New records of Histoplasma capsulatum from wild animals in the Brazilian amazon
Twenty-eight isolates of Histoplasma capsulatum were obtained from eight species of forest mammals from the States of Amazonas, Pará and Rondônia in the Amazon Region of Brazil. Primary isolates were obtained by inoculating triturated liver and spleen tissue intradermally and intraperitoneally in ha...
