The cause of bluecomb disease in turkeys is unknown. Filtration of infective intestinal contents suggests a viral origin. To date, it has not been possible to isolate the etiologic agent in various cell cultures. The purpose of this work was to characterize as many virus-like entities as were recognizable in intestines of both healthy and bluecomb-infected turkeys. By a comparison of the viral populations it was hoped that some insight might be gained into the cause of this disease. Studies of turkey hemorraghic enteritis by Gross and Moore (Avian Dis. 11: 296-307, 1967) have suggested that a bacteriophage-host cell interaction may bear some causal relationship to that disease.

From 112 marine fishes examined for the presence of lactose-fermenting bacteria, 31 strains were isolated which produced acid and gas in this sugar and 3 which produced acid only.Ten strains belonged to the genus Aerobacter, 8 being Aer. aerogenes and 2 probably varieties of Aer. cloacae. Nine were soil types and the relationship of one was doubtful.Of 24 Escherichia types, 8 were faecal mammalian strains and one was doubtful. These belonged to the species Esch. coli, Esch. communior, Esch. grünthali and Bact. immobilis. One was found in a haddock taken 3 miles offshore; the others were found in fish taken in contaminated waters or near shore.Esch. coli, Esch. communior and Aer. aerogenes are not normal inhabitants of the intestinal tracts of marine fish.

ABSTRACT The ermG gene was first found in the soil bacterium Bacillus sphaericus. More recently, it was found in several human intestinal Bacteroides species. We report here the first finding of ermG genes in gram-positive bacteria isolated from porcine feces and from under-barn manure pits used to store porcine wastes. The porcine ermG sequences were identical to the sequence of the B. sphaericus ermG gene except that six of the seven ermG-containing strains contained an insertion sequence element insertion in the C-terminal end of the gene. The porcine ermG genes were found in three different gram-positive genera, an indication that it is possible that the gene is being spread by horizontal gene transfer. A segment of a Bacteroides conjugative transposon that carries an ermG gene cross-hybridized with DNA from six of the seven porcine isolates, but the restriction patterns in the porcine strains were different from that of the Bacteroides conjugative transposon.

Studies on the elimination of virus in human paralytic poliomyelitis during the first 2 weeks of the disease, revealed the following:— 1. The nasal (not nasopharyngeal) secretions collected from 22 patients on cotton plugs over a period of 3 days and the saliva and oral secretions expectorated during a similar period by 20 patients failed to yield virus. 2. In 10 of the patients whose secretions (nasal, oral, or both) were investigated, virus was isolated from single specimens of the lower intestinal contents. 3. No virus was found in large amounts of urine (up to 200 cc.) obtained from 12 patients, 6 of whom had paralysis of the bladder. 4. In the present tests virus was found 4 times more often in the stools of patients under 8 years of age (64 per cent of 11 cases) than in older individuals (17 per cent of 12 cases). This difference was found to obtain when our data were combined with those which could justifiably be selected from the literature, the total figures indicating that virus has been isolated from 50 per cent of 58 children under 8 years of age and from 12 per cent of 60 older individuals. 5. No support was found for the hypothesis that poliomyelitis virus in the stools originates from swallowed nasal secretions and saliva or oral secretions.

ABSTRACTFifty-one cattle were allocated into five groups varying in time of starvation (0, 17, 24, 41 and 48 h). Most of the loss in fasted live weight, stomach and intestinal contents occurred within 24 h. Weights of water, dry matter and potassium present in the stomach showed a significant decrease in the first 24 h, although the percentage of water in the stomach contents rose slowly over a 48-h period. It is suggested that cattle from pasture need be starved for no more than 24 h to minimize the effect of gut fill for body composition studies.
