Q

What pathogens are involved in summer mastitis complex

vector for transmission?

at risk animals ?

A

D. dysgalactiae and T pyogenes (used for C and s)

vector: hydrotea irritans

dry cows and heifers in summer

Hot, hard, swollen udder with thick purulent secretion
Lameness and systemic illness possible
Mild cases do occur and are only noticed as cow calved down with blind teat end or with a mild case of mastitis from which T. Pyogenes is cultured

Q

black discolouration of teat
damage to teat end+ secondary infection with fusobacterium necrophorum
common

Which teat lesion is this
treatment?

Study These Flashcards
A

black spot
topical abs, teat canula

check milk machine for excess vaccum causing teat end eversion

22
Q

pustular lesions on teat and udder skin
can spread to humans
caused by staphylococcus aureus

Which teat lesion is this
treatment?

Study These Flashcards
A

udder/teat impetigo

PMTD, aseptic udder cream

23
Q

non pigmented skin (white) affected
Which teat lesion is this
treatment?

Study These Flashcards
A

photosensitisation

sunblock, NSAIDs, keep indoors

24
Q

caused by poor teat skin care, worn teat liners, calves suckling

Which teat lesion is this
treatment?

Study These Flashcards
A

chapped teats

emollients, teat canula

change liners every 2500 milkinga

25
caused by excessive vacuum, overmilking, faulty liners, everted teat ends and degrees of keratosis - graded normal, smooth, rough and very rough Which teat lesion is this treatment?
hyperkeratosis
26
what degrees of keratosis increase risk of mastitis
rough or very rough
27
Pedunculated granuloma attached to wall of teat canal, blocking milk flow Which teat lesion is this treatment?
Teat pea removal via hudson spiral / mosquito forcep removal ABs to prevent mastitis
28
usually occurs secondary to trauma, has guarded prognosis as scar tissue may reform treated by inserting small knife and rotating + resting with canula + im antibiotics for 3-5 days Which teat lesion is this treatment?
teat stenosis
29
with blind teats, how should you treat - if no milk: - if milk:
- if no milk: leave as cannot open | - if milk: treat as per stenosis as lesion is in canal
30
should you suture a superficial wound on teat?
no, use tape or glue
31
at what age does LA required to remove supernumerary teat (inherited condition)?
> 2 months ONLY REMOVE IF CERTAIN ITS SUPERNUMERARY
32
does pre milking teat dipping protect against environmental or contagion pathogens?
environmental
33
does post milking teat dipping protect against environmental or contagion pathogens?
contagion
34
4 components of teat dips
disinfectants: iodine/ chlorhexidine/ lactic acid emollients: ianolin, glycerine for skin condition dye sticking agents
35
what is the correct order to milk cows
least likely to be infected to most likely heifers> fresh calvers> high yielder> low yielders> high somatic cell count cows> mastitis cows
36
if staphylococcus aureus is present, what should be done in the parlour wash up routine?
hot wash ( > 60) every milking
37
What are the following housing indexes? CCI SUI SSI
CCI = cow comfort index= no cows correctly in cubical/ no cows in cubicle X100 ``` SUI= stall use time SSI= stall standing time ```
38
what is a bulk tank bactoscan?
count of bacteria in bulk tank milk > 50000 exclused from supermarket until below 50000 for 3 months
39
what is the california mastitis test?
quick milk SCC test
40
interpretation of individual cell counts
* <100,000 cells/ml = no infection likely * 100-200,000 cells/ml = likely one infected quarter with minor pathogen * >200,000 cells.ml = infected quarter with major pathogen * If bulk milk tank >400,000 there is a risk the dairy will not collect the milk
41
treatment options for Strep aureus and uberis during lactation
intramammary cloaxacillin for 6 days tylosin systemic (staph aureus penicillin resistant)
42
bulk milk tank over ? > cells/ml then risk dairy will not accept the milk
400,000
43
which mastitis pathogens are penicillin sensitive
Strep agalactiae and dysgalactiae
44
cow calved last night, this morning is dull off food, unwilling to stand HR 105bpm no rumen turnover bedding is moist painful udder and dehydrated, toxaemia, septicaemia,
toxic mastitis - oft e.coli
45
tx for toxic mastitis?
oxytocin to strip down fluids (if HR > 100bpm) antibiotics systemic IV and local
46
NSAIDs for mastitis
``` Flunixin Ketoprofen Tolfenamic acid meloxicam carprofen ```
47
which NSAID used for mastitis has a milk withhold of 5 days?
Meloxicam
48
which NSAIDs used for mastitis have no milk withold?
ketoprofen and carprofen
49
which NSAIDs used for mastitis have milk withold of 12-48 hours
flunixin
50
which NSAIDs used for mastitis have with hold for fist milking?
tolfenamic acid
