Consequences of concurrent Ascaridia galli and Escherichia coli infections in chickens

Three experiments were carried out to examine the consequences of concurrent infections with Ascaridia galli and Escherichia coli in chickens raised for table egg production. Characteristic pathological lesions including airsacculitis, peritonitis and/or polyserositis were seen in all groups infected with E. coli. Furthermore, a trend for increased mortality rates was observed in groups infected with both organisms which, however, could not be confirmed statistically. The mean worm burden was significantly lower in combined infection groups compared to groups infected only with A. galli. It was also shown that combined infections of E. coli and A. galli had an added significant negative impact on weight gain

New hosts of some nematodes - parasites of Passeriformes

Parasitic nematodes very rarely exist in birds that are completely or predominantly herbivorous. The investigation of the helminth fauna of Passeriformes in the region of Lower Silesia revealed new hosts for some nematode species. We found in Acrocephalus scirpaceus – Acuaria subula and Microtetrameres inermis; in Fringilla coelebs and in Luscinia megarhynchos – Dispharynx nasuta; in Passer montanus – Capillaria angusta; in Phylloscopus trochiloides – Acuaria subula as well in Phylloscopus collybita – Microtetrameres sp. These nematodes have not been so far reported from these bird species

Red fox (Vulpes vulpes) as reservoir of parasites and source of zoonosis. This review presents data from Europe and Poland on the prevalence of helminth and protozoan parasites in red foxes (Vulpes vulpes). The most common nematodes were geohelminths: Uncinaria stenocephala, Toxocara canis and Toxocara leonina. As concerning Trichinella genus T. britovi was found more often than T. spiralis. Among tapeworms the following species were recorded: Mesocestoides lineatus, Taenia sp., and Echinococcus multilocularis. Detected cases of E. Multilocularis together with an increase of fox population during last few years create a potential human risk of infection. The results of many studies indicate rare presence of trematodes (Alaria alata) and protozoan parasites (Toxoplasma gondii, Neospora caninum, Leishmania spp., Eimeria spp.) in red foxes
