Reconstruction of large scalp defect in a brown howler monkey (Alouatta guariba clamitans): A case report.

This case report describes different repair techniques used to reconstruct a large scalp defect in a brown howler monkey (Alouatta guariba clamitans) hit by a vehicle. Three reconstructive procedures were performed in two surgical stages. The repair techniques had successful outcomes on the patient's rehabilitation.

Radiographically guided femoral neck osteosynthesis with cannulated compressive titanium screw and anti-rotational component in a Brown Howler Monkey (Alouatta guariba clamitans).

A Brown Howler Monkey presented with a femoral neck fracture was successfully treated with a cannulated compressive screw and an anti-rotational component inserted with radiographically guided technique. Complete bone consolidation and functional recovery were observed 9 weeks after the surgery, and the monkey was released to his place of origin.

Eosinophilic meningoencephalitis caused by rat lungworm (Angiostrongylus cantonensis) migration in a white-eared opossum (Didelphis albiventris) with concurrent distemper virus in southern Brazil.

Angiostrongylus cantonensis is a worldwide zoonotic parasite that causes eosinophilic meningoencephalitis in many species of animals including humans. This report describes neuro-angiostrongylosis in a white-eared opossum that showed nervous clinical signs such as circling and depression. At necropsy, no relevant macroscopic lesions were observed.

Causes of death in neotropical primates in Rio Grande do Sul State, Southern Brazil.

Background: Anthropogenic disturbances are the main threats to nonhuman primates conservation, and infectious diseases may also play a key role in primate population decline. This study aimed to determine the main causes of death in neotropical primates.

Methods: A retrospective study of post-mortem examinations was conducted on 146 neotropical primates between January 2000 and December 2018.

Wischnewski Spots and Black Oesophagus in Suspected Fatal Hypothermia in a Brown Howler Monkey (Alouatta guariba clamitans) and a Rabbit (Oryctolagus cuniculus).

Fatal hypothermia represents a diagnostic challenge in veterinary pathology. Wischnewski spots (WS) and black oesophagus (BO) have been described in human cases of fatal hypothermia but rarely in animals. We now describe WS and BO in suspected fatal hypothermia in a free-ranging brown howler monkey (Alouatta guariba clamitans) and a pet rabbit (Oryctolagus cuniculus).

Mucinous Rectal Adenocarcinoma in a Urutu Snake (Bothrops alternatus).

A 15-year-old captive female Urutu snake (Bothrops alternatus) was presented with anorexia, apathy, dehydration, pale mucous membranes and marked enlargement of the caudal third of the coelomic cavity. Radiographs and ultrasonography were suggestive of faecal impaction or neoplasia. Post-mortem findings consisted of solid faecal impaction of the intestines, secondary to obstruction caused by a rectal tumour.

Fibular and metatarsal osteosynthesis in a southern brown howler monkey (Alouatta guariba clamitans).

Here we describe a successful surgical management of a distal fibular fracture combined with a tarsocrural luxation and multiple metatarsal fractures in the left foot of a southern brown howler monkey (Alouatta guariba clamitans). We achieved satisfactory outcome by applying intramedullary pinning for each of the bone fractures and closed reduction of joint luxation-kept in place only by bone alignment, without further ligament reconstruction. Bone healing occurred uneventfully within eight weeks and the monkey's foot regained its normal function.

Pupipara (Diptera, Hippoboscidae) in wild birds attended at a rehabilitation center in southern Brazil.

The hippoboscids are cosmopolitan permanent obligate hematophagous ectoparasites of birds, domestic and wild mammals and, occasionally, humans. Some species may act as vectors or hosts of etiological pathogenic agents. The aims of this study were to report on the first cases of Hippoboscidae in Crax blumenbachii and Parabuteo unicinctus; to provide new reports from Brazil on Tyto furcata and Asio stygius parasitized by Icosta americana; to report on individuals of Bubo virginianus, Falco sparverius and Accipiter striatus parasitized by genera Ornithoctona; and to provide new reports on parasitism of O.
