Rules in gram staining?
All cocci are gram (+) except Neisseria, Branhamella, Moraxella and Veilonella. All bacilli are gram (-) except Mycobacterium, Corynebacterium, Lactobacillus, Listeria, Clostridium, Bacillus, Erysipelothrix, and Nocardia. All spirals are gram (-)
What is a gram positive aerobic bacteria which uses citrate and dextrose?
I think that there are two possible answers....first, Nocardia and, also, Bacillus anthracis. Lactobacillus might also work; however it is a microaerophilic organism and can only tolerate lesser levels of oxygen than a true aerobic organism. But all three are gram positive and, I believe, thrive with both dextrose and citrate. Nocardia has a Trycarboxylic acid cycle which utilizes both dextrose and citrate.
What are some examples of Aerotolerant bacteria?
Clostridium tetani is an example of an obligate anaerobe. It can survive as a spore in the presence of oxygen, however, vegetative cell growth can only happen in the absence of oxygen. This is why puncture wounds are more likely to result in tetanus (disease caused by C. tetani) than a scrape.A common facultative anaerobe is Staphylococcus aureus, which is part of the normal bacterial flora of human skin.
How is nocardiosis diagnosed?
Nocardia is not easily identified from cultures of sputum or discharge. A doctor can diagnose the condition using special staining techniques and taking a thorough medical history. Lung biopsies or x rays also may be required.
What is the bacteria mophology for bacillus subtilis by simple stain?
B. subtilis is indeed a Gram positive rod.However, there is confusion as to whether it is an obligate aerobe or a facultative anaerobe. Although classed as an obligate aerobe, it has been shown to grow under strict anaerobic conditions.
What lacks a cell wall borrelia mycoplasma mycobacteriu clostridium nocardia?
mycobacterium
What is an example of a parasitic bacteria?
There are many different types of parasitic bacteria in the world. Some of these include Brucella, Legionella, Mycobacterium, and Nocardia.
Aside from the genus Mycobacterium name other groups of microorganisms which are considered as acid-fast or partially acid-fast?
NocardioformsNocardioforms include nine genera of aerobic, acid-fast rods, including members of the genus Nocardia. Nocardioforms have aerial hyphae which project above the surface of their growth medium as branching filaments. The hyphae fragment into rods and cocci. Nocardioforms are found throughout nature in many types of soil and aquatic environments. One species, N. asteroides, causes infection of the human lung.

Does nocardia have mycolic acid?
Yes
Can nocardia be transmitted to humans by cats?
Yes.
What are results for a acid-fast test for enterobacter aerogenes?
Enterobacter aerogenes is a non-acid fast bacteria. Bacteria only in the Mycobacteria and Nocardia genus are acid fast.
What are the causes of nocardiosis?
Nocardiosis is caused by a bacterium of the Nocardia species--usually N. asteroides, an organism that is normally found in the soil. The incubation period is not known, but is probably several weeks.

What is a Gram positve and negative stain?
Gram stain is used to determine whether the cell is gram positive or negative. Gram positive is when the cell has very thick layers of peptidoglycan, and gram negative when the layers are thin. In the staining process, those that decolorize easily are gram negative, and the one that retain the primary stain are gram positive. The acid fast staining is a techique that stains only the gram positive and only the genuses of mycobacterium, nocardia, and actinomycetes.
