There are no published reports of domestic or sylvatic trichinellosis in Te
xas. The aim of the present survey was to determine the presence of Trichin
ella species in selected representative species of potential wildlife reser
voirs in southern Texas. In 1998-99, tongues of 211 wild mammals were colle
cted in southern Texas: 154 coyotes (Canis latrans), three bobcats (lynx ru
fus), 32 racoons (Procyon lotor), 13 opossum (Didelphis marsupialis), four
ocelots (leopardus pardalis) and five wild boars (Sus scrofa). Presence of
Trichinella sp. larvae was investigated by artificial digestion and larvae
of positive samples were identified at the species level by a multiple-poly
merase chain reaction analysis. Nine (5.8%) coyotes had trichinellosis; in
the muscles of seven of these coyotes, the larvae were identified as Trichi
nella murrelli. This is the first report of sylvatic trichinellosis in Texa
s.
