ABSTRACT
BACKGROUND: Ticks are implicated as hosts to a wide range of animal and human pathogens. The full range of microbes harbored by ticks has not yet been fully explored. METHODS: As part of a viral surveillance and discovery project in arthropods, we used unbiased high-throughput sequencing to examine viromes of ticks collected on Long Island, New York in 2013. RESULTS: We detected and sequenced the complete genome of a novel rhabdovirus originating from a pool of Amblyomma americanum ticks. This virus, which we provisionally name Long Island tick rhabdovirus, is distantly related to Moussa virus from Africa. CONCLUSIONS: The Long Island tick rhabdovirus may represent a novel species within family Rhabdoviridae.

The complete genome sequences of Brevundimonas naejangsanensis strain FS1091 and Bacillus amyloliquefaciens strain FS1092, which were isolated from a commercial fresh-cut-produce-processing facility, were determined. Both FS1091 and FS1092 have one circular chromosome of approximately 3.15 and 4.24 Mb, respectively.
ABSTRACT
Salmonellosis is a disease with a high incidence worldwide, and Salmonella enterica subsp. enterica serovar Typhimurium is one of the most clinically important serovars. We report here the draft genome sequences of 20 S. Typhimurium strains isolated from swine in Santa Catarina, Brazil. These draft genomes will improve our understanding of S. Typhimurium in Brazil.
ABSTRACT
Campylobacter jejuni is a major zoonotic pathogen that causes foodborne gastroenteritis worldwide. However, clinical cases of campylobacteriosis have been underreported and underdiagnosed in Brazil. Herein, we describe the draft genome sequences of 116 C. jejuni strains isolated from diverse sources in Brazil.
ABSTRACT
Yersinia enterocolitica-like strains are usually understudied. In this work, we reported the draft genome sequences of two Yersinia frederiksenii, two Yersinia intermedia, and two Yersinia kristensenii strains isolated from humans, animals, food, and the environment in Brazil. These draft genomes will provide better molecular characterizations of these species.
ABSTRACT
Histamine-producing bacteria are responsible for scombrotoxin (histamine) fish poisoning, a leading cause of fish poisoning in the United States. We report here the first draft genomes of three histamine-producing Morganella psychrotolerans strains, isolated from tuna and mahi-mahi.
ABSTRACT
Gastrointestinal stromal tumors (GISTs) are generally CD117-positive and KIT or PDGFRA mutation-driven mesenchymal tumors of the gastrointestinal tract, probably originating in interstitial cells of Cajal or related precursors. CD117 is the best diagnostic marker for GISTs, but 5-10% are negative. Staining pattern may be cytoplasmic, membrane, and paranuclear (Golgi pattern). PDGFRA expression can be located in the cytoplasm, membrane, and paranuclear region (Golgi pattern), but the lack of specificity, ubiquity of the staining, and technical problems have pushed it a second plane. In GISTs, the staining pattern of PKCO is cytoplasmic, diffuse, and granular, although a Golgi pattern may be seen. Global expression varies. The staining pattern of DOG1 varies from cytoplasmic to membranous, with usually strong, diffuse intensity. The positivity rate is almost identical in some series to CD117 positivity. Currently, it is considered the most specific and sensitive marker for GIST. The current panel for GIST includes CD117, smooth muscle actin, CD34, desmin, and S-100. Some authors also include PDGFRA, PKC0, and DOG1. The last two can be of value in a subset of GISTs, mainly in CD117-negative cases.
