Transmission ofBordetella holmesiiduring Pertussis Outbreak, Japan

Abstract: We describe the epidemiology of a pertussis outbreak in Japan in 2010–2011 and Bordetella holmesii transmission. Six patients were infected; 4 patients were students and a teacher at the same junior high school. Epidemiologic links were found between 5 patients. B. holmesii may have been transmitted from person to person.

“…Another possible reason for the highest positivity rates in preteens and teenagers could be the presence of Bordetella holmesii infection or B. pertussis/B. holmesii coinfection (9)(10)(11). This possibility could not be assessed in our study, as the IS481 target does not differentiate between the two species, and B. holmesiispecific testing was not performed.…”

“…During an outbreak in Japan, Kamiya [13] observed epidemiological links between patients, suggesting that B. holmesii might have been transmitted from person to person. However, as previously stated, no other diagnostic tests were undertaken to check that B. holmesii was really the source of the whooping cough symptoms.…”

“…This poses a potential problem, because the diagnosis of B. pertussis infection is based on the PCR detection of IS481 sequences. The development of specific PCR diagnosis for B. holmesii infection, targeting the recA gene [7][8][9], or the transposase IS1001bho [10], the amplification of specific target as bhoE [11] or the sequencing of 16sRNA or OmpA [12] has made it possible for a number of retrospective studies to demonstrate an increase in the number of reported cases of respiratory infections due to B. holmesii over the last few years [10,11,[13][14][15][16][17][18][19][20][21]. We wondered whether this increase in detection reflected a real increase in the number of infections or was simply a consequence of the increasing use of RT-PCR targeting IS481 for the diagnosis of B. pertussis since 2005.…”

“…In Japan, children receive 4 doses of the DTaP vaccine, with 3 primary doses and a single booster dose at ages 3, 4, 5, and 18 to 23 months. Thus, a decreased protective effect of the vaccine may contribute to the increasing frequency of pertussis in the last decade on college campuses and in high schools and offices in Japan (6)(7)(8)(9)(10). Pertussis prevention among young adults is important because unrecognized adult pertussis is the major source of pertussis in young infants, in whom the disease can be severe and fatal (2).…”
