A preliminary report on the awareness and knowledge of seafood-borne parasitic diseases among medical doctors in Australia

Publication date: Available online 12 September 2019Source: Parasitology InternationalAuthor(s): Alexa Seal, Catherine Harding, Shokoofeh ShamsiAbstractDespite the increasing popularity of seafood in Australia and various reports of infection with transmissible parasites in Australian edible aquatic animals such as fish, the number of reported cases of human infections in the country is low. This raised the question that Australian medical doctors may not be fully aware of the presence of these parasites in Australia, which in turn can lead to misdiagnosis of infections. This also may lead to an underestimation of the risk seafood-borne parasites may pose to public health. This preliminary study was conducted to determine the awareness and level of knowledge among Australian medical practitioners in New South Wales, the most populated and multicultural state in Australia, about seafood-borne parasitic diseases. Medical doctors, both general practitioners and gastroenterologists, were surveyed through an anonymous questionnaire (n = 376). Although the response rate was low at 11%, participants represented a diverse group in terms of gender, age, nationality and expertise. Despite several publications on occurrence of zoonotic parasites in Australian fish and other edible aquatic animals, and also in humans in the country, all respondents said no seafood-borne parasite had been reported as being seen within Australian or overseas practice. Although, due to low response rate...

ConclusionOur findings indicate that cryptic myiasis cases due to the obligate parasite,C.bezziana, are under-recognized. Through this study onC.bezziana etiology, clinical features, diagnosis, treatment, epidemiology, prevention and control, we call for more vigilance and awareness of the disease from governments, health authorities, clinicians, veterinary workers, nursing homes, and also the general public.

by Francis Galaway, Ryan Yu, Anastasia Constantinou, Franck Prugnolle, Gavin J. Wright Many important infectious diseases are the result of zoonoses, in which pathogens that normally infect animals acquire mutations that enable the breaching of species barriers to permit the infection of humans. Our understanding of the molecular events that enable host switching are often limited, and yet this is a fundamentally important question.Plasmodium falciparum, the etiological agent of severe human malaria, evolved following a zoonotic transfer of parasites from gorillas. One gene —rh5—which encodes an essential liga...

AbstractToxoplasmosis is a zoonotic food-borne disease with global distribution. The principal aim of this research was to detect the seroprevalence ofT. gondii infection in cattle, dogs and cats in dairy farms with high incidence of abortion, as well as to identify associated risk factors in Hamedan, Iran. A number of four large dairy farms with high history of abortion were selected and evaluated for risk factors associated toT. gondii infection. Blood samples were taken from 400 of pregnant cattle, 85 of dogs and 35 of cats (all of the dogs and cats population from interring and around of farms were sampled). The sample...

Trichinellosis is a globally-distributed zoonotic parasitic disease caused by nematode worms of the genus Trichinella. One of the most common species of Trichinella known to affect human health is T. britovi; however, it is relatively poorly investigated. A thorough knowledge of the proteins expressed by Trichinella is important when developing immunological detection methods and vaccines and studying its interactions with the host. The present study uses the Pichia pastoris expression system to produce a soluble TbCLP antigen which induces strong antibody responses in the host during natural infection. Our results demonst...

However, information about parasitic and bacterial infections in snakes from China is scarce. We investigated the prevalence of selected zoonotic agents including Cryptosporidium, Hepatozoon and Spirometra, in snakes in central China from June to October in 2018 by PCR amplification using parasite-sp...

AbstractGiardia intestinalis andBlastocystis spp. are two common zoonotic intestinal parasites responsible for the majority of diarrheic cases, especially in children. The study was planned to determine the impact role of bothGiardia andBlastocystis co-infection in children up to 12  years old with acute diarrhea in Beni-Suef, Egypt. Also, to estimate the general prevalence rates and risk factors associated with intestinal parasitic infections. Stool samples collected from 125 children, within a period of 7 months, were examined using direct wet mount and trichrome stain in c omparison to in vitro culture on Jone...
