Characterization of the citológical profile of the vaginal mucous during the estral cycle in the Santa Inês sheep

The objective of the work was to characterize the cycle of the vaginal epithelium of sheep of the Santa Inês breed, through a cytological study. Vaginal mucosal samples were taken from 10 sexually mature ewes, from the first day of estrus and for 18 days. The samples were stained with Papanicolaou a...

Vaginal mucosal samples were taken from 10 sexually mature ewes, from the first day of estrus and for 18 days. The samples were stained with Papanicolaou and observed under an optical microscope. Parabasal, de epintermediate, superficial intermediate, and superficial cells were recognized. The parabasal cells presented a rounded shape, little cytoplasm, and a large nucleus, they were scarce. The deep intermediate ones with rounded edges, more abundant cytoplasm, and smaller nuclei. They were observed in greater quantity than the parabasal ones. The superficial intermediate ones were the most abundant through out the study and the one swith the largest diameter. They presented a polygonal shape and a smaller nucleus. The identification of two types of intermediate cells coincides with works on dogs, cows, and alpacas, while other works describe a single type. Superficial cells were divided into two subtypes, A, with a polygonal shape and piknotic nucleus, and B, with a smaller and intensely acidophilic cytoplasm and pyknotic nucleus. The latter has not been found so far in other works with sheep. Changes in cell types did not accurately reflect the phase of the estrous cycle. El objetivo de trabajo fue caracterizar el ciclo del epitelio vaginal de ovejas de raza Santa Inês, mediante estudio citológico. Se tomaron muestras de la mucosa vaginal a 10 borregas sexualmente maduras, desde el primer día de celo y por 18 días. Las muestras se colorearon con Papanicolaou y se observaron en microscopio óptico. Se reconocieron células parabasales, intermedias profundas, intermedias superficiales y superficiales. Las células parabasales presentaron forma redondeada, citoplasma escaso y núcleo grande, fueron escasas. Las intermedias profundas de bordes redondeados, citoplasma más abundante y núcleo menor. Se observaron en mayor cantidad que las parabasales. Las intermedias superficiales fueron las más abundantes en todo el estudio y las de mayor diámetro. Presentaron forma poligonal y núcleo más pequeño. La identificación de dos tipos de célula intermedia, coincide con trabajos en perras, vacas y alpacas, en tanto otros trabajos describen un solo tipo. Las células superficiales se dividieron en dos subtipos, el A, con forma poligonal y núcleo picnótico y el B, con citoplasma más pequeño e intensamente acidófilo y núcleo picnótico. Este último no se encontró hasta el momento en otros trabajos con ovejas. Las modificaciones de los tipos celulares no reflejaron de manera precisa la fase del ciclo estral.
