A selective medium facilitating the isolation and recognition of Bordetella bronchiseptica in pigs

Research in Veterinary Science
I M Smith, A J Baskerville


A medium was developed that in most instances allowed the isolation from pigs of Bordetella (Alcaligenes) bronchiseptica in pure, or virtually pure, culture from such sites as the nasal cavity, which contains many other bacteria. If not suppressed, some of the latter can inhibit, sometimes completely, the growth of the bordetellae on artificial media. Besides being markedly selective, the new medium is simple to prepare, reasonably cheap and practically noninhibitory to B bronchiseptica. This organism produces a distinctive colony that is easily differentiated on morphological grounds from the few other bacteria (such as Alcaligenes faecalis and Pseudomonas spp) which also grow on this medium. Parallel examination of specimens from the nasal cavities of 219 pigs in the field in southern England confirmed that this medium was better than hitherto recommended for the detection of B bronchiseptica. This was particularly true when the organism occurred in small numbers only and/or when bacteria little affected by the inhibitors in the previously recommended media were present in the nasal flora.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.

Cell Atlas of the Human Eye

Constructing a cell atlas of the human eye will require transcriptomic and histologic analysis over the lifespan. This understanding will aid in the study of development and disease. Find the latest research pertaining to the Cell Atlas of the Human Eye here.

Single Cell Chromatin Profiling

Techniques like ATAC-seq and CUT&Tag have the potential to allow single cell profiling of chromatin accessibility, histones, and TFs. This will provide novel insight into cellular heterogeneity and cell states. Discover the latest research on single cell chromatin profiling here.
