48 ÍSLENZKAR LANDBÚNAÐARRANNSÓKNIR Hafa ber í huga, að sjúkdómurinn er smitandi og berst frá einni kýr til ann- arrar, einkum með mjaltavélum, mjalta- klútum og jafnvel með höndum mjaltara. Þá verður einnig að hafa í huga, að júgur- bólga sækir í sama horf og áður, nema fullur skilningur sé á eðli, orsökum og margslungnu orsakasamhengi smitsins — sem einar sér eða fleiri saman stuðla að útbreiðslu júgurbólgunnar og viðhaldi SUMMARY Research of mastitis in Icelandic cows and its treatment. Guðbrandur Hlíðar. Mjólkursamsalan, Reykjavík. Mastitis research was carried out for a period of 10 years, from 1967—1977. During the first 3 years, mastitis frequen- cy was investigated in a small area around Reykjavík, but since 1970 investigations were carried out on the herds of all milk hennar, og ber einkum að leita orsakanna í umhverfi kýrinnar. Þá þætti þarf að finna og bæta úr þeim. Má aldrei slaka á árvekni í því starfi, og gildir það jafnt alla daga ársins. Um sjúkdóma í júgri og spenum kúa hef ég skrifað nokkrar greinar í búnaðarblaðið Frey og gert þeim ýtarleg skil í Vasahand- bók bænda 1972. Vísa ég sérstaklega til þeirrar greinar. producers in the country having endemic mastitis problems. During these 7 years, teat samples were taken from 11,387 cows and mastitis infection was found in 5,415, in 21,660 udeer sections (Infected cows were found to be 48.34% of the observed group, and average udder infections were observed in just below two udder sections per cow.) Resistance tests on found sta- phylococci were carried out for 8 antibio- tics. Approximately 75% of found mastitis infection was caused by Staph. aureus.
