Anti-microbials

• What form of antimicrobial is amoxycillin?

  Bactericidal
• Mode of action of Amoxycillin?

  Inhibits synthesis of a layer of bacterial cell wall during cell division. Affects bacterial survival as Bacterium are unable to maintain osmotic pressure, then swell and eventually rupture.
• When is amoxicillin used?

  To treat soft tissue infections, urinary tract infections.
• Characteristics of amoxycillin?

  Achieves high concentrations in kidneys, lungs and liver.

  
  

  Cannot cross BBB.
• What is amoxycillin?

  A broad spectrum antibiotic, used to treat a range of gram +ve and -ve bacteria.
• What type of antimicrobial is Cephalexin + Its family?

  Bactericidal, cephalosporin family.
• What is the mode of actions for cephalexin?

  Interrupts bacterial wall synthesis leading to bacterial lysis and cell death during dividing stage.
• When is cephalexin used?

  To treat soft tissue, skin, lung and urinary infections.
• what are some side effects of cephalexin?

  Hypersensitivity reactions, e.g. skin reactions.
• What type of antimicrobials and its family is oxytetracycline?

  Bacteriostatic, tetracycline family.
• What is the mode of action for oxytetracycline?

  Drug is absorbed by bacteria and inhibits bacterial protein synthesis by binding to ribosomes. Thereby, preventing multiplication and growth.
• What is oxytetracycline?

  A broad spectrum activity for gram +ve and -ve.
• what is oxytetracycline used to treat?

  Soft tissue and respiratory infections.
• what are some side effects of oxytetracycline?

  GI issues e.g. vomiting and diarrhoea.
• What is a contra-indication for oxytetracycline?

  Care in young animals, can stain enamel of teeth as it pulls calcium away from bones.
• What is the exact mechanism of interferon?

  To enhance the immune response of animals.
• What is the mode of action of Interferon?

  It protects the cell from viral invasion by making the host resistant and stimulates the immune system cell production. Stops replication of viral cells by destroying mRNA and inactivating translation of proteins.
• when is interferon used?

  to treat canine parvovirus infection and cats with FeLV.
• How does interferon treat canine parvovirus?

  parvovirus multiplies in rapidly dividing cells, interferon suppresses cell division and inhibits viral replication.
