    Department of Vector Ecology and Environment, Institute of Tropical Medicine (Nekken), Nagasaki University.
    Aedes albopictus is an important vector of dengue fever and tends to ambush blood host in a single place. Thus, host contact frequency may affect the bite rate and risk of disease outbreak, although no studies have examined these parameters. The present study used a simple model to clarify the fundamental relationship between host availability, bite rate, and risk of dengue outbreaks in non-endemic areas. Read More

    Humoral protection against mosquito bite-transmitted Plasmodium falciparum infection in humanized mice.
    NPJ Vaccines 2017 9;2:27. Epub 2017 Oct 9.
    Center for Infectious Disease Research, Seattle, WA USA.
    A malaria vaccine that prevents infection will be an important new tool in continued efforts of malaria elimination, and such vaccines are under intense development for the major human malaria parasite Plasmodium falciparum (Pf). Antibodies elicited by vaccines can block the initial phases of parasite infection when sporozoites are deposited into the skin by mosquito bite and then target the liver for further development. However, there are currently no standardized in vivo preclinical models that can measure the inhibitory activity of antibody specificities against Pf sporozoite infection via mosquito bite.

    Variable manifestations, diverse seroreactivity and post-treatment persistence in non-human primates exposed to Borrelia burgdorferi by tick feeding.
    PLoS One 2017 13;12(12):e0189071. Epub 2017 Dec 13.
    Center for Comparative Medicine, Schools of Medicine and Veterinary Medicine, University of California Davis, Davis, CA, United States of America.
    The efficacy and accepted regimen of antibiotic treatment for Lyme disease has been a point of significant contention among physicians and patients. While experimental studies in animals have offered evidence of post-treatment persistence of Borrelia burgdorferi, variations in methodology, detection methods and limitations of the models have led to some uncertainty with respect to translation of these results to human infection. With all stages of clinical Lyme disease having previously been described in nonhuman primates, this animal model was selected in order to most closely mimic human infection and response to treatment.

    Infection via mosquito bite alters Zika virus tissue tropism and replication kinetics in rhesus macaques.
    Nat Commun 2017 Dec 13;8(1):2096. Epub 2017 Dec 13.
    Department of Pathobiological Sciences, University of Wisconsin-Madison School of Veterinary Medicine, 1656 Linden Dr., Madison, WI, 53706, USA.
    Mouse and nonhuman primate models now serve as useful platforms to study Zika virus (ZIKV) pathogenesis, candidate therapies, and vaccines, but they rely on needle inoculation of virus: the effects of mosquito-borne infection on disease outcome have not been explored in these models. Here we show that infection via mosquito bite delays ZIKV replication to peak viral loads in rhesus macaques. Importantly, in mosquito-infected animals ZIKV tissue distribution was limited to hemolymphatic tissues, female reproductive tract tissues, kidney, and liver, potentially emulating key features of human ZIKV infections, most of which are characterized by mild or asymptomatic disease.

Immunization with Plasmodium falciparum NF54 parasites under chemoprophylaxis (chemoprophylaxis and sporozoite (CPS)-immunization) induces the most efficient long-lasting protection against a homologous parasite. However, parasite genetic diversity is a major hurdle for protection against heterologous strains. Read More

    Chikungunya virus (CHIKV) transmission occurs through the bite of an infected Aedes mosquito which injects virus-containing saliva into the skin of the human host during blood feeding. In the present study, we have determined the effect of Aedes aegypti saliva on CHIKV replication in human skin fibroblasts, a major cell type for viral entry, which mimics the events that occur during natural transmission. A significant increase in the expression of viral transcripts and infectious viral particles was observed in fibroblasts infected with CHIKV in the presence of saliva, as compared with those infected with virus alone.

    Yersinia pestis is a gram-negative, zoonotic, bacterial pathogen, and the causative agent of plague. The bubonic form of plague occurs subsequent to deposition of bacteria in the skin by the bite of an infected flea. Neutrophils are recruited to the site of infection within the first few hours and interactions between neutrophils and Y. Read More

    Laceration Management.
    J Emerg Med 2017 Sep 25;53(3):369-382. Epub 2017 Aug 25.
    East Orange General Hospital, East Orange, New Jersey.
    Background: Traumatic lacerations to the skin represent a fairly common reason for seeking emergency department care. Although the incidence of lacerations has decreased over the past decades, traumatic cutaneous lacerations remain a common reason for patients to seek emergency department care.

    Objective: Innovations in laceration management have the potential to improve patient experience with this common presentation. Read More

    O'nyong-nyong fever: a neglected mosquito-borne viral disease.

    O'nyong nyong virus (ONNV), a mosquito-borne Alphavirus, is primarily transmitted through the bite of Anopheles funestus and Anopheles gambiae mosquitoes, which are also malaria parasite vectors in Africa. The virus, first isolated in Uganda in 1959, is endemic in sub-Saharan Africa and has caused several major outbreaks both in West and East Africa. ONNV fever, characterized by severe arthralgia, is similar to chikungunya fever, with the exception of cervical lymphadenitis, which is peculiar to the former. Read More
