SURVEY OF Salmonella spp., Escherichia coli and Staphylococcus aureus IN ARDEIDS: INVESTIGATION OF POTENTIAL RESERVOIRS.

Ardeids are wild birds well adapted to urban and periurban environments. However, the association of wildlife with humans and livestock increases the chances of transmission of microorganisms between wild animals, domestic animals and humans. The present study aimed to investigate the occurrence of Salmonella spp.

Parasitological surveillance in a rat (Rattus norvegicus) colony in São Paulo Zoo animal house.

Rattus norvegicus (Mammalia: Rodentia) is a widespread and synanthropic rodent, broadly used in medical experiments. It can also be used for feeding captive animals in zoos. Parasitological surveys are important to guarantee the health of both the animals and the staff responsible for their management.

Antitoxin therapy of natural avian botulism outbreaks occurred in Brazil.

Botulism commonly affects water birds and it has recently been observed to be emerging in poultry production. In the present work, outbreaks of botulism in wild native species, such as the black-fronted Piping-guan (Aburria jacutinga), wild duck (Cairina moschata) and its crosses with mallard (Anas platyrhynchos), and domestic chickens (Gallus gallus domesticus) are described. Following treatments with a commercial botulism antitoxin CD, 28 (96.

Cryopreservation of red brocket deer semen (Mazama americana): comparison between three extenders.

In recent years, genome banks have grown as a way of maintaining the genetic variability of populations. However, the quality of gamete cryopreservation will determine their efficiency. This study aimed to evaluate prefreeze and postthaw sperm motility, vigor, membrane integrity, and morphology of semen of red brocket deer (Mazama americana) using three extenders: E1, Tris-Yolk; E2, Tes-Tris-Yolk; and E3, Tes-Tris-Yolk-Equex.
