This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"Bovine respiratory disease, also known as shipping fever, is a primary cause of morbidity and mortality in feedlots. Although pneumonia-causing bacteria are thought to be located in the nasopharynx, contributions from other parts of the upper respiratory tract remain poorly characterized. A recent study characterized the composition of different respiratory bacterial communities in beef cattle. Researchers sequenced DNA from different respiratory samples collected from 15 healthy feedlot steer calves. They found that microbiota composition differed across sampling locations. The lung was more similar to the nasopharynx than to the oropharynx or any other sampling location. And one metacommunity found in the lung and nasopharynx was dominated by Mycoplasma dispar, a bacterium of potential significance in bovine respiratory microbiota research. Further studies are needed to determine how bovine respiratory disease affects the relationships between different respiratory bacterial communities..."
