Zoonoses are infectious diseases of animals that can be transmitted to humans. Human dirofilariosis (caused by Dirofilaria repens and Dirofilaria immitis) are among the helminthic zoonoses most frequently diagnosed in Europe. Indeed, human infections with Dirofilaria parasites are diagnosed with increasing frequency in many European countries and are currently included in the socalled emerging ...

After a useful account of sigmoidoscopy, a short historical survey and a discussion of their geographical distribution, the bacillary, protozoal, and helminthic dysenteries are described in considerable detail. Following this well documented and balanced survey, it is disappointing to have paratyphoid infections and food poisoning dismissed in four pages, especially as it is admitted that parat...

Recent studies in Africa and Asia indicate that different helminthic infections adversely affect the clinical outcome of malaria infections. This suggests that helminths can influence the acquisition of immunity against Plasmodium. Worms could constitute a confounding factor in the assessment of efficacy of malaria-control intervention, including vaccine prototypes in clinical trials. These obs...

S. Romagnanl (Italy) stressed that in the past few years great progress has been made in the knowledge of the cellular and molecular signals responsible for the regulation of human immunoglobulin E (IgE) synthesis. Interleukin-4 (IL-4) and interferon-gamma (IFN-y) are the main regulatory cytokines of lgE production, with opposite effects. T helper (Tii) cells producing IL-4 and IL-5, but no, or...

Soil-transmitted helminths (STH) infect 2 billion people worldwide including significant numbers in South-East Asia (SEA). In Australia, STH are of less concern; however, indigenous communities are endemic for STH, including Strongyloides stercoralis, as well as for serious clinical infections due to other helminths such as Toxocara spp. The zoonotic hookworm Ancylostoma ceylanicum is also pres...

A study to establish the prevalence of intestinal helminthiases among schoolchildren of riverine communities in the Ilaje-Ese Odo Local Government Area of Ondo State, Nigeria was conducted. Ninety-four percent of the children studied were infected with intestinal helminths. Trichuris trichiura infection was the commonest (84%), followed by Ascaris lumbricoides (75.3 %) and hookworm (7.6 %). Dua...

Unlike acute diarrhea, the role of pathogens in persistent diarrhea in children in Nepal is unclear. Protozoal parasites are suspected to be a major cause. The study was carried out to find the association between protozoal agents and persistent diarrhea in children below age 5 years from western Nepal. Stool samples were collected from 253 children with persistent diarrhea, from 155 children w...
