Abstract

Cowpox virus is considered to be a re-emerging zoonotic pathogen and a public health threat due to increasing numbers of cases in humans and animals in Europe over the past decade, including within the United Kingdom (UK). We present epidemiological data and diagnostic features of 27 recent, naturally occurring cowpox cases in zoo and wild animals across the UK, including the first reports of cowpox in two snow leopards (Panthera uncia), a Bengal tiger (Panthera tigris tigris), three Chilean pudus (Pudu puda), a Malayan tapir (Tapirus indicus) and a Eurasian otter (Lutra lutra), and the first reports of Orthopoxvirus infection in a lar gibbon (Hylobates lar), a Southern tamandua (Tamandua tetradactyla) and an aardvark (Orycteropus afer). This study provides a detailed overview of cowpox infections in a wide range of non-domestic animal species, presents a range of methods for diagnosis and demonstrates the value of retrospective analysis of pathology surveillance in revealing epidemiological links.

Effects of intranasal maropitant on clinical signs of naturally acquired upper respiratory disease in shelter cats.
There was no significant difference in clinical improvement score between the maropitant treatment and control groups for conjunctivitis, blepharospasm, ocular discharge, nasal discharge, or total disease severity after 7 days.

The 4 prokinetic drugs metoclopramide, cisapride, pyridostigmine, and capromorelin do not increase fecal output or food intake in healthy New Zealand rabbits (Oryctolagus cuniculus).
Every day, rabbits produced a median of 75 g (range, 9 to 145 g) of feces, 226 fecal pellets (range, 12 to 412 pellets), and 151 mL (range, 5 to 420 mL) of urine. Metoclopramide, cisapride, pyridostigmine, and capromorelin had no effect on fecal production (both weight and number of pellets), food intake, urine production, or water intake compared to placebo at 24, 48, or 72 hours after administration.

Canine distemper outbreak and laryngeal paralysis in captive tigers (Panthera tigris).
All suspected and confirmed cases of CDV infections were significantly associated with laryngeal inflammation, which developed into paralysis in almost 50% of cases. Altogether, 50% of all tiger cases with chronic infection developed stridor at 314 days after virus infection. Therefore, laryngeal paralysis may result from CDV infection and degeneration, potentially affecting the peripheral and central nervous systems. This condition could pose a life-threatening risk to tigers.

Efficacy, safety and interval from end of treatment to estrus in cats treated with an ultra-low dose megestrol acetate protocol for suppression of reproductive activity.
Twenty-eight queens were treated orally with 11.5 µg/kg/day of megestrol acetate (MA) for one to six months. MA suppressed reproductive function effectively in 27/28 queens. Transient mammary and uterine hyperplasia were detected in four (14 %) and three (11 %) queens, respectively, treated for more than four months, without associated clinical signs. Significant but reversible weight gain was observed in 85 % of the animals. The resumption of cyclicity occurred on average 6 weeks after the end of treatment but was influenced by the duration of treatment and seasonality.

Owner satisfaction and prognosis for return to work after pancarpal arthrodesis in working dogs in the United Kingdom: a retrospective study (2011-2020).
50% (5/10) owners stated their dog could perform normal duties; 4/10 (40%) could perform most duties with some allowances. 80% (8/10) owners rated the level of post-operative lameness as unaffected with a normal gait. 90% (9/10) owners were either very satisfied or satisfied with the outcome of the procedure, and 90% owners stated the financial investment was worthwhile.
