What causes lobomycosis?
What causes lobomycosis?
The causative organism is Lacazia loboi (formerly Loboa loboi), a dimorphic fungus found in soil, vegetation, and water. Infection occurs through traumatic implantation of the fungus into the skin. Lobomycosis affects both humans and dolphins.
How is lobomycosis treated?
Combination itraconazole and clofazimine has been used in the treatment of lobomycosis on the face, with no relapse after 3-year follow up. Patients with lobomycosis and concurrent leprosy respond to multibacillary therapy, with reduction of pruritus and the size of mycotic nodules.
What is loboa loboi?

How is Lacazia Loboi transmitted?
Cases of lobomycosis have been reported only in dolphins and humans. Its prevalence is higher among men who are active in the forest, such as rubber tappers, bushmen, miners, and Indian men. It is recognized that the traumatic implantation of the fungus on the skin is the route by which humans acquire this infection.
What is mucormycosis and what area of the body is most commonly infected?
Mucormycosis mainly affects people who have health problems or take medicines that lower the body’s ability to fight germs and sickness. It most commonly affects the sinuses or the lungs after inhaling fungal spores from the air.
What does Paracoccidioidomycosis mean?
Paracoccidioidomycosis is an infection caused by the fungus Paracoccidioides. This fungus lives in parts of Central and South America. Anyone who lives in or visits areas where Paracoccidioides lives can get paracoccidioidomycosis, but it most often affects men who work outdoors in rural areas.
What causes sporotrichosis?
Sporotrichosis (also known as “rose gardener’s disease”) is an infection caused by a fungus called Sporothrix. This fungus lives throughout the world in soil and on plant matter such as sphagnum moss, rose bushes, and hay. People get sporotrichosis by coming in contact with the fungal spores in the environment.
What is Mycetoma?
Mycetoma is a disease caused by certain types of bacteria and fungi found in soil and water. These bacteria and fungi may enter the body through a break in the skin, often on a person’s foot.
Is Lacazia Loboi a parasite?
The etiologic agent of Jorge Lobo’s disease (lacaziosis), Lacazia loboi is an uncultivated fungal pathogen of humans and dolphins causing cutaneous and subcutaneous infections and, rarely, visceral involvement. This anomalous pathogen is restricted to Mexico, Central America, and South America.
What type of infection is histoplasmosis?
Histoplasmosis is an infection caused by a fungus called Histoplasma. The fungus lives in the environment, particularly in soil that contains large amounts of bird or bat droppings.
Is mucormycosis curable?
Successful management of mucormycosis requires early diagnosis, reversal of underlying predisposing risk factors, surgical debridement and prompt administration of active antifungal agents. However, mucormycosis is not always amenable to cure.
Why do you get mucormycosis after Covid?
During the second wave of the COVID-19 pandemic in India, an unprecedented surge in cases of mucormycosis was observed: immune dysregulation caused by the SARS-CoV-2 and the use of broad-spectrum antibiotics and corticosteroids—particularly in patients with poorly controlled diabetes with ketoacidosis—is likely to have …
Are there any cases of lobomycosis in humans?
Abstract: Lobomycosis is a subcutaneous mycosis of chronic evolution caused by the Lacazia loboi fungus. Its distribution is almost exclusive in the Americas, and it has a particularly high prevalence in the Amazon basin. Cases of lobomycosis have been reported only in dolphins and humans.
What kind of disease does Lacazia loboi cause?
Lobomycosis is a fungal infection caused by Lacazia loboi. This disease affects primarily the subcutaneous tissue manifested by a chronic granulomatous reaction, full of parasites, in the dermis. Keloid-like lesions are the most common clinical presentation. 1 – 3
How big is a la loboi yeast cell?
Regular, round-shaped yeasts, isolated or in a chain, are the typical presentation of La. loboi in tissues. The size is approximately 6 × 13.5 × 11 μm, with a birefringent membrane and thick wall containing melanin.
