With the aim of isolating and identifying bacteria present in the colostrum of women in the city of Barranquilla, located in the Colombian Caribbean, we carried out a descriptive study on 55 colostrum samples, which were cultured on M17, MRS, and TOS agar and incubated under aerobic and anaerobic conditions. A total of 350 microorganisms were isolated, of which 296 were identified at the genus level by PCR-RFLP with the enzymes HaeIII and RsaI. The online program kodebio.shinyapps.io/RFLP-inator was used for the in-silico identification of the isolates. Seven hypothetical bacterial genera were identified: Staphylococcus, Lactobacillus, Enterococcus, Bifidobacterium, Corynobacterium, Streptococcus, and Leuconostoc, with Staphylococcus, Lactobacillus, and Enterococcus being the most dominant, representing 61.1% of the identified microorganisms. Our results are a starting point for understanding the microbial composition of human colostrum, considering the particular context and environmental conditions of the Colombian Caribbean.
