“Pediculosis is a disease caused by the insect Pediculus humanus capitis that mainly occurs in childhood. A comparative study was carried out evaluating groups of schoolchildren with (group A) and without pediculosis (group B) to analyse the characteristics of the scalp microbiota. Samples were collected by swab using Stuart transport medium and incubate in Sabouraud dextrose agar with tetracycline to analyse the fungal microbiota and in blood agar to assess the bacterial microbiota. The isolates identity was confirmed by sequencing of the 16S and 18S regions of the ribosomal DNA gene for bacteria and fungi, respectively. The analysis of the 186 isolates led to the identification of 35 bacteria and 40 fungi in group A and 47 bacteria and 64 fungi in group B. The results indicate differences in bacterial and fungal species in the groups analysed. In the observed bacterial microbiota, Staphylococcus capitis occurred more frequently than Staphylococcus epidermidis in group A vs B. Among fungal isolates, Debaryomyces sp. was more frequent in group B vs A. Our findings showed scalp microbiota alterations in children with pediculosis, meriting future studies to analyse the relationship between these agents and their impact on human health.”

National Pediculosis Association Mission Statement

The NPA is a 501(c)(3) non-profit organization dedicated since 1983 to protecting children, their families and their environment from the misuse and abuse of prescription and over-the-counter pesticide treatments for lice and scabies.

Pediculosis (the medical term for an infestation of lice) provides a public health opportunity to teach important lessons about communicable disease preparedness, responsible personal behaviors, environmental health, and the importance of learning about pharmaceutical remedies before using them on our children and ourselves.

NPA is committed to setting the highest possible public health standards for children as they relate to the communicability and treatment of head lice. NPA has been the leader in raising pediculosis as a public health priority and a pioneer in public health education and research on pediculosis.

About LiceMeister® Comb

The NPA developed the LiceMeister® comb in 1997 to accomplish its mission by providing a higher standard for lice combing tools and a safe, cost-effective treatment alternative to pesticides. All proceeds from sales of the LiceMeister comb allow the NPA to be self-sustaining and independent from product manufacturers while accomplishing its mission of protecting children from the misuse and abuse of pesticide treatments for lice.

Since 1997, the LiceMeister comb has been the preferred choice of many health professionals and the gold standard in combing tools for lice and nits (lice eggs). It is an FDA cleared medical device (510K) for the purposes of routine screening, early detection and removal of lice and nits, and it is the only comb to carry the name of the National Pediculosis Association.
