Aim: This study was performed to evaluate the effect of systemic tylosin on mastitis rates, cull rates because of mastitis, and quality and quantity of milk production in dairy cows affected with subclinical mastitis. Materials and Methods: A total of 130 California mastitis test (CMT)-positive ...

Bovine mastitis causes great economic loses both to dairy farmers and industry worldwide. Staphylococcus aureus is one of the most prevalent major mastitis pathogens; being antibiotic therapy one of the basis of mastitis control. Susceptibility of 96 Staphylococcus aureus against frequently used...

Dry cow therapy (DCT), an infusion of antibiotics into the mammary gland at the end of lactation, is widely used for the control of intra-mammary infections (IMI) in the dairy cow. However, increased public health concerns about the use of antibiotics, has led to the search for alternatives to the...

This research communication describes the lactating intramammary (IMM) antibiotic formulation most used by Irish dairy farmers at farm level through interviewing 202 dairy farmers. The IMM antibiotic usage data is not easily available to the researcher and farming community. This study determined...

The use of a dry-cow product containing framycetin (Benestermycin) in order to prevent iatrogenic infections by Escherichia coli during a dry period of several weeks was evaluated under German conditions in a trial on 31 cows. The MIC₉₀ of a total of 165 E. coli mastitis isolates was examined. The...

Little is known about the drivers of critically important antibacterial resistance in species with zoonotic potential present on farms (e.g., CTX-M β-lactamase-positive Escherichia coli). We collected samples monthly between January 2017 and December 2018 on 53 dairy farms in South West England,...

Factors affecting bacteriological cure rates (BCR) and new intramammary infections (IMI) during the dry period as well as clinical mastitis (CM) during early lactation were investigated in 414 German Holstein dairy cows receiving dry cow therapy. Cows were treated with either benethamine...

Dry cow therapy is an important part of mastitis control. This therapy typically consists of an antibiotic or antibiotics administered at a single dose by intramammary infusion at dry off to treat or prevent infection by prevalent mastitis pathogens. A combination dry cow therapy consisting of the...

This aim of this study was to evaluate the behaviour of Staphylococcus aureus isolated from bovine mastitis in its subclinical form against the major drug antimicrobial. The study was conducted from the isolation and identification of Stapylococcus aureus from cow milk with subclinical mastitis in...

The objective of the present study was to evaluate intramammary antibiotic treatments used in clinical mastitis cases during lactation. A total of 190 animals from dairy farms in the state of São Paulo were analysed. In vivo evaluation was performed in five dairy farms located in five different...
