1. A preliminary survey of viruses of bats of Canada (identification of viruses that might emerge as human pathogens)

2. Emerging infectious diseases (EID) pathogen infects host for the first time new strains of a pathogen with distinct properties increased incidence of preexisting disease new or reintroduction into area

3. Animals and emerging human disease most EID events emerge from animals most of these events (70%) involve wild animals nature 21 Feb 2008

4. Role of bats in EID Confirmed or suspected in: –Nipah –Hendra –SARS –Marburg –Ebola –Menangle –Tioman –Melaka –rabies (in some areas)

24. remove liver, kidney, brain, spleen, lung, intestine fix in formaldehyde (pool tissues from same species of bats) homogenize (pooled tissues) freeze at -80 tissue culture (primate, rodent bats, avian cells) Purify nucleic acid QIAmp viral RNA mini kit (will purify RNA and DNA) cDNA synthesis PCR corona (Gr 1, pan) lyssa henipah morbilli WNV Hanta gel sequence observe daily for cpe + - amplify characterize 3 passages autoclave +- herpes polyoma flavi bunya alpha Cache Valley
