Revisamos además ocho pacientes remitidos por colegas o presentados en congresos nacionales de dermatología, con lo cual el número de colombianos con lobomicosis es de 25, la tercera frecuencia despúes del Brasil y de Surinam. La Orinoquia y la Amazonia en pacientes indígenas y la Costa Pacífica en* la raza negra, son las áreas en las que predomina la lobomicosis. La complicación más frecuente es la ulceración que la hace confundir con leishmaniasis. En u n indígena se desarrolló u n carcinoma escamocelular sobre su lesión de lobomicosis, de dos años de evolución, que curó con la resección quirúrgica.

“…Lacaziosis was first identified in dolphins along the Gulf coast of Florida, USA (Migaki et al 1971), in the Indian River Lagoon, FL (Caldwell et al 1975) and in a dolphin from Marineland, FL (Woodard, 1972) in the 1970s. Cases were also reported from the Surinam River estuary (De Vries & Laarman 1973), the SpanishFrench coast (Symmers 1983), the intracoastal waterway in south Florida (Bossart 1984), the southern Brazilian coast (Simõse-Lopes et al 1993), and the Texas coast of the Gulf of Mexico (Cowan 1993).…”

This study represents the first systematic study of lacaziosis (lobomycosis) in bottlenose dolphins Tursiops truncatus in the Atlantic Ocean along the east-central coast of Florida, USA. Lacaziosis is a chronic infection of the skin caused by the fungus Lacazia loboi, which affects only dolphins and humans. Previous studies have shown a high prevalence (6.8 to 12.0%) of lacaziosis in resident dolphins from the adjacent Indian River Lagoon Estuary (IRL), where the disease is endemic. We examined the prevalence of lacaziosis in this coastal area using photo-identification data collected between 2002 and 2008 to determine the prevalence of lacaziosis in coastal dolphins using photographic methodology shown to have high sensitivity and specificity in prior research. The prevalence of skin lesions compatible with lacaziosis estimated from photographic data was 2.1% (6/284), approximately 3 times lower than that described for the estuarine population using similar methods. To exclude potential bias introduced by differences in study duration and survey effort among areas, an 18 mo period when effort was most equal (January 2006 to June 2007) was chosen for statistical comparison. The prevalence of lacaziosis estimated from photographic data was significantly lower (3.8%: n = 6/160) in the Atlantic Ocean compared to the IRL (12.0%: n = 20/167) (risk ratio = 3.19, 95% CI 1.32 to 7.75, p < 0.01 by chi-square analysis). The lower prevalence of lacaziosis in dolphins found in the Atlantic Ocean and the overall lack of movement of dolphins between these habitats suggests that environmental conditions within the estuary may favor viability of L. loboi, and/or that immune compromise in resident estuarine dolphins is a precursor to the disease.

“…Transmission in both humans and dolphins is thought to be facilitated by trauma, injuries, or abrasions to the skin serving as portals of entry for the organism and may be correlated with immunodeficiency (Bossart, 1984;Pecher and Fuchs, 1988;Funchs et al, 1990;Reif et al, 2006Reif et al, , 2008Xavier et al, 2006). In dolphins, the disease is found to occur on the head, flippers, flukes, dorsal fin, and peduncle (Caldwell et al, 1975;Dudok Van Heel, 1977) and has been documented along the coasts of the Gulf of Mexico, South America, and the coasts of Florida (Migaki et al, 1971;De Vries and Laarman, 1973;Caldwell et al, 1975;Bossart, 1984;Cowan, 1993;Simõ se-Lopes and Paula, 1993). The lesions are generally limited to the skin and present as a chronic proliferative and ulcerated dermatitis and cellulitis.…”

“…Many of the published accounts have come from the IRL and east coast dolphins (Caldwell et al, 1975;Bossart, 1984;Bossart et al, 2003;Reif et al, 2006). Anecdotal reports have documented the disease throughout the lagoon for decades (Caldwell et al, 1975;Odell, pers. comm.).…”
