Bovine mastitis is considered the main disease of dairy herds in the world, causing the greatest economic losses to the dairy sector. In Brazil, production losses caused by mastitis are estimated between 12 and 15%, accounting to more than three billion liters of milk per year. In addition, mastitis poses risks to public health, due to the possibility of contamination of milk with antibiotic residues or with microorganisms and their toxins. The high frequency of mastitis pathogens resistant to t

The presence of enterotoxigenic Staphylococcus and its enterotoxins in milk and dairy products is a concern for industry and government agencies responsible for public health. S. aureus is the species most often associated with outbreaks or cases of staphylococcal food poisoning. As this microorganism is an important pathogen of mastitis in cattle, the udder of the infected animal is one of the main sources of contamination of raw milk. Other species of Staphylococcus hav

Due to the importance of leguminous vegetables for human diets, the year of 2016 was declared by FAO the International Year of Pulses. Pulses are well appreciated in Brazil, and are consumed either fresh or in the form of processed products. Internal consumption has required frequent imports of such pulses; for peas and chickpeas alone, they represented US$ 14 million a year. The domestic market tends to expand due to the constant association of such foods with a series of attributes of high foo

The technology for gene editing based on the CRISPR / Cas9 system (Clustered Regularly-Interspaced Short Palindromic Repeats associated to Cas9 endonuclease) consists of an endonuclease (Cas9) guided by RNA (guide RNA - sgRNA), which is capable of editing the genome with accuracy. This system enables the inactivation of genes through cleavage followed by repairing the strands by non-homologous end joining (NHEJ) leading to the knockout of the expression, which results extremely useful to prevent

In Brazil, milk production is practiced by more than one million farmers, mostly smallholders, who have in pastures and swards for green chop the most important sources for cattle feeding. Dairy agribusiness plays a significant role in food supply for the domestic market, in the generation of jobs and income for the population and in recent years has also become increasingly important in the Country’s export line. The intensification of animal production systems demands the use of forage species

The soilborne mosaic in wheat is a viral disease whose negative effects on wheat production have become more frequent in several wheat regions in southern Brazil. This disease can reduce productivity by 50% if susceptible cultivars are sown in areas with inoculum and favorable environment conditions. In Brazil, the common mosaic is attributed to Soil-borne wheat mosaic virus (SBWMV) and also to Wheat spindle streak virus (WSSMV), both transmitted by Polymyxa graminis, pla

The genus Cynodon (Star and Bermuda grasses), among the existing grasses as alternatives for pasture exploitation, present advantages such as high productivity and forage quality, response to fertilization, resistance to trampling, good adaptation to different types of soils and climate, good tolerance to humid soils and low temperatures. These factors distinguish the genus Cynodon from others that predominate in tropical conditions and justify its choice as a promising alternati

Heat along with high humidity is one of the causes of impaired milk production and fertility of cattle, especially in the summer or in tropical and semitropical regions. Such problems can be aggravated with the prospect of global warming. In the hottest regions of Brazil there is a preference for crossbred Holstein (H) X zebu (Z), mainly Gir (G) cattle that form the Girolando synthetic breed whose composition is mainly ⅝ GxH. Girolando animals are more tolerant to heat than breeds of European or
