Disseminated protothecosis caused by Prototheca bovis in two dogs.

Protothecosis is an infectious disease caused by unicellular algae of the genus Prototheca, which are mainly known for causing mastitis in farm animals. However, there are reports of protothecosis in humans and other animals, such as dogs and cats, which develop cutaneous lesions or systemic lesions. Dogs with the systemic form generally develop bloody diarrhoea and blindness and neurological signs may also occur.

Staphylococcus felis C4 exhibits in vitro antimicrobial activity against methicillin-resistant Staphylococcus pseudintermedius in a novel canine skin explant model.

Background: Canine superficial pyoderma is a common bacterial skin infection of dogs, generally caused by Staphylococcus pseudintermedius. The C4 strain of Staphylococcus felis was recently discovered to have strong antimicrobial activity against S. pseudintermedius in mice.

Myosin heavy-chain myopathy in 2 American quarter horses.

A 1.5-year-old American quarter horse gelding (case 1) and an 11-month-old American quarter horse filly (case 2) were presented for acute onset pelvic lameness and lethargy. Case 1 had nasal discharge, while case 2 developed rapid muscle atrophy.

Common superficial and deep cutaneous bacterial infections in domestic animals: A review.

The skin covers the external surface of animals, and it is constantly exposed to and inhabited by different microorganisms, including bacteria. Alterations in the skin barrier allow commensal and/or pathogenic bacteria to proliferate and penetrate deep into the lower layers of the skin. Being the first barrier to the external environment, the skin is prone to injuries, allowing the penetration of microorganisms that may lead to severe deep infections.

Cylicospirura felineus in Puma (Herpailurus yagouaroundi) in southern Brazil - Macroscopic and microscopic aspects.

Parasites of the Cylicospirura genus are known to affect domestic and wild carnivores by causing the formation of nodules within the gastric mucosa and pyloric region of parasitized animals. C. felineus is a specimen of this genus that has been reported in Brazil in animal species such as Leopardus geoffroyi and Puma concolor.

Paraconiothyrium cyclothyrioides, a novel cutaneous fungal pathogen in a dog and a cat.

A dog and a cat presented with pyogranulomatous mycotic pododermatitis. Panfungal PCR and next-generation sequencing identified Paraconiothyrium cyclothyrioides with 100% identity. Paraconiothyrium cyclothyrioides can rarely cause cutaneous infection and systemic disease in immunocompromised humans.

A spontaneous compound odontoma in an adult Sprague Dawley rat (Rattus norvegicus).

Reports of compound odontomas in rats are very rare. A 14-month-old adult male Sprague Dawley rat was found to have a hard mass associated with the caudal aspect of the left mandible. After 2 weeks of observation, the rat was euthanized due to the mass growing significantly in size and the rat losing >20% of its body weight.

Protozoal meningoencephalitis and myelitis in 4 dogs associated with infection.

American trypanosomiasis is caused by the zoonotic protozoa and primarily results in heart disease. Organisms also infect the central nervous system (CNS). The Texas A&M University veterinary teaching hospital archive was searched for dogs with CNS disease with intralesional protozoal amastigotes.

Spontaneous poisoning by Hovenia dulcis in dairy cattle in Southwest Parana, Brazil.

Livestock poisoning by plants is a frequent occurrence which determines severe losses, such as the fall in the milk and meat production, the cost of expensive treatments, the state of immunosuppression, or even the animal's death. Cattle ingest toxic plants only when there is food shortage, when they cannot select what they eat, or when they ingest food for preference, which is the case of Hovenia dulcis fruits, very rich in sucrose. This plant is widely distributed in the southern and southeastern Brazilian regions.
