What Do Lice Look Like & How To Do Away With Them Fast
The Ultimate Guide That Puts Kids First When parents discover their child has lice their typical reaction is dread. The dread comes from not really knowing what to do while feeling pressure to address the situation immediately. It’s easy to understand why. There is an overwhelming amount of information about lice on the web with all sides weighing in: the Centers for Disease Control and Prevention (CDC), the American Academy of Pediatrics (AAP), the National Pediculosis Association (NPA), the National Association of School Nurses, researchers, public health departments, school districts, universities, hospitals, allopathic health practitioners, holistic health practitioners, mommy blogs, mainstream news media, alternative news media, professional lice treatment services …

Head Lice: Everyone Wins When Everyone Combs!
For Immediate Release. August 14, 2019. National Pediculosis Association Urges Parents to Be Proactive Newton, MA — August is back-to-school for many communities across the nation and time to prepare the kids for returning to the classroom. The National Pediculosis Association (NPA) encourages parents to screen their children’s hair for pediculosis so these students can join their friends free of lice and their nits (lice eggs). The message for parents is to be diligent about pediculosis – a communicable parasitic disease that is well established among the childhood population. The NPA is a nonprofit organization dedicated to setting the highest possible public health standards to protect children from both head lice and the risky pesticide-based lice …
CombFirst! Before Camp, Advises the National Pediculosis Association
"As children and teens dive into the summer camp season, the National Pediculosis Association (NPA) today encouraged parents, counselors, camp nurses and administrators to prevent head lice from interfering with even a minute of fun! 'Camps that promote parental preparedness via screening for lice before camp are one giant step ahead,' said Deborah Altschuler, President of the NPA, a nonprofit organization advocating for children to arrive at camp lice and nit free. 'There are camp directors spending thousands of dollars checking children for pediculosis upon arrival without teaching parents how to comb their children for lice and nits at home. Parents can and should be first to detect infestations before sending children to camp. Those who know about screening for head lice with a lice …

Genetic diversity of human head lice and molecular detection of associated bacterial pathogens in Democratic Republic of Congo
Background Head louse, Pediculus humanus capitis, is an obligatory blood-sucking ectoparasite, distributed worldwide. Phylogenetically, it occurs in five divergent mitochondrial clades (A–E); each exhibiting a particular geographical distribution. Recent studies suggest that, as in the case of body louse, head louse could be a disease vector. We aimed to study the genetic diversity of head lice collected in the Democratic Republic of the Congo (DR Congo) and to screen for louse-borne pathogens in these lice. Methods A total of 181 head lice were collected from 27 individuals at the Monkole Hospital Center located in Kinshasa. All head lice were genotyped and screened for the presence of louse-borne bacteria using molecular methods. We searched for Bartonella …
Scalp microbiota alterations in children with pediculosis.
“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 …

Head Lice Recognize and Prefer Head Odor Over Foot and Forearms Odors
“Human head lice, Pediculus humanus capitis De Geer (Phthiraptera: Pediculidae), are hematophagous parasites that infest human heads. They are extreme host specialists suggesting a strict selection behavior towards the human head by the parasites. Despite the public health relevance of P. humanus capitis, the role of chemical clues to select the human head is not well known. In the present study, we attempted to find out whether head lice recognize and select the odor of the head over the odor of other parts of the human body. Our results using a two-choice olfactometer demonstrated that head lice were highly attracted by the volatile compounds of the human odor air, but they did not show preference for the volatiles of head compared to the volatiles of other parts of the body (forearm or …

Report of the human body louse (Pediculus humanus) from clothes sold in a market in central Italy
“Pediculus humanus, the human body louse, is widespread where overcrowding and lack of hygiene are present, in areas of the world affected by poverty, war, famine and presence of refugees. It has recently been considered re-emerging among homeless populations in developed countries. In Italy, it was last reported in 1945. Pediculus humanus is a vector of highly relevant human pathogens.” De Liberato C1, Magliano A2, Romiti F2, Menegon M3, Mancini F3, Ciervo A3, Di Luca M3, Toma L3.

The Sensory Machinery of the Head Louse Pediculus humanus capitis: From the Antennae to the Brain
“Insect antennae are sophisticated sensory organs, usually covered with sensory structures responsible for the detection of relevant signals of different modalities coming from the environment. Despite the relevance of the head louse Pediculus humanus capitis as a human parasite, the role of its antennal sensory system in the highly dependent relation established with their hosts has been barely studied. In this work, we present a functional description of the antennae of these hematophagous insects by applying different approaches, including scanning electron microscopy (SEM), anterograde antennal fluorescent backfills, and behavioral experiments with intact or differentially antennectomized lice. Results constitute a first approach to identify and describe the head louse antennal …
