Is MacConkey Agar rich or minimal?
MacConkey’s is a selective medium that inhibits the growth of Gram-positive bacteria due to the presence of crystal violet and bile salts. Gram-negative bacteria grow well on MAC.
What types of bacteria grow on blood agar?
Blood Agar is used to grow a wide range of pathogens particularly those that are more difficult to grow such as Haemophilus influenzae, Streptococcus pneumoniae and Neisseria species. It is also required to detect and differentiate haemolytic bacteria, especially Streptococcus species.
Can bacteria digest agar?
bacterium that is capable of digesting agar. Behavior of the Agar-digesting, Luminous Bacterium, FLB-17, on the NC Agar Medium-. The inoculated agar medium was incubated at 2SOC for 48 hours. The cells digested agar.
Can virus be cultured in lab?
Cultivation of Viruses. Viruses can be grown in vivo (within a whole living organism, plant, or animal) or in vitro (outside a living organism in cells in an artificial environment, such as a test tube, cell culture flask, or agar plate).
Why viruses Cannot grow on artificial media?
Unlike bacteria and other microorganisms which can be grown in artificial media, viruses cannot be grown on artificial media but must be grown in living cells. Viruses cannot be grown on an ordinary culture medium because they are not actually living organisms. Animal and plant viruses are cultivated in cell cultures.
Why do antibiotics not work against viruses quizlet?
Taking too many antibiotic drugs can cause your body to develop a resistance to the drugs. Why do antibiotic drugs not work against viruses? Antibiotic drugs attack the parts of bacteria that viruses do not have, such as a cell wall. Since viruses do not have a cell wall, the antibiotic cannot affect it.
Why Antibiotics Cannot kill virus?
Viruses don’t have cell walls that can be attacked by antibiotics; instead they are surrounded by a protective protein coat. Unlike bacteria, which attack your body’s cells from the outside, viruses actually move into, live in and make copies of themselves in your body’s cells.
Why Antibiotics are used to treat bacterial but not viral diseases?
Antibiotics are useless against viral infections. This is because viruses are so simple that they use their host cells to perform their activities for them. So antiviral drugs work differently to antibiotics, by interfering with the viral enzymes instead.
Which antibiotic is best for viral infection?
The drugs used for viral infection are Acyclovir (Zovirax), famciclovir (Famvir), and valacyclovir (Valtrex) are effective against herpesvirus, including herpes zoster and herpes genitalis.Drugs used for treatment for viral fever are Acetaminophen(Tylenolothers)ibuprofen (Advil,motrin IB others).
