Characterization of ovine gammaherpesvirus 2 in a goat by nanoplate digital PCR and other diagnostic methods.

The Macavirus, ovine gammaherpesvirus 2 (OvGHV2), is the cause of sheep-associated malignant catarrhal fever (SA-MCF). Although SA-MCF occurs in a wide range of mammalian hosts, there are few descriptions of this disease and/or infection in goats. This report describes the findings observed in a goat that was infected by OvGHV2 and adds to the rare description of this infection in this animal species.

Effects of two oral electrolyte solutions in healthy newborn lambs.

This study aimed to evaluate the effects of two oral electrolyte solutions (OES), commercialized for the hydration of calves, on the water, electrolyte, and acid-base balance of newborn lambs. Twenty healthy crossbred Santa Inês lambs, 10 days old, 4-5 kg of body weight (BW), and fed on mother's milk, were included. The OES tested were slightly hyposmolar (OES 1: 279 mOsm/L; and OES 2: 283 mOsm/L) and had an alkalizing potential with an effective strong ion difference (SID) of 76 mmol/L (OES 1) and 58 mmol/L (OES 2).

Enteral hydration in cows: Comparison between continuous flow and bolus administration.

Background: Enteral hydration in cattle is most commonly performed as a bolus (B) via the ororuminal route, although continuous flow (CF) administration via the nasoesophageal route represents a viable alternative. Currently, no study has compared the effectiveness of these two methods. This study aimed to compare the efficiency of enteral hydration using CF and B to correct water, electrolyte and acid-base imbalances in cows.

Ovine gammaherpesvirus-2 infection associated with chronic interstitial pneumonia in a sheep.

Sheep Associated-Malignant Catarrhal Fever (SA-MCF) is severe, frequently lethal, lymphoproliferative disease predominantly of ruminants, that is caused by ovine gammaherpesvirus-2 (OvHV-2), a member of the MCF virus (MCFV) complex. However, SA-MCF in sheep is a rare entity with few demonstrations of natural diseases worldwide. This report documents the clinical, radiographical, pathological, immunohistochemical, and molecular findings of SA-MCF in a sheep.

Evaluation of changes in microbiota after fecal microbiota transplantation in 6 diarrheic horses.

The purpose of this study was to characterize the fecal microbiota of horses with acute and chronic diarrhea before and after fecal microbiota transplantation (FMT). Six client-owned horses with acute and chronic diarrhea received FMT from 2 healthy donor horses. Microbiota analysis using next-generation sequencing was performed on fecal samples collected before and 2 and 7 d after FMT.

Diphtheric aspergillosis tracheitis with gastrointestinal dissemination secondary to viral infections in a dairy calf.

Diphtheric aspergillosis tracheitis is an uncommon syndrome described in human pathology, usually associated with immunosuppression in the affected individuals. Interestingly, no comparative/equivalent cases were found in domestic animals. This report describes the pathological and mycological findings associated with diphtheric aspergillosis tracheitis in an immunocompromised calf.
