Parasites, which are considered a subclass of predators, are important controllers of host species density (Primack & Rodrigues, 2001). In Brazil, although data on parasites of domestic mammals are quite common (Nichol et al., 1981; Farias et al., 1995; Pimentel Neto & Fonseca, 2002; Serra et al., 2003), studies about helminth parasites preying on arboreal rodents are rare due to the general la...

Helminthic parasites cause widespread, persistent infections in humans. The immigration of Ethiopians to Israel (a group denoted here by "Eth."), many of them infested with helminths and in a chronic immune-activation state, enabled us to investigate the effects of such immune activation on immune responses. We studied the immune profile and immune functions of 190 Eth. and Israeli non-Eth. (Is...

Introduction: Intestinal Schistosomiasis and Soil transmitted helminthic infections (STIs) are among the major public health problems in the world, especially in Subsaharan Africa. Objective: To determine the prevalence of intestinal schistosomiais and soil transmitted helminthic infections and associated factors among Umolante primary school children, South Ethiopia. Methods: A cross sectional...

Eosinophilic meningitis is defined by the presence of 10 or more eosinophils per microliter in the cerebrospinal fluid (CSF) or eosinophilia of at least 10% of the total CSF leucocyte count.1 It is rare in Western countries, where it is sometimes seen in association with tuberculosis, syphilis, and coccidioidomycosis.2 Worldwide, the most common cause of eosinophilic meningitis is invasion of t...

To determine the status of infection caused by intestinal parasites among children and adolescents living in Legaspi city, the Philippines, we performed a small survey by fecal examination for helminth ova and protozoan cysts with formalin-ether concentration method. Of the 64 examinees, the infection rate was 78.1%. The infection rates of primary school children, preschool children and adolesc...

As the scope of international travel expands, an increasing number of travelers are coming into contact with helminthic parasites rarely seen outside the tropics. As a result, the occurrence of Gnathostoma spinigerum infection leading to the clinical syndrome gnathostomiasis is increasing. In areas where Gnathostoma is not endemic, few clinicians are familiar with this disease. To highlight thi...

BACKGROUND Dynamic interactions between the host and gastrointestinal microbiota play an important role for local and systemic immune homeostasis. Helminthic parasites modulate the host immune response, resulting in protection against autoimmune disease but also increased susceptibility to pathogen infection. The underlying mechanisms remain largely unknown. RESULTS We showed that the type 2 ...
