A cross-sectional survey was carried out on 2004-2005 in the Campania region, southern Italy, to study the multivariate geographical distribution of four different sheep helminths, i.e. Fasciola hepatica (liver fluke), Calicophoron (Paramphistomum) daubneyi (rumen fluke), Dicrocoelium dendriticum (lancet fluke), and the gastrointestinal strongyle Haemonchus contortus. A series of multivariate B...

Intestinal helminths are known to subvert the host's immune response towards a Th2 response, which in turn may lead to both eosinophilia and high immunoglobulin E titers often associated with these parasites. Mycobacterium leprae infection may lead to different clinical and pathological forms. Multibacillary forms are associated with Th2 cytokines, whereas paucibacillary forms are associated wi...

Over 1,000,000,000 people and innumerable other animals are currently infected with one or more helminths [1]. These highly prevalent infections contribute to significant illness and economic losses due to impaired worker productivity and livestock health. As such, it is tremendously important to vaccine and anthelminthic drug development efforts to understand the complex interactions between h...

Information on species of parasitic helminths native to Poland is provided by the Pasozytnicze helminty Polski. Gatunki. Zywiciele. Białe Plamy. Until the middle of 2007, there were 1205 species of recorded helminths including 126 species of Monogenea, 338 of Trematoda (Digenea), 279 of Cestoda, 427 of Nematoda and 35 of Acanthocephala. They represented 32.9% of the species recorded in Europe (...

Nitric oxide (NO) is a very simple molecule that displays very important functions both in helminths (mainly those involved in respiratory pathology) and in mammalian hosts. In this paper we review four issues related to interaction of NO and lung helminthic diseases. Firstly, we evaluated data available on the NO synthesis and release by helminths and their biological role. Next, we summarized...

This investigation was undertaken to verify the prevalence of helminths parasites in the gastrointestinal tract of catfish. A total number of 116 catfish (Silurus glanis) were collected from Zarrine-roud river and examined for helminths. Fish were examined after washing contents of gastrointestinal tract and observed for the presence of helminths using a stereo microscope and a light microscope...

Mechanisms and outcomes of host-parasite interactions during malaria co-infections with gastrointestinal helminths are reasonably understood. In contrast, very little is known about such mechanisms in cases of malaria co-infections with tissue-dwelling parasites. This is lack of knowledge is exacerbated by misdiagnosis, lack of pathognomonic clinical signs and the chronic nature of tissue-dwell...

In this study, two mountain frogs (Rana camerani and Rana macrocnemis) were collected in the Antalya Province in south-western Turkey during 2001 and 2002 and were examined for helminths. Out of 15 Rana camerani, 10 (66.7%) were infected with 1 or more helminths and out of 20 Rana macrocnemis, 17 (85%) were infected with 1 or more helminths. The helminth fauna of Rana camerani included 4 specie...

Helminth is a nonphylogenetic term that refers to multicellular animals (or metazoans) that have adopted a parasitic lifestyle in mammalian hosts. They are more commonly referred to as parasitic worms. These worms generally (with the exception of Strongyloides stercoralis) cannot replicate within the host, and they have evolved distinct methods to co-exist with their host through the activation...

Gastrointestinal parasites are responsible for heavy economic and production lossesin bovines. The present study was conducted to determine the prevalence of gastrointestinal (GI)helminths bovine in different zones Rawalpindi district. Study area divided into fourdifferent zones. Feacal samples (n=670) were collected examined through coprologicalexamination techniques. Out samples, 158 found be...
