Morphological and molecular identification of Sarcocystis arctica sarcocysts in three red foxes (Vulpes vulpes) from the Czech Republic.

Muscular sarcocystosis by Sarcocystis arctica was found for the first time in the Czech Republic, in different muscles of red fox (Vulpes vulpes). Cysts were slim, elongated, thread-like, whitish, 1-7mm long, and 206-270μm wide; bradyzoites were 7.9×2.

Cryptosporidium infections of ring-necked pheasants (Phasianus colchicus) from an intensive artificial breeding programme in the Czech Republic.

From July to November 2012, preliminary coprological examinations were carried out on 85 pooled faecal samples of different aged ring-necked pheasants (Phasianus colchicus) (hatches from May until July) from an intensive artificial breeding programme in the Czech Republic. Cryptosporidium oocysts were detected in 12 samples (14.1 %) of ages >12 weeks (August-September).

Stichorchis subtriquetrus (Digenea: Paramphistomatidae) from Eurasian beaver (Castor fiber) in the Czech Republic.

Between March 2012 and April 2014, we performed post-mortem parasitological examinations of 11 Eurasian beavers (Castor fiber Linnaeus, 1758) from the basins of four main rivers (Dyje, Labe, Morava, Vltava) in the Czech Republic. The cause of death of five adult animals was unknown, three adult animals died after being hit by cars, while one young and one adult as a result of serious injuries and one juvenile male drowned. The trematode Stichorchis subtriquetrus (Rudolphi, 1814) Lühe, 1909 was only found in the caecum body and caecum apex of nine beavers (82%), with no significant differences in parasite intensity among beavers.

First finding of spontaneous infections with Cryptosporidium baileyi and C. meleagridis in the red-legged partridge Alectoris rufa from an aviary in the Czech Republic.

This paper represents the first report of spontaneous infection with Cryptosporidium baileyi and Cryptosporidium meleagridis in the red-legged partridge (Alectoris rufa), as well as the percentage of positive samples and age-associated dynamics of cryptosporidial infections in an aviary in the Czech Republic. The entire infection process was monitored over two semesters (July-December 2012 and 2013) until release of birds for hunting purposes. Coprological examination of 663 pooled fecal samples and 89 post-mortem examinations of red-legged partridges were carried out.

Cryptosporidium varanii takes precedence over C. saurophilum.

We present biological as well as genetic analysis of Cryptosporidium varanii at the 18S rRNA and actin loci and show that it is genetically identical to C. saurophilum. As C.

The first finding of a natural infection of Cryptosporidium muris in a cat.

Little is known about the species of Cryptosporidium infecting cats. The limited number of genetic studies conducted to date, have all identified C. felis as the species of Cryptosporidium in cats.

Identification of novel Cryptosporidium genotypes from avian hosts.

A total of 430 avian-derived fecal specimens were randomly collected from selected Western Australian commercial aviaries, poultry farms, hatcheries, wildlife parks, and the Perth Zoo and screened for the presence of Cryptosporidium by PCR. Of these, 27 Cryptosporidium-positive isolates were detected, characterized, and compared with 11 avian-derived isolates from the Czech Republic at the 18S rRNA and actin gene loci. Sequence and phylogenetic analysis identified four genetically distinct genotypes, avian genotypes I to IV, from various avian hosts.

Detection of Anaplasma phagocytophilum in animals by real-time polymerase chain reaction.

The aim of this study was to detect Anaplasma phagocytophilum in wild and domesticated animals and to identify the phylogenetic relationships of different strains of this bacterium. We adapted six published conventional methods targeting 16S fragments for real-time polymerase chain reaction. Initial screening of samples from 419 animals found 37 Anaplasma positives, later confirmed with several different primers and a TaqMan probe.

Identification of novel Cryptosporidium genotypes from the Czech Republic.

Isolates of Cryptosporidium from the Czech Republic were characterized from a variety of different hosts using sequence and phylogenetic analysis of the 18S ribosomal DNA and the heat-shock (HSP-70) gene. Analysis expanded the host range of accepted species and identified several novel genotypes, including horse, Eurasian woodcock, rabbit, and cervid genotypes.
