The spatial pattern of antibiotic resistance in culturable sediment bacteria from four freshwater streams was examined. Previous research suggests that the prevalence of antibiotic resistance may increase in populations via indirect or cose...
Leaf-associated bacterial and fungal taxa shifts in response to larvae of the tree hole mosquito, Ochlerotatus triseriatus [0.03%]

Larvae of the eastern tree hole mosquito, Ochlerotatus triseriatus (Say), and related container-breeding species are known to feed upon substrate-associated microorganisms. Although the importance of these microbial resources to larval grow...

Among 106 filamentous fungi isolated from poultry farm waste, 13 species belonging to seven genera (Aspergillus, Acremonium, Alternaria, Beauvaria, Curvularia, Paecilomyces, and Penicillium) were able to grow and produce keratinase in stati...
Phylogenetic and physiological diversity of bacteria isolated from Puruogangri ice core [0.03%]

X F Zhang et al.
The microbial abundance, the percentage of viable bacteria, and the diversity of bacterial isolates from different regions of a 83.45-m ice core from the Puruogangri glacier on the Tibetan Plateau (China) have been investigated. Small subun...

Effects of deposit-feeding macrofauna on benthic bacteria, viruses, and protozoa in a silty freshwater sediment [0.03%]
底栖宏食腐动物对淡水硅泥沉积物中细菌、病毒和原生动物的影响

Claudia Wieltschnig et al.
In microcosm experiments, we simultaneously tested the effects of increased numbers of deposit-feeding macrofauna (chironomids, oligochaetes and cladocerans) on the standing stock, activities and interactions of heterotrophic bacteria, viru...
Two distinct Photobacterium populations thrive in ancient Mediterranean sapropels [0.03%]
两种不同的Photobacterium种群在古老的地中海sapropel中茁壮成长

Jacqueline Süss et al.
Eastern Mediterranean sediments are characterized by the periodic occurrence of conspicuous, organic matter-rich sapropel layers. Phylogenetic analysis of a large culture collection isolated from these sediments revealed that about one thir...
Role of productivity and protozoan abundance for the occurrence of predation-resistant bacteria in aquatic systems [0.03%]
生产品质和原生动物丰度对水体中抗菌性细菌产生的贡献

Johanna Thelaus
Top-down control of lower trophic levels, e.g., bacteria, has been suggested to increase along aquatic productivity gradients. The response by the bacterial community may be to become more predation resistant in highly productive environmen...
Effects of exogenous melatonin and tryptophan on fecal shedding of E. coli O157:H7 in cattle [0.03%]
外源性褪黑素和色氨酸对牛肉牛体内的E.coli O157:H7粪便排泄量的影响研究
Tom S Edrington,Todd R Callaway,Dennis M Hallford et al.
Tom S Edrington et al.
Fecal prevalence of Escherichia coli O157 in ruminants is highest in the summer decreasing to very low levels in the winter. We hypothesize that this seasonal variation is a result of physiological responses within the host animal to changi...
Salinity tolerance of the chlorophyll b-synthesizing cyanobacterium Prochlorothrix hollandica strain SAG 10.89 [0.03%]
产叶绿素b的蓝细菌光合衣藻荷兰菌株SAG 10.89耐盐性的研究

Ingo Bergmann et al.
Ecophysiological investigations on the salinity acclimation of the cyanobacterium Prochlorothrix hollandica SAG 10.89 led to significantly revised salinity tolerance limits. Besides potential effects of cultivation techniques, clear ion com...
