“…Feline histoplasmosis is considered endemic in United States [ 1 , 11 ], and there are a few reports in cats around the world, as in Italy [ 12 ], Germany [ 2 ], Thailand [ 13 ], Japan [ 14 ], Costa Rica [ 8 ], among other countries, but little is known about the cases in Brazil. According to Table 1 , most of these reported cases occur in the state of Ceará [ [3] , [4] , [5] ], although no other cases have been found in the other Northeastern States. Additionally, histoplasmosis was reported in cats living in Southeastern Brazil, as in the states of Rio de Janeiro [ 6 , 7 ] and Minas Gerais [ 9 ], and in Southern Brazil, as in the Rio Grande do Sul [ 10 , 15 ], in which the fungal identifications were performed by phenotypic analysis by culture [ [3] , [4] , [5] , [6] , 10 , 15 ] or only cytology [ 7 , 9 ].…”
