Phylogenetic analysis of HA, neuraminidase, and concatenated internal genes revealed a very similar topology, with viruses under study forming a separate cluster, branching outside the A(H1N1 pdm09 isolates recognized until 2014.
10 (27%) ESBL isolates recognized among the 37 Klebsiella pneumoniae and 2 (5.4%) are CRE. 4 MRSA isolates (30.8%) identified among the Staphylococcus aureus.
The variety of serotypes within the same patient suggests, given the short time frame between some repeated cultures, likely several strains of pneumococci were present but with only a single isolate recognized as opposed to strain displacement within a single patient.
It was from this ore, studied by Axel Fredrik Cronstedt, that nickel was isolated and recognized as a new element in 1751.
About four-fifths of Earth's atmosphere is nitrogen, which was isolated and recognized as a specific substance during early investigations of the air.
Nickel was used industrially as an alloying metal almost 2,000 years before it was isolated and recognized as a new element.
In 1991, the agent was isolated and recognized as a novel pathogen, Ehrlichia chaffeensis (5 ).
Results showed that both isolated VHHs recognize three serotypes (1/2a, 1/2b, and 4b), which are responsible for more than 95% of documented human listeriosis cases.
Using a carefully designed selection strategy, VHH antibody fragments from a non-immune phage display library were isolated that recognize the KDEL sequence at the C-terminus of proteins, irrespective of the protein context.
The sentiment that speciation is mysterious comes, I argue, from the biological species concept, which requires populations to be reproductively isolated before recognizing them as species.
