Animals were in late lactation and bacteriological analyses including mycoplasmas were made from aseptic milk samples individualy taken from udder halves. The presence of intramammary infection (IMI) was studied in relation to goat parity. Three parity groups were considered: first and second; third, fourth and fifth; and six and greater parities. Prevalence of IMI was 22% of halves and 34% of animals. Most of isolates were Staphylococci (70%). Using the prevalence ratio (PR) and confidence interval (CI), we saw a positive statistical association between subclinical intramammary infection and greater than fifth parity (PR=1.80; 95% CI=1.21, 2.68).  aGoat diseases  aGoats  aMastitis  aCaprino  aFator de risco  aLatent infections  aMastite  aMastite subclinica  aRisck factor1 aCONTRERAS, A.1 aCORRALES, J.
