| occurrence of puma lentivirus infection in cougars from washington. | puma lentivirus (plv) antibodies were detected in 13 (25%) of 52 serum samples obtained from cougars (felis concolor) collected by hunters. the serum samples were collected from november 1993 through january 1994 from four specific regions throughout the state of washington (usa), and included the olympic mountains, the cascade mountains, the blue mountains, and the selkirk mountains. more (38%) seropositive cougar samples originated from the cascade mountains than from any other site. the overa ... | 1997 | 9131566 |
| cylicospirura species (nematoda: spirocercidae) and stomach nodules in cougars (puma concolor) and bobcats (lynx rufus) in oregon. | the stomachs and proximal duodena of 160 cougars (puma concolor) and 17 bobcats (lynx rufus), obtained throughout oregon during 7 yr, were examined for cylicospirura spp. and associated lesions. prevalence in cougars was 73%, with a range in intensity of 1-562 worms. the mean diameter of nodules was 1.2 cm (sd=0.5), and many extended through the submucosa to the muscularis. about 83% of cougars had nodules; most nodules contained worms, but 14% of the smaller nodules (<0.2 cm) contained porcupin ... | 2011 | 21270003 |
| acute lead toxicosis via ingestion of spent ammunition in a free-ranging cougar (puma concolor). | lead toxicity has long been documented and acknowledged as a significant health issue of water birds and avian scavengers. however, few instances of toxic effects to higher mammalian carnivores have been documented. here we present an acute case of lead toxicity in a free-ranging cougar (puma concolor) in oregon. | 2012 | 22247395 |

| seroprevalence of toxoplasma gondii in american free-ranging or captive pumas (felis concolor) and bobcats (lynx rufus). | toxoplasma gondii is a major zoonotic agent infecting a wide range of mammals, including wild felids. like domestic cats, wild felids are involved in the complete infective cycle of t. gondii, as they can host in their gastrointestinal tract sexually mature parasites and shed infective oocysts in their feces. in order to evaluate the importance of this wildlife reservoir, 438 serum samples collected between 1984 and 1999 from 438 pumas (felis concolor) and from 58 bobcats (lynx rufus) from north ... | 2004 | 15019138 |
