Intestinal epithelial cell apoptosis following Cryptosporidium parvum infection.
Cryptosporidium parvum induces moderate levels of apoptosis of cultured human intestinal epithelial cells, which are maximal at 24 h after infection. Apoptosis is further increased in C. parvum-infected cells by inhibition of NF-kappaB. C. parvum infection also attenuates epithelial apoptosis induced by strongly proapoptotic agents. The data suggest C. parvum has developed strategies to limit a...
متن کاملIntestinal co-infection by Cyclospora sp. and Cryptosporidium parvum: first report in an AIDS patient.
Cyclospora is recently described new human pathogenic coccidian causing intermittent diarrhoeal enteritis which may persist for weeks or months in immunocompetent subjects, particularly travellers visiting some tropical areas and countries, such as Nepal, the Caribbean, Peru and Mexico. More rarely this enteric pathogen affects immunocompromised humans, namely HIV-infected people or AIDS patien...
متن کاملCryptosporidium parvum and Cryptosporidium andersoni infection in naturally infected cattle of northwest Iran
The protozoan intestinal parasite Cryptosporidium commonly infects cattle throughout the world and Iran. The present study was undertaken to determine the abundance and associated risk factors of Cryptosporidium infection in cattle herds of northwestern Iran. A total number of 246 fecal samples from 138 (56.1%) diarrheic (D) and 108 (43.9%) non-diarrheic (ND) cattle were rando...
متن کاملStrategies for the control of Cryptosporidium parvum infection in calves.
Cryptosporidium parvum is a protozoan parasite that is now recognized as one of the leading causes of diarrhea in young calves. To date, there are no drugs or preventive measures available for the control of this disease. We have developed an oral vaccine that, when given to calves at birth, protects against experimental challenge with C. parvum. However, when field tested on a large dairy oper...
متن کاملINTESTINAL AND PULMONARY INFECTION BY Cryptosporidium parvum IN TWO PATIENTS WITH HIV/AIDS.
We describe two patients with HIV/AIDS who presented pulmonary and intestinal infection caused by Cryptosporidium parvum, with a fatal outcome. The lack of available description of changes in clinical signs and radiographic characteristics of this disease when it is located in the extra-intestinal region causes low prevalence of early diagnosis and a subsequent lack of treatment.
