Clinical signs

1-Peracute mastitis:* severe systemic reaction (fever , anorexia , depression)

* painful & hot swelling of the the udder* blood stained milk secretion* recumbancy due to toxamia

2-Acute mastitis* painful , hot swelling of the udder

* change in consistancy of milk , presence of flakes or pus

* swelling of supramammary L.N

3 -Chronic mastitis: * fibrosis & atrophy of the udder

* change in milk in the form of clots4-streptococcal mastitis: ch` by:

* fever * inflammation of the udder

* watery milk5-staphylococcal mastitis: ch` by:

* severe systemic reaction * severe swelling of the udder

* gangrene & sloughing of the affected quarter may occur after 1 week

* poor in its response to antibiotic

6-coliform mastitis: ch` by* more common around calving ch` by peracute form

7-Tuberculous mastitis: → chronic disease , ch` by:* induration of the udder

* enlargement of supramammary L.N* milk contain fine flocules → settle down after milk left

stand → clear amber color8-mycoplasma mastitis: ch`by

* sudden onset* involvement of all quarter

* severe swelling of the udder* milk contain granular deposite (fine sandy material &

flakes) → after milk left stand → turbid whey supernant

* complet cessation of milk secretion

9-pasteurella mastitis: common in sheep , ch` by:* systemic reaction

* acute swelling of the udder* watery milk

* the udder become blue & cold (gangrenous mastitis)

10-Mycotic mastitis: (1 )in case of cryptococcus:

*swelling of udder & supramammary L.N*severe ↓ in milk yield

*section of viscid mucoid gray white secretion (2 )in case of candida

*fever * severe inflammation of udder

*swelling of supremammary L.N *presence of large yellow clots in watery fluid

)3 (in case of aspiragillus:*presence of abcesses in udder surrounded by fibrous

tissue

**D.D: from: 1-physiological edema:

* occur after calving * painless swelling of the udder & edema may extend

along abdomen * normal ch` of milk + blood from 1 quarter

* it disappear within 2-3 days * it responds rapidly to diuretics

2-Bloody milk dut to leptospira*flaccid udder & flappy

*the blood come from all quarter *no inflammation of the udder

*has bloody urine 3-bloody milk due to truma:

* blood only without milk *treatment of trumatic bloody milk:

1-I/ mammary infusion of epinephrine alone or with saline (1 - 2 amp.)

2-I/V injection of Cal-D-Mag → 50-100 cm 3 -I/M injection of Vit.K→ amri K 1 amp. / 70 kg B.wt

4 -cold application

Treatment of mastitis:1. I/M injection of panTerramycin → 1cm/10kg b.wt /24 hr / for 5

successive days or streptopencid → 2 vial /12hr / I.M / 5 days (in case of systemic reaction only)

2. Udder infusion with antibiotic (in mastitis drug – in drug index) N.B :

*It is very necessary to evacuate the quarter before infusion of the drug I/mammary

*make massage for the udder after drug infusion *milk from treated cows must be not used for human consumption

for a period of time (acc,. To the used drug)3. Drying off the chronically affected quarter by produce chemical

mastitis by : -udder infusion of 30-60 ml of silver nitrate solution or

copper sulphate 5 % or 100-300 ml of acriflavin solution 1/500

4- supportive treatment : *I/V injection of glucose 25% → 1-2 liter *I/V injection of Avil → 1 amp./70 kg B.wt *local application of cold fomentation (ice bag) on the

udder(in acute cases)
