Parasitic infections among patients hospitalized in the Tropical and Parasitic Clinic of Poznan University of Medical Sciences, Poland between 2015 and 2018. Is there a relationship between protozoa infection and gastrointestinal symptoms?

Introduction: Diarrhoea is a common reason for hospitalization among travellers returning from the tropics. The aetiology is predominantly bacterial, but it can also be caused by parasites such as spp., and spp.

Carbapenemase-producing Enterobacteriaceae in a group of Polish travelers returning from South and South-East Asia, June 2017 - June 2018. Environment- or healthcare-associated?

Introduction: Carbapenemase-producing have spread rapidly through the countries and continents to become a global concern. One of the main reservoirs of NDM-1 positive strains from the family is the Indian subcontinent (Bangladesh, Pakistan, India).

Material And Methods: During June 2017 - June 2018, rectal swab samples were collected routinely in all patients returning to Poland from South and South-East Asia.

Disseminated skin rash and blood eosinophilia in a Polish traveler diagnosed Strongyloides stercoralis, Trichuris trichiura, Schistosoma sp. and Blastocystis sp. coinfection.

Traveling to tropical countries make very often for travelers a danger of illnesses, which do not exist or exist very rarely in temperate climate. Imported parasitic disease cases are inevitable and have been reported increasingly as a result of enhanced globalization. The most common infections in endemic areas are caused by soil transmitted helminths.

Massive Cryptosporidium infections and chronic diarrhea in HIV-negative patients.

Protozoa of the genus Cryptosporidium are common parasites of domestic and wild animals-mammals, birds, reptiles, and fishes. The invasive forms are thick-walled oocysts, which can be present in water supplies, on fruits, vegetables, or in the soil contaminated with feces. In this work, we describe three cases of middle-aged persons with massive Cryptosporidium hominis infection and chronic diarrhea with no immunological abnormalities and no history of previous travels to tropical countries.

Cerebral malaria and multi-organ dysfunction in an adult woman with Plasmodium falciparum infection imported from Cameroon: a case report.

Malaria is one of the most life-threatening parasitic diseases caused by the protozoa of the genus Plasmodium, occurring in the tropical and subtropical regions. Misdiagnosed infection can progress to a wide range of life-threatening pathologies, including severe anemia and cerebral malaria which can lead to death even few days after first symptoms appearance. Cerebral malaria is rare in adults and most cases are connected to children under 5 years old living in malaria endemic areas.

Dirofilaria repens infection as a cause of intensive peripheral microfilariemia in a Polish patient: process description and cases review.

Dirofilariasis is a parasitic disease of dogs and other carnivores transmitted mainly by the mosquitoes of the genera Culex, Aedes, Anopheles. Full life cycle of the Dirofilaria nematodes in humans is extremely rarely observed, usually lacking species determination at the molecular level. We report fully documented unusual clinical manifestation of subcutaneous dirofilariasis with intensive microfilariemia in peripheral blood revealed by the Knott's concentration technique.

Intestinal coccidian parasites as an underestimated cause of travellers' diarrhoea in Polish immunocompetent patients.

Intestinal coccidian parasites are intracellular protozoa most frequently transmitted during food-borne and water-borne infections. This group of parasites is responsible for acute diarrhoeal illnesses especially among immunocompromised patients. However, they are more frequently detected in immunocompetent individuals including travellers, and they should also be considered as important etiologic factors of travellers' diarrhoea.
