Resumen
La hidropesía fetal o edema congénito, se caracteriza por una excesiva acumulación de fluidos subcutáneos con o sin presencia de efusión torácica y abdominal. Se estudiaron 34 hembras (13 de bulldog inglés, 9 de Bulldog francés y 12 American Bully) con un total de 173 cachorros nacidos. Todas las hembras fueron monitoreadas desde el servicio y fueron sometidas a cesárea programada 56 días después del primer día del diestro citológico. En 3 camadas de Bulldog Francés, 5 camadas de Bulldog Inglés y 2 camadas de American Bully se registraron nacimientos de cachorros con anasarca. Los grados de anasarca observados oscilaron desde grados severos hasta leves. Todos los cachorros nacidos con anasarca murieron dentro de las 2 hs de nacidos. Nuestros resultados sugieren que el factor hereditario se encuentra presente. Sin embargo, se necesitan más estudios para clarificar la heredabilidad del problema mediante la identificación de los genes involucrados en las líneas familiares que producen cachorros con anasarca.
Fetal hydrops or congenital edema is characterized by excessive accumulation of subcutaneous fluids with or without thoracic and abdominal effusion. Thirty-four females (13 English Bulldogs, 9 French Bulldogs, and 12 American Bullies) with a total of 173 puppies born were studied. All females were monitored from the breeding service and underwent scheduled cesarean section 56 days after the first day of cytological diestrus. In 3 litters of French Bulldogs, 5 litters of English Bulldogs, and 2 litters of American Bullies, puppies with anasarca were born. The observed degrees of anasarca ranged from severe to mild. All puppies born with anasarca died within 2 hours of birth. Our results suggest the presence of a hereditary factor. However, further studies are needed to clarify the heritability of the problem by identifying the genes involved in the breeding lines that produce puppies with anasarca.
