Further studies on the evaluation of "Valsyn-Gel" were carried out, using both sterile and nonsterile preparations of this drug and comparing it with a drug of choice currently used in mastitis control. The object of the study was to obtain a clearer idea of the time-lapse between the treatment of a quarter until organisms showed again, by taking a series of samples of each treated quarter obtained consecutively at 3-day intervals up to 21 days posttreatment. Results showed that the therapeutic efficiency of the nonsterile product ranged from 86.4 percent 3 days after treatment to 63.6 percent 21 days after treatment. With the sterile product the efficiency ranged from 72.7 to 50.0 percent. The drug of choice, a chlortetracycline ointment, showed a higher efficiency than either of the two other products as evaluated. Nevertheless, it seems apparent that the preparations had a high therapeutic value for the first 9 to 12 days following treatment.

Teat disinfection in dairy herds is an important part of mastitis control, both to reduce infection pressure from the environment and to reduce risk of transmission of infection between cows. Despite much focus on mastitis as an endemic disease, clinical and subclinical mastitis remains an issue for many UK herds, often leading to a perception that changing the teat disinfection product may provide quick solutions. This article summarises the types of products available for both pre- and post-milking teat disinfection, the aim of both types of teat disinfectant and how they may be applied.

AbstractSubclinical mastitis is an asymptomatic udder infection distributed worldwide with enormous losses in the dairy industry. The study’s objective was to determine the presence of this pathological condition in small dairy farms in the R. of N. Macedonia and to identify the most common associated bacteria. Milk samples were obtained from 96 dairy cows (378 udder quarters) in seven dairy farms, in 3 consecutive samplings 24–72 hours apart. The samples were cultured on routine bacteriological growth media and incubated for 24–48 hours. The isolates were identified by AximaiD Plus MALDITOF MS Platform. Subclinical mastitis was found in 49 animals (51%) and 104 infected quarters (27%). The most frequent isolated bacteria on cow level were Streptococcus uberis (19.4%), Staphylococcus haemolyticus (13.4%), Staphylococcus aureus (7.4%) and Staphylococcu ssimulans (7.4%). On quarter level, the most isolated pathogen was Streptococcus uberis (35.6%) followed by Staphylococcu shaemolyticus and Staphylococcus aureus (10.3% and 9.2% respectively). Subclinical mastitis was found to be highly present in the selected small dairy farms. The most prevalent bacteria identified in the dairy farms (Streptococcus uberis, Staphylococcus aureus and coagulase–negative staphylococci) indicate that poor management and udder health practices, inadequate milking procedures and lack of mastitis control strategies greatly contribute to occurrence and persistence of subclinical mastitis.

Prevalence of subclinical mastitis along with the etiological agents and their antimicrobial susceptibility were studied around the city of Dhaka, the capital of Bangladesh. Milk samples from 30 apparently healthy buffaloes were subjected to microbiological examinations while subclinical mastitis was diagnosed based on California Mastitis Test (CTM). Seventy percent of the buffaloes examined were positive for subclinical mastitis. A total of 42 isolates of 5 different species were identified. Among them, Staphylococcus spp. was the most frequently identified bacterial species accounting for 50% of all the isolates, followed by E.coli (28.57%), Enterobacter (14.29%), Bacillus spp. (4.76%) and Proteus spp. (2.38%). Highest resistance was found against amoxicillin (21.43%) where chloramphenicol and ciprofloxac in proved to be a more successful antimicrobial agent, resistance against which wasonly 4.76%. Results from the present study suggest that contagious mastitis controlpractice along with good personal hygiene practice is required for mastitis control in the area.Bangladesh J Microbiol, Volume 30, Number 1-2,June-Dec 2013, pp 1-5

SummaryThe udder health of a research herd of between 160 and 220 Friesian cows run on a commercial basis has been monitored closely, including detailed bacteriological study, over 5 years. The five point mastitis control plan had been in use for several years prior to this study and was continued with minor alterations to the management of the plan, more detailed bacteriological monitoring and increased encouragement to apply it. It has proved possible to make a substantial improvement in the udder health of the herd. The percentage of infected cows fell from 21·9 to 12·0 and the percentage of infected quarters from 7·3 to 3·3. The main benefit has been a drastic reduction in the rate of clinical and subclinical mastitis caused by coagulase-positive staphylococci. However the total incidence of clinical mastitis did not change substantially, averaging around 30 cases/100 cows per year. This was largely because environmental mastitis organisms were responsible for 65 % of all clinical cases. The results showed marked differences in the patterns of infection due to the environmental mastitis pathogens, Gram-negative bacteria and aesculin-hydrolysing streptococci, suggesting different mechanisms of invasion of the gland.

Little information is available regarding the molecular epidemiology of Staphylococcus aureus–induced mastitis in dairy sheep. In this study, 4 different typing techniques were compared in typing 26 S. aureus isolates, predominantly from cases of subclinical mastitis in dairy ewes. The 4 techniques were pulsed-field gel electrophoresis (PFGE), restriction fragment length polymorphism (RFLP) on 2 genes (coagulase and clumping factor B), randomly amplified polymorphic DNA–polymerase chain reaction (PCR) (RAPD-PCR), and multilocus sequence typing (MLST). On the basis of discriminatory power as the key parameter of typing systems, MLST and PFGE were found to be the most powerful techniques. The MLST and PFGE could contribute to epidemiological surveillance and evaluation of mastitis control programs, by documenting prevalence and dissemination of endemic clones in infected populations. The results of this study show that a single clone of S. aureus is widely distributed in infected ewe mammary glands.

Antibiotics are nowadays used and abused worldwide in common veterinary practice to treat diseases, prevent infections, and promote animal’s growth. Drug resistance occurrence is a relevant phenomenon that can inactivate the antibiotic. Moreover, antibiotics used for animals are also found in milk and it poses serious health risks to humans. Another negative effect is related to milk processors since antibiotics cause detrimental effects on cheese and yogurt starter bacteria. Given its consumption as both beverage and derivatives, milk is one of the most regulated products in food industry. Nowadays several commercial tests are available to investigate antibiotics in milk, but they generally provide a qualitative result, require bulky procedure, and are time consuming. In this paper, we investigate the use of a chromogenic cephalosporin to quantify the concentration of cloxacillin—aβ-lactam difficult to be detected by using “cowside” screenings which is the drug of choice in the method of mastitis control. The proposed measurement method and prototype have been demonstrated to be able to detect cloxacillin in milk at concentrations lower than the MRL set by the European Commission. Moreover, they are also able to detect the illegal practice of usingβ-lactamase to degradeβ-lactams in milk.

Teat Dipping

Subclinical mastitis has a higher prevalence than clinical mastitis in many small farmers in Bogor city, and it could reach more than 80 percent. However, the application of teat-dipping could help small farms to control subclinical mastitis prevalence. The objective of this study was to measure the cost of teat-dipping application as subclinical mastitis control in small dairy farms. The partial budget was employed based on the experimental data collected in small dairy farms in Bogor. A number of cows were the basis of simulation for the mean of milk value and the application cost. The findings show an incentive for farmers to apply teat dipping in their farms. The incentive of teat dipping application could be improved to prevent sub-clinical mastitis infection and increase milk production.
