Since 2006, 9.2% of Holstein heifers have had at least one breeding with sexed semen, accounting for 6.8% of all heifer breedings; in contrast, 2.4% of all Holstein cows have had at least one sexed semen breeding, or 0.9% of all cow inseminations. The current status of on-farm usage...
A new infectious disease emerged on a ducks farm in Jiangsu Province.The sick ducks showed weakness in legs and diarrhea and pathological findings included necrotic foci in the spleens and hemorrhage in the livers.A virus was isolated from the liver and spleen of a dead duck.The virus isolate...
A United States Midwest swine farm with approximately one thousand 3-month-old pigs experienced an event, in which more than 300 pigs showed neurological signs, like "down and peddling", with approximately 40% mortality. A novel MRV was isolated from the diseased pigs. Sequence and phylogenetic...
(4) Conclusions: Two bacterial strains isolated from the soil on a pig farm are effective in degrading PVK and can be potentially used for bioremediation of PVK antibiotic-contaminated soils. 展开 关键词: Bacillus bacterial isolate biodegradation penicillin pig farm soil ...
An extensively drug-resistant (XDR) Escherichia coli strain 258E was isolated from an anal swab sample of a chicken farm of Anhui province in China. Genomic analyses indicated that the strain 258E harbors an incompatibility group N (IncN) plasmid pEC258-3, which co-produces blaCTX-M-3, bl...
The use of antimicrobial agents in the modern farm industry has created a reservoir of resistant bacteria in food animals. Foods of animal origin are often... FJ Angulo,Section Editor - 《Clinical Infectious Diseases An Official Publication of the Infectious Diseases Society of America》 被引量:...
The presence of virulence genes and integrons was determined in 81 strains of Aeromonas veronii isolated from farm-raised catfish. Polymerase chain reaction (PCR) protocols were used to determine the presence of genes for cytotoxic enterotoxin ( act), aerolysin ( aerA), two cytotonic enterotoxins...
The udder and teat evaluation for mastitis is not usual in most of the farms (70.7%). The frequency of this practice could prove to be positive, as the mastitis are of high damage to animal welfare and farm income – cost of treatments, slaughter, lesser lamb growth and increased mor...
Phages were isolated from waste water from local dairy farm. Phage isolates were determined by their ability to form plaques, specificity, morphology, and effectiveness of bacteriolysis. In this study, 3 phages (FSb, FSs, and FSk) were isolated to replicate S. aureus isolates as a potential ...
Plant derived proteins have been increasingly used as an alternative to fishmeal in aquafeeds [7, 75] but often exhibit deleterious effects on the health and performance of fish [12]. Among those, soybean protein represents a major source of protein for animal nutrition but is particularly challe...
