Effect of C. Parvum on immunization with irradiated tumour cells [PDF]

open access: yesBritish Journal of Cancer, 1976
S.c. injection of tumour cells or small pieces of tumour irradiated to a dose of 22,000 rad evoked resistance to live challenge with the same tumour (a CBA strain fibrosarcoma induced with methylcholanthrene) 14 days later. This resistance was, however, over-ridden if the challenging inoculum was sufficiently large, and did not develop if the cells ...

Immunological mechanisms in metastatic spread and the antimetastatic effects of C. parvum [PDF]

open access: yesBritish Journal of Cancer, 1977
The effects of the host's immune response on metastatic spread was investigated by observing the numbers of pulmonary metastases that developed from an s.c. implant of the Lewis lung carcinoma in C57BL mice in which different cell populations had been suppressed. Macrophage function was impaired by treatment with silica (Si), cortisone acetate (CA), or

PCR-RFLP analysis of the Cryptosporidium oocyst wall protein (COWP) gene discriminates between C. wrairi and C. parvum, and between C. parvum isolates of human and animal origin [PDF]

open access: yesFEMS Microbiology Letters, 2006
Cryptosporidium wrairi was isolated from guinea pigs during a spontaneous outbreak of cryptosporidiosis. Despite the morphological and antigenic similarities to C. parvum, C. wrairi displayed a different host range and site of infection and may represent a separate species or sub-species.

Abrogation of the anti-metastatic activity of C. parvum by antilymphocyte serum [PDF]

open access: yesBritish Journal of Cancer, 1976
Corynebacterium parvum (C. parvum) can cause a significant reduction in the growth of both primary tumours and their metastases (Sadler and Castro, 1976; Proctor, Rudenstam and Alexander, 1973; Woodruff and Boak, 1966). When consideration is given to the

Distribution and clinical manifestations of Cryptosporidium species and subtypes in HIV/AIDS patients in Ethiopia. [PDF]

open access: yesPLoS Neglected Tropical Diseases, 2014
BACKGROUND: Cryptosporidiosis is an important cause for chronic diarrhea and death in HIV/AIDS patients. Among common Cryptosporidium species in humans, C. parvum is responsible for most zoonotic infections in industrialized nations.

Population genetics of Cryptosporidium parvum subtypes in cattle in Poland: the geographical change of strain prevalence and circulation over time

open access: yesBMC Veterinary Research, 2022
Highlights C. parvum subtypes from the IIa allele family predominated in the tested cattle. The prevalence of C. parvum subtypes in cattle was breed-related. Dynamicity in the population C. parvum strains circulating in cattle was shown.

C3a/C3aR Affects the Propagation of Cryptosporidium parvum in the Ileum Tissues of Mice by Regulating the Gut Barrier, Cell Proliferation, and CD4+ T Cell Main Effectors

open access: yesAnimals, 2023
Cryptosporidium parvum is an important zoonotic protozoon that threatens the health of humans and animals, but the interaction mechanisms between C. parvum and hosts are poorly understood.

Detection of Cryptosporidium parvum oocysts in calf fecal samples by direct immunofluorescence assay Detecção de oocistos de Cryptosporidium parvum em amostras fecais de bezerros pela reação de imunofluorescência direta

open access: yesRevista Brasileira de Parasitologia Veterinária, 2011
The aim of this study was to produce a conjugate containing anti-Cryptosporidium parvum polyclonal antibodies and standardize a Direct Immunofluorescence Assay (DIF) for detecting C. parvum oocysts in fecal samples from calves. In order to obtain anti-C.

Cryptosporidium Priming Is More Effective than Vaccine for Protection against Cryptosporidiosis in a Murine Protein Malnutrition Model. [PDF]

open access: yesPLoS Neglected Tropical Diseases, 2016
Cryptosporidium is a major cause of severe diarrhea, especially in malnourished children. Using a murine model of C. parvum oocyst challenge that recapitulates clinical features of severe cryptosporidiosis during malnutrition, we interrogated the effect ...
