Aseptic technique

the method of handling microbes and materials in a way that minimizes contamination

2

inoculation

process of transferring a microbe from one medium to another

3

Inoculum

sample being transferred during inoculation

4

inoculating loop/needle

tools used to transfer bacteria from a culture to sterile media.

5

isolation streak plate

wide method to separate individual bacteria from mixtures

6

The goal of a streak plate is ?

to thin out the number of bacteria on a plate to get isolated colonies

7

Spread-plate method

sample is pipetted onto the plate; spread evenly with a glass spreader

8

Pour-Plate method

sample is pipetted into the plate and then sterile is poured into the membrane

9

Agar

provides a solid surface to grow bacteria; from seaweed; Koch developed it

10

Incubator-

12

Epidemiology

The study of how a specific infectious agent survives and spreads through a community

13

Disease Transmission

The actual way the infectious agent spreads

14

Direct transmission

Biological vectors; or hand holding, shaking and kissing

15

Entranceway through which a specific microbe is able to invade a host

16

-Gastrointestinal tract
-Respiratory tract
-Conjunctiva
-Skin Urogenital tract (STD) ---Pregnancy and birth

17

Reservoir of infection

Any object, living or nonliving, that allows a microbe to grow, reproduce, and maintain its ability to remain infective

18

fomites

a nonliving object capable of allowing a microbe to survive but not reproduce

19

what controls fomites?

Proper and consistent hand washing controls fomite transmission
