Ulcerative balanoposthitis (UB) is a venereal disease which has frequently been diagnosed in sheep in South Africa (SA) since 1979, with no conclusive causative agent or treatment available. The purpose of this study was to determine whether ovine herpesvirus 2 (OvHV-2) can be used as biomarker to diagnose the early onset of UB in sheep flocks in SA. The study made use of 10 healthy Dohne Merino rams, two healthy Dorper rams, and 10 UB-affected Dorper rams. Smegma-, blood-, nasal swab- and sheath swab samples, respectively, were collected from all rams, and subjected to a single-tube hemi-nested PCR analysis to determine OvHV-2 status of all the sample types collected. The prevalence of OvHV-2 in all 22 animals was 22.75%, irrespective of breed or health status. The detection rate of OvHV-2 was 33.3% for the 10 UB-positive animals, and 16.7% for the 12 UB-negative animals. In blood, OvHV-2had a 4.54% detection rate, 8.33% in smegma, 13.64% in nasal samples, and a 0% detection in penile swabs. This study found nosignificant co-occurrence of UB and OvHV-2, which indicates that OvHV-2 cannot be considered as a biomarker for the early onset of UB or a causative agent of UB.

Many species of vulture are under threat from man-made inventions; this has led to wounded and sick vultures presenting for veterinary treatment and in need of pain management. Following the devastating effect of diclofenac on vultures in South Asia, meloxicam was found to be very safe for vultures, as a treatment as well as through ingestion of meat from treated animals. Many studies investigated the safety of meloxicam, and all found it to be safe up to 2 mg/kg, which was deemed the maximum likely exposure through treated carcasses. All studies exposed the birds either through oral dosing, treated meat or intramuscular administration, no instances of toxicity where recorded and all birds remained healthy. In this case the bird was exposed to a single dose of 2 mg/kg, intravenously, with no signs of toxicity. This appears to be the first recorded instance of accidental intravenous administration of meloxicam in a vulture.

As a newly-minted veterinarian and aspirant pathologist, my first publication reported on an osteosarcoma at the thoracic inlet of a dog (Schröder 1976). The case was noteworthy because it was unusual for an osteosarcoma to originate on the axial skeleton, rather than on one of the long bones. Several years later, now wearing a parasitologist's hat, I have asked myself on numerous occasions if I might have missed an aetiological diagnosis of spirocercosis because I was too fixated on the neoplasm and its location. My only aide memoire is the paper from 1976, according to which I looked for and found metastases in the liver and lungs, but alas, no indication that I had also examined the oesophageal wall carefully.

Current literature most commonly describes the use of the dissociative drug ketamine for the immobilisation of baboons, either on its own or in combination with other drugs such as α-2 agonists or benzodiazepines. Currently, no reversal is available for ketamine, leading to prolonged and often rough recoveries of the animals, especially if high doses of ketamine are used. In this study, the fixed-dose combination of butorphanol, azaperone and medetomidine (BAM) with a low dose of ketamine (K-BAM) was evaluated for immobilisation and recovery parameters of chacma baboons. Fifteen baboons were immobilised and monitored. Actual doses administered: BAM 0.01 ± 0.005 ml/kg (butorphanol 0.31 ± 0.15 mg/kg, azaperone 0.12 ± 0.06 mg/kg, medetomidine 0.12 ± 0.06 mg/kg) and ketamine 2.04 ± 0.22 mg/kg. During immobilisation, heart rate (HR), respiration rate (RR), peripheral oxygen saturation (SpO2), end-tidal carbon dioxide (EtCO2), noninvasive blood pressure (BP) and blood gases were evaluated. Inductions were reached in 3.46 ± 1.36 minutes. Overall, severe hypoxaemia (SpO2: 62 ± 13%; PaO2: 37 ± 10 mmHg) was observed in all baboons as well as elevated EtCO2 (63 ± 9 mmHg) and PaCO2 (63 ± 9 mmHg) values. Other measured parameters stayed within normal ranges. Recoveries were fully reached at 4.8 ± 2.8 minutes after intramuscular injection of the reversal naltrexone and atipamezole. BAM with a low dose of ketamine produced short-term immobilisation, allowing for minor veterinary procedures. The evere hypoxaemia observed in all animals, however, raises serious concerns regarding the safety of this protocol.
