The objective of the monitoring was to describe the reef fish communities and to establish whether populations within the marine reserve were demonstrating any changes in abundance or size that could be attributable to the removal of fishing pressure. The underwater visual census method was used to survey the four lo- cations (marine reserve and three non-reserve locations). It was found that all four locations were characterised by moderate densities of spot- ties, scarlet wrasse and reef-associated planktivores such as blue maomao, sweep and butterfly perch. -

The number of substitutions at the diverging point of Dictyoglomus is insufficient to show the relationships in a single gene comparison-based analysis. Hence, we studied its Keywords: evolutionary trait based on whole-genome comparison. Both gene content and orthologous protein sequence Whole-genome comparison Dictyoglomus comparisons indicated that Dictyoglomus is most closely related to the phylum Thermotogae and it forms a Bacterial systematics monophyletic group with Coprothermobacter proteolyticus (a constituent of the phylum Firmicutes) and Coprothermobacter proteolyticus Thermotogae. Our findings indicate that C. proteolyticus does not belong to the phylum Firmicutes and that the Thermotogae phylum Dictyoglomi is not closely related to either the phylum Firmicutes or Synergistetes but to the phylum Thermotogae. © 2011 Elsevier Inc. -
METABOLIC EVOLUTION in GALDIERIA SULPHURARIA By

TERNES Date of Degree: MAY, 2015 Title of Study: METABOLIC EVOLUTION IN GALDIERIA SULPHURARIA Major Field: PLANT SCIENCE Abstract: The thermoacidophilic, unicellular, red alga Galdieria sulphuraria possesses characteristics, including salt and heavy metal tolerance, unsurpassed by any other alga. Like most plastid bearing eukaryotes, G. sulphuraria can grow photoautotrophically. Additionally, it can also grow solely as a heterotroph, which results in the cessation of photosynthetic pigment biosynthesis. The ability to grow heterotrophically is likely correlated with G. sulphuraria ’s broad capacity for carbon metabolism, which rivals that of fungi. Annotation of the metabolic pathways encoded by the genome of G. sulphuraria revealed several pathways that are uncharacteristic for plants and algae, even red algae. Phylogenetic analyses of the enzymes underlying the metabolic pathways suggest multiple instances of horizontal gene transfer, in addition to endosymbiotic gene transfer and conservation through ancestry. Although some metabolic pathways as a whole appear to be retained through ancestry, genes encoding individual enzymes within a pathway were substituted by genes that were acquired horizontally from other domains of life. Thus, metabolic pathways in G. sulphuraria appear to be composed of a ‘metabolic patchwork’, underscored by a mosaic of genes resulting from multiple evolutionary processes. -

Coxiella burnetii, is a Gram-negative obligate intracellular bacterium, adapted to thrive within the phagolysosome of the phagocyte. Humans become infected primarily by inhaling aerosols that are contaminated with C. burnetii. Ingestion (particularly drinking raw milk) and person-to-person transmission are minor routes. Animals shed the bacterium in urine and feces, and in very high concentrations in birth by-products. The bacterium persists in the environment in a resistant spore-like form which may become airborne and transported long distances by the wind. It is considered primarily as occupational disease of workers in close contact with farm animals or processing their be commenced immediately whenever Q fever is suspected.

This study evaluated the cultivable Vibrio community in the Guanabara Bay (GB), a recreational, yet heavily polluted estuary in Rio de Janeiro, Brazil. Over one year, 66 water samples from three locations along a pollution gradient were investigated. Isolates were identified by MALDI-TOF mass spectrometry, revealing 20 Vibrio species, including several potential pathogens. Antimicrobial susceptibility testing confirmed resistance to aminoglycosides, beta-lactams (including carbapenems and third-generation cephalosporins), fluoroquinolones, sulfonamides, and tetracyclines.

Genomic Signatures of Predatory Bacteria

Wise Faculty of Life Sciences, Tel Aviv University, Tel Aviv, Israel Predatory bacteria are taxonomically disparate, exhibit diverse predatory strategies and are widely distributed in varied environments. To date, their predatory phenotypes cannot be discerned in genome sequence data thereby limiting our understanding of bacterial predation, and of its impact in nature. Here, we define the ‘predatome,’ that is, sets of protein families that reflect the phenotypes of predatory bacteria. The proteomes of all sequenced 11 predatory bacteria, including two de novo sequenced genomes, and 19 non-predatory bacteria from across the phylogenetic and ecological landscapes were compared. Protein families discriminating between the two groups were identified and quantified, demonstrating that differences in the proteomes of predatory and non-predatory bacteria are large and significant. This analysis allows predictions to be made, as we show by confirming from genome data an over-looked bacterial predator. The predatome exhibits deficiencies in riboflavin and amino acids biosynthesis, suggesting that predators obtain them from their prey. In contrast, these genomes are highly enriched in adhesins, proteases and particular metabolic proteins, used for binding to, processing and consuming prey, respectively. -

Ehrlichiosis and Anaplasmosis Are Tick-Borne Diseases Caused by Obligate Anaplasmosis: Intracellular Bacteria in the Genera Ehrlichia and Anaplasma
Ehrlichiosis and Importance Ehrlichiosis and anaplasmosis are tick-borne diseases caused by obligate Anaplasmosis: intracellular bacteria in the genera Ehrlichia and Anaplasma. These organisms are widespread in nature; the reservoir hosts include numerous wild animals, as well as Zoonotic Species some domesticated species. For many years, Ehrlichia and Anaplasma species have been known to cause illness in pets and livestock. The consequences of exposure vary Canine Monocytic Ehrlichiosis, from asymptomatic infections to severe, potentially fatal illness. Some organisms Canine Hemorrhagic Fever, have also been recognized as human pathogens since the 1980s and 1990s. Tropical Canine Pancytopenia, Etiology Tracker Dog Disease, Ehrlichiosis and anaplasmosis are caused by members of the genera Ehrlichia Canine Tick Typhus, and Anaplasma, respectively. Both genera contain small, pleomorphic, Gram negative, Nairobi Bleeding Disorder, obligate intracellular organisms, and belong to the family Anaplasmataceae, order Canine Granulocytic Ehrlichiosis, Rickettsiales. They are classified as α-proteobacteria. A number of Ehrlichia and Canine Granulocytic Anaplasmosis, Anaplasma species affect animals. A limited number of these organisms have also Equine Granulocytic Ehrlichiosis, been identified in people. Equine Granulocytic Anaplasmosis, Recent changes in taxonomy can make the nomenclature of the Anaplasmataceae Tick-borne Fever, and their diseases somewhat confusing. At one time, ehrlichiosis was a group of Pasture Fever, diseases caused by organisms that mostly replicated in membrane-bound cytoplasmic Human Monocytic Ehrlichiosis, vacuoles of leukocytes, and belonged to the genus Ehrlichia, tribe Ehrlichieae and Human Granulocytic Anaplasmosis, family Rickettsiaceae. The names of the diseases were often based on the host Human Granulocytic Ehrlichiosis, species, together with type of leukocyte most often infected. -
