| factors affecting the incidence and anti-salmonella activity of the anaerobic caecal flora of the young chick. | thirty-two different types of anaerobic bacteria isolated from chickens have been tested for anti-salmonella activity in vitro. under the conditions of the test only bacteroides hypermegas and a bifidobacterium sp. were shown to inhibit the salmonellas and this was attributed to the production of volatile fatty acids (vfa's) coupled with a low ph. when these organisms were tested in newly hatched chicks no inhibition of s. typhimurium occurred. possible explanations for this observation are cons ... | 1979 | 34658 |

| genus megamonas should be placed in the lineage of firmicutes; clostridia; clostridiales; 'acidaminococcaceae'; megamonas. | megamonas hypermegale is the sole species of the genus megamonas included in the list of prokaryotic names with standing in nomenclature and in the databases of ddbj, ebi/embl and ncbi/genbank it is placed in the lineage of bacteroidetes; bacteroidetes (class); 'bacteroidales'; bacteroidaceae; megamonas. phylogenetic analysis based on comparative 16s rrna gene sequencing showed that this species clustered with species of the family 'acidaminococcaceae' but not with those of the bacteroidaceae. t ... | 2007 | 17625216 |
| sutterella parvirubra sp. nov. and megamonas funiformis sp. nov., isolated from human faeces. | three strains of anaerobic, non-spore-forming, gram-negative coccobacilli (yit 11816t, yit 11817 and yit 11818) were isolated from human faeces. on the basis of 16s rrna gene sequence similarity, these strains were shown to belong to the family alcaligenaceae and to be related to the type strain of sutterella stercoricanis (94.9 %) and to sutterella wadsworthensis wal 7877 (94.3 %); the similarity to strains of any other species with a validly published name within the family alcaligenaceae was ... | 2008 | 18398204 |
| megamonas rupellensis sp. nov., an anaerobe isolated from the caecum of a duck. | we report here the identification, characterization and culture of a gram-negative to gram-variable, rod-shaped, non-spore-forming anaerobic bacterium (strain fm1025(t)) isolated from the caecum of a duck. phylogenetic analysis based on comparative 16s rrna gene sequencing showed that this strain clustered with species of the family 'acidaminococcaceae', with 94.9 % similarity to megamonas hypermegale dsm 1672(t) and less than 91 % similarity with type strains of pectinatus species. sequence sim ... | 2008 | 19060083 |
| antibiotic manipulation of intestinal microbiota to identify microbes associated with campylobacter jejuni exclusion in poultry. | the ability of various subsets of poultry intestinal microbiota to protect turkeys from colonization by campylobacter jejuni was investigated. community subsets were generated in vivo by inoculation of day-old poults with the cecal contents of a campylobacter-free adult turkey, followed by treatment with one antimicrobial, either virginiamycin, enrofloxacin, neomycin, or vancomycin. the c. jejuni loads of the enrofloxacin-, neomycin-, and vancomycin-derived communities were decreased by 1 log, 2 ... | 2010 | 20952640 |
| effects of dietary fiber on cecal short-chain fatty acid and cecal microbiota of broiler and laying-hen chicks. | this experiment was conducted to evaluate the effects of feeding dietary fiber on cecal short-chain fatty acid (scfa) concentration and cecal microbiota of broiler and laying-hen chicks. the lower fiber diet was based on corn-soybean meal (sbm) and the higher fiber diet was formulated using corn-sbm-dried distillers grains with solubles (ddgs) and wheat bran to contain 60.0 g/kg of both ddgs and wheat bran from 1 to 12 d and 80.0 g/kg of both ddgs and wheat bran from 13 to 21 d. diets were formu ... | 2015 | 26316341 |
