In a marine ecosystem, the most sensitive organisms to environmental changes, mainly to anthropic pressures, are fishes and invertebrates. Therefore, they are considered the ideal targets to indirectly evaluate the health of an entire ecosystem. Teleost fishes, particularly those that occupy the highest trophic levels, can accumulate toxic substances through their diet.

Acute gastroenteritis (AGE) represents a world public health relevant problem especially in children. Enteric viruses are the pathogens mainly involved in the episodes of AGE, causing about 70.00% of the cases.

- Rhodococcus equi is a type of bacteria that commonly causes pneumonia in foals, but this report discusses its first documented infection case in a bottlenose dolphin in Italy.
- The dolphin exhibited lung and colon damage during a post-mortem examination and tested positive for dolphin morbillivirus as well.
- Histological analysis confirmed the presence of lesions related to R. equi infection, including specific types of pneumonia and colitis, and whole genome sequencing validated the identification of the bacteria.
Article Synopsis
- Urbanization is increasingly studied for its effects on species movement and gene flow, particularly focusing on how native species adapt or thrive in urban settings.
- Researchers investigated the genetic structure and gene flow of two small mammals (white-footed mice and big brown bats) with differing dispersal abilities in the Providence, Rhode Island metropolitan area.
- The study found that urbanization significantly impacts mice, leading to reduced migration and inbreeding, while bats maintained strong genetic connectivity due to their ability to fly, highlighting the importance of dispersal capacity in urban ecology.
