    Detection of bacterial pathogens including potential new species in human head lice from Mali.
    PLoS One 2017 20;12(9):e0184621. Epub 2017 Sep 20.
    Aix Marseille Univ, CNRS, IRD, INSERM, AP-HM, URMITE, IHU - Méditerranée Infection, Marseille, France.
    In poor African countries, where no medical and biological facilities are available, the identification of potential emerging pathogens of concern at an early stage is challenging. Head lice, Pediculus humanus capitis, have a short life, feed only on human blood and do not transmit pathogens to their progeny. They are, therefore, a perfect tool for the xenodiagnosis of current or recent human infection. Read More

    [A negleted bacteria with a case: Bartonella henselae].
    Mikrobiyol Bul 2017 Jul;51(3):286-292
    Bagcilar Training and Research Hospital, Department of Infectious Diseases and Clinical Microbiology, Istanbul, Turkey.
    Bartonella henselae the causative agent of cat scratch disease (CSD), is a gram-negative, coccobacillus, facultative intracellular bacterium CSD usually presents as a clinical form of benign local lymphadenopathy (LAP) but sometimes it may progress to severe life threatening complications. Despite the fact that CSD is known to be a common disease, which is one of the important causes of local LAPs in the world, there are few publications in our country. For the diagnosis, the clinician should suspect for CSD and has to ask to the patient whether there is a story of cat scratch or not. Read More
