Neutrophils do not mediate the pathophysiological sequelae of Cryptosporidium parvum infection in neonatal piglets.
Cryptosporidium parvum is a minimally invasive protozoal pathogen of intestinal epithelium that results in villus atrophy, mucosal lipid peroxidation, diarrhea, and diminished barrier function. Influx of neutrophils is a consistent feature of human and animal cryptosporidiosis, and yet their contribution to the pathological sequelae of infection has not been investigated. Accordingly, we used a...
متن کاملExperimental infection of lambs with Cryptosporidium isolated from a human patient with diarrhoea.
An inoculum containing Cryptosporidium oocysts obtained from an adult human patient with acute transient diarrhoea induced enteritis in two newborn specific pathogen free lambs. Three days after inoculation the lambs became depressed and diarrhoeic, their milk intake was reduced and Cryptosporidium oocysts were detected in their faeces. Mucosal changes observed in the small intestine of one inf...
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 کاملEffects of porcine circovirus type 2 (PCV2) maternal antibodies on experimental infection of piglets with PCV2.
To determine the effects of porcine circovirus type 2 (PCV2) maternal antibodies on and response to experimental PCV2 infection, 24 piglets were divided into four groups on the basis of the enzyme-linked immunosorbent assay titers of PCV2 maternal antibodies: group A (n = 6; sample/positive [S/P] ratio, <0.2), group B (n = 5; S/P ratio, >0.2 to <0.5), and groups C (n = 8) and D (n = 5) (S/P rat...
متن کاملExperimental enteric infection of gnotobiotic piglets with Chlamydia suis strain S45.
Enteric chlamydial infections of pigs with Chlamydia (C.) suis are frequent and often subclinical. The enteric pathogenicity of C. suis strain S45 was investigated in gnotobiotic piglets. Piglets from three litters (n=31) were inoculated with egg-grown chlamydiae at 2-3 days of age (n=17) or used as controls (n=14). They were observed for clinical signs, killed and necropsied sequentially at 2-...
