Metrics details. Mycobacterium spp. The presence of these opportunistic, pathogenic bacteria in bovine milk has emerged as a public-health concern, especially among individuals who consume raw milk and related dairy products. To address this concern, the Brazilian control and eradication program focusing on bovine tuberculosis, was established in However, bovine tuberculosis continues to afflict approximately 1,3 percent of the cattle in Brazil.

Milk spoilage is caused by the presence of proteolytic enzymes produced by Pseudomonas spp. The aim of this study was to identify Pseudomonas spp. Pseudomonas spp. The proteolytic properties of Pseudomonas spp. A total isolates from all 87 samples were confirmed as Pseudomonas , and were identified as belonging to 14 Pseudomonas species.

Laboratory Methods in Microbiology

Laboratory Methods in Microbiology is a laboratory manual based on the experience of the authors over several years in devising and organizing practical classes in microbiology to meet the requirements of students following courses in microbiology at the West of Scotland Agricultural College. The primary object of the manual is to provide a laboratory handbook for use by students following food science, dairying, agriculture and allied courses to degree and diploma level, in addition to being of value to students reading microbiology or general bacteriology. It is hoped that laboratory workers in the food manufacturing and dairying industries will find the book useful in the microbiological aspects of quality control and production development. The book is organized into two parts. Part I is concerned with basic methods in microbiology and would normally form the basis of a first year course. Abbreviated recipes and formulations for a number of typical media and reagents are included where appropriate, so that the principles involved are more readily apparent.

Isolation of Mycobacterium spp. Isolamento de Mycobacterium spp. This study was performed considering the public health hazards related to the elimination of mycobacteria through milk of dairy cows suspected or positive for tuberculosis presenting no clinical alterations. A total of milk samples from 52 animals, positive or suspected for tuberculosis, according to Stormont's test, were analysed to detect Mycobacterium spp. The genus of each observed colony was initially confirmed by Ziehl-Neelsen and auramin staining methods. According to thin layer chromatography, time and temperature growth characteristics and colonies aspects, the 19 animals eliminated: M. According to World Health Organization, Latin America and Caribean countries present a million bovine herd, from which only 80 million can be found in countries where the prevalence of animal tuberculosis is considered low or even nule.

Isolation and identification of mycobacteria from livestock specimens and milk obtained in Brazil. The prevalence of Mycobacterium bovis and other mycobacterial species in livestock specimens and milk was evaluated. An emphasis was placed upon the distribution of these organisms in milk that is readily available to the public that was either untreated, pasteurized, or treated using ultra high temperature. Identification was made by classical biochemical tests, thin layer chromatography of mycolic acids and polymerase chain reaction-restriction fragment length polymorphism PCR-RFLP analysis. Mycobacteria were isolated from 15 Eleven isolates were identified as M.
