How do you treat bacilli?
Infections with B. anthracis can be treated with β-lactam antibiotics such as penicillin, and others which are active against Gram-positive bacteria. Penicillin-resistant B. anthraciscan be treated with fluoroquinolones such as ciprofloxacin or tetracycline antibiotics such as doxycycline.
Why are broad-spectrum antibotics often used to treat infections caused by unidentified pathogens?
Broad-spectrum antibiotics are used to treat unidentified pathogens because they are active again gram positive and negative bacteria.Certain antibiotics can treat only gram negative or positive bacteria.When bacteria is unidentified doctors must choose an antibiotic that work for all types of bacteria.
What are the 3 difference between Active and Inactive bacteria?
Active bacteria are metabolically active and capable of growth and replication, while inactive bacteria are dormant and not actively growing. Active bacteria are more susceptible to antibiotics and disinfectants, while inactive bacteria are more resistant. Active bacteria can cause infections and illnesses, while inactive bacteria do not pose an immediate health risk.
What does antibactrial mean?
Active against bacteria.
What kind of antibiotics are effective against anaerobic pathogens?
the lincosamindes, clindamycin and lincomycin, which are highly active against anaerobic pathogens
Is metronidazole gram negative or positive?
It has an effect on both gram negative and gram positive bacteria, however it only affects anaerobic bacteria, not aerobic. It has severe adverse effects when consumed with alcohol.
What is antibiotics and his function?
An antibiotic is a type of antimicrobial substance active against bacteria. It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections.

Is penicillin active against gram positive?
No, aminoglycocides are used
What bacteria does gentamicin kill?
Gentamicin is effective against a variety of Gram-negative bacteria, including Escherichia coli, Pseudomonas aeruginosa, and Klebsiella pneumoniae. It is also active against some Gram-positive bacteria such as Staphylococcus aureus. However, resistance to gentamicin is becoming more common among certain bacterial strains.
What phase is most susceptible to antibiotics?
It is the exponential phase. Many antibiotic such as the Streptogramin family work on the ribosome and indeed the DNA and RNA polymerases. These are most active when the bacteria are dividing and so it causes more harm as it were. Also in Mycobacterium, when dividing it does not have such a thick cell wall, and so it is easier for the antibiotics to penatrate that is true, also known as the Log phase and is when an organism is most sensative to antibiotics like penicillin-
What role have doctors played in the emergence of antibiotic restistance?
Patients often demand antibiotics when they have colds, flus, or other viral illnesses, even though antibiotics do nothing for these conditions. When doctors give in to these demands, they contribute to antibiotic resistance. It's important to understand how antibiotics work, and how bacteria respond to them. Each time an antibiotic is taken, bacteria respond by making adjustments in how they breed. It's much like watching a linebacker in a football game as he uses fast footwork to weave and sway to get around an opponent. As the bacteria changes how it produces, it "weaves and sways" and "goes around" the active ingredients in antibiotics. Each time a bacteria encounters that same bacteria, it now has new defenses to defeat the antibiotic. Since most antibiotics belong to "families" of antibiotics with similar properties, the defenses a bacteria creates against one antibiotic often will now defeat the entire "family" of similar antibiotics, kind of like how one football team (here a bacteria type) can defeat another football team (here a family of antibiotics). Since we need to know one or a different antibiotic will be able to defeat a certain bacteria, we need to limit how often we take any antibiotics.
