Conclusions and Clinical Relevance-In this setting, monthly
topical administration of 10% imidacloprid-1% moxidectin reduced
flea infestation, compared with infestation in untreated cats,
and thus prevented flea transmission of B henselae to treated
cats. Regular monthly use of this flea control product in cats
may lessen the likelihood of humans acquiring B henselae
infection.
