100
Usually cure in few days. Most infections occur before 60 days into a lactation
What is Escherichia coli (E.coli)
100
The most common contagious pathogen in dairy herds ,presenting low cure rates when treated
What is Staph aureus
100
The use of these is extremely important when dealing with contagious pathogens inside the parlor during milking time
What is use of gloves
100
Should be kept for 30 sec to decrease the load of bacteria on teat surface
What is "Pre dip"
100
Percentage of alveolar milk in cows
What is "80%"
200
Important period for environmental pathogens
What is Dry Period
200
Colonizes secretory tissue
What is Staph aureus
200
Many are resistant to germicides in teat dip and antibiotics in dry therapy
What is environmental organisms
200
During this time appearance of milk is checked for any milk abnormality
What is "stripping"
200
During this time check udder hygiene, look for inflammation signs and milk apperance
What is "Strip"
300
Known as unusual or emergent pathogen is found in farms with collection of stagnant water
What is Prototheca
300
The use of dry cow treatment (antibiotic) has helped decrease the prevalence of this contagious pathogen.
What is Strept agalactiae
300
Special attention should be placed on milking time for controlling this group
What is Contagious pathogens
300
To milk all quarters evenly
What is "Proper unit alignment"
300
It can be more difficult to control since many organisms can be resistent to germicides in teat dip
What is "Environmental pathogens"
400
Rate for cure using antibiotic therapy during lactation
What is 50% cure rate
400
With prevalence of 3.2% in US BTM (USDA 2007), this contagious organism can occur even in well managed herds.
What is Mycoplasma
400
Important procedure to identifywhat type of organism is causing the problem
What is "Aseptic collection of milk samples"
400
Development of mastitis is proportional to the number of bacteria present on the teat skin. Replace milk film.
What is "Post Dip"
400
Milking practices as use of gloves, individual towels and milking order are measures important for control of this group of organisms.
What is "Contagious Pathogens"
500
Economically important since can be one of the primary cause of clinical mastitis in low SCC herds
What is Strept uberis
500
Primary reservoir is infected glands. Do not live free in the environment
What is Strep agalactiae
500
will be depending on the cleanliness of the bedding
What is "Teat end exposure"
500
Time from first stimulation to unit attachment that will provide good milk let down
What is "lag time between 90-180 seconds"
500
Fundamental principle of mastitis control
What is "reduce exposure and maximize cow's defense mechanism"
