The red brocket deer (Mazama americana) as a new intermediate host of Taenia omissa (Taeniidae).

A total of 13 metacestodes were collected from the lung and parietal pleura from a red brocket deer (Mazama americana) from the Peruvian Amazon. All metacestodes were identified as cysticerci of Taenia omissa by morphological and molecular analyzes. Cytochrome c oxidase subunit 1 sequences from the new isolate T. omissa had more than 96.8% identity with other Peruvian isolates of the species previously sequenced. Lower similarities (93.8-95.8%) were verified between Peruvian and Canadian isolates. This finding adds a new intermediate host for T. omissa and also expands its geographical distribution.

Nutrition of Six Selected Neo-Tropical Mammals in Trinidad and Tobago with the Potential for Domestication.

This review highlights the available literature on the nutrition of six neo-tropical animals with the potential for domestication-the agouti (Dasyprocta leporina/D. aguti), lappe (Agouti paca), capybara (Hydrochoerus hydrochaeris), manicou/opossum (Didelphis marsupialis insularis), collared peccary (Peccary tajucu) and the red brokcet deer (Mazama americana). Over 100 references were used, spanning over 100 years. The earliest being 1915 and the most recent being 2018. The references used in this review were synthesized to give a detailed look of the dentition, anatomy of the gastrointestinal tract and type of feed these animals consume. Nutritional requirements of the animals are required to understand what is needed for growth, maintenance and reproduction of each physiological stage. The agouti (D. leporina/D. aguti) was observed to be a monogastric mammal that fed primarily on fruits, seeds, animal matter and practiced caecotrophy. The lappe/paca (C. paca/A. paca) was described as a strict herbivore and a frugivore which practiced caecotrophy, with a diet that varied throughout the year, according to food availability. The capybara (H. hydrochaeris) was found to be the largest known rodent and was described as a semiaquatic hindgut fermenter that practiced caecotrophy. The manicou/opossum (D. marsupialis insularis) was found to be an omnivore with a simple stomach. The collared peccary (T. tajacu) was found to be frugivorous. Their unique stomach enabled them to consume a wide variety of feedstuff, allowing them to be found in a wide range of habitats. The red brocket deer (M. americana), a ruminant, was described as a browser that consumed mainly fruits and seeds and they frequented mineral lick. Knowledge of what they consume in the wild is important, so that we know what to feed in captivity. There is also the need to evaluate captive diets while trying to domesticate these mammals and develop nutrient requirement tables for these neo-tropical animals. Finally, an understanding of the dentition and gastrointestinal tract is important to increase efficiency (nutritional and cost). These six neo-tropical mammals were chosen due to their prevalence as game species in Trinidad and Tobago.

Helmintos de veados- mateiros (Mazama americana) e suas implicações a criação de ruminantes domésticos – revisão de literatura / Red brocket deer helminthes (Mazama americana) and its implications the ruminants domestics creation- literature review

Mazama americana é conhecido popularmente como veado-mateiro, sendo distinguido por meio da coloração do pelo, marrom avermelhada, região posterior arqueada, corpo robusto, cauda curta, orelhas médias, rosto alongado e membros delgados. Diversas espécies de helmintos, principalmente nematódeos podem ser encontrados parasitando ruminantes domésticos e silvestres. O conhecimento da fauna helmintológica de cervos é de suma importância para determinar a possibilidade de transmissão desses agentes pra animais domésticos e ao homem, bem como na necessidade de realização de monitoramentos periódicos por meio de testes de diagnósticos, visando o conhecimento da magnitude das infecções causadas por esses agentes.

Mazama Americana is better known as Red Brocket. The species is distinguished by its reddish brown color, posterior arcuate region and robust body, short tail, middle ear, face and elongated slender members. Several species of helminths, especially nematodes can be found parasitizing domestic and wild ruminants. Knowledge of helminth fauna of deer is very important to determine the possibility of transmitting these agents to domestic animals and humans as well as is the need to conduct periodic monitoring through diagnostic tests to aknowledge the magnitude of the infections caused by these agents.
