psychrophile spoilers dominate the bacterial microbiome in musculature samples of slaughter pigs.the aim of this study was to disentangle the microbial diversity on porcine musculature. the hypervariable v1-v2 region of the 16s rrna gene was amplified from dna samples of clinically healthy slaughter pigs (n=8). pyrosequencing yielded 37,000 quality-controlled reads and a diverse microbiome with 54-159 otus per sample was detected. interestingly, 6 out of 8 samples were strongly dominated by 1-2 highly abundant otus (best hits of highly abundant otus: serratia proteamaculans, pseudomonas syr ...201626943946
aeromonas australiensis sp. nov., isolated from irrigation water.a gram-negative, facultatively anaerobic bacillus, designated strain 266(t), was isolated from an irrigation water system in the south-west of western australia. analysis of the 16s rrna gene sequence confirmed that strain 266(t) belonged to the genus aeromonas, with the nearest species being aeromonas fluvialis (99.6% similarity to the type strain, with 6 nucleotide differences) followed by aeromonas veronii and aeromonas allosaccharophila (both 99.5%). analysis of gyrb and rpod sequences sugge ...201323159749
isolation and characterization of acyl homoserine lactone-producing bacteria during an urban river biofilm formation.the presence and diversity of acyl homoserine lactone (ahl)-producers in an urban river biofilm were investigated during 60-day biofilm formation. ahl biosensors detected the presence of ahl-producers in 1-60-day river biofilms. screening for ahl-producers resulted in 17 aeromonas spp., 3 pseudomonas spp., 3 ensifer spp., and 1 acinetobacter sp. among these isolates, six of them were closely related to acinetobacter tjernbergiae, aeromonas allosaccharophila, aeromonas aquariorum, aeromonas janda ...201223090571
cellular changes in the toad urinary bladder in response to metabolic acidosis.the urinary bladder of bufo marinus excretes h+ and nh+4, and the h+ excretion is increased when the animal is placed in metabolic acidosis. the mitochondria-rich (mr) cells mediate the h+ excretion by the bladder. the purpose of this study was to determine if there is a change in mr cells of the bladder during metabolic acidosis. bladders from normal toads and from toads that had been placed in metabolic acidosis were used. the bladders were mounted between plastic chambers and h+ excretion mea ...199996269
aeromonas fluvialis sp. nov., isolated from a spanish river.a gram-stain-negative, facultatively anaerobic bacterial strain, designated 717(t), was isolated from a water sample collected from the muga river, girona, north-east spain. preliminary analysis of the 16s rrna gene sequence showed that this strain belonged to the genus aeromonas, the nearest species being aeromonas veronii (99.5 % similarity, with seven different nucleotides). a polyphasic study based on a multilocus phylogenetic analysis of five housekeeping genes (gyrb, rpod, reca, dnaj and g ...201019648345
use of the novel phylogenetic marker dnaj and dna-dna hybridization to clarify interrelationships within the genus aeromonas.the interrelationships of 27 aeromonas strains were investigated using dnaj sequences and dna-dna hybridization. dnaj sequence similarities showed a stronger relationship with dna-dna relatedness values than did 16s rrna gene sequence similarities. additionally, dnaj sequence analysis, with interspecies divergence over 5.2 % in most cases, gave better resolution than 16s rrna gene sequences for the differentiation of strains at the species level. relationships among aeromonas species were theref ...200717551035
phylogenetic analysis of the genus aeromonas based on two housekeeping genes.the phylogenetic relationships of all known species of the genus aeromonas, and especially aeromonas bestiarum and aeromonas salmonicida, were investigated on 70 strains using the rpod sequence, which encodes the sigma70 factor. this analysis was complemented with the sequence of gyrb, which has already proven useful for determining the phylogenetic relationships in the genus. nucleotide sequences of rpod and gyrb showed that both genes had similar substitution rates (< 2 %) and a similar number ...200415388703
new dna-dna hybridization and phenotypic data on the species aeromonas ichthiosmia and aeromonas allosaccharophila: a. ichthiosmia schubert et al. 1990 is a later synonym of a. veronii hickman-brenner et al. 1987.previously, a dna fingerprinting study based on amplified fragment length polymorphism (aflp) analysis has revealed a possible genotypic resemblance of the species aeromonas ichthiosmia and aeromonas allosaccharophila to aeromonas veronii (huys et al., int. j. syst. bacteriol. 46, 572-580 [19961). currently, two genotypically indistinguishable biovars are known to exist in the latter species, namely a. veronii biovar sobria and a. veronii biovar veronii. in the current study, new dna-dna hybridi ...200111518320
characterization of virulence, cell surface characteristics and biofilm-forming ability of aeromonas spp. isolates from fish and sea water.members of the genus aeromonas are emerging human pathogens, causing a variety of extra-intestinal, systemic and gastrointestinal infections in both immunocompetent and immunocompromised persons. aeromonas virulence is multifaceted and involves surface-associated molecules, motility, biologically active extracellular products and biofilm formation. aeromonads, isolated from diverse freshwater fish species as well as sea water, were screened for biofilm formation, with varying physicochemical par ...201727425219
role of surgical treatment in pancreatic carcinoma.from 1964 through 1984, we treated 810 patients for carcinoma of the pancreas. in 129 patients pde was possible (16%). up to 1977, we had performed whipple's procedures, while from 1978 through 1982 total pancreatectomy was our principal procedure. since 1983, partial pde again has been the procedure of choice for the potentially curative treatment of pancreatic cancer. comparing the results of both methods (60 partial/64 total), we did not find any advantages of total pancreatectomy. operative ...20123815874
