3. Combination of the two plasmid is called R-Factor
4. Many Gram (-) organisms acquire resistance to multiple antibiotics by conjugation mechanism. Multiple drugs resistant Enterobacteriaceae became a serious world-wide problem.
c) Host defense mechanism: A chemotherapeutic regimen that is perfectly adequate for immuno-competent patient may be totally ineffective for immuno-incompetent patient. Immunoincompetence may be due to deficiencies in (1) immunoglobulin, (2) phagocytic cells and (3) cellular immune
properties of antibiotics.

EFFECTIVENESS OF COMBINATION THERAPY
1. Synergistic Effect: When two bactericidal antibiotics are used in combination. One of the two drugs must show at least 4-fold increase in antibacterial activities (or a decrease in MIC to ¼) for a synergism is said to exist between the two drugs. (e.g. penicillin + streptomycin).
concomitantly). 4. Host determinants that influence the selection and
efficacy of antibiotics.

OBJECTIVES:
-Lactams constitute one of the most important and most frequently used groups of antibiotics available to combat infectious diseases. Therefore, all practitioners in any field of medicine should be knowledgeable of all aspects of the pharmacology. Particular attentions should be directed to the following:

2. Additive Effect: When two bacteriostatic agents with the same mechanisms of action are used.
3. Antagonism: Usually bacteriostatic antibiotics are antagonistic to bactericidal agents. (e.g. Chloramphenicol has been shown to antagonize the bactericidal activities of penicillin in the treatment of Pneumococcal meningitis.

Important Host Determinants
a) Hepatic function: Erythromycin, clindamycin, rifampin, Chloramphenicol, etc depend on liver metabolisms for the inactivation of antimicrobial mechanisms. Patients with impaired liver function may accumulate in the body active form of the drugs to a toxic level if the dosage adjustment is not made.
Cephalosporins: First Gen.:
cephalexin; cephalothin
Second Gen.: cefoxitin; cefaclor
Third Gen.:
cefotaxime; cefoperazone;
ceftriaxone
Fourth Gen.: cefepime
2. The transferable materials consist of two different DNA sequences: (1) R Determinant Plasmid for resistance mechanism (2) Resistant Transfer Factor (RTF) that is needed for conjugation.
1. Important pharmacodynamics and pharmacokinetics of the prototypes listed below.
2. Important therapeutic and prophylactic uses and untoward effects of prototypes that are representatives of different categories of -lactams.
INTRODUCTION TO ANTIMICROBIAL CHEMOTHERAPY (General Principles)
OBJECTIVES:
General principles of chemotherapy for other drugs govern antimicrobial chemotherapy also. However, there are principles that are more pertinent to the use of antimicrobial agents as a group. Particular attentions should be directed to the following:
