Detection of mastitis pathogens in raw milk of symptomatic cows
Application note on detection of mastitis pathogens in cows
3 Oct 2019In this application note, Analytik Jena has described a method for detecting different pathogens using its new product qTOWER3. Extraction of bacterial DNA has been a challenge due to diversity of ingredients found in milk, such as fat, sugar and protein. A special extraction kit is usually recommended to optimize extraction of DNA. This application note mentions the Mastit 4C Kit by DNA Diagnostic. Identifying symptomatic cows and isolating them is the only way to prevent pathogen spreading and therefore this method could be a valuable resource in the milk farming industry.

MicrobiologyMicrobiology is the study of microorganisms including protists, prokaryotes, fungi, and, often, viruses. Microorganisms are a useful research tool as genetic vectors and, in immunology, for antibiotic susceptibility testing, cellular biology and genetics. Microorganisms commonly grow readily in incubators with microbial culture media; this can contain chromogenic supplements to differentiate between cell lines. Estimate your culture’s density of microorganisms with colony counters, or screen and select colonies for desirable clones with automated colony pickers. Additionally, equipment is available to monitor environments for the presence of microbes and identify with microbial identification instruments.

Nucleic acids can be detected by labeling with colorimetric, fluorescent or radio labels and using in situ hybridization kits to identify specific sequences. Multiple nucleic acids can be detected and quantified at once using RNA / DNA detection beads or RNA / DNA microarrays.
