Edited by Alfonso J. Rodriguez-Morales, ISBN 978-953-51-0274-8, 576 pages, Publisher: InTech, Chapters published March 16, 2012 under CC BY 3.0 licenseDOI: 10.5772/1335 Edited Volume Tropical Medicine has emerged and remained as an important discipline for the study of diseases endemic in the tropic, particularly those of infectious etiology. Emergence and reemergence of many tropical pathologies have recently aroused the interest of many fields of the study of tropical medicine, even including new infectious agents. Then evidence-based information in the field and regular updates are necessary. Current Topics in Tropical Medicine presents an updated information on multiple diseases and conditions of interest in the field.

University of Florida veterinarians identified the parasite, called Leishmania siamensis, in the summer of 2011. UF veterinarian Sarah Reuss, VMD, and colleagues have identified a rare, potentially fatal species of parasite in a Florida horse.

PLOS 05/09/13 Lungworm Infections in German Dairy Cattle Herds — Seroprevalence and GIS-Supported Risk Factor Analysis In November 2008, a total of 19,910 bulk tank milk (BTM) samples were obtained from dairy farms from all over Germany, corresponding to about 20% of all German dairy herds, and analysed for antibodies against the bovine lungworm Dictyocaulus viviparus by use of the recombinant MSP-ELISA. A total number of 3,397 (17.1%; n = 19,910) BTM samples tested seropositive. The prevalences in individual German federal states varied between 0.0% and 31.2% positive herds. INTECH - AVRIL 2012 - Zoonosis. Au sommaire: Insights into Leptospirosis, a Neglected Disease Edited by Jacob Lorenzo-Morales, ISBN 978-953-51-0479-7, 448 pages, Publisher: InTech, Chapters published April 04, 2012 under CC BY 3.0 licenseDOI: 10.5772/2125 Edited Volume Zoonotic diseases are mainly caused by bacterial, viral or parasitic agents although "unconventional agents" such as prions could also be involved in causing zoonotic diseases. Many of the zoonotic diseases are a public health concern but also affect the production of food of animal origin thus they could cause problems in international trade of animal-origin goods. A major factor contributing to the emergence of new zoonotic pathogens in human populations is increased contact between humans and animals. This book provides an insight on zoonosis and both authors and the editor hope that the work compiled in it would help to raise awareness and interest in this field.

PLOS 09/09/15 Mapping of Bancroftian Filariasis in Cameroon: Prospects for Elimination Abstract Background Lymphatic filariasis (LF) is one of the most debilitating neglected tropical diseases (NTDs). It still presents as an important public health problem in many countries in the tropics. In Cameroon, where many NTDs are endemic, only scant data describing the situation regarding LF epidemiology was available. Journal of Venomous Animals and Toxins including Tropical Diseases 2014, 20:5 Evaluation of canine and feline leishmaniasis by the association of blood culture, immunofluorescent antibody test and polymerase chain reaction Blood culture, IFAT and PCR for Leishmania spp Of the analyzed canine blood cultures from Botucatu, three (6%) were positive and forty-seven (94%) negative. But among cats, two samples (4%) were positive and 48 (96%) negative. Both the IFAT and PCR for Leishmania spp. found that 100% of both the dog and cat samples were negative. The blood cultures of animals from Campo Grande presented 29 (58%) dog samples positive and 21 (42%) negative.

PLOS 11/07/13 Strongyloides stercoralis: Global Distribution and Risk Factors Abstract Background The soil-transmitted threadworm, Strongyloides stercoralis, is one of the most neglected among the so-called neglected tropical diseases (NTDs). We reviewed studies of the last 20 years on S. stercoralis's global prevalence in general populations and risk groups. Methods/Principal Findings A literature search was performed in PubMed for articles published between January 1989 and October 2011. PLOS 01/12/16 Using Community-Level Prevalence of Loa loa Infection to Predict the Proportion of Highly-Infected Individuals: Statistical Modelling to Support Lymphatic Filariasis and Onchocerciasis Elimination Programs Abstract Lymphatic Filariasis and Onchocerciasis (river blindness) constitute pressing public health issues in tropical regions. Global elimination programs, involving mass drug administration (MDA), have been launched by the World Health Organisation. Although the drugs used are generally well tolerated, individuals who are highly co-infected with Loa loa are at risk of experiencing serious adverse events.

Korean J Parasitol. 2013 Oct;51(5):545-549. An Autochthonous Case of Canine Visceral Leishmaniasis in Korea Leishmaniasis is a group of infectious diseases that affect people and domestic and wild animals worldwide and are caused by species of the genus Leishmania, transmitted by sandflies. About 30 species of Leishmania infect humans as well as domestic and wild animals in 88 countries. Dogs act as a reservoir host of the disease for human infections; they are considered to be the reservoir for Leishmania infantum infection in areas including Portugal, the Mediterranean basin, Central and South America, the Middle East, and China [1]. Human leishmaniasis is classified into cutaneous (CL), mucocutaneous (MCL), and visceral leishmaniasis (VL) according to their clinical manifestations, but dogs usually have both visceral and cutaneous involvement [1]. As the first detailed human case report in the Republic of Korea (=Korea), Heu [2] described 3 cases of Kala-azar (=visceral leishmaniasis) among returnees from northern China.

BMC Research Notes 2013, 6:200 Strongyloides stercoralis is a cause of abdominal pain, diarrhea and urticaria in rural Cambodia Strongyloidiasis, an infection of an intestinal parasitic nematode, affects about 30–100 million people worldwide [1,2]. It is endemic in areas where sanitary conditions are poor and where the climate is warm and humid [3]. The clinical manifestations of strongyloidiasis vary greatly according to infection intensity and the immune-status of the patient. It is thought that more than 50% of all infections remain asymptomatic [4-6]. In Cambodia, a recent study showed that 24.4% and 49.3% of schoolchildren were infected with strongyloidiasis and hookworm, respectively [7]. Here, we report on the clinical manifestations of 21 strongyloidiasis patients from the rural province of Preah Vihear in northern Cambodia, with high numbers of S. stercoralis larvae in their feces.

OMS - 2009 - The Global Burden of Leptospirosis The Global Burden of Leptospirosis What do we know? Leptospirosis is a zoonotic disease caused by bacteria of the genus Leptospira. It is most commonly spread via water contaminated with urine from infected animals, but contaminated food or soil can also act as vehicles for the disease. The main animal reservoirs are rodents, livestock and dogs. PLOS 19/12/16 The Impact of Lymphatic Filariasis Mass Drug Administration Scaling Down on Soil-Transmitted Helminth Control in School-Age Children. Present Situation and Expected Impact from 2016 to 2020. Abstract Lymphatic filariasis (LF) and soil-transmitted-helminths (STH) are co-endemic in 58 countries which are mostly in Africa and Asia. Worldwide, 486 million school-age children are considered at risk of both diseases. In 2000, the World Health Organization (WHO) established the global programme to eliminate LF by 2020. Since then, the LF elimination programme has distributed ivermectin or diethylcarbamazine citrate (DEC) in combination with albendazole, thereby also treating STH. Consequently, many school-age children have been treated for STH through the LF programme.

Saúde Pública vol.29 no.12 Rio de Janeiro Dec. 2013 Cost-effectiveness of prevention strategies for American tegumentary leishmaniasis in Argentina Services on Demand Article Indicators Related links PLOS 09/05/13 A Public Health Response against Strongyloides stercoralis: Time to Look at Soil-Transmitted Helminthiasis in Full Strongyloides stercoralis infections have a worldwide distribution with a global burden in terms of prevalence and morbidity that is largely ignored. A public health response against soil-transmitted helminth (STH) infections should broaden the strategy to include S. stercoralis and overcome the epidemiological, diagnostic, and therapeutic challenges that this parasite poses in comparison to Ascaris lumbricoides, Trichuris trichiura, and hookworms. The relatively poor sensitivity of single stool evaluations, which is further lowered when quantitative techniques aimed at detecting eggs are used, also complicates morbidity evaluations and adequate drug efficacy measurements, since S. stercoralis is eliminated in stools in a larval stage. Specific stool techniques for the detection of larvae of S. stercoralis, like Baermann's and Koga's agar plate, despite superiority over direct techniques are still suboptimal. Figures
