Abstract

The first occurrence of Prototheca mastitis in Hungary is reported: at routine microbial checking of milk samples collected from mastitic cows 144 Prototheca zopfii infected udders were identified in 20 large scale dairy herds in 1997-99. The incidence of infection, its pathological and clinical consequences, as well as certain epidemiological features of the caused mastitis were studied in 3 affected herds. For this purpose milk samples were taken from 73 lactating cows showing mild, chronic form of mastitis and/or producing elevated somatic cell count (SCC) milk recently. About half of them (n-36) were proved to be infected by alga-strains, which were identified as Prototheca zopfii after PORE (1985) and BLASCHKE-HELLMESSEN et al. (1987). In one dairy herd the alga-infected individuals amounted to 10-15% of the milked population. All Prototheca infected cows had been producing milk with ≥ 1 million SCC/ml for several months and in those also showing clinical symptoms the altered milk-appearance (presence of clots and flakes in slightly watery substance) was the only visible sign of mastitis in most of the cases. Necropsy and histological examination of 3 infected cows confirmed the presence of a progressive interstitial mastitis with alveolar atrophy. Fecal samples taken in the herds contained P. zopfii. Deficient milking hygiene, weaknesses of housing technology and the possible transmission during milking were suspected to be responsible for the relatively high incidence of Prototheca mastitis.
