Abstract

In this work, through microbiological examinations, the etiology of bovine mastitis in 628 milk samples coming from dairy farms from Paraná, Santa Catarina and Rio Grande do Sul along the year of 2007 were evaluated. Out of this total 1,382 microorganisms were isolated. By taking into account the total of isolations, the following microorganisms and their percentage, respectively were found: Staphylococcus spp. (30.53%), Escherichia coli (21.64%), Streptococcus bovis (17.08%), Streptococcus agalactiae (11.07%), Enterobacter spp. (7.53%), Pseudomonas spp. (4.12%) and others (8.03%). The microorganisms grouped into the others are: Streptococcus spp., Proteus spp., gram negative rods, Shigella spp., Alcaligenes spp., Klebsiella spp., Edwarsiella spp., Citrobacter spp., Serratia spp., Salmonella spp. e Corynebacterium spp. The environmental pathogens predominated among the isolated microorganisms; 33.13% of the cultures presented more than three pathogens, suggesting contamination of the samples; in the mounts of November and December, there was an increase of the samples sent.
