastric emptying, of which 69% were classified in categories 3 to 4 with a number of larvae higher tan 30, while 18.6% were found in categories 1 or 2 with less than 30 larvae per site. Regarding the location of larvae in the squamous mucosa, 8.3% of the stomachs showed primary mechanic ulcers, all classified between grades 1 and 2. Of all the animals evaluated, 62.1% had more tan 60 larvae, of which 60.1% had grade 3 or 4 secondary squamous ulcers, 15.9% had between 30 and 60 larvae per site, and 14.5% had less than 30 larvae per site. The study showed significant statistical dependence (p<0.05) between the number of larvae located in the glandular mucosa and the degree of severity of the secondary gastric ulcers in the squamous mucosa. Concluding, a high ocurrence of cavitary gastric myiasis was observed in slaughtering horses in the south of Chile, with squamous ulcers secondary to abnormal gastric emptying being the
