Seroepidemiological survey on sporotrichosis-infection in rural areas of the south of Minas Gerais State, Brazil

Abstract

Sporotrichosis is a subcutaneous mycosis caused by traumatic inoculation into the skin by fungi species of the genus Sporothrix. The disease has different clinical manifestations (cutaneous, lymphocutaneous, and disseminated), and can also progress to a systemic infection. Despite having a worldwide distribution, sporotrichosis is most prevalent in tropical and subtropical countries. In Brazil, reports of the disease are higher frequent, where cases of the disease were found in Rio de Janeiro, Sao Paulo, Curitiba, Pernambuco, and Paraiba, among others. Certain groups of people may be more exposed to the causative agent of disease, such as residents of rural areas. Thus, this work aimed to carry out a seroepidemiological survey of the prevalence of sporotrichosis in four rural locations in the south of Minas Gerais State, Brazil. In this study, we used an indirect ELISA test in the survey on the prevalence of sporotrichosis. Data obtained in this study evaluated a population of 631 individuals and showed a prevalence of 44.69%. The distribution of seroprevalence of sporotrichosis with respect to age groups and gender showed no significant statistical difference. Thus, we found a high seroprevalence of sporotrichosis-infection in rural regions of southern Minas Gerais State, Brazil, with no difference in prevalence in relation to gender and age.

“…A total of 68 publications with 11,050 cases of sporotrichosis were found in South America [ 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 79 , 80 , 81 , 82 , 83 , 84 , 85 , 86 , 87 , 88 , 89 , 90 , 91 , 92 , 93 , 94 , 95 , 96 , 97 , 98 , 99 , 100 , 101 , 102 , 103 , 104 , 105 , 106 , 107 , 108 , 109 , 110 , 111 , 112 , 113 , 114 , 115 , 116 , 117 , 118 , 119 , 120 …”

Clinical and Epidemiological Characteristics of Sporotrichosis in a Reference Center of Uruguay

“…conidia into skin or mucosa [ 11 , 12 , 13 , 14 , 15 , 16 ]. Infection with this fungus is related to areas of the body exposed to trauma [ 17 , 18 ]. Historically, sporotrichosis was known as the “gardener’s mycosis”, classically associated with soil manipulation activities, whether due to occupational or leisure reasons [ 9 , 19 , 20 ].…”

“…Recently, genetic sequencing studies confirmed that S. schenckii is a complex composed of cryptic species: S. albicans, S. brasiliensis, S. globosa, S. luriei, S. mexicana, and S. schenckii [ 17 , 31 , 32 , 33 ]. S. brasiliensis and S. schenckii are common in Brazil, S. mexicana is present in Mexico, and S. globosa is common in countries such as China, India, Japan, the USA, Spain and Italy [ 17 , 34 ].…”

Interestingly, it arises that the crypticas species have a different pathogenic potential and S. schenckii causes a benign chronic subcutaneous mycosis, S. brasiliensis is highly virulent, and S. globosa causes mainly fixed cutaneous lesions [ 5 , 35 , 36 ].…”

Special issue on sporotrichosis: challenges to deal with the new emerging pathogenic species

“…Baptista et al [9] report here its applicability for feline sporotrichosis diagnosis and/or therapeutic follow-up. Grisolia et al [10] present a seroepidemiological survey of the prevalence of sporotrichosis in four rural locations in the south of Minas Gerais state, Brazil.…”
