|
Definition
| Lactic Acid bacteria that ferment to produce only lactic acid as the end-product. A glycolytic pathway is used producing 2 ATP per Glucose. |
|
|
Term
|
Definition
| Lactic Acid Bacteria that produce not only Lactic acid as end-products through fermentation but also CO2 and Ethanol. Only 1 ATP per Glucose. |
|
|
Term
|
Definition
| A subgroup of Lactic Acid Bacteria and a non-sporulating gram positive bacterial group. Some are human pathogens divided into two groups: those with exotoxins and those w/o. The exotoxin is cytolytic and called streptolyson. |
|
|
Term
|
Definition
| A cytolytic exotoxin produced by streptoccocus bacteria from the Lactic acid group under the non-sporulating gram positive bacteria |
|
|
Term
|
Definition
| A bacterium infecting the respiratory tract and can become systemic, it belongs to the streptoccocus subgroup under LActic Acid Bacteria in the non-sporulating bacteria group. |
|
|
Term
| Non-exotoxin Streptoccocus |
|
Definition
| Infects the mouth and intestinal tract. Eg: S. mutans causes cavities in the teeth. |
|
|
Term
|
Definition
| Part of gram positive, non-sporulating, Lactic Acid Bacteria. It is homofermentative, acidophilic and associated with dairy. |
|
|
Term
| Lactobaccilus acidophilus |
|
Definition
| a producer of acidophillus milk. It is a species of Lactobaccillus. |
|
|
Term
| Lactobacillus delbrueckii |
|
Definition
| produces yoghurt,is a species of lactobacillus. |
|
|
Term
| Groups under streptoccocus |
|
Definition
| There are three: Lactococcus (dairy products), Enteroccocus (intestinal flora), and Streptoccocus (human pathogens). |
|
|
Term
|
Definition
| A group of gram posistive coccobacillus. They are homofermentative, microxic/aerobes and producce lactic acid through fermentation. They are non-sporulating (the group). |
|
|
Term
| Endospore Forming gram positive bacteria |
|
Definition
| A subgroup of gram + bacteria. Most live in the soil. There are two key genera: Bacillus and clostridium. |
|
|
Term
|
Definition
| A group of gram positive endospore forming bacteria. They are obligate/ facultative aerobes. in the stationary phase they produce antibiotics including: bracitiacin, polymyxn, and gramicidin. |
|
|
Term
|
Definition
| endospore forming gram positive bacteria in the group Bacillus. Their endospres can act as insecticides and they produce the B+ toxin. |
|
|
Term
|
Definition
| Anthrax bacterium, an endospore forming gram positive. It is a soli dweller, when cattle graze on contaminated soil they fall ill but rarely are humans affected. An AB toxin causes sickness and a BT protoxin can cause larvicide when the larvae eat it. |
|
|
Term
|
Definition
| There are three: cutaneous (endospores in an open wound), gastrontestinal (eating endospores), pulmonary (inhaled endospres, this is lethal) |
|
|
Term
|
Definition
| A key genus under endospore forming gram positive bacteria. Obligate anaerobes using fermentation. they are categorized based on the substrate for fermentation. |
|
|
Term
| Carbohydrate fermenting Clostridium |
|
Definition
| they produce C4 compounds, butyric acid, and butanol. these are gram positive endospore forming bacteria. |
|
|
Term
| Amino acid fermenting Clostridium |
|
Definition
| Stinky products: H2S, CH3SH, cadaveran. they are anaerobic so tend to live in anoxic pockets of flesh (dead carcasses) created by aerobes. |
|
|
Term
|
Definition
| a gram positive endospore forming bacterium found in the large intestine and can be transmitted through fecal contamination.Tends to be in hospitals after gut flora are wiped out by antibiotics and it takes over causing diarrhea. |
|
|
Term
|
Definition
| A gram positive endospore forming bacterium that produces the botulism toxin which is an AB toxin. |
|
|
Term
|
Definition
| Produced by C. botulinum and is the most deadly toxin known. It is an AB, causes flaccid paralysis by inhibiting acetylcholine so no more muscular contractions. |
|
|
Term
|
Definition
| The causes tetanus and is a gram positive endospore forming bacterium. |
|
|
Term
|
Definition
| An AB exotoxin that causes spastic paralysis by preventing vesicles in the nueromuscular junction from delivering compunds that would remove acetylcholine from the receptor. So the muscle contracts and cannot release. |
|
|
Term
|
Definition
| This gram positive endospore forming bacterium causes gas gangrene. This is done through two proteins. A cytolytic exotoxin (lecithinase) and collagenase which breaks down collagen in tissues. the gangrene spreads in this way. (necrotic tissue). |
|
|
Term
| Causes of gas gangrene infection |
|
Definition
| Clostridium Tetani enters your flesh when it is anaerobic eg: if frostbitten or diabetic so that the extremities lose blood circulation. the condition of the tissue is perfect for them. |
