A novel Sarcocystis species has recently been reported in the domestic pigeon (Columba livia f. domestica) as intermediate host, causing severe central nervous signs similar to Paramyxovirus-1 or Salmonella Typhimurium var. cop. infection. Transmissi

The paper reports the first detection of besnoitiosis of cattle in Germany. Just 2 years after the first appearance of the African Bluetongue disease (BTD) of cattle in Central Europe, another African agent of disease has arrived in Germany. While it

Faecal samples of 24,089 dogs were examined coproscopically in two veterinary laboratories in Germany between March 2001 and October 2004. In 47 dogs, oocysts of 9-14 microm size were found. Their morphology was similar to those of Hammondia heydorni

Rhesus monkey kidney cell cultures were used to propagate tachyzoites of the NC-1 strain of Neospora caninum (syn. Hammondia heydorni). The infected cell cultures were incubated for 4-12 h in media containing 0, 1, 10 or 100 microg/ml of either toltr

An evaluation of both the formal requirements of the International Rules of Zoological Nomenclature and the scientific reasons for the description of new genera and species shows that the name Neospora caninum is a nomen nudum. The only characteristi

In a previous paper we demonstrated that Hammondia heydorni-like oocysts isolated in 1996 from a naturally infected dog could not be distinguished from the isolate Neospora caninum NC-1. The isolate, designated as H. heydorni-Berlin-1996, was cyclica

In this opinion-paper reasons are given why Hammondia hammondi cannot be considered as a separate species, but should be kept as a species of the genus Toxoplasma, if not a strain of Toxoplasma gondii.

A large number of Sarcocystis spp. infect birds as intermediate hosts, but pigeons are rarely affected. We identifi ed a novel Sarcocystis sp. that causes lethal neurologic disease in domestic pigeons in Germany. Experimental infections indicated tra

The published data concerning Toxoplasma gondii, Hammondia hammondi, H. heydorni and Neospora caninum on one side and between T. gondii on the other were neglected by most authors. As conclusion we are convinced that there are only two valid species:

Mice infected with tachyzoites of Neospora caninum (syn.: Hammondia heydorni) must be pretreated with cortisone in order to show disease symptoms. This indicates the status of an opportunistic agent of disease. Toltrazuril was an effective curative a
