“…Results obtained on 393 mother-infants dyads of the CHILD cohort support the influence of the body mass index, parity, mode of delivery, and breastfeeding practices (at breast versus pumped) (Moossavi et al, 2019). In bovines, several host-associated factors are likely to influence milk and mammary gland microbiota such as physiological parameters and anatomical characteristics of the teat and genetic traits (Derakhshani et al, 2018a).…”

“…Besides the biases introduced by sampling and methods, several host and environmental factors have been reported to influence milk microbiota composition in human and cows (Figure 1 and Supplementary Table S3). Of note, most factors investigated for human and bovines are not exactly the same and, as expected, are in relation with management practices for cows (see Derakhshani et al, 2018a, for a recent review of factors that potentially influence bovine mammary microbiota). Among host factors affecting milk microbiota, several studies have reported a relation between milk microbiota and mother's health, with special attention to mammary gland infections.…”

“…An overview of studies on milk microbiota clearly points out common taxa between human and cow milk (Supplementary Tables S1-S4 and Figure 2): Staphylococcus, Streptococcus, Pseudomonas, Bifidobacterium, Propionibacterium, Bacteroides, Corynebacterium, and Enterococcus are among the most cited dominant taxa in studies on both human and bovine milk microbiota (Oikonomou et al, 2014;Jiménez et al, 2015;Addis et al, 2016;Boix-Amoròs et al, 2016;Urbaniak et al, 2016;Murphy et al, 2017;Derakhshani et al, 2018a). On the other hand, Metzger et al (2018b) did suggest that the detection of Pseudomonas could be attributed to contamination issues as it was one of the genera they found to be abundant in their negative control samples.…”

“…However, these geographical differences could be due to several factors, such as environment, diet, or even genetics. In bovines, while the influence of "geography" per se has not been studied, milk microbiota was found to be related to the farm environment and management practices (Doyle et al, 2017;Derakhshani et al, 2018a;Frétin et al, 2018;Metzger et al, 2018a). Metzger et al (2018a) reported a relation between the bedding material and the bovine milk microbiota profiles.…”

“…This is also the case for bovine milk. At the time this community is being explored, several questions and sometimes controversies are raised concerning its origin, its role and even its existence (Jost et al, 2015;Addis et al, 2016;Rainard, 2017;Derakhshani et al, 2018a;Metzger et al, 2018b). It thus appeared relevant to us to attempt to describe the research that has already been done on the milk microbiota and what is exactly known.…”

Milk Microbiota: What Are We Exactly Talking About?

The development of powerful sequencing techniques has allowed, albeit with some biases, the identification and inventory of complex microbial communities that inhabit different body sites or body fluids, some of which were previously considered sterile. Notably, milk is now considered to host a complex microbial community with great diversity. Milk microbiota is now well documented in various hosts. Based on the growing literature on this microbial community, we address here the question of what milk microbiota is. We summarize and compare the microbial composition of milk in humans and in ruminants and address the existence of a putative core milk microbiota. We discuss the factors that contribute to shape the milk microbiota or affect its composition, including host and environmental factors as well as methodological factors, such as the sampling and sequencing techniques, which likely introduce distortion in milk microbiota analysis. The roles that milk microbiota are likely to play in the mother and offspring physiology and health are presented together with recent data on the hypothesis of an enteromammary pathway. At last, this fascinating field raises a series of questions, which are listed and commented here and which open new research avenues.
