He has coordinated 26 research projects. He currently works in veterinary medicine, with an emphasis on Milk Quality, Nutrition, and Mastitis Control of dairy cows. Furthermore, he served as the Head of the Department of Nutrition and Animal Production, FMVZ-USP, from 2006 to 2008 and from 2016 to 2018, and was the Coordinator of the Graduate Program in Nutrition and Animal Production from 2008 to 2012. He also served as President of the Brazilian Council for Quality Milk (CBQL) from 2009 to 2011. Currently, he is a member of the Editorial Board of the Brazilian Journal of Veterinary Research and Animal Science as the Editor of the Animal Nutrition and Production Area, and the coordinator of the Qualileite Laboratory (www.qualileite.org). Moreover, he also routinely writes for a specialized dairy website (www.milkpoint.com.br). (Source: Lattes Curriculum)

The non-responsible use of antimicrobials (ATM) in human and veterinary medicine and animal production has been associated with increased antimicrobial resistance (AMR) worldwide. In dairy cattle, ATM therapy is the key strategy for treating infectious diseases, but the overuse of antimicrobials has been associated with increased AMR. To address this scientific and technological challenge…
Mastitis control presents significant challenges, but the nature of the disease also offers opportunities for intervention. The challenges associated with antimicrobial resistance, biofilm formation and invasive strains inspired us to test the potential use of an organic polymer to kill antimicrobial resistant and intracellular pathogens. PHMB offers a compelling opportunity in the Mastit…
The general objectives of this proposal are to evaluate: a) etiologic profile and antimicrobial susceptibility of pathogens causing clinical mastitis and to describe the qualitative and quantitative aspects relating to the use of antimicrobials; b) efficiency of on farm culture program, specially on the use of antimicrobials and economic aspects related to expenses incurred for clinical m…
The aim of this study was to evaluate the effect of subclinical intramammary infection (IMI) caused by coagulase-negative staphylococci (CNS) as a group and by specific CNS species on milk yield and composition and somatic cell count (SCC) of dairy cows. Selection of cows with IMI caused by CNS was performed by microbiological cultures of composite samples collected from 1,242 dairy cows …

The irresponsible use of antimicrobials (ATM) in human, veterinary medicine and animal production has been correlated with the antimicrobial resistance (AMR) globally. In this scenario, the rapid and reliable identification of potential pathogens and AMR patterns is extremely important for the responsible use of antimicrobials. Aiming to face this scientific challenge, this proposal is st…
The increase in antimicrobial resistance (AR) is a worldwide concern, which has been partially associated with the overuse of antimicrobials in animal production. In dairy cattle, clinical mastitis (CM) treatment and dry-cow-therapy (DCT) are the main causes of antimicrobial use and, for this reason, the responsible antimicrobial use for these purposes can impact public health. In this se…
Mastitis is an inflammation of the mammary gland, mostly caused by bacteria, and it has two major forms: clinical and subclinical. The monitoring of the severity of clinical cases, which are classified as mild, moderate, or severe, is essential for the control of the disease. S. aureus remains one of the main pathogens causing mastitis and its numerous virulence factors are critical facto…
Bovine mastitis is an inflammation of the mammary glands, which could be caused by multiple etiologies and has difficult control. Mastitis causing pathogens may be of contagious or environmental origin, and the inflammation may manifestates with different degrees of severity, according to the type of the causing pathogen. It's a disease that causes great economic losses in the dairy indu…
Post-milking teat disinfection is a common practice to prevent contagious Mastitis pathogens as Staphylococcus aureus in dairy herds. Previous studies reported the in vitro antimicrobial activity of the polyhexamethylene biguanide (PHMB) polymer against Staphylococcus aureus isolated from Bovine Mastitis cases. The hypothesis of the present study is that Mastitis-causing Staph. aureus pro…

Bovine mastitis is acknowledged as the most impactful disease affecting dairy farming globally. This condition not only imposes considerable economic losses on the dairy industry but also represents a significant threat to public health. It can be classified as either contagious or environmental, with different manifestation forms (subclinical or clinical mastitis) depending on the pathog…
The persistence of mastitis as a prominent challenge in the dairy industry continues to significantly impact both the quantity and quality of milk produced. Recent research highlights the crucial role of non-aureus Staphylococci (NAS) not only in the development but also in the prevention of mastitis, underscoring the urgent need for a deeper analysis of its interactions with conventional…
The increase in antimicrobial resistance (AMR) is a concern worldwide, and has been associated with the overuse of antimicrobials in animal production. In dairy cattle, clinical mastitis (CM) is the main reason for antimicrobial use. Thus, antimicrobial stewardship practices in dairy cattle production will necessarily consider therapy of CM. The ability to predict the risk of clinical and…
The goal of present study is to establish histidine (His) requirements for lactating Holstein dairy cows. To fulfill the objectives of this proposal we shall conduct experiments in order to establish His requirements in lactating dairy cows fed metabolizable protein (MP)-deficient diets or diets supplying MP at or above NRC (2001). These experiments will be Latin square design with 28-d p…
The epidemiology and etiology of mastitis-causing environmental streptococci, especially "other streptococci" and streptococci-like bacteria is not well known. The objectives of this research project will be: (a) to determine at species level the frequency of mastitis-causing pathogens identified phenotypically as "other Streptococcal species" using the technique of matrix-assisted laser …
