Fish die-offs are important signals in tropical marine ecosystems. In 2010, a mass mortality of pufferfish in Hawaii (USA) was dominated by Arothron hispidus showing aberrant neurological behaviors. Using pathology, toxinology, and field surveys, we implicated a series of novel, polar, marine toxins as a likely cause of this mass mortality. Our findings are striking in that (1) a marine toxin was associated with a kill of a fish species that is itself toxic; (2) we provide a plausible mechanism to explain clinical signs of affected fish; and (3) this epizootic likely depleted puffer populations...

We describe two serious Trametes polyzona pulmonary infections, which occurred in Réunion Island, in critically ill patients. The identification was performed using sequencing of the internal transcribed spacer region of ribosomal DNA and D1/D2 region of 28S rDNA. In one case, the significance of T. polyzona in the pathological process was certain, proven by histopathological evidence of fungal lung infection. T. polyzona, an emerging filamentous basidiomycete, prevalent in tropical areas, has not been described so far in human infections...

The demand for expertise in pathology for the diagnosis of infectious diseases (ID) is continually growing, due to an increase in ID in immunocompromised patients and in the (re)-emergence of common and uncommon diseases, including tropical infections and infections with newly identified microbes. The microbiology laboratory plays a crucial role in diagnosing infections, identifying the responsible infectious agents and establishing sensitivity of pathogens to drug therapy. Pathology, however, is the only way to correlate the presence of an infectious agent with the reaction it evokes at cell and tissue level...

Re-emergence of chikungunya virus, a mosquito-transmitted pathogen, is of serious public health concern. In the past 15 years, after decades of infrequent, sporadic outbreaks, the virus has caused major epidemic outbreaks in Africa, Asia, the Indian Ocean, and more recently the Caribbean and the Americas. Chikungunya virus is mainly transmitted by Aedes aegypti mosquitoes in tropical and subtropical regions, but the potential exists for further spread because of genetic adaptation of the virus to Aedes albopictus, a species that thrives in temperate regions...

Theileria are obligate eukaryotic intracellular parasites of cattle. The diseases they cause, Tropical theileriosis and East Coast Fever, cause huge economic loss in East African, Mediterranean and central and South-East Asian countries. These apicomplexan parasites are the only intracellular eukaryotic parasites known to transform their host cell and represent a unique model to study host-parasite interactions and mechanisms of cancer onset. Here, we review how Theileria parasites induce transformation of their leukocyte host cell and discuss similarities with tumorigenesis...

BACKGROUND: The vector-borne cutaneous leishmaniasis (CL) is endemic in several regions of Pakistan mainly affecting poor populations. Host genetic factors, particularly SLC11A1 (solute carrier transmembrane protein) within macrophages, play a crucial role in disease pathology and susceptibility. Association of SLC11A1 with cutaneous leishmaniasis, a neglected tropical disease, is not well established. Inconsistencies have been observed within different populations worldwide with respect to genetic susceptibility...

BACKGROUND: Pyomyositis is an acute bacterial infection of skeletal muscle that results in localized abscess formation. This infection was thought to be endemic to tropical countries, and is also known as "tropical pyomyositis". However, pyomyositis is increasingly recognized in temperate climates and is frequently associated with an immunosuppressive condition, such as human immunodeficiency virus, malignancy, and diabetes mellitus. It is also found in healthy and athletic people after strenuous or vigorous exercise or following localized and possibly unnoticed trauma...

Profound changes are occurring in the epidemiology of schistosomiasis, a neglected tropical disease caused by a chronic infection with parasitic helminths of the genus Schistosoma. Schistosomiasis currently affects 240 million people worldwide, mostly in sub-Saharan Africa. The advent and proliferation of mass drug administration (MDA) programmes using the drug praziquantel is resulting in substantial increases in the number of people, mainly children aged 6-14 years, being effectively treated, approaching the point where most people in endemic areas will receive one or more treatments during their lifetimes...

Despite its prominent position in today's medical research, popular culture and everyday life, cancer's history is relatively unwritten. Compared to the other great 'plagues' - cholera, tuberculosis or tropical fevers, to name but a scant handful - cancer has few dedicated pages in the general surveys, and its specialists have largely failed to convince the broader community of medical historians - or indeed historians of anything at all - that histories of the disease can tell us fundamental things about the science and practice of medicine, both past and present...

Interleukin 9 secreting TH9 cells have been proposed as the latest addition to the family of T helper cell subsets. While a growing body of evidence from animal models points to important roles for these cells in allergic inflammation of the lung, autoinflammation of the gastrointestinal tract, and tumor immunity, their role in skin immunity and skin immunopathology remains poorly defined. Interestingly, studies of T helper cells from healthy humans suggest that TH9 cells are predominantly skin-homing and skin-resident and that they are involved in protection against extracellular pathogens...

Buruli Ulcer is a neglected tropical disease leading to extensive disabilities and morbidity in West Africa. In this paper we sought to characterize various strains of Mycobacterium ulcerans (M.ulcerans) with different origins and laboratory passage records while refining a mouse model for Buruli ulcer. We described, compared and followed the kinetics of the histo-pathological outcome of infection of a collection of strains at various anatomical sites of infection in order to find a suitable model for further immunization studies...

Taxonomy and history: Hemileia vastatrix Berk. and Broome (Basidiomycota, Pucciniales) was described in 1869 in Eastern Africa and Ceylon as the agent of Coffee Leaf Rust and spread to all coffee cultivation areas worldwide. Major disease outbreaks in Asia, Africa and America caused and continue to cause severe yield losses, making this the most important disease of Arabica coffee, a cash crop for many tropical and sub-tropical countries. Life cycle and disease symptoms: Hemileia vastatrix is a hemicyclic fungus with the urediniosporic life cycle as its most important (if not only) source of inoculum...

OBJECTIVE: HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) can progress slowly or rapidly even though a set of symptoms such as spastic paraparesis with pathological reflexes and sweating loss of the lower extremities are commonly observed in patients. Although most of the patients are thought to be infected to HTLV-1 from their mothers by breast feeding, symptoms of HAM/TSP typically manifest in patients later in life (50-60years old in age) and also with a higher prevalence of women to men at a ratio of approximately 3:1...

Lichen sclerosus et atrophicus and limited systemic scleroderma (acrosclerosis) are inflammatory skin diseases that ultimately evolve into two distinct modes of atrophic scar formation, but which can easily be confused clinically. They are very rarely associated. The literature has reported cases in which lichen sclerosus was associated with various forms of scleroderma, but often with localized morphea. The characteristic histopathological picture of lichen sclerosus includes a thin epidermis, with orthohyperkeratosis and vascular degeneration in the basal layer, loss of elastic fibers, and band-like inflammatory infiltrate in the papillary dermis, while systemic sclerosis is characterized by excessive deposition of collagen in the dermis, accompanied by reduction in adnexal structures and their entrapment in collagen, and the presence of perivascular lymphocytic inflammatory infiltrate...

BACKGROUND: Malaria is an important tropical disease and has remained a serious health problem in many countries. One of the critical complications of malarial infection is renal injury, such as acute renal failure and chronic glomerulopathy. Few animal models of nephropathy related to malarial infection have been reported. Therefore, we developed and investigated a novel malarial nephropathy model in mice infected by murine malaria parasites. METHODS: NC mice and C57BL/6J mice were infected with Ttwo different murine malaria parasites, Plasmodium (P...

Pathology of HTLV-1 associated myelopathy/Tropical spastic paraparesis (HAM/TSP) is believed to be the result of "bystander damage" involving effector CD8 (+) T lymphocytes (CTLs) killing of virus infected cells. But the specific cellular events leading up to tissue injury are still unclear. Here, we developed the Microscopy Imaging of Cytotoxic T lymphocyte assay with Fluorescence emission (MI-CaFé), an optimized visualization analysis to explore the interactions between CTLs and virus infected or viral antigen presenting target cells...

Following up on the largest case-control study of malignant mesothelioma yet performed, investigators at the London School of Hygiene and Tropical Medicine assessed 1732 male and 670 female cases as of May 2013. Epidemiological findings of a subset of these were published previously, excluding patients who died or who refused to be interviewed. Pathology reports were collected for subjects, including those both eligible and ineligible for epidemiology study based on vital status. The current investigation examined 860 cases having pathology reports available...

Snakebite envenoming is a neglected public pathology, affecting especially rural communities or isolated areas of tropical and subtropical Latin American countries. The parenteral administration of antivenom is the mainstay and the only validated treatment of snake bite envenoming. Here, we assess the efficacy of polyspecific anti-Bothrops serum (α-BS) produced in the Instituto Nacional de Salud (INS, Peru) and at the Fundação Ezequiel Dias (FUNED, Brazil), to neutralize the main toxic activities induced by five medically-relevant venoms of: Bothrops atrox, B...

The digenetic trematodes, Fasciola gigantica and Gigantocotyle explanatum, belonging to the family Fasciolidae and Paramphistomidae respectively, have been often found to concurrently infect the liver of Indian water buffalo Bubalus bubalis, causing serious pathological damage to the vital organ, incurring huge economic losses. In the present study the soluble gene products of both F. gigantica and G. explanatum were analyzed by 2 dimensional polyacrylamide gel electrophoresis. The soluble proteomic profile revealed considerable similarity as well as differences in the size, distribution pattern, total number, the isoelectric point (pI) and molecular weight (Mr) of the resolved polypeptide spots...

Goats in the tropics are often reared under the traditional extensive and semi-intensive management systems. These and other factors influence the pattern of pneumonia complex in goats. We investigated the bronchoalveolar lavage fluid (BALf) cellular changes and haematological response in different types of caprine pneumonia in Nigeria. Haematological indices and BALf cells were analysed from 300 goats randomly selected from 700 goats comprising different breed, age and body scores. The pneumonia status was well characterised using standard pathological tools...
