|
In the first part of this study the literature concerning herpes virus infections in reptiles is reviewed. Since the emphasis is on herpesvirus infections in tortoises, which are often characterized by respiratory distress, other respiratory disorders of tortoises are also described.The regimen of the serum neutralization test is adapted to the requirements of tortoise herpes virus and tortoise serum. The test is used to discriminate between infected and uninfected animals. A total of 784 serum samples from 24 tortoise species was assayed. Neutralizing antibodies were demonstrated in 12 species. A larger number (n>20) of sera was collected from the following species: Testudo hermanni, Testudo graeca, Testudo horsfieldii, Testudo kleinmanni, Testudo marginata and Testudo carbonaria.Tortoise herpes virus was isolated from Testudo hermanni, Testudo graeca and Testudo horsfieldii, which were in the initial phase of clinical disease, by inoculating TE-cells with swab samples from the oral cavities. Furthermore isolation attempts from post mortem materials from Testudo graeca, Testudo hermanni, Testudo marginata and Testudo horsfieldii were successful. In the diseased tortoises no sex disposition was seen. Cross neutralization of five herpes virus isolates from different collections showed a close relationship between the viruses tested.Contrary to the high morbidity and mortality in Testudo hermanni, Testudo kleinmanni and Testudo horsfieldii, the prevalence of antibodies against herpes virus is comparatively low. However in Testudo graeca, Testudo marginata and Testudo carbonaria a high number of serological reactors was detected.Since infections with herpesviruses always lead to the development of latent infections, surviving animals must always be regarded as possible vectors. Accordingly contact with uninfected tortoise collections must be avoided. Testudinidae
