alpha toxin enteritis associated with pulmonary disease in a neotropical otter (, Olfers, 1818) under human care.

alpha toxin (CPA) is an important enterotoxemic pathogen linked to gastrointestinal disorders and previously associated with pulmonary disease in other mammals. A young female neotropical otter presented with lethargy, anorexia and steatorrhea, which developed within 24 hours. Veterinary care was provided under anesthesia, during which dehydration, intestinal hypermotility and pulmonary crackling sounds were identified.

Anesthetic effects of the ketamine and midazolam association by intranasal or intramuscular route in domestic chickens: prospective, blinded, randomized and crossover study.

This prospective, blinded, randomized crossover study aimed to assess the anesthetic effects of the combination of 30 mg/kg ketamine and 2 mg/kg midazolam via intranasal (IN) or intramuscular (IM) routes in twelve domestic chickens. Physiological parameters (respiratory rate - RR, heart rate - HR, and cloacal temperature -Tºcloacal) were monitored throughout the experiment, along with recovery time and sedation level (S0: awake, no recumbency, responsive to stimuli; S1: blinking eyes, recumbency, relaxed, response to stimulus, mild movement; S2: open eyes, recumbency, relaxed, mild response to stimuli; S3: closed eyes, recumbency, relaxed, no movement). In the IM group, all birds reached S3, while in IN 5/12 reached S3, 4/12 reached at most S1, and 1/12 at most S2.

Endoparasites of (Carnivora, Felidae) rescued in the State of Rio de Janeiro.

Wild cats play an important role as top predators in the food chain and act as ecosystem regulators. However, in recent decades, many studies have demonstrated the potential effects of parasitic diseases on wild carnivore populations, including cats. This study reports on the endoparasites found in an injured and rescued specimen of in the state of Rio de Janeiro.

Parasitism by Koch, 1844 (Acari: Ixodidae) associated with blefaritis on a red-footed tortoise () in Rio de Janeiro state - case report.

is a tick species commonly found on reptiles and amphibians. In Brazil, investigations of this ectoparasite have indicated its distribution across all Brazilian biomes, although it is concentrated in certain locations. In this context, the objective of the present study was to describe a case of parasitism by in a red-footed tortoise () in the state of Rio de Janeiro.

Molecular detection of hemoplasmas in rescued black-eared opossums (Didelphis aurita Wied-Neuwied, 1826) from southeastern Brazil, with evidence of a novel genotype infecting marsupials.

There is a growing concern about the participation of wild hosts and reservoirs in the epidemiology of several pathogens, particularly within the context of environmental changes and the expansion of the One Health concept. The aim of this study was to investigate the presence of hemoplasmas in opossums rescued from the metropolitan region of Rio de Janeiro state, Brazil. Blood samples were collected from 15 Didelphis aurita and subjected to DNA extraction and PCR using primers for the 16S rRNA and 23S rRNA genes.

Anesthetic effects of isoflurane and fentanyl infusion in capuchin monkeys (Sapajus sp) undergoing salpingectomy or deferentectomy, previously chemically restrained with ketamine-midazolam or ketamine-dexmedetomidine.

Background: This study evaluated the anesthetic and cardiorespiratory effects of two anesthetic protocols for salpingectomy or deferentectomy in capuchin monkeys (Sapajus sp).

Materials And Methods: Five capuchin monkeys (5 per group) received ketamine (20 mg/kg) combined with midazolam (0.5 mg/kg; group KM) or dexmedetomidine (5 μg/kg; group KD) intramuscularly.

Molecular epidemiology of Blastocystis isolated from animals in the state of Rio de Janeiro, Brazil.

The enteric protist Blastocystis is one of the most frequently reported parasites infecting both humans and many other animal hosts worldwide. A remarkable genetic diversity has been observed in the species, with 17 different subtypes (STs) on a molecular phylogeny based on small subunit RNA genes (SSU rDNA). Nonetheless, information regarding its distribution, diversity and zoonotic potential remains still scarce, especially in groups other than primates.

Molecular and morphological characterization of Contracaecum pelagicum (Nematoda) parasitizing Spheniscus magellanicus (Chordata) from Brazilian waters.

Three new sequences of Mitochondrial cytochrome c-oxidase subunit 2 (mtDNA cox-2) from C. pelagicum parasite of Spheniscus magellanicus, the Magelanicus penguin, were determined from Brazilian waters. The sequences presented 99 and 98% of similarity with C.
