Molecular genetic investigations on Balantidium ctenopharyngodoni Chen, 1955, a parasite of the grass carp (Ctenopharyngodon idella).

Acta Vet Hung 2016 Jun;64(2):213-21

Institute for Veterinary Medical Research, Centre for Agricultural Research, Hungarian Academy of Sciences , P.O. Box 18, H-1581 Budapest , Hungary.

Balantidium ctenopharyngodoni is a common ciliate in Hungary, infecting the hindgut of grass carp (Ctenopharyngodon idella), a cyprinid fish of Chinese origin. Although data have already been presented on its occasional pathogenic effect on the endothelium of the host, generally it is a harmless inhabitant of the gut. Phylogenetic analysis of the 18S rDNA and ITS fragments of this protozoan proved that it is in the closest phylogenetic relationship with endocommensalist and symbiont ciliates of mammals feeding on large volumes of green forage, in a similar way as Balantidium spp. Read More

Department of Colorectal Surgery, Virginia Hospital Center, Arlington, Virginia.

Over one billion people worldwide harbor intestinal parasites. Parasitic intestinal infections have a predilection for developing countries due to overcrowding and poor sanitation but are also found in developed nations, such as the United States, particularly in immigrants or in the setting of sporadic outbreaks. Although the majority of people are asymptomatically colonized with parasites, the clinical presentation can range from mild abdominal discomfort or diarrhea to serious complications, such as perforation or bleeding.

New insights into the molecular phylogeny of Balantidium (Ciliophora, Vetibuliferida) based on the analysis of new sequences of species from fish hosts.

Hubei Key Laboratory of Animal Nutrition and Feed Science, Wuhan Polytechnic University, Wuhan, 430023, China.

We obtained sequences of the small subunit ribosomal RNA (rRNA) for two new isolates of Balantidium from fishes, Balantidium polyvacuolum and Balantidium ctenopharingodoni. This is the first introduction of molecular data of Balantidium species from fish hosts in the phylogenetic analyses of the ciliate subclass Trichostomatia. Despite the fact that these species share morphological characteristics common to other species of Balantidium, the phylogenetic analysis of their sequences has shown that they are to be placed in a different branch closely related to the so-called Australian clade.

Wildlife population management is thought to destabilize existing host-parasite equilibriums in opposing directions, that is, it may increase parasite success or host resilience once infection takes place. This process is of special importance for species such as the wild boar (Sus scrofa) that are managed for game purposes throughout much of Europe. However, little is known about how this practices influcences either gastrointestinal or pulmonary parasitism in the wild boar. Read More

Balantidium coli is a cosmopolitan parasitic-opportunistic pathogen that can be found throughout the world. Pigs are its reservoir hosts, and humans become infected through direct or indirect contact with pigs. In rural areas and in some developing countries where pig and human fecal matter contaminates the water supply, there is a greater likelihood that balantidiosis may develop in humans. Read More

Tentative identification of the species of Balantidium from ostriches (Struthio camelus) as Balantidium coli-like by analysis of polymorphic DNA.

Vet Parasitol 2008 Oct 2;157(1-2):41-9. Epub 2008 Jul 2.

The characteristics of Balantidium from ostriches (Struthio camelus) are similar to those of Balantidium coli; however, the species Balantidium struthionis was proposed on the basis of the host species (ostriches) and the shape of the macronucleus (with a deep depression in one side). In the present work, we have performed morphological and genetic comparisons between isolates of Balantidium from ostriches and B. coli from pigs to determine the specific status of B. Read More
