Kingella kingae seen more frequently in Jewish children than Bedouins
Further data are needed to help understand the differences in prevalence of Kingella kingae infection between Jewish children and Bedouin children, according to recently published study results.
Pablo Yagupsky, MD, of the Ben-Gurion University of the Negev, Beer-Sheva, Israel, and colleagues published data on 1,277 Jewish and 1,664 Bedouin children, who were enrolled over a 2-year period that began in November 2009. Eighty-two children were colonized with K. kingae; 52 of whom were Jewish.
The researchers said although the “carriage rate of K. kingae among Jewish and Bedouin children living in southern Israel paralleled the age-related incidence of invasive infections,” living in a shanty town actually seemed protective against infection in the Bedouin children.
Those attending day care and aged 6 to 29 months were at risk for colonization with K. kingae. The researchers attributed these risk factors to fading immunity after 6 months and increased socialization that predisposed the children to transmission.
“Because the medical literature on invasive K. kingae disease is mostly limited to case series from Western countries, scarcity of reports from developing world regions suggests that the organism mainly affects affluent populations,” the researchers wrote.
However, they added, it is possible that this diagnosis is missed in developing countries because the specific lab tests in these areas are unavailable, which limits accurate comparative data.
