Abstract
This study aimed to determine the presence of cryptosporidiosis in immunosuppressed patients hospitalized at the Clinic of Haematology and Oncohaematology in a form of routine screening. Samples were collected from November 2019 to February 2020, when the first wave of the Coronavirus pandemic occurred in Slovakia. A total of 36 samples were collected from patients hospitalized at the Clinic of Haematology and Oncohaematology, both from the open ward and the intensive care unit. For the diagnosis of cryptosporidiosis, a nested PCR targeting the gp60 gene and the SSU rRNA locus was used. From the 36 samples, Cryptosporidium parvum subtype IIaA17G1R1 was diagnosed in 9 patients (7 from the open ward and 2 from the intensive care unit), all hospitalized at the clinic at the same time, in February 2020. The occurrence of the same species and subtype, Cryptosporidium parvum IIaA17G1R1, in 9 patients hospitalized at the same time, both at the open ward and the intensive care unit may suggest a possible transmission occurred at the clinic.
