The termite soil sheeting showed a significant increase in fungal density compared with the control soil. The structure of the fungal community of each sample obtained using plate count methods as well as Denaturing Gradient Gel Electrophoresis on rDNA 18S and rDNA 28S fragments was compared and is discussed. Although the structure and diversity of the fungal communities differ significantly depending on the technique used, the similarity dendograms obtained from the results using each of the three techniques showed the same sample groupings in all cases. The fungal communities of the biogenic structures were always closer to each other than they are to the control soil while the biogenic structures built by O. nilensis and M. subhyalinus were always closer to each other than to those built by A. guineensis. specialized Macrotermitinae termite sheeting fungal communities culturable fungi DGGE SENEGAL 074 45 3 899-914 2005 0361-6525 https://www.documentation.ird.fr/hor/PAR00000206 0361-6525 https://www.documentation.ird.fr/hor/PAR00000206 IRD - Base Horizon / Pleins textes 2006-03-29 2017-08-23 PAR00000206 fre
