Dear Colleagues,

On behalf of all co-authors, I am pleased to announce the publication of
our article about *Toxoplasma gondii* in cetaceans of Brazil.

Costa-Silva S, Sacristan C, Gonzales-Viera O, Diaz-Delgado J,
Sanchez-Sarmiento AM, Marigo J, Groch KR, Carvalho VL, Ewbank AC, Colosio
AC, Marcondes MCC, de Meirelles ACO, Bertozzi CP, Lailson-Brito JJr,
Azevedo AF, Ruoppolo V, Oliveira L, Ott PH, Catao-Dias JL. (2019). *Toxoplasma
gondii *in cetaceans of Brazil: a histopathological and immunohistochemical
survey. Brazilian Journal of Veterinary Parasitology. Brazilian Journal of
Veterinary Parasitology.

In this manuscript we investigated the occurrence of *T. gondii *by
histopathology and immunohistochemistry in tissue samples of 185 animals
comprising 20 different cetacean species from Brazil. Three out of 185
(1.6%) animals presented *T. gondii*-associated lesions: a captive killer
whale *Orcinus orca*, a free-ranging common bottlenose dolphin *Tursiops
truncatus* and a free-ranging Guiana dolphin *Sotalia guianensis*. The main
lesions observed in these animals were necrotizing hepatitis, adrenalitis
and lymphadenitis associated with protozoal cysts or extracellular
tachyzoites presenting immunolabeling with anti-*T. gondii* antibodies.
This study widens the spectrum of species and the geographic range of this
agent in Brazil, and provides the first reports of* T. gondii *infection in
a captive killer whale and in a free-ranging common bottlenose dolphin in
South America.
