RT Journal Article SR Electronic T1 Dipylidium caninum in a 4-month old male JF American Society for Clinical Laboratory Science JO Clin Lab Sci FD American Society of Chemistry and Laboratory Science SP 212 OP 214 DO 10.29074/ascls.24.4.212 VO 24 IS 4 A1 Taylor, Tabitha A1 Zitzmann, Michele YR 2011 UL http://hwmaint.clsjournal.ascls.org/content/24/4/212.abstract AB Dipylidium caninum, known as the double-pored dog tapeworm, is a parasite that commonly infects dogs and cats worldwide. Humans may be an accidental host if the infective stage, the cysticercoid larva, is ingested.1,2 Although rare, it is more commonly seen in infants and children.2-5 This case study involves an infant misdiagnosed with pinworm infection twice before a laboratory evaluation was able to confirm Dipylidium caninum. Accurate diagnosis is important, as treatment for pinworm infection will not eliminate Dipylidium caninum.
