Dairy Foods Science Notes (D raft 06 - 10) The Microscopic Examination of Milk Characterization of Milk Bacteria and Cells The microscope has been used to observe and count bacteria and somatic cells Acinetobacter calcoaceticus A. lwoffiand A. anitratusmostly occur as short coccobacilli in cultures. They resemble diplococci and may sometimes be mistaken for Neisseria(Gram stain). Actinobacillus ac 1078 1079 separated into two tubes; one tube contained anticoagulant for hematology studies, and in other tube without anticoagulant was used for serum separation and subsequent biochemical tests.
