Ultrasound findings in 34 newborn foals with uroperitoneum.

Background: Uroperitoneum is a typical disease of the newborn foal, which occurs rarely but regularly. Ultrasonography is considered the most important imaging method for diagnosing this disease. Thus far, only one older case series comprising 31 foals suffering from uroperitoneum has systematically listed results of ultrasound examinations.

Induction of NETosis in ovine colostral PMN upon exposure to tachyzoites.

Colostrum is one of the most important factors influencing the health and development of mammalian neonates. It is well-established that leukocytes, including polymorphonuclear neutrophils (PMN), migrate from the mother to the infant via colostrum uptake. In this study, for the first time, we studied the ability of ovine colostral-derived PMN to extrude neutrophil extracellular traps (NETs) against the abortive apicomplexan parasite .

Neospora caninum-induced NETosis in canine colostral polymorphonuclear neutrophils.

Neospora caninum represents an obligate intracellular apicomplexan parasite of the family Sarcocystidae causing severe reproductive disorders in cattle, small ruminants, wild animals and canids worldwide. Neutrophil extracellular traps (NETs) were recently described as effective host defense mechanism of polymorphonuclear neutrophils (PMN) derived from cattle, dogs, goats and dolphins against N. caninum tachyzoites.

[Occurrence and importance of colostral leukocytes].

Leukocytes have been identified as a physiological component of colostrum in numerous animal species. In each of the examined species, they have been shown to occur in a typical amount exhibiting slight differences in the composition of leukocyte subpopulations. According to previous opinions, colostral leukocytes merely accidentally transfer from blood to milk or represent a sign of mastitis.
