“…It is difficult to assert that the microbiota data of this study was representative of Jersey cow milk, because milk microbiota can be altered by environmental factors including farm management and season. However, the finding that the relative abundance of Pseudomonadaceae was high compared to that reported for Holstein milk (Nguyen et al., 2019; Wu et al., 2019) was noteworthy. Pseudomonas spp.…”

This numerical increase of Lactobacillaceae from individual cow milk to bulk tank milk might be due to an unusual management of bulk tank milk when the Jul samples were collected.…”

Milk is an ideal environment for the growth of many microorganisms due to its high nutritional content. A lot of species, including both desirable and undesirable ones, are detected in raw milk, and thus the milk microbiota may affect the quality and safety of dairy products (Quigley et al., 2013). Some bacteria in milk, including members of Lactococcus spp., Lactobacillus spp., Streptococcus spp., Propionibacterium spp., and Leuconostoc spp. can exert a beneficial role in altering the taste, appearance, and texture of milk and dairy products (Quigley et al., 2013). Meanwhile, several psychrotrophic bacteria, e.g. Pseudomonas spp., Bacillus spp., and Acinetobacter spp., have the ability to grow at low temperatures and become a major cause of milk spoilage, persisting and proliferating during cold storage and producing proteases and lipases (Meer, Baker, Bodyfelt, & Griffiths, 1991; Vithanage et al., 2016). Proteases may reduce the nutrient and economic value of milk by the hydrolysis of casein during milk processing, and lipases can convert lipids into free fatty acids, resulting in unexpected flavor and altering organoleptic properties (Hantsis-Zacharov & Halpern, 2007). Purebred Holsteins have been the major breed in dairy farming because of their overwhelming productivity compared with other breeds. The high milk yield of Holsteins, however, often forces the cows to encounter a serious negative energy balance when they enter lactation after parturition. The state of negative energy balance may increase the number of services per pregnancy and

House flies (Musca domestica) are widespread, synanthropic filth flies commonly found on decaying matter, garbage, and feces as well as human food. They have been shown to vector microbes, including clinically relevant pathogens. Previous studies have demonstrated that house flies carry a complex and variable prokaryotic microbiota, but the main drivers underlying this variability and the influence of habitat on the microbiota remain understudied. Moreover, the differences between the external and internal microbiota and the eukaryotic components have not been examined. To obtain a comprehensive view of the fly microbiota and its environmental drivers, we sampled over 400 flies from two geographically distinct countries (Belgium and Rwanda) and three different environments—farms, homes, and hospitals. Both the internal as well as external microbiota of the house flies were studied, using amplicon sequencing targeting both bacteria and fungi. Results show that the house fly’s internal bacterial community is very diverse yet relatively consistent across geographic location and habitat, dominated by genera Staphylococcus and Weissella. The external bacterial community, however, varies with geographic location and habitat. The fly fungal microbiota carries a distinct signature correlating with the country of sampling, with order Capnodiales and genus Wallemia dominating Belgian flies and genus Cladosporium dominating Rwandan fly samples. Together, our results reveal an intricate country-specific pattern for fungal communities, a relatively stable internal bacterial microbiota and a variable external bacterial microbiota that depends on geographical location and habitat. These findings suggest that vectoring of a wide spectrum of environmental microbes occurs principally through the external fly body surface, while the internal microbiome is likely more limited by fly physiology.

“…The association of Dothideomycetes, including Pleosporales, and Tremellomycetes with milk from organic farms is surprising and unknown, since fungi belonging to these classes often include plant pathogens that grow on wood debris or decaying leaves, yet their presence have been reported in the environment of dairy farms (Mbareche et al, 2018) and in shelves used for ripening of cheese (Guzzon et al, 2017). Airborne dust microbiota and housing conditions, such as bedding, have been described to affect milk microbiota composition, because the teats of cows contact directly with the bedding material when the cows are resting (Nguyen et al, 2019;Wu et al, 2019) and the teat microbiota is a known source of contamination of the milk microbiota (Verdier-Metz et al, 2009;Doyle et al, 2017). Perhaps the reported fungi in this study occur more commonly within the environment of organic farms in particular substrates, but further research is needed to identify the source of these fungi and to evaluate their importance in the context of dairy farms.…”

Microbiota in Dung and Milk Differ Between Organic and Conventional Dairy Farms

et al. 2020

Organic farming is increasingly promoted as a means to reduce the environmental impact of artificial fertilizers, pesticides, herbicides, and antibiotics in conventional dairy systems. These factors potentially affect the microbial communities of the production stages (soil, silage, dung, and milk) of the entire farm cycle. However, understanding whether the microbiota representative of different production stages reflects different agricultural practices-such as conventional versus organic farming-is unknown. Furthermore, the translocation of the microbial community across production stages is scarcely studied. We sequenced the microbial communities of soil, silage, dung, and milk samples from organic and conventional dairy farms in the Netherlands. We found that community structure of soil fungi and bacteria significantly differed among soil types, but not between organic versus conventional farming systems. The microbial communities of silage also did not differ among conventional and organic systems. Nevertheless, the dung microbiota of cows and the fungal communities in the milk were significantly structured by agricultural practice. We conclude that, while the production stages of dairy farms seem to be disconnected in terms of microbial transfer, certain practices specific for each agricultural system, such as the content of diet and the use of antibiotics, are potential drivers of shifts in the cow's microbiota, including the milk produced. This may reflect differences in farm animal health and quality of dairy products depending on farming practices.
