Lobomycosis and lobomycosis-like diseases (LLD) (also: paracoccidioidomycosis) are chronic cutaneous infections that affect Delphinidae in tropical and subtropical regions worldwide. In the Americas, these diseases have been relatively well-described, but gaps still exist in our understanding of their distribution across the continent. Here we report on LLD affecting inshore bottlenose dolphins Tursiops truncatus from the Caribbean waters of Belize and from the eastern tropical Pacific Ocean off the southwestern coast of Mexico.

Lobomycosis is a chronic skin mycosis endemic in Amazon regions characterized by chronic nodular or keloidal lesions caused by , an uncultivable fungus. Imported cases in nonendemic countries are rare and diagnosed after years. We describe a case of lobomycosis in a healthy 55-year-old Italian traveler who had acquired the infection during 5-day-honeymoon in the Amazon region of Venezuela in 1999. Read More

From 2003 to 2015, 360 free-ranging Atlantic bottlenose dolphins Tursiops truncatus inhabiting the Indian River Lagoon (IRL, n = 246), Florida, and coastal waters of Charleston (CHS, n = 114), South Carolina, USA, were captured, given comprehensive health examinations, and released as part of a multidisciplinary and multi-institutional study of individual and population health. The aim of this review is to summarize the substantial health data generated by this study and to examine morbidity between capture sites and over time. The IRL and CHS dolphin populations are affected by complex infectious and neoplastic diseases often associated with immunologic disturbances. Read More

Background: There is a worrying lack of epidemiological data on the geographical distribution and burden of subcutaneous mycoses in Peru, hindering the implementation of surveillance and control programs.
Objectives: This study aimed to estimate the disease burden of subcutaneous mycoses in Peru and identify which fungal species were commonly associated with these mycoses.
Methods: We performed a meta-analysis after a systematic review of the published literature in PubMed, LILACS, and SciELO to estimate the burden of subcutaneous mycoses in 25 regions in Peru. Read More

Since the initial description of the granular cell tumor in 1926, numerous other neoplasms, both benign and malignant, have been described to exhibit granular cell change. In most cases, diagnosis remains straightforward via recognition of retained histopathological morphology of the archetypal tumor, despite the presence of focal granular appearance. However, tumors with granular cell differentiation can present a diagnostic challenge either by mimicking alternative diagnoses, or by failing to exhibit architectural clues of the primary entity, thus requiring an immunohistochemical work-up.

Cutaneous granulomas in dolphins were believed to be caused by Lacazia loboi, which also causes a similar disease in humans. This hypothesis was recently challenged by reports that fungal DNA sequences from dolphins grouped this pathogen with Paracoccidioides brasiliensis. We conducted phylogenetic analysis of fungi from 6 bottlenose dolphins (Tursiops truncatus) with cutaneous granulomas and chains of yeast cells in infected tissues. Read More

Four groups were composed: G1: inoculated with restricted diet, G2: not inoculated with restricted diet, G3: inoculated with regular diet, G4: not inoculated with regular diet. Once malnutrition had been imposed, the animals were inoculated intradermally in the footpad and after four months, were sacrificed for the excision of the footpad, liver and spleen. Read More

Subcutaneous mycoses are a group of fungal infections of dermis and subcutaneous tissue which consist of sporotrichosis, chromoblastomycosis, phaeohyphomycosis, hyalohyphomycosis, mycetoma, subcutaneous zygomycosis, rhinosporidiosis, lobomycosis and disseminated penicilliosis. A total of 46 consecutive patients with clinically suspected subcutaneous mycoses attending various departments of Assam Medical College and Hospital were included in this prospective study to know the prevalence of subcutaneous mycoses in this eastern part of Assam. Direct microscopy in 10 and 40 % KOH, histopathological examination of biopsied tissue, colony characteristics on Sabourauds dextrose agar media both at 25 and 37 °C and detailed morphology of each fungus on lactophenol cotton blue mount were the basis of identification of the fungi.

Lobomycosis, a fungal disease of the skin and subcutaneous tissues caused by Lacazia loboi, is sometimes referred to as a zoonotic disease because it affects only specific delphinidae and humans; however, the evidence that it can be transferred directly to humans from dolphins is weak. Dolphins have also been postulated to be responsible for an apparent geographic expansion of the disease in humans. Morphological and molecular differences between the human and dolphin organisms, differences in geographic distribution of the diseases between dolphins and humans, the existence of only a single documented case of presumed zoonotic transmission, and anecdotal evidence of lack of transmission to humans following accidental inoculation of tissue from infected dolphins do not support the hypothesis that dolphins infected with L.

Lobomycosis, a disease caused by the uncultivable dimorphic onygenale fungi Lacazia loboi, remains to date as an enigmatic illness, both due to the impossibility of its aetiological agent to be cultured and grown in vitro, as well as because of its unresponsiveness to specific antifungal treatments. It was first described in the 1930s by Brazilian dermatologist Jorge Lobo and is known to cause cutaneous and subcutaneous localised and widespread infections in humans and dolphins. Soil and vegetation are believed to be the chief habitat of the fungus, however, increasing reports in marine mammals has shifted the attention to the aquatic environment. Read More

These diseases are among the so called tropical diseases found in countries of tropical climate, usually infections and infestations considered exotic and rare in European and North American countries. It is extremely important for doctors of all countries to be able to provide correct pre travel counseling and to make early diagnosis and treatment, thus avoiding dissemination of these dieases to non endemic areas.

Lacaziosis (lobomycosis; Lacazia loboi) is a fungal skin disease that naturally occurs only in humans and dolphins. The first reported case of lacaziosis in a bottlenose dolphin Tursiops truncatus occurred in 1970 in Sarasota Bay, Florida, USA, and subsequent photo-ID monitoring of the Sarasota Bay dolphin population has revealed persistence of the disease. The objectives of this study were to estimate lacaziosis prevalence (P) in 2 bottlenose dolphin populations on the west coast of Florida (Sarasota Bay and Charlotte Harbor) and compare disease occurrence to other published estimates of lacaziosis in dolphin populations across the globe.
