Discussion

Mastitis is the inflammation of parenchyma ofmammarygland

characterized by range of physical and chemical changes inmilk and pathological changes in glandular tissues (Radostitis et

al., 2009).

Etiology

Contagious pathogens: Staphylococcus aureus, Streptococcus

agalactiae

Environmental Pathogens: Coliforms include E.coli, Klebsiella,

Enterobacter spp.

Opportunistic pathogens: Coagulase negative staphylococci

Uncommon Pathogens: Mycobacterium bovis,Fungi and Yeasts.

Epidemiology

Environmental pathogens are from environment and induce

mastitis between milking.

Contagious pathogens are transmitted at time of milking.

Risk Factors

Animal risk factors: Prevalence of infection increases with

age. Most new infections occur in dry period and in early

lactation. High producing cows are more susceptible.

Environmental risk factors: Poor quality management of

housing and bedding increases infection rate.

Pathogen risk factors: virulence factors, susceptibilty to anti

microbial agents

Economics: Loss of milk production, costs of treatment and

early culling

Pathogenesis

Invasion phase

Entry of Pathogen into Teat Canal

Invasion of mammary Tissue and Stabilisation in Teat Canal

Infection Stage (multiplication and extension into mammary tissues)

{Production of Endotoxin

e.g. E.Coli

Development of SystemicRXN

Exotoxin and Cellular components

Chemotaxis of Leucocytes to

inflammatory cells

Inflammation stage

Damage to mammary tissue

Swelling and increased temperature in

acute cases12

Control & Prophylaxis

Dry Cow Therapy: Vet-o-Max Long acting ointment 1 tube Intrammary eachquarter SD

Antiseptic Washing: 5% chlorhexidine solution

Kohrosolin TH 1.5%

Post Dipping BID

Milking Hygiene: Positive animal should be milked last.

Milker should wash their hand with detergent.

Do not allow animal to sit for 30 minutes after milking.

VaccinationMASTIVACSig: 5 ml IM 1 wk interval 3 injection prior to parturition

5 ml IM 3 days interval 2 injection
