Safety and efficacy of Lucilia cuprina maggots on treating an induced infected wound in Wistar rats.

Infection is one of the main complications that hinder wound healing. Currently, antibiotic-resistant bacteria, such as Methicilin-resistant Staphylococcus aureus (MRSA), are a concern worldwide for both humans and animals. Maggot therapy is re-emerging as an alternative to intractable wounds and may be an option to the traditional antibiotic treatment.

Muscular and collagenous cerebellar choristoma in a dog.

A 10-yr-old female mixed-breed dog presented with lateral recumbence, vocalization, positional vertical nystagmus, divergent strabismus, anisocoria, and status epilepticus. The clinical condition evolved to stupor and ultimately, death.

Natural Occurring Muscular Sarcocysts in Urban Domestic Cats (Felis catus) Without Sarcocystis-Associated Disease.

Purpose: Despite of classically acting as definitive hosts of different Sarcocystis species, domestic cats have been pointed out as possible intermediate hosts of S. neurona and S. felis.

Leptospira interrogans infection of southern tamanduas (Tamandua tetradactyla, Linnaeus, 1758) in Brazil.

Leptospirosis is a zoonotic disease of global importance caused by an obligate aerobic spirochaete that infects a wide variety of domestic and wild animals. Natural hosts are asymptomatic or show moderate signs of the disease. Accidental hosts develop a severe, often lethal, form of the disease.

Bovine upper alimentary squamous cell carcinoma associated with bracken fern poisoning: Clinical-pathological aspects and etiopathogenesis of 100 cases.

Upper digestive tract (UDT) cancer is rare in cattle, however in Southern Brazil, the UDT squamous cell carcinomas (SCCs) are relatively common and have been associated with bracken fern consumption and the presence of papillomas. Although a theory of pathogenesis considers bovine papillomavirus type 4 (BPV-4) as a cofactor in the development of these SCCs, some aspects of the etiopathogenesis of this disease need to be more investigated. In fact, detection of BPV-4 in UDT papillomas is scarce in other regions of the world and has not been performed in Brazil.

Cutaneous, respiratory and hepatic aspergillosis in Brazilian white Pekin mallards (Anas platyrhynchos).

Aspergillosis is one of the most frequent mycosis affecting avian species. Here is reported an outbreak of aspergillosis affecting 60-day-old white Pekin mallards (Anas platyrhynchos). About 10% of animals in a lot of 200 mallards from a commercial husbandry presented respiratory disorders and skin lesions at slaughter.

Hepatic hemosiderosis in red-spectacled Amazons (Amazona pretrei) and correlation with nutritional aspects.

Alimentary habits of free-living Psittaciformes vary significantly among different species. Amazona pretrei is under risk of extinction and has very specific free-living dietary habits, which are based on Paraná pine seeds. Hemosiderosis is a pathologic process characterized by intracellular accumulation of iron without other evident lesions.
