Perihepatic abscess associated with vagal indigestion syndrome in cattle: retrospective study

Le résumé fourni par la source

Abstract Vagal indigestion (VI) is a syndrome characterized by changes in the motility of the forestomach and abomasum, which occurs in the event of dysfunctions in the vagus nerve. Several inflammatory conditions are associated with nerve injury, however, the relationship between perihepatic abscesses and this syndrome is poorly documented. Therefore, a retrospective study of the clinical, laboratory, ultrasound and anatomopathological findings of 15 cattle presented with VI due to perihepatic abscess was carried out. Samples from the liver abscesses of three cattle were sent for bacteriological analysis. All were over 24 months old, were dairy cows in the productive phase (86.67%, 13/15) and raised in a semi-intensive system (73.34%, 15/11). The main clinical findings were dehydration, ruminal tympania, ruminal hypermotility and scanty feces. Laboratory tests revealed leukocytosis due to neutrophilia, with a regenerative shift to the left and elevated chloride content in the ruminal fluid. Ultrasonography revealed reticular hypermotility, ruminal distension and large abscesses adjacent to the left hepatic lobe, which were confirmed by pathological examination. Bacteriological evaluation identified Staphylococcus aureus, Enterococcus faecalis and Providencia stuartii. It is concluded that among the causes of IV syndrome, the presence of perihepatic abscesses should be considered when establishing the diagnosis of the disease.
