Abstract Trichomonas gallinae is the causative protozoan parasite of avian trichomonosis, an infectious disease wild bird species. Since outbreak in UK 2005, trichomonosis has resulted mass mortality events greenfinch ( Chloris chloris ) and chaffinch Fringillia coelebs populations. Given its proximity to UK, it important monitor emergence T. Ireland. This study proposed sample greenfinch, gold...

Metacestodes of Mesocestoides sp. were recorded from Sturnus vulgaris (Passeriformes: Stumidae) in the Czech Republic in April 2002. They were found in a cutaneous cyst and in the thoracic region of the body cavity of the bird. This is the first record of metacestodes of Mesocestoides sp. in this host species in Europe as well as the first finding of the formation of a cutaneous cyst provoked b...

Sporulated oocysts (mean dimensions = 13.0 x 10.8 microns) and sporocysts (11.3 x 5.5 microns) of a coccidian resembling Frenkelia sp. or Sarcocystis sp. were present in the lamina propria of the small intestine of a naturally-infected northern spotted owl (Strix occidentalis caurina) collected near Medford, Oregon (USA). Dimensions of these oocytes and sporocysts appear to be considerably smal...

Introduced parasites are a threat to biodiversity when naïve hosts lack effective defenses against such parasites [1]. Several parasites have recently colonized the Galápagos Islands, threatening native bird populations [2]. For example, the introduced parasitic nest fly Philornis downsi (Diptera: Muscidae) has been implicated in the decline of endangered species of Darwin's finches, such as th...

External parasites most commonly infesting poultry in California include the northern fowl mite, the common poultry mite, several kinds of lice-and the chicken tick, which is often called the blue-bug in spite of the fact that it is a true tick. In some of the warmer dry areas of the state, stick-tight fleas and western hen fleas become troublesome. Losses suffered from such parasites are often...

Anticoccidial effects of green tea (GT)-based diets were evaluated in chickens following oral infection with Eimeria maxima an ubiquitous intestinal parasite of poultry that impairs the growth and feed efficiency of infected birds. Five-week-old chickens were assigned to four groups (GT 0.5%, GT 2.0%, untreated/infected and non-infected control) and each group consisted of 15 chickens. Chickens...

A total of 969 birds representing 121 species of 21 families from the West African nations of Cameroon, Equatorial Guinea and Ivory Coast were examined for haematozoa using thin blood smears; 277 individuals (28.6%) harbored blood parasites. The parasites identified included species of Haemoproteus (7.7% prevalence), Plasmodium (10.7%), Leucocytozoon (4.6%), and Trypanosoma (7.3%). In addition,...
