Veterinarians are are Microorganism Microorganism Detectives Detectives
Today you are the Vet Loki has a nasty cough! You must use your detective skills to work out what is making him sick
Suspect Microbe No. 1 : The Virus Really, really small electron microscope Can only grow and multiply inside living cells Vaccinations exist for some viral diseases Feline Herpes Virus Feline Herpes Virus Size: 1/10 of a micrometer
Suspect Microbe No. 2 The Bacteria Single cells, no nucleus They are everywhere, and sometimes cause disease Bordatella Bordatella bronchiseptica bronchiseptica 8/10 micrometer long
Suspect Microbe No. 3 The Fungus Fungi include single-celled organisms and also mushrooms! Have cell walls and nucleus There are over 2 million different fungi Cryptococcus Cryptococcus neoformans neoformans 5-10 micrometers in diameter
Suspect Microbes No. 4 Parasites O Protozoa one cell - tummy and blood O Worms O eggs, larvae and adults O Have many body systems complex Cat lungworm larvae Cat lungworm larvae Aelurostrongylus Aelurostrongylus abstrusus abstrusus 300 micrometers long, kinked tail
