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.

[Disease Caused by Filoviruses: An Update].
The Marburg and Ebola viruses belong to the Filoviridae family and are known to cause emerging zoonotic diseases. These viruses have a high case fatality rate and are easily transmissible from person to person, which makes them capable of triggering outbreaks, including in non-endemic regions, and are also considered agents of bioterrorism. This review aims to improve clinical knowledge and the approach to suspected cases of FD. Improved surveillance and preparedness for potential global outbreaks are essential measures to effectively respond to these public health threats and to ensure that healthcare professionals are well-informed and prepared to deal with these diseases.

Development of a dog owner caregiving style scale (Lincoln Owner Caregiving Questionnaire, LOCQ) and its relationship with behaviour problems in dogs
Compared to owners of dogs without behaviour problems, owners with high scores for the Disorganised caregiving style predicted dogs with separation related problems or with more than one behaviour problem, owners with high Avoidant caregiving style scores predicted dogs with Fear, and owners with high scores for both Disorganised and Avoidant caregiving styles predicted dogs with Aggressivity problems.

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.

Companion animal veterinary personnel have occupational risk for tularemia and One Health role for tularemia prevention in Kansas.
Forty-three percent (47 of 109) of veterinarians reported diagnosing tularemia in cats and 13% (14 of 109) in dogs. Seven percent (8 of 109) of veterinarians reported having had tularemia. When performing procedures with a high risk of exposure, such as lancing abscesses in tularemia suspects, glove use was 100% but additional personal protective equipment was inconsistent, including eye protection (70%) and surgical face mask (59%).

Owner survey suggests cats may be undertreated for pain compared to dogs after an elective ovariohysterectomy or orchiectomy.
Analgesics were prescribed for 19 of 162 (12%) pets: 14 of 88 (16%) dogs and 5 of 74 (6.7%) cats. There was no difference in the prescription of analgesics between dogs and cats after ovariohysterectomy or orchiectomy. 15 of 19 owners reported their compliance in administering analgesics at 78.9%. Owners' subjective assessments showed that 24 of 86 (28%) dogs and 12 of 68 (17%) cats appeared painful at home.
