Dogs were investigated to determine if they are definitive hosts of Neospora caninum. Four dogs were fed N. caninum tissue cysts in infected mouse tissue, and two negative control dogs were fed uninfected mouse tissue. Dog faeces were examined daily for 30 days using a sucrose flotation technique. Three challenged dogs shed spherical to subspherical(More)
OBJECTIVE To test the hypothesis that cats are definitive hosts of Neospora caninum. ANIMALS 6 weaned male kittens obtained from 2 sources, and several dozen outbred mice. PROCEDURE Cats were fed large numbers of 3 strains of N caninum: tissue cysts in buffered saline solution, mouse brain homogenates, and whole carcass homogenates from seropositive(More)
Dogs are a definitive host of Neospora caninum, a protozoal parasite that causes abortion in cattle. Mustelids were tested to determine if they could also be definitive hosts. The procedures used were the same as those previously used to test dogs. Ermine (Mustela erminea), weasels (Mustela frenata) and ferrets (Mustela putorius) were fed N.(More)
• The percentage of records for which the EDIS diagnosis matched the admitted patient data principal diagnosis was high for asthma (84%) and most types of injuries (average 75%). • 65% of admissions for poisoning also had a diagnosis code in the EDIS for poisoning. Many of those who did not have a poisoning code in the EDIS received codes relating to(More)
OBJECTIVE The aim of the present study was to assess the suitability of emergency department (ED) discharge diagnosis for identifying patient cohorts included in the definitions of key performance indicators (KPIs) that are used to evaluate ED performance. METHODS Hospital inpatient episodes of care with a principal diagnosis that corresponded to an(More)
Dogs are a definitive host of Neospora caninum and cattle are intermediate hosts. Alternative life-cycles have not been investigated. Foxes are frequently seropositive, but may not commonly prey upon cattle; therefore, other intermediate hosts may exist that are frequent prey of foxes. Three domestic pigeons (Columbia livia) and three zebra finches(More)
Pregnant ewes inoculated with cultured Neospora caninum tachyzoites in 1995, 1996, or 1995 and 1996 aborted or delivered weak or clinically normal lambs in 1996. Nine of 11 ewes in the study had previously produced infected lambs or fetuses after being experimentally infected in 1995. Fetuses and lambs produced in 1996 showed histologic lesions and zoites(More)
Like many yeasts, bacteria, and other sporulating microorganisms, Acanthamoeba castellanii (Neff), a free-living amoeba with pathogenic relatives, differentiates into a dormant form when deprived of nutrients. Acanthamoeba cysts redifferentiate into trophozoites when food is resupplied. We report here that Acanthamoeba encystment is also triggered by(More)
Chronic kidney disease (CKD) refers to all conditions of the kidney, lasting at least three months, where a person has had evidence of kidney damage and/or reduced kidney function, regardless of the specific diagnosis of disease or condition causing the disease 1. Five stages of CKD are defined and patients with end-stage kidney disease (ESKD) or stage 5(More)
