The Infant Oral Microbiome: Developmental Dynamics, Modulating Factors, and Implications for Oral and Systemic Health.

The infant oral microbiome is a complex and dynamic microbial community that undergoes various transformations during human development. From birth, these microorganisms are modulated by factors such as birth type, nutrition, oral hygiene, hormonal changes, and environmental and socioeconomic conditions. These elements interact continuously, shaping the diversity and stability of the oral microbiome and consequently influencing the oral and general health of individuals.

The Probiotic in the Feed of Salmonids: A Strategy to Improve Reproductive Parameters.

This study investigated the effects of dietary supplementation with the probiotic on the reproductive performance and offspring viability of male Atlantic salmon (). A total of 48 mature males were divided into three groups-Group A (control, no probiotic), Group B (60-day supplementation), and Group C (120-day supplementation). The fish were kept in 10 m tanks at a constant temperature of 9 °C under a natural photoperiod and evaluated for multiple reproductive and physiological parameters.

Recent Trends in Food Quality and Authentication: The Role of Omics Technologies in Dairy and Meat Production.

The global demand for animal protein presents significant challenges in the production of nutritionally rich foods, such as milk and meat. Traditionally, the quality of these products is assessed using physicochemical, microbiological, and sensory methods. Although effective, these techniques are constrained by time limiting their widespread application.

Revealing the associated microflora hosted by the globally significant parasite Trichostrongylus colubriformis.

Trichostrongylus colubriformis is a parasitic helminth that primarily infects small ruminants, causing substantial economic losses in the livestock industry. Exploring the microbiome of this helminth might provide insights into the potential influence of its microbial community on the parasite's survival. We characterised the intestinal microbiome of T.

Review: Effect of Experimental Diets on the Microbiome of Productive Animals.

The microorganisms that inhabit the gastrointestinal tract are responsible for multiple chains of reactions that affect their environment and modify the internal metabolism, their study receives the name of microbiome, which has become more relevant in recent years. In the near future, the challenges related to feeding are anticipated to escalate, encompassing the nutritional needs to sustain an overpopulated world. Therefore, it is expected that a better understanding of the interactions between microorganisms within the digestive tract will allow their modulation in order to provide an improvement in the immune system, feed efficiency or the promotion of nutritional characteristics in production animals, among others.

Chromosome-length genome assembly of Teladorsagia circumcincta - a globally important helminth parasite in livestock.

Background: Gastrointestinal (GIT) helminthiasis is a global problem that affects livestock health, especially in small ruminants. One of the major helminth parasites of sheep and goats, Teladorsagia circumcincta, infects the abomasum and causes production losses, reductions in weight gain, diarrhoea and, in some cases, death in young animals. Control strategies have relied heavily on the use of anthelmintic medication but, unfortunately, T.

Contribution of the Immune Response in the Ileum to the Development of Diarrhoea caused by Helminth Infection: Studies with the Sheep Model.

Gastrointestinal helminths are a global health issue, for humans as well as domestic animals. Most studies focus on the tissues that are infected with the parasite, but here we studied the ileum, a tissue that is rarely infected by helminths. We tested whether inflammation in the ileum contributes to the development and severity of diarrhoea, by comparing sheep that are susceptible (n = 4) or resistant (n = 4) to the disease.

Bacterial communities in the gastrointestinal tract segments of helminth-resistant and helminth-susceptible sheep.

Background: Helminth parasitism is a world-wide problem in livestock industries, with major impacts on health, welfare and productivity. The role of the gut microbiota in host-helminth interactions in ruminants has been extensively examined and the present study added to this body of knowledge by assessing the effects of resistance and susceptibility to helminth infection in the gastro-intestinal tract (GIT). Australian Sheep Breeding Values (ASBVs) for faecal egg count (FEC) were used to select the 10 highly helminth-susceptible (High-FEC) and 10 highly helminth-resistant (Low-FEC) sheep.

Investigating the development of diarrhoea through gene expression analysis in sheep genetically resistant to gastrointestinal helminth infection.

Gastrointestinal helminths infect livestock causing health problems including severe diarrhoea. To explore the underlying biological mechanisms relating to development and control of diarrhoea, we compared 4 sheep that were susceptible to development of diarrhoea with 4 sheep that were diarrhoea-resistant. Transcriptomes in the tissues where the parasites were located were analyzed using RNASeq.
