Abstract

Two surveys were carried out (during 1988 and 1995) to estimate the prevalence of bovine mastitis in Finland. In 1988, 17111 quarter milk samples were obtained from 4495 cows, and in 1995 the corresponding figures were 10410 and 2648. Antimicrobial susceptibility of mastitis pathogens was studied. Prevalence of mastitis on cow basis decreased from 47.8% in 1988 to 37.8% in 1995. Staphylococci was the largest group of pathogens isolated. The proportion of Staphylococcus aureus decreased and that of coagulase-negative staphylococci (CNS) increased. The proportion of strains resistant to at least one antibacterial drug increased with regard to S. aureus from 36.9% in 1988, to 63.6% in 1995 and with CNS from 26.6% to 49.7%. Most of the increase in antibacterial resistance was due to a higher number of ß-lactamase producing strains. Multiresistance also increased, but it was proportional to the overall increase in resistance. All the predominant mastitis streptococci were susceptible to β-lactams tested.

Sammanfattning

Två undersökningar utfördes (under åren 1988 och 1995) för att beräkna förekomsten av mastit i Finland. År 1988 togs mjölkprov från 17111 juverfjärdedelar av sammanlagt 4495 kor. År 1995 var motsvarande antal 10410 och 2648. Man undersökte mastitpatogenernas känslighet mot antibiotika. Mastit prevalensen minskade från 47.8% 1988 till 37.8% 1995. Stafylokockerna utgjorde den största gruppen av isolerade patogener. Antalet Staphylococcus aureus minskade medan de koagulas-negativa stafylokockerna (CNS) ökade. Stammar som var resistenta mot åtminstone ett antibiotikum ökade med avseende på S. aureus från 36.9% 1988 till 63.6% 1995 och med avseende på CNS från 26.6% till 49.7%. Ökningen i antimikrobiresistens berodde främst på ett högre antal β-lactamasproducerande stammar. Även resistensen mot flera antimikrobiella medel ökade, men motsvarade proportionellt sett den allmänna ökningen av resistens. De främsta mastitstreptokokkerna var känsliga för de β-lactamer som testades.
