El presente trabajo de investigación tuvo como objetivos determinar las características morfológicas externas de los paramphistómidos mediante el uso del microscopio electrónico y a la vez, las características internas, a través de cortes histológicos. Para tal fin, se colectaron del rumen y retículo de bovinos treinta parásitos, los cuales previo a su identificación macroscópica en el Camal Municipal de Cajamarca fueron mantenidos en solución salina (Cloruro de Sodio 0.9%) y luego trasportados al laboratorio de Patología Veterinaria de la Universidad Nacional de Cajamarca donde, un grupo (15 parásitos) fue fijado mediante el método de Glutaraldehído para realizar microscopía electrónica en el Laboratorio de Patología de la Universidad Nacional Mayor de San Marcos, en el Hospital Nacional Arzobispo Loayza y otro grupo fijado con formol bufferado para cortes histológi...

Palatoschisis is a hereditary teratoma that occurs in cattle, it is a hereditary anomaly that affects the oral cavity due to a bad closure during embryonic development, this malformation can have a negative impact on the animal, affecting its feeding and generating problems such as regurgitation and rhinitis. We report the case of a 2-month-old female bovine that presented a malformation specifically in the hard palate. It was observed that the calf presented palatoschisis, showed difficulty in feeding, as well as rhinitis, symptoms derived from the described anomaly.

Diprosopus is a congenital malformation result, also known as craniofacial duplication, which is widely recognized in humans and there are also reports in many animal species. The objective of this research is to learn about the clinical manifestations and post mortem findings in cattle diprosopus. Female cattle with incomplete cephalic facial cephalic duplication (diprosopus), product of the eighth gestation of a Creole cow with, from the village center of Quidén, district of Paccha, province of Chota, region of Cajamarca, Peru, with extensive production breeding system. The cattle presented two lower jaws with double oral and nasal cavity, two tongues and supernumerary teeth, the vault was double and single neck. It is confirmed that the case described is diprosopus in cattle.
