Species richness and functional attributes of fish assemblages across a large-scale salinity gradient in shallow coastal areas by B. Koehler, M. Erlandsson, M. Karlsson, M. Karlsson, L. Bergström

“…Sample coverage exceeded 98.5 %, suggesting that undetected species represented <span class="inline-formula"><i>&lt;</i>1.5</span> % of incidences across the sub-basins, i.e. highly rare species. To compare sub-basins, we calculated standardized SR (SR<span class="inline-formula">_std</span>) and estimated SR (SR<span class="inline-formula">_est</span>). …”

Title not available by Reinaldo F.P. de Lucena, Camilla M. Lucena, Elcida L. Araújo, Ângelo G.C. Alves, Ulysses P. de Albuquerque

“…It has been suggested the use of methods that unite in their analysis both ethnobotanical and ecological aspects, like in the plants list from the priority index of conservation, which demonstrated to be more efficient to identify rare species in the local vegetation. The VU and the inventory in situ are more efficient to identify the most known and used species in the communities, however without analyzing these plants in the local vegetation.…”

The effect of low-abundance OTU filtering methods on the reliability and variability of microbial composition assessed by 16S rRNA amplicon sequencing by Maria Nikodemova, Maria Nikodemova, Elizabeth A. Holzhausen, Elizabeth A. Holzhausen, Courtney L. Deblois, Courtney L. Deblois, Jodi H. Barnet, Paul E. Peppard, Garret Suen, Kristen M. Malecki, Kristen M. Malecki

“…Excluding very low-abundance OTUs had a significant impact on alpha-diversity metrics sensitive to the presence of rare species (observed OTUs, Chao1) but had little impact on relative abundance of major phyla and families and alpha-diversity metrics accounting for both richness and evenness (Shannon, Inverse Simpson). …”

The Re-Identification of Previously Unidentifiable Clinical Non-Tuberculous Mycobacterial Isolates Shows Great Species Diversity and the Presence of Other Acid-Fast Genera by Yanua Ledesma, Gustavo Echeverría, Franklin E. Claro-Almea, Douglas Silva, Salomé Guerrero-Freire, Yeimy Rojas, Carlos Bastidas-Caldes, Juan Carlos Navarro, Jacobus H. de Waard

“…As most isolates also could not be identified confidently via <i>16S</i>, <i>hsp65</i>, or <i>rpoB</i> DNA sequencing and a nBLAST search analysis, we employed a phylogenetic method for their identification using the sequences of the <i>16S</i> rDNA, which resulted in the identification of most AFB and a <i>Mycobacterium</i> species diversity not found before in our laboratory. Most were rare species with only a few clinical reports. Moreover, although selected with the ZN staining as AFB, not all isolates belonged to the genus <i>Mycobacterium</i>, and we report for the first time in Latin America the isolation of <i>Nocardia puris</i>, <i>Tsukamurella pulmosis</i>, and <i>Gordonia sputi</i> from sputum samples of symptomatic patients. …”

A Case of <i>Aeromonas trota</i> in an Immunocompromised Patient with Diarrhea by Ana Fernández-Bravo, Isabel Fort-Gallifa, Frederic Ballester, Isabel Pujol, Frederic Gomez-Bertomeu, Mariola Domínguez, Miquel Micó, Eva Alcoceba, Josep Maria Simó-Sisó, Maria José Figueras

“…In conclusion, the recognition of an <i>Aeromonas</i> strain susceptible to ampicillin should alert the clinical microbiologist of the possible involvement of this rare species. Furthermore, the MALDI-TOF database should be updated indicating that the species <i>A. enteropelogenes</i>, is a synonym of <i>A. trota</i>.…”

Targeting Antigen to the Surface of EVs Improves the In Vivo Immunogenicity of Human and Non-human Adenoviral Vaccines in Mice by Carly M. Bliss, Andrea J. Parsons, Raffael Nachbagauer, Jennifer R. Hamilton, Federica Cappuccini, Marta Ulaszewska, Jason P. Webber, Aled Clayton, Adrian V.S. Hill, Lynda Coughlan

“…To overcome pre-existing immunity to commonly used human adenovirus serotype 5 (Ad5), vectors based on rare species or non-human Ads are being developed. However, these vectors often exhibit reduced potency compared with Ad5, necessitating the use of innovative approaches to augment the immunogenicity of the encoded antigen (Ag). …”

Zebra: Static and Dynamic Genome Cover Thresholds with Overlapping References by Daniel Hakim, Stephen Wandro, Karsten Zengler, Livia S. Zaramela, Brent Nowinski, Austin Swafford, Qiyun Zhu, Se Jin Song, Antonio Gonzalez, Daniel McDonald, Rob Knight

“…By compositing the metric across like samples, genome cover saturates even for rare species. We note that it is a threshold on saturated genome cover, not genome cover itself, which indicates a spurious reference hit or distant relative. …”

“…In this study, although Candida albicans was the predominant single species, non-C. albicans species constituted &gt;50% of isolates in 6 out of 10 years, and more rare species were present in the recent 5 years. The non-C. albicans species identified most frequently were Candida parapsilosis sensu stricto, Candida tropicalis, and Candida glabrata. …”
