The report in this issue by Dr. Hall of a case of ankylostomiasis in
a sailor, dying from this disease in Baltimore, shows the importance of careful
examination of the feces in obscure cases of anemia associated with intestinal
disturbances. Ankylostomiasis, or uncinariosis, is a comparatively unknown
disease in the United States. In some of the new possessions, however, it
is probably quite as frequent as in other countries, such as Egypt. According
to Lieutenant B. K. Ashford1 ankylostomiasis
is the most general and most harmful disease—a veritable curse—in
Porto Rico. Allyn and Beard2, reporting
a case in an Italian in Philadelphia, review some of the cases observed in
this country, and they express the belief that it is more frequent than the
few scattered reports seem to indicate3.
The diagnosis is established by finding the ankylostoma eggs in the feces.
The eggs are described by Manson4 as beautifully
clear and transparent, 55 to 65 by 32 to 43 mikrons in size, oval, with delicate
transparent shells, through which two or four light gray yolk segments can
be seen distinctly. The ova are to be sought for soon after the feces are
