You will probably need a blood enriched plate to grow these organisms,
at least from my experience in clinical microbiology. I'm not sure about
the A. naeslundii - it may need something richer like brain heart
infusion with blood. Also, you may need CO2 enrichment. Lactobacillus
species don't grow very fast - not sure about caseii.
Are you doing colony counting or just streaking for isolation?
