An otherwise healthy 10-year-old girl presented to the primary care clinic with a 10-day history of multiple itchy papules on the soles of her feet and on her toes. The lesions had black dots in the center and were painful. Two weeks earlier, the family had traveled to rural Brazil. During that time, the patient had played in a pigsty without wearing shoes. Sand fleas were removed from multiple lesions. What is the most likely diagnosis? Coxsackievirus infection Furuncular myiasis Foreign body granulomas Tungiasis Scabies infestation Correct! The correct answer is tungiasis. Tungiasis is a skin infestation caused by the sand flea Tunga penetrans, an ectoparasite that is found throughout tropical and subtropical parts of the world. Treatment included flea removal and local wound care. Die Myiasis (nach griechisch μυῖα myia = „Fliege“) oder auch Fliegenmadenkrankheit ist der Befall von Lebewesen mit den Larven (Maden) von Fliegen, welche von dem Gewebe, den Körperflüssigkeiten oder dem Darminhalt des Wirtes leben. Sie ist bei Menschen in Mittel- und Südamerika sowie in Regionen mit tropischen oder subtropischem Klima verbreitet. In der Tiermedizin kommt ein Fliegenmadenbefall auch in Europa häufiger vor. Betroffen sind vor allem stark geschwächte oder anderweitig erkrankte Tiere, die nicht mehr in der Lage sind, sich selbst zu putzen.

  • Insect Biodiversity: Science and Society, II R.G
    In: Insect Biodiversity: Science and Society, II R.G. Foottit & P.H. Adler, editors) John Wiley & Sons 2018 Chapter 17 Biodiversity of Ectoparasites: Lice (Phthiraptera) and Fleas (Siphonaptera) Terry D. Galloway Department of Entomology, University of Manitoba, Winnipeg, Manitoba, Canada https://doi.org/10.1002/9781118945582.ch17 Summary This chapter addresses the two insect orders in which all known species are ectoparasites. The sucking and chewing lice (Phthiraptera) are hemimetabolous insects that spend their entire lives on the bodies of their hosts. Fleas (Siphonaptera), on the other hand, are holometabolous. The diversity of these ectoparasites is limited by the diversity of the birds and mammals available as hosts. Determining the community diversity of lice and fleas is essential to understanding ecological structure and interactions, yet offers a number of challenges to the ectoparasitologist. The chapter explores medical and veterinary importance of lice and fleas. They are more likely to be considered detrimental parasites, perhaps even a threat to conservation efforts by their very presence or by the disease agents they transmit. Perez-Osorio emphasized the importance of a more objective approach to conservation strategies by abandoning overemphasis on charismatic fauna and setting priorities in ecological management of wider biodiversity issues. When most people see a bird or mammal, they don’t look beneath the feathers or hair of that animal to see what is hidden. They see the animal at its face value, and seldom appreciate the diversity of life before them. The animal is typically a mobile menagerie, infested by external parasites and their body laden with internal parasites and pathogens.

Received 23 November, 2016; Accepted 4 July, 2017 Tungiasis exists worldwide with varying degrees of incidence and prevalence. The aim of this paper is to review the existing literature on Tungiasis which has been shown to be a public health concern for resource-poor rural communities in developing countries such as Nigeria, Kenya, Cameroon, Trinidad, Tobago and Brazil, where its prevalence has been known to reach 50%. Reviewed literature showed that poor hygienic conditions, increased poverty levels, prolonged dry season and fear of stigmatization are among the most important risk factors, severely influencing the persistence of the tungiasis. The presence of the jigger in the skin causes itching sensation, and in severe cases causes loss of nails, formation of ulcers, inflammation, suppuration, chronic lymphedema, sepsis and even death. Jigger infestation affects the education of children as they might be unable to walk to school, write properly, or participate in regular learning activities. Tungiasis is likely to increase and cause livelihood of communities in developing countries. Thus, new prevention and control approaches should be designed through multi-interdisciplinary team to mitigate the persistence of the disease, particularly in vulnerable communities.

    Risk Factors for Tungiasis in Nigeria: Identification of Targets for Effective Intervention Uade Samuel Ugbomoiko1, Liana Ariza2, Ifeanyi Emmanuel Ofoezie3,Jo¨ rg Heukelbach2,4* 1 Department of Zoology, University of Ilorin, Ilorin, Nigeria, 2 Department of Community Health, School of Medicine, Federal University of Ceara´, Fortaleza, Brazil, 3 Department of Zoology, University of Nigeria, Nsukka, Nigeria, 4 School of Public Health, Tropical Medicine and Rehabilitation Sciences, James Cook University, Townsville, Australia Abstract Background: The parasitic skin disease tungiasis (caused by the flea Tunga penetrans) affects resource-poor communities in Latin America, the Caribbean and sub-Saharan Africa. Prevalences in endemic areas are high, and severe pathology occurs commonly. However, risk factors for infestation have never been assessed in Africa. Methods and Findings: A cross-sectional study was conducted in Erekiti, a rural community in Lagos State (Nigeria), where tungiasis is endemic. Individuals were examined clinically for the presence of tungiasis, and a questionnaire was applied. Data from 643 individuals (86.6% of the target population) were analyzed; 252 (42.5%) were infested with T. penetrans.In the multivariate logistic regression analysis, presence of pigs on the compounds (adjusted odds ratio = 17.98; 95% confidence interval: 5.55–58.23), sand or clay floor inside houses (9.33; 5.06–17.19), and having the common resting place outside the house (7.14; 4.0–14.29) were the most important risk factors identified. The regular use of closed footwear (0.34; 0.18–0.62) and the use of insecticides indoors (0.2; 0.05–0.83) were protective against infestation.

Bailey Hortorium, Department of Plant Biology 412 Mann Library Building Cornell University Ithaca, New York 14853-4301 [email protected] ABSTRACT A revised summary of the organisms illustrated by the English naturalist Mark Catesby in his 1729-1747 Natural history of Carolina, Florida, and the Bahama Islands is presented based on the findings of the author and several of the participants who gave papers during the Catesby Tercentennial symposia (4–9 November 2012). This paper updates the findings published earlier by Reveal (2012a). In addition to a full account of the published images, the identity of the organisms illustrated by Catesby and preserved mainly as watercolors at the Royal Library, Windsor Castle, England, is also presented along with indices of scientific names with common names, scientific names arranged by common names, Catesby etching and watercolors arranged by scientific names, and an index to Catesby’s polynomial and common names with references to the published etchings. The purpose of this paper is to provide an up-to-date identification of the plants and animals illustrated by Mark Catesby (1729–1747) in his Natural History and depicted in the currently available original watercolors (Catesby 1996) preserved in the Royal Library at Windsor Castle outside London, England.

For Context Ectoparasitoses (infestations with parasites that live example, tungiasis usually affects usually less than 1% of the on or in the skin) can cause considerable morbidity. Whereas population in an endemic area, but in economically dis- pediculosis and scabies are ubiquitous, cutaneous larva advantaged communities prevalence in children can reach migrans and tungiasis (sand-flea disease) occur mainly in hot 76%.1 In some indigenous populations in the Amazon rain climates. The prevalence of ectoparasitoses in the general forest nearly all individuals have head lice. population is usually low, but can be high in vulnerable The occurrence of parasitic skin diseases is influenced by groups. Scientific knowledge on how to deal best with meteorological variables. In the semi-arid climate of North- parasitic skin diseases in different settings is scanty, and east Brazil, for instance, the incidence of the four major evidence-based measures for control are not available. For ectoparasitoses varies by season. In temperate climates, the head lice and scabies the situation is daunting, because incidence of scabies increases in the winter.2 resistance of Pediculus humanus capitis and Sarcoptes In developing countries, particularly in poor people, poly- scabiei to insecticides is spreading and unpredictable. parasitism is frequent. Even when common, parasitic skin diseases are easily overlooked.
