background: the aim was to study the gastro-intestinal helminths of stray dogs of garmsar, sem­nan province, central iran, and its impacts on human health and animal production. methods : during 2006, the alimentary tracts of 50 stray dogs at necropsy, selected from villages around garmsar, were removed, and examined for helminth infections. subsequently helminths were collected from the conten...

BACKGROUND The effect of helminth infections on allergic diseases is still inconclusive. Furthermore, the effect of helminth infections on childhood allergic diseases in a tropical area where prevalence of helminth infections has undergone dramatic changes is not well documented. OBJECTIVE To investigate the relationship between allergic diseases and helminth infection in a cohort of schoolch...

Current iterations of the hygiene hypothesis suggest an adaptive role for helminth parasites in shaping the proper maturation of the immune system. However, aspects of this hypothesis are based on assumptions that may not fully account for realities about human helminth infections. Such realities include evidence of causal associations between helminth infections and asthma or inflammatory bowe...

Helminth infections affect more than a third of the world's population. Despite very broad phylogenetic differences among helminth parasite species, a systemic Th2 host immune response is typically associated with long-term helminth infections, also known as the "helminth effect". Many investigations have been carried out to study host gene expression profiles during helminth infections. The ob...

BACKGROUND Within sub-Saharan Africa, helminth and malaria infections cause considerable morbidity in HIV-positive pregnant women and their offspring. Helminth infections are also associated with a higher risk of mother-to-child HIV transmission. The aim of this study was to determine the prevalence of, and the protective and risk factors for helminth and malaria infections in pregnant HIV-posi...

Zoonotic infections are among the most common on earth and are responsible for >60 per cent of all human infectious diseases. Some of the most important and well-known human zoonoses are caused by worm or helminth parasites, including species of nematodes (trichinellosis), cestodes (cysticercosis, echinococcosis) and trematodes (schistosomiasis). However, along with social, epidemiological and ...

BACKGROUND Bidirectional signalling between the brain and the gastrointestinal tract is regulated at neural, hormonal, and immunological levels. Recent studies have shown that helminth infections can alter the normal gut microbiota. Studies have also shown that the gut microbiota is instrumental in the normal development, maturation and function of the brain. The pathophysiological pathways by ...

BACKGROUND Despite the high prevalence of helminth infections among preschool-aged children, control programs in sub-Saharan countries primarily focus on school-aged populations. We assessed the prevalence of helminth infections and determined risk factors for infection among preschool-aged children in the urban setting of Dar es Salaam, Tanzania. METHODOLOGY Starting in October 2015, we cond...

BACKGROUND It has been hypothesized that helminth infections increase HIV susceptibility by enhancing systemic immune activation and hence contribute to elevated HIV-1 transmission in sub-Saharan Africa. OBJECTIVE To study systemic immune activation and HIV-1 co-receptor expression in relation to different helminth infections and in response to helminth treatment. METHODS HIV-negative adult...

Helminth parasite infection of the canine and feline respiratory tract is uncommon in North America. This article reviews the prevalence, etiology, diagnosis, and treatment of helminth parasite infections in dogs and cats. The diagnosis of parasitic infections caused by helminth parasites of the respiratory tract of cats and dogs is infrequent in most parts of North America. Several fecal exami...
