Genetic characterization of Cryptosporidium species from humans in Spain

Prevalence and genotyping ofCryptosporidiumisolated from HIV/AIDS patients in urban areas of Thailand

“…We could successfully identify Cryptosporidium species from HIV/AIDS-positive patients in 16 samples with C. hominis, 12 samples with C. parvum infection, 3 samples with C. meleagridis, 1 sample with C. felis and 1 sample with an infection of C. canis. In our study, C. hominis has been slightly more Llorente et al (2007). Not only C. hominis infects humans, but it has been also found in animals such as dugongs, lambs and cattle (Smith et al, 2005).…”

Genotyping of Cryptosporidium isolates from human clinical cases in Poland

“…One case of Cryptosporidium infection was also identified in a patient from the Institute of Oncology (group 3). Similar high rates of Cryptosporidium infection in immunocompetent children with chronic diarrhoea were confirmed recently in Poland (Golab et al 2007) and in other countries worldwide (Ajjampur et al 2007;Llorente et al 2007;ten Hove et al 2007;Sanad and Al-Malki 2007). High prevalence of Cryptosporidium infection in individuals with primary and secondary immunodeficiencies, exceeding even 82% in patients with AIDS and chronic diarrhoea, is commonly found in clinical practise (Winkelstein et al 2003;Sanad and Al-Malki 2007).…”

“…In this group, C. parvum was detected in two cases and C. hominis and C. meleagridis were identified in the remaining two cases (Wolska-Kuśnierz et al 2007). In other studies, up to eight different Cryptosporidium species/ genotypes were identified in immunocompetent and immunodeficient children, including the mouse and cervine genotypes of C. parvum as well as C. meleagridis, Cryptosporidium felis, Cryptosporidium canis and Cryptosporidium muris (Pedraza-Diaz et al 2001b;Xiao et al 2001;Soba et al 2006;Ajjampur et al 2007;Gatel et al 2007;Llorente et al 2007). In contrast with the first group of patients, those within group 2 suffered from disseminated infection with symptoms of inflammation of the bile duct and gall bladder.…”

Evaluation of Four Commercial Rapid Immunochromatographic Assays for Detection of Cryptosporidium Antigens in Stool Samples: a Blind Multicenter Trial

“…However, considerable progress has been made in the molecular characterization of Cryptosporidium since the development of these tests, resulting in the identification of at least seven human-infecting species (3,18). Cryptosporidium parvum and C. hominis remain the two most frequent species detected with various levels of prevalence in different countries (2,6,7,12,15,17) but with a high (up to 90%) predominance of C. hominis in tropical and developing countries (1,4,5,18). Species other than C. parvum and C. hominis have also emerged as causes of cryptosporidiosis in both immunocompromised and immunocompetent patients (2,4,5).…”
