[The biology of Dipylidium caninum. Part 2]. / Beitrag zur Biologie des Dipylidium caninum. 2. Mitteilung.

From 198 cats and 182 dogs in Austria 9,134 fleas were collected. Ctenocephalides felis is the main flea of our cats (98.5%) and dogs (77.5%). Demonstration of cysticercoids of Dipylidium caninum through bleaching of fleas failed. Dissection of fleas gave, however, positive results. Each 44th flea from cats and 61st flea from dogs harbours cysticercoids. Infection intensity rates were 2.3% for C. felis (cats), 1.2% for C. felis (dogs), and 3.1% for C. canis (dogs). Male fleas are more extensively, but less intensively infected than female fleas. Cysticercoids form fleas of feline origin are more infective to cats than those from fleas found on dogs. The longest patency in cats lasted 3 years.

Borrelia infections of ruminants in Europe.

The occurrence of Borrelia spirochaetes in cattle in the Netherlands is reported for the second time, and in red deer and roe-deer in Austria for the first time. It is postulated that these spirochaetes are Borrelia burgdorferi rather than B. theileri. The reservoir role of ruminants in the epidemiology of human disease caused by B. burgdorferi in Europe should be investigated.
