Lactobacilli from turkeys.
نویسندگان
چکیده
Lactobacilli have been reported as being a predominant bacterial type in the intestinal tract of various warm-blooded animals. For instance, Crecelius and Rettger (1943) found that lactobacilli are the most prevalent bacteria in the intestinal tract of guinea pigs. Shapiro and Sarles (1949) reported that lactobacilli are the most numerous bacteria in most areas of the intestinal tract of chickens, and Harrison and Hansen (1950a) that anaerobic lactobacilli (the Lactobacillus bifidus type) comprise the largest part of the flora of the cecal feces of turkeys. As early as the turn of the century it was known that lactobacilli of this type predominate in the stools of breast-fed infants (Tissier, 1900). Weiss and Rettger (1934) conclude from their experiments that lactobacilli may constitute from 90 to 95 per cent of the fecal flora of breast-fed infants. The grampositive, anaerobic rods isolated from the stools of normal adults by Eggerth (1935) in our opinion were probably lactobacilli. It has been definitely demonstrated by Orla-Jensen et al. (1936) that both Lactobacillus bifidus and Lactobacillus acidophilus may be isolated from the stools of humans, the former being the predominant species among the noncoliform types. These workers also pointed out some important physiological differences between the two species, which not infrequently have been confused in the past. The obligate anaerobe, Lactobacillus bifidus, was discovered to be the most prevalent species of bacteria in the feces of turkeys (Harrison and Hansen, 1950a), but in addition a flora of facultative anaerobic lactobacilli was found. These organisms, although less numerous, were of particular interest because they differed in some respects from species in the literature. It is the purpose of this paper to describe the little known avian facultative anaerobic lactobacilli and to discuss their taxonomy.

Determination of standardized prececal protein digestibility of canola meal in British United Turkeys Big 6 at different ages using multiple linear regression procedure
ABSTRACT- Ninety six 2-week-old British United Turkeys (BUT) Big 6 were assigned to 2 groups (4 replicates of 12 birds each). One basal diet and another one in which 20% canola meal replaced the corn starch in the basal diet were prepared. At 9, 16 and 21 wk of age, four birds from each pen slaughtered for digesta collection. The last two-third segment of the intestine, between the Meckel’s div...
متن کاملDetection and subtyping avian metapneumovirus from turkeys in Iran
Avian metapneumovirus (aMPV) causes diseases like rhinotracheitis in turkeys, swollen head syndrome in chickens and avian rhinotracheitis in other birds. Causing respiratory problems, aMPV adversely affects production and inflicts immense economic losses and mortalities, especially in turkey flocks. In recent years, several serological and molecular studies have been conducted on this virus, es...

Ornithobacterium rhinotracheale (ORT) is a respiratory pathogen which has been isolated throughout the world from numerous bird species. The present study was designed to isolate and characterize the ORT from domestic turkeys, quails and pigeons. For this purpose, 250 samples from each bird species (turkey, quail and pigeon) with or without respiratory signs were tested by taking of tracheal...
