A 3-month-old Hereford heifer calf was presented for lethargy. Blood gas analysis and plasma biochemical testing revealed severe metabolic acidosis, azotemia, hyponatremia, hyperchloremia, and normal anion gap. Results of a urinalysis were consistent with acute tubular necrosis with inadequate acidification of urine based on the degree of acidemia. Salmonella enterica serovar agona was cultured from both urine and feces. The calf was treated with intravenous polyionic fluids, bicarbonate, and antimicrobials. Acidosis and azotemia resolved, and 4 months following initial presentation the heifer was clinically normal.

A retrospective description of blood and urine alterations in 386 male cats with urethral obstruction in Botucatu, São Paulo, Brazil.
Open Vet J
November 2024
Department of Veterinary Clinics, School of Veterinary Medicine and Animal Science, São Paulo State University (Unesp), Botucatu, Brazil.
Background: Urinary retention in obstructed male cats leads to changes in blood and urine compounds, which, combined with the time of obstruction, are linked to the worsening of the animal's clinical status.
Aim: This study aimed to describe the primary laboratory changes in male cats with urethral obstruction (UO).
Methods: Medical records of 386 male cats diagnosed with UO and treated at the Veterinary Teaching Hospital of the Faculty of Veterinary Medicine and Zootechnics (FMVZ), UNESP-Botucatu, between 2010 and 2020 were reviewed.

Poisoning is often suspected to be the origin of disease in South American camelids (SACs) by owners, but only in a few cases this assumption can be confirmed. In small ruminants, rhododendron poisoning is a common emergency for livestock veterinarians. However, this condition has rarely been reported in SACs so far.

Department of Farm Animals, Vetsuisse Faculty, University of Zurich, Winterthurerstrasse 260, Zurich, CH-8057, Switzerland.
Article Synopsis
- Intestinal strangulation in cows causes serious obstruction due to constriction from tissue or vessels, and a study observed clinical signs in 60 affected cows.
- Common symptoms included signs of pain, colic, and various digestive issues like reduced motility and faecal output, with serious laboratory findings such as hypokalaemia and acidosis.
- Treatment mostly involved surgical intervention (right flank laparotomy), leading to an 81.7% discharge rate, indicating a generally positive outcome for most cases.
Fanconi syndrome with hepatorenal karyomegaly in a young Sphynx cat.
JFMS Open Rep
October 2023
Department of Clinical Sciences, Colorado State University, Fort Collins, CO, USA.
Case Summary: A 3-year-old male neutered Sphynx cat was referred for history of chronically increased liver enzymes and lower urinary tract signs that were first reported when the cat was 5 months old. Urine metabolic profile revealed increased amino aciduria and glucosuria despite normoglycemia, suggesting Fanconi syndrome. Urine sodium dodecyl sulfate-polyacrylamide gel electrophoresis revealed a banding pattern suggestive of primary tubular damage.

Background: Anaemia is a common condition in alpacas and attributable to a variety of causes. Severe anaemia with a packed cell volume (PCV) less than 10% is frequently diagnosed, usually due to blood loss resulting from haemonchosis. Many South American camelids (SACs) also suffer from gastric ulcers, which are often associated with anaemia in other species.
