The microbial community of a pig slurry on a farm was monitored for 6 months using both molecular and cultural approaches. Sampling was carried out at all the different stages of effluent handling, from the rearing build-up to slurry spreading. Total DNA of each sample was extracted and analyzed by PCR-single-strand conformation polymorphism (SSCP) analysis using primers targeting the 16S rRNA ...
در ابتدا به معرفی بُعد متناهی در نظریهی حلقههای شرکتپذیر rبا توجه به ایدهآلهای دوطرفهی آن میپردازیم. اگر rحلقهای دارای بُعد متناهی روی ایدهآلهای دوطرفه باشد آنگاه ایدهآلهای یکنواخت?u_1،u?_2،…وu_n موجود درr را بدست میآوریم بطوریکه دارای جمع مستقیم و اساسی در r باشند. عدد n مستقل از انتخاب ایدهآلهای یکنواخت u_i است و n را بُعد r مینامیم و با dim r1 نشان میدهیم. سپس فرض میکنیم r ...
Optimal management of indoor air quality in an enclosed swine house, especially in winter, is indispensable for preventing the transmission of infectious respiratory disease to workers and animals. Studies are needed to elucidate the correlation of aerial contaminants and climate factors. It was observed that indoor air contamination in an enclosed pig building was the highest at 2:00--5:00 PM,...
Escherichia coli (n = 1439), isolated from the feces of apparently healthy grow-finish pigs in 20 herds, were tested for susceptibility to 16 antimicrobials. Logistic regression models were developed for each resistance that was observed in more than 5% of the isolates. Each production phase's (suckling, nursery, grow-finish pigs or sows) antimicrobial exposure rate, through feed or water, was ...
Guinea pig gallbladder bile contains chenodeoxycholic acid (62 +/- 5%), ursodeoxycholic acid (8 +/- 5%), and 7-ketolithocholic acid (30 +/- 5%). All three bile acids became labeled to the same specific activity within 30 min after [3H]cholesterol was injected into bile fistula guinea pigs. When a mixture of [3H]ursodeoxycholic acid and [14C]chenodeoxycholic acid was infused into another bile fi...
Swine hepatitis E virus (HEV) was detected by a semiquantitative reverse transcriptase-polymerase chain reaction (RT-PCR) in liver tissue and feces but not in skeletal muscle, pancreas, or heart from pigs experimentally infected intravenously with swine hepatitis E virus (swine HEV). Homogenates of liver tissue and suspensions of feces prepared from swine HEV-infected pigs were inoculated intra...
The association between positive serology and culture detection of Yersinia spp. in individual pigs was determined. Pieces of diaphragm from 370 pig carcasses were collected for serological analysis, and tonsils and feces of the same carcass were collected for bacteriological analysis. Detection of anti-Yersinia antibodies in meat juice samples was done using an indirect enzyme-linked immunosor...
Bacteroides helcogenes Benno et al. 1983 is of interest because of its isolated phylogenetic location and, although it has been found in pig feces and is known to be pathogenic for pigs, occurrence of this bacterium is rare and it does not cause significant damage in intensive animal husbandry. The genome of B. helcogenes P 36-108(T) is already the fifth completed and published type strain geno...
Antagonistic effect of piglet microflora against Clostridium perfringens was studied in germfree mice, to isolate bacterial strains responsible for this colonization resistance. The 1:100 dilution of the feces of a 2 day-old conventional piglet, given per os to germfree mice already harboring C. perfringens, led to the elimination of C. perfringens. From this piglet flora, 8 bacterial strains w...
