Why should swabs be avoided when collecting specimens for anaerobic culture?
cotton fibers may be detrimental to anaerobes. Abscesses or fluids can be aspirated using a sterile syringe that is then tightly capped to prevent entry of air.
Is mycoplasma aerobes or anaerobes?
most of them are facultative anaerobes. oxygen is not pioson for them. M. pneumoniae is aerobe. there are also some strict anaerobes in bovine rumen.
Bacteria that only grows with the absence of oxygen?
Bacteria that can ONLY grow in the absence of oxygen are called obligate anaerobes.
Can obligate anaerobes grow on a slant that is incubated anaerobically?
Do obligate anaerobes grow on a slant if they are incubated anaerobically?
What is associated with methanogens?
Anaerobes is associated with methanogens.
What types of specimens should always be cultured for anaerobes if an infection is suspected?
These include abscesses, bites, blood, cerebrospinal fluid and exudative body fluids, deep wounds, and dead tissues. The specimen must be protected from oxygen during collection and transport
Why can media such as brain-heart infusion and thioglycollate be used for the cultivation of anaerobes?
Anaerobes cannot be cultivated in the presence of atmospheric oxygen.
Historically the sociological perspective was most likely to develop in?
isolated villages
Why will obligate anaerobes grow in thioglycollate?
Obligate anaerobes do not need or use oxygen as a nutrient. In fact it is a toxic substance to them which either kills or inhibits their growth. Thioglycollate allows obligate anaerobes to grow because it consists of sodium thioglycollate, thioglycollic acid and L-crystine which reduce oxygen to water. This creates an anaerobic environment allowing obligate anaerobes to grow.
Bacteria that survive with or without oxygen are known as?
There are two groups of organisms that are capable of thriving in an environment without oxygen. Facultative Anaerobes Anaerobes Facultative means with or without.
What organisims do not need oxygen to survive?
