prehistoric juvenile rheumatoid arthritis in a precontact louisiana native population reconsidered.descriptions of skeletal pathological conditions evident in the prehistoric tchefuncte adolescent 16st1-14883b are clarified. the basis is reaffirmed for assigning to the described pathological conditions a diagnostic perspective of juvenile rheumatoid arthritis or juvenile lyme disease--a disease that mimics juvenile rheumatoid arthritis in its arthritic presentation--rather than of assigning them as representative of juvenile onset ankylosing spondylitis or other juvenile spondyloarthropathies ...19989637186
detection of human bacterial pathogens in ticks collected from louisiana black bears (ursus americanus luteolus).there are 4 major human-biting tick species in the northeastern united states, which include: amblyomma americanum, amblyomma maculatum, dermacentor variabilis, and ixodes scapularis. the black bear is a large mammal that has been shown to be parasitized by all the aforementioned ticks. we investigated the bacterial infections in ticks collected from louisiana black bears (ursus americanus subspecies luteolus). eighty-six ticks were collected from 17 black bears in louisiana from june 2010 to ma ...201323415850
treponematosis and lyme borreliosis connections: explanation for tchefuncte disease syndromes?a convergence of evidence from macroscopic, radiographic and histologic examination indicates that treponemal infection was present in the 16st1 tchefuncte indian burial population, dated 500 b.c. to 300 a.d. pattern and nature of lesions suggests that chronic infection induced by variants of the spirochete treponema pallidum, causing endemic syphilis and/or yaws, resulted in third-stage osseous response. it is suggested that tchefuncte indians acquired partial immunity to treponemal infection b ...19948048468
hitting the target: lyme or stari?erythema migrans (em) is a characteristic rash most commonly associated with lyme disease (ld) in the northeastern and north central united states. em rash found in the southeastern united states is usually classified as southern tick-associated rash illness (stari). here we describe an em rash in a 3-year-old female from central louisiana, whose laboratory and clinical findings were suspicious for ld. this case report highlights the importance of distinguishing stari from ld, as ld left untreat ...201323734537
endemic tickborne infectious diseases in louisiana and the gulf south.most emerging infectious diseases today, such as west nile virus and sudden acute respiratory distress syndrome (sars), arise from zoonotic reservoirs and many are transmitted by arthropod vectors. ticks are among the most competent and versatile arthropod vectors of infectious diseases because ticks of all ages and both sexes remain infectious for generations without having to reacquire infections from reservoir hosts. today, ticks transmit the most common arthropod-borne infectious disease in ...200920108827
comparison of tick feeding success and vector competence for borrelia burgdorferi among immature ixodes scapularis (ixodida: ixodidae) of both southern and northern clades.northern and southern ixodes scapularis say populations differ greatly in density, host utilization, and especially questing behavior of the immatures. haplotypes of i. scapularis in north america can be divided into two major clades-the all american clade (haplotypes a through j) and the southern clade (m through o). this genetic variation may affect feeding success and vector competence. this study compared feeding success of larval i. scapularis measured by time-to-drop-off and subsequent tra ...201526336283
detection of lyme borrelia in questing ixodes scapularis (acari: ixodidae) and small mammals in louisiana.lyme borreliosis is caused by spirochetes from the borrelia burgdorferi sensu lato species complex. in the united states, b. burgdorferi sensu stricto (s.s.; johnson, schmid, hyde, steigerwalt, and brenner) is the most common cause of human lyme borreliosis. with >25,000 cases reported annually, it is the most common vector-borne disease in the united states. although approximately 90% of cases are contained to the northeastern and great lake states, areas in canada and some southern states are ...201424605479
