4) Seventeen patients in ten hospitals had cutaneous infections caused by Rhizopus. In all
seventeen patients, Elastoplast bandages were placed over sterile gauze pads to cover
wounds. Fourteen of the patients had surgical wounds, two had venous line insertion sites,
and one had a bite wound. Lesions present when the bandages were removed ranged from
vesiculopustular eruptions to ulcerations and skin necrosis requiring debridement. Fungi are
more likely than bacteria to contaminate bandages because they A) are aerobic.
B) can tolerate low-moisture conditions. C) prefer a neutral environment (pH 7). D) have a
fermentative metabolism.
E) cannot tolerate high osmotic pressure. Answer: B

A) Lichens are a mutualistic relationship between a fungus and a protozoan. B) Lichens
represent a mutualistic relationship between a fungus and an alga. C) Lichens are often the
first life form to colonize rock or soil.
D) The algal partner produces carbohydrates that are absorbed by the fungal partner.
E) The fungal partner provides a means of attachment and protects the algal partner from
desiccation. Answer: A
