1. Reproduction of bacteria
(a) Conjugation - the two bacteria need to conjugate (means need physical contact) through pila (conjugation tube)
(b) Transduction - a bacteria is transduced with another's DNA by bacteriophage
(c) Transformation - a bacteria simply take up the DNA of another bacteria from the vicinity

2. I also could not find a good formula myself but it was kind of helpful studying from the NBDE first aid (table 18.4 pg. 438).

3. Toxoid = toxin like (not true toxin). Toxoid have antigenicity but do not have harmful effect like toxin. The antigenicity of the toxiod can induce acquired active immunity (means need time).
Anti-toxin = conteract toxin. They are preformed antibody which will neutralized the toxin (acquired passive immunity in a short time).
So, to warp up toxin, toxoid and anti-toxin are different :). Hope it is helpful for your study.

3- toxoid: modified TOXIN (usec to activate immnue system)
anti-toxin: ANTIBODY (used to neutralize toxin)

Hi OMFS,
For obligate aerobes it is Nagging Pests Must Breathe-- Nocardia,pseudomonas,mycobacterium,Bacillus
for obligate anaerobes the mnemonic is ABC-- Actinomyces,Bacteroides and Clostridium.For Hemolytics--It is alpha,beta and gamma which is almost,best and garbage.Alpha there is partial breakdown of heme,hence almost.Beta there is completele lysis hence best and Gamma there is no hemolysis hence garbage.TC
