Hemolytic anemia, myelodysplasia, and liver disease may each fit this peripheral blood picture. Each of theseconditions can display peripheral blood macrocytosis. It is easy to observe the overall larger size of the redblood cells in this image compared to the normal lymphocyte also present.When macrocytes are present, they should be examined for their shape (round vs. oval), the hemoglobincontent (central pallor), and whether or not there are any inclusions present in the cell.Iron deficiency would not be the correct answer in this case, since this condition is associated withmicrocytosis instead.The complete blood count was obtained from a patient recently admitted to the emergency room. The redblood cell indices obtained revealed an MCV of 115 femtoliters (fL) (normal range 80 - 90 fL). The patientmet the criteria for a peripheral blood smear examination. A representative field is shown on the right

The clue to the identification of the colony seen in the upper frame is the gram stain in the lower frame, in
which are seen short, rounded, gram positive bacilli, many of which possess distinct spores. As the colonies
grew aerobically, the presence of spores indicates Bacillus species. The colonies are spreading, smooth,
yellow-white and non-hemolytic. The lack of hemolysis and the small size of the bacterial cells suggests a
species other than Bacillus cereus, the species causing most human infections. The isolate was identified as
Bacillus circulans, which is consistent with the gram stain morphology. Clostridium septicum also produces
spores; however, this species is an anaerobe and would grow poorly if at all and not produce spores
aerobically. Listeria monocytogenes and Lactobacillus species are gram positive bacilli; however, neither of
these produce spores.
The colonies seen in the upper frame, grown after 48 hours incubation aerobically at 35°C, and the
accompanying gram stain in the lower frame are uncommonly associated with human disease, but have been
associated with septicemia, bronchopneumonia, osteomyelitis and other infections, particularly in intravenous
drug users. The most likely identification is:
