A remarkable specimen of Mesolimulus from the Upper Jurassic (Kimmeridgian) of Nusplingen, Germany, preserves the musculature of the prosoma and associated microbes in three dimensions in calcium phosphate (apatite). The musculature of Mesolimulus conforms closely to that of modern horseshoe crabs. Associated with the muscles are patches of mineralized biofilm with spiral and coccoid forms. Thi...

Four strains of Gram-negative, rod-shaped, moderately halophilic bacteria, Group A, and eleven strains of strictly aerobic, extremely halophilic rods (10 strains, Group B) and coccoid (1 strain, Group C) were isolated from fish sauce fermentation (nam-pla) in Thailand. The 16S rRNA gene sequence analyses of the representative strains indicated that DS26-2 (Group A), HDS2-5 (Group B), and HRF6 (...

We used double-label liquid scintillation techniques to measure the efficiencies with which eight different-sized zooplankton species ingested four cell types relative to a standard cell type (Chlamydomonas). Efficiency ratios (ERs: clearance rate on cell type X / clearance rate on Chlamydomonas) on the three ultraplankton (<5 mum in diameter) cells (a coccoid bacterium and the algae Synechococ...

A 2-year-old male Pekingese dog was referred to Shiraz University's Veterinary Teaching Hospital for anorexia and depression. The case had no history of surgery. Physical examination revealed no abnormalities except mild depression and fever. Small, coccoid, epicellular bacteria were detected on erythrocytes by microscopic examination of the Giemsa-stained blood smears. Abnormalities noted in t...

Bacteria exhibit a wide variety of morphologies. This could simply be a consequence of an elaboration of bacterial cellular architecture akin to the famous decorative but not structurally essential Spandrels in the Basilica di San Marco in Venice that are a side-effect of an adaptation, rather than a direct product of natural selection. However, it is more likely that particular morphologies fa...

Phocaeicola abscessus strain 7401987(T) is the sole member of the genus Phocaeicola. This bacterium is Gram-negative, non-spore-forming, coccoid to rod-shaped and motile by lophotrichous flagella. It was isolated from a human brain abscess sample. In this work, we describe a set of features of this organism, together with the complete genome sequence and annotation. The 2,530,616 bp long genome...

1. It was demonstrated by pathogenicity and latency tests in mammals and birds that variations exist among a group of viruses, isolated from several sources and producing coccoid elementary bodies resembling those of psittacosis. 2. Active cross immunity tests emphasized these differences and confirmed their significance. 3. On the basis of the present experimental evidence the psittacosis-like...

The biofilm forming abilities of 16 strains representative of 14 of the 16 species comprising the genus Campylobacter were determined on glass, stainless steel, and polystyrene plastic. The formation of biofilms has been suggested as a means by which Campylobacter is able to persist within an inhospitable environment. Of the eight microaerophilic Campylobacter species, including two strains eac...
