Q

HOW DO BACTERIUM BUILD A RESITATNCE?

A

BY EXCHANGING PLASMINDS RESULTING IN MULTI DRUG RESISTANT STRAINS OF BACTERIUM

20
Q

DO SOME BACTERIA PRODUCE ENDOSPORES?

A

YES

21
Q

WHAT ARE ENDOSPORES?

A

THICK WALLED STRUCTURES THAT CONTAIN A COPY OF THE CHROMOSONE CYTOPLASAM

22
Q

WHAT DO ENDOSPORES DO?

A

ALLOW BACTERIA TO TO SURVIVE IN ADVERSE ENVIRONMENTS

23
Q

HOW DO ENDOSPORES WORK?

A

WHEN THEY LAND IN A SUITABLE ENVIRONMENT THEY GERMINATE TO PRODUCE NEW BACTERIUM

A

MICROBES THAT CAUSE DISEASE - ABOUT 3% OF MICROBES ARE PATHOGENIC

43
Q

WHAT ARE NON PATHOGENS?

A

MICROBES THAT DO NOT CAUSE DISEASE

44
Q
