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

“…O estômago é composto por uma parte glandular onde ocorre os mecanismos protetores e aglandular que não possui autoproteção e por isso esta mais exposta à acidez. Esse órgão raramente se esvazia por inteiro e o trânsito normal do conteúdo gástrico aos outros compartimentos é estimulado pela ingestão de alimento (ARANZALES et al, 2013).…”

Novos temas foram desenvolvidos por alunos das turmas 2022 e 2023 do curso de graduação em zootecnia da Faculdade de Zootecnia e Engenharia de Alimentos da Universidade de São Paulo, com revisões de literatura atuais que trazem uma visão de temáticas zootécnicas dos primórdios até hoje em dia e com enfoque na sustentabilidade. Nesta coletânea temos revisões das principais espécies de interesse zootécnico, com foco em produção e melhoramento genético, nutrição, bem-estar, tecnologia e biotecnologia, entre outras áreas.

“…The first line of defense of the gastric mucosa is the muco-bicarbonate-phospholipid barrier. Along with the property of rapid epithelialization of the mucosa, even with these protective factors, this is an area in which around 20% of gastric ulcers occur (Aranzales and Alves, 2013).…”

We evaluated 28 horses from a squad applied in public safety in Paraná (Brazil), in order to check the incidence of gastric ulcers and its correlation with mounted policing activity, considering the initial and maintenance training to which such animals are submitted. Horses were divided in two groups, one named control with 14 individuals, used in policing community activities, and the 14 others named as target group, these were used in restoration and maintenance of public order. Both groups have differentiated maintenance training protocols, and all had been evaluated for fecal occult blood, clinical evaluation, gastroscopy and histopathological. There were no significant changes that proved the development of gastric ulcers in horses used in public safety due to initial and maintenance training, and the main factor for prevention was the diversified diet with emphasis in hayed alfalfa.
