Cattle are affected by a range of infectious agents, including bacteria, fungi, viruses and prions. The diseases caused by these microorganisms frequently have an important effect on production and may, in some cases, cause mortality. Infectious diseases are often diagnosed on the basis of the case history and clinical signs, or following post‐mortem and histopathological examination. Isolation of...
The detection of DNA hybridization is of central importance to the diagnostic and treatment of genetic diseases, for the detection of infectious agents, and for reliable forensic analysis. The technique for the detection of DNA hybridization has attracted many attentions. Many methods for detecting hybridization have been developed, including electrochemical, optical, microgravimetric methods and...
This paper describes the prospects and challenges of cry preservation of tissue and tissue engineered products for their application to tissue repair and regeneration. The various aspects of cry preservation include optimization of cell specific freezing parameters such as cooling rate, type and concentration of cry oprotective agents (CPA), media, treatment methods, warming and thawing for the preservation...
Based on an array of combined metal oxide and conductive polymer gas sensors electronic an odor recognition system is being developed for detection of bacteria types at the early stages of wound infection. It is proved by GC-MS studies that living bacteria that are typical infectious agents in clinical practice can be distinguished from each other by means of a limited set of key volatile products...
This study reports on the efficacy of atmospheric oxygen-argon plasma for bio-decontamination or surface sterilization of infectious agents, such as Bacillus anthracis [Sterne] (Anthrax), MS-2 bacteriophage, and E coli. A 10- second exposure (RF power 77 W, 29.5 mL O2/min, 28 L Ar/min) on the B. a. spores revealed an average post-exposure log reduction (LR) value of 2.7, whereas a 20-second treatment...
During the last decade, label-free optical biosensors have become valuable tools for clinical and military use as well as drug discovery. They are important devices for a range of applications going from detection of infectious agents, toxins, proteins and DNA to investigation of whole cell behaviour. Modern label-free optical biosensors, like the widely utilised surface plasmon resonance (SPR) method,...
In the Northeast United States, marine vertebrates come into contact with each other and with humans through a variety of mechanisms which allow for the transfer of pathogens from one taxa to another. Though there are many ways in which humans come into contact with infectious agents, there is an inadequate understanding of the prevalence of clinical and sub-clinical zoonotic agents in the marine...
