Detection of feline coronavirus in captive Felidae in the USA.
J. Vet. Diagn. Invest 14: 520-522.

Feline coronavirus (FCoV) is an important pathogen of domestic and nondomestic Felidae. Investigation into the prevalence of FCoV in exotic Felidae has relied primarily on serology. The usefulness of genetic detection of FCoV using reverse transcription and nested polymerase chain reaction (RT/nPCR) for viral screening was investigated. Seventy-five biologic samples, primarily feces, from captive felids from 11 institutions were tested using PCR. Serum samples collected from all but 12 of these animals were tested for antibodies to type I and type II FCoV by indirect immunofluorescence. Twenty-four animals were positive using RT/nPCR for virus. Twenty-nine animals were seropositive to type I and/or type II FCoV. From serologic data, infection with a virus antigenically related to FCoV type I occurred most commonly. Serology did not correlate with virus shedding because 13 animals were seronegative to FCoV type I and II but positive using RT/nPCR for virus. Conversely, 20 animals were seropositive but negative using RT/nPCR for FCoV. Some of the populations in which virus was detected had experienced health problems, including feline infectious peritonitis (FIP), necrotizing colitis, and mild enteritis. In addition to its role in FTP, this virus may play a role in gastrointestinal diseases of infected animals. This study demonstrates that FCoV is a significant infectious agent of captive felids because over half o the animals tested were positive by viral genetic detection, serology, or both. Dependence upon one method for detection of infection is unreliable.

Kratochvil, J. et al. 1968.
History of the distribution of the lynx in Europe.
Acta sc. nat. Brno, 2(4): 1-50.

The process of disappearance of the lynx is drawn in general; the latest occurrence of this carnivore is evidenced in those countries in which it had been extinct (J. Kratochvil); changes in the area of its distribution in Europe are described (N.K. Verescagin, S.V. Kirikov). We are relatively well informed on the process of disappearance of the lynx from W. Europe, especially in France, as summarized in a paper (by M-Ch. Saint Girons) in this report. In this volume, the process of disappearance of the lynx in S. Europe is illustrated in the papers by A. Toschi and N. Atanasov, and in C. Europe in those by J. Kratochvil and F. Vala. The reasons are discussed of the extermination of the lynx in the cultivated areas of many European countries, as well as the possibility for its conservation in countries of its present occurrence.

Kurtén, B. and Granqvist, E. 1987.
Fossil pardel lynx (Lynx pardina spelaea Boule) from a cave in southern France.
Annales Zoologici Fennici 24: 39-43.

A felid skull form the Aven du Puech Margal, St. Jean de Maruejois (Gard) is referred to the large Pleistocene subspecies of pardel lynx, L. pardina spelaea Boule. It confirms the presence of pardel lynx in southern France inthe late Pleistocene. Some diagnostic characters differentiating the fossil pardel lynx from the equally large L. lynx are discussed.

Kurtén, B. and Werdelin, L. 1984.
The relationships of Lynx shansius Teilhard.
Annales Zoologici Fennici 21: 129-133.

A sample of specimens of Lynx shanius Teilhard has been compared to similar samples of L. lynx from Sweden and Finland, L. pardina from Spain, and L. issiodorensis from Etouaires. Results show that L. shanius is only subspecifically distinct from L. issiodorensis. No conclusions can be drawn concerning the evolution of L. lynx on the basis of L. shanius.
