Four species of Rosellinia collected in Las Yungas ecoregion are reported for the first time Argentine funga: R. hyalospora, longispora, rickii and stenasca. These described illustrated by photographs. In addition, a distribution map with new findings dichotomous key to recognized country presented. .

Poultry is an important source of protein and income for several households in Nigeria. However, the poultry industry threatened by outbreaks infectious diseases which may spread through interaction wild or migratory birds with poultry. The study aimed to detect morphologically identify Eimeria species from faecal samples chickens, pigeons African fire finches collected different farms Kaduna m...

Coccidiosis is an intestinal disease of chickens of major economic importance to broiler industries worldwide. Species of coccidia found in chickens include Eimeria acervulina, Eimeria brunetti, Eimeria maxima, Eimeria mitis, Eimeria necatrix, Eimeria praecox, and Eimeria tenella. In recent years, polymerase chain reaction (PCR) has been developed to provide accurate and rapid identification of...

INTRODUCTION It has long been accepted that the resistance developed by fowls to reinfection with the various species of Eimeria which parasitize them is species specific (Tyzzer, Theiler & Jones, 1932; Johnson, 1938). However, careful examination of data obtained in this laboratory suggested that this might not be true for those species which appear to have similar properties. A preliminary re...

A new method for computing evolutionary distances between DNA sequences is proposed. Contrasting with classical methods, the underlying model does not assume that sequence base compositions (A, C, G, and T contents) are at equilibrium, thus allowing unequal base compositions among compared sequences. This makes the method more efficient than the usual ones in recovering phylogenetic trees from ...

Soil and rock surfaces support microbial communities involved in mineral weathering processes. Using selective isolation, fungi were obtained from limestone surfaces of Mayan monuments in the semi-arid climate at Yucatan, Mexico. A total of 101 isolates representing 53 different taxa were studied. Common fungi such as Fusarium, Pestalotiopsis, Trichoderma, and Penicillium were associated with s...
