The first study of the aphid fauna from Chukotka Autonomous Okrug has been made; 18 species are reported from this territory, the most north-eastern of Russia and of the Palaeartic Region. Five new species are described: Aphis aquilonalis sp. nov. on Rumex arcticus Trautv.; Aphis beringiensis sp. nov. were collected by yellow trap; Macrosiphoniella (Asterobium) jaroslavi sp. nov. on Artemisia a...
Introduction The United States Department of Agriculture (USDA) Animal and Plant Inspection Service (APHIS) announced the first diagnosed case of PEDV in U.S. swine in Iowa on May 17, 2013. PEDV subsequently spread rapidly among the domestic swine herds throughout the United States. As of August 20, 2014, PEDV had been detected in 30 U.S. states affecting more than seven million pigs since the ...
The frequencies at which vegetative cells and spores of Clostridium botulinum strains 56A, 62A, 17409A, 25763A, 213B, B-aphis, and 169B formed colonies on agar media containing 0, 10(sup2), 10(sup3), and 10(sup4) IU of nisin per ml at 30(deg)C were determined. Strain 56A had the highest frequencies of nisin resistance, while strains 62A, 169B, and B-aphis had the lowest. For most strains, spore...
The gammaproteobacterium Serratia symbiotica is one of the major secondary symbionts found in aphids. Here, we report the draft genome sequence of S. symbiotica strain CWBI-2.3(T), previously isolated from the black bean aphid Aphis fabae. The 3.58-Mb genome sequence might provide new insights to understand the evolution of insect-microbe symbiosis.
During the study on endophytic fungi of grapevine (Vitis vinifera L.), 655 fungal isolates were obtained and studied taxonomically. Based on morphological and ITS sequences data, 15 species belonging to 10 genera including Alternaria brassicicola, A. chlamydospora, A. malorum, A. atra, Arthrinium phaeospermum, A. sacchari, Aspergillus nidulans, A. wentii, Beauveria bassiana, Cheatomium elatum, ...
