Garlic (Allium sativum L.) is grown all over the world as seasoning and medicinal vegetable since 3,000 BC. Allicin is the main component of garlic, being attributed to it the most of its biological activities, such as bactericidal, antifungal and antiviral actions. However, other compounds of garlic present antioxidant, hypocholesterolemic, vasodilator activities, protective action against different types of cancer, and immunomodulatory. Fungal infections are important causes of morbidity and mortality in people mainly in immunosuppressed ones. Sporothrix schenckii, the causing agent of Sporotrichosis (most common subcutaneous mycosis in Latin America), is dimorphic fungus, of saprophytic life in soil or plants, infecting people and animals mainly through skin injuries and bruises. The main of this work was to evaluate the influence of garlic consuming on immune modulation of healthy and infected Swiss mice in induced way by S. schenckii, since these animals functioning of peritoneal macrophages as well as the nitric oxide and cytokines' production (IL-1β, IL-10 and IL-12) and to evaluate the antifungal potential of garlic with S. schenckii through minimum inhibitory concentration test and colony-forming units. The results showed that garlic offers antifungal potential with S. schenckii. The oral taking of garlic extracts influences the releasing of cytokines by macrophages, regular consuming shows anti-inflammatory effect, and its acute use may take to an inflammatory response. Mice that consumed garlic responded more effectively to fight against the infection.Keywords: garlic, macrophage, Sporothrix schenckii, sporotrichosis, interleukin.Controle da infecção fúngica pelos extratos de alho (Allium sativum L.) e modulação da atividade de macrófagos peritoneais em modelo murino de esporotricose ResumoO alho (Allium sativum L.) é cultivado em todo o mundo como hortaliça condimentar e medicinal desde 3.000 a. C. A alicina é o principal componente do alho, sendo atribuída a ela a maior parte das suas atividades biológicas, dentre elas as ações bactericida, antifúngica e antiviral. Porém, outros compostos do alho apresentam atividade antioxidante, hipocolesterolemiante, vasodilatadora, ação protetora contra diversos tipos de câncer e imunomoduladora. As infecções por fungos são causas importantes de morbidade e mortalidade no homem principalmente em indivíduos imunossuprimidos. O Sporothrix schenckii, agente causal da esporotricose (micose subcutânea mais comum na América Latina), é fungo dimórfico, de vida saprofítica no solo ou em vegetais, infectando homens e os animais principalmente através de lesões e arranhões na pele. O objetivo desse trabalho foi avaliar a influência do consumo de alho na imunomodulação de camundongos Swiss saudáveis e infectados de forma induzida por S. schenckii, a partir do estado funcional dos macrófagos peritoneais desses animais quanto à produção de óxido nítrico e das citocinas (IL-1β, IL-10 e IL-12) e avaliar o potencial antifúngico do alho frente ao S. schenckii por meio de...
