Up to now, 24 genera of Nematoda belonging to the Nippostrongylinae (Heligmonellidae) have been reported from New Guinean murid rodents. Nine of these genera have been reviewed in previous works. In the present work, another 11 genera are re-examined on morphological characters mainly corresponding to the synlophe and to a lesser degree to the bursa. This re-examination leads us to recognize three valid genera: Melomystrongylus, Pogonomystrongylus and Nugininema. The remaining genera appear to us insufficiently described or seem to involve more than one taxon; we consider them genera inquirenda. These are: Mawsonema, Montistrongylus, Parvinema, Missimstrongylus, Flannerystrongylus, Helgenema and Paramelomystrongylus. The genus Rodentanema does not belong to the Nippostrongylinae but to the Herpetostrongylidae (Heligmosomoidea). In addition to the three genera recognized herein, nine other genera of Nippostrongylinae are present in New Guinea: Equilophos, Hasanuddinia, Hasegawanema, Hughjonestrongylus, Lesleyella, Macrostrongylus, Nippostrongylus, Parasabanema and Sanduanensis. Several species attributed to the genera Bunomystrongylus, Chisholmia, Odilia and Sabanema are insufficiently described and their generic assignment could not be rectified or ratified. Consequently, the presence of these latter genera in New Guinean rodents remains unconfirmed, until more complete descriptions or illustrations are provided.

Using -rhizobia- interaction networks, we address first the soil invasion success of , and second, we report either -rhizobia partnership should form an isolated module within the symbiosis interaction network. Different indexes were used to determine model invasion success and the network topology. Our results indicated that invasion decreased soil microbial biomass, basal respiration, and enzymatic activities.

The hypothesis that high-altitude mosquitoes spread pathogens over large distances has not been directly tested. Here, we report for the first time that high-altitude windborne mosquitoes are commonly infected with arboviruses, protozoans, and helminths affecting vertebrates and humans, and provide the first description of this pathogen-vector aerial network.

Background: Camels, known as the enduring "ships of the desert," host a complex gut microbiota that plays a crucial role in their survival in extreme environments. However, amidst the fascinating discoveries about the camel gut microbiota, concerns about antibiotic resistance have emerged as a significant global challenge affecting both human and animal populations. Indeed, the continued use of antibiotics in veterinary medicine has led to the widespread emergence of antibiotic-resistant bacteria, which has worsened through gene transfer.

Background: Type 2 diabetes mellitus (T2DM) development is closely linked to microbiota, influenced by geography, ethnicity, gender, and age. While the relationship between oral microbiota and T2DM has been explored, specific microbiota associated with T2DM in the Dai and Han populations remains unclear. This study aims to compare oral microbiota differences and identify keystone species between these populations, both with and without T2DM.

Increasing droughts adversely affect grasslands, diminishing the availability and quality of forages for ruminants. We have recently shown that mixed ensiling of drought-impaired grass (DIG) with sugar beet pulp (SBP) improved the conservation and feed value of silage. The application of silage additives may further improve the ruminal degradability, which may thereby shape the fermentation and microbiome in the rumen when those silages are tested as part of dairy diets.
