Article Abstract

Stream ecosystem health assessments are crucial for the effective management of aquatic ecosystem service functions and the assessment of anthropogenic and climatic impacts on aquatic ecosystems. However, there is still a lack of comprehensive assessment methods based on complete ecosystem structures. This study improved an ecological health assessment system, which consists of 13 indicators based on ecosystem structure. The assessment system was applied to 30 streams on Changbai Mountain. The results showed that the comprehensive index of stream health (ISH) in Changbai Mountain was relatively high, and the ISH increased with the elevation gradient. The dominant factors controlling the ecosystem health level were water pH, water flow, vegetation coverage, total phosphorus (TP), and vegetation diversity index. All these results indicated that the damage caused by excessive deforestation and farmland occupation in recent years has not been fully reversed and that human disturbance from tourism may be the main reason for the low stream health at lower elevations. Our results suggest that the key to future work is to increase quantitative research on disturbance sensitivity and to develop economically viable restoration measures.

Metagenomic sequencing deepened our knowledge about the role of the intestinal microbiota in human health, and several studies with various methodologies explored its dynamics during antibiotic treatments. We compared the impact of four widely used antibiotics on the gut bacterial diversity. We used plasma and fecal samples collected during and after treatment from healthy volunteers assigned to a 5-day treatment either by ceftriaxone (1 g every 24 h through IV route), ceftazidime/avibactam (2 g/500 mg every 8 h through IV route), piperacillin/tazobactam (1 g/500 mg every 8 h through IV route) or moxifloxacin (400 mg every 24 h through oral route).

Vector-borne diseases represent various sicknesses that are increasingly significant in human and veterinary health. Among the zoonotic agents transmitted by ticks, infections caused by the intracellular pathogens from the Anaplasmataceae family and piroplasmids (Babesia/Theileria spp.) are particularly notable due to the substantial economic losses they cause in the livestock sector.

Contamination of water bodies is a significant global issue that results from the deliberate release of pollutants into the environment, especially from mining and metal processing industries. The main pollutants generated by these industries are metallic wastes, particularly metals, which can cause adverse effects on the environment and human health. Therefore, it is crucial to develop effective and sustainable approaches to prevent their discharge into the environment.

The research aimed to evaluate the effects of a commercial blend of phytogenic compounds on the digestibility, antioxidant system, intestinal microbiota, and performance of weaned piglets. Two experiments compared three treatments (diets): control, zinc bacitracin (300 g/t) and blended phytogenic compounds (400 g/t). The first experiment analised of digestibility of the dry matter, organic matter, crude protein, crude energy and metabolizable energy, in addition to blood parameters and gut microbiota in 15 piglets commercial cross-bred, weaned at 28 days of age, castrated males, weighing 9.
