Chigger mites comprise three families: Trombiculidae, Leeuwenhoekiidae and Walchiidae, with over 3,000 species worldwide. Their life cycle includes six stages, and the larvae are parasites, while the other stages are free-living predators. Once attached to a host, the larvae spend several days feeding on the host's epithelial tissue, forming the stylostome. An inflammatory reaction can be formed during larval feeding, known as trombiculiasis or trombiculosis. In this study, we provide a literature review using 123 scientific articles on the cases of trombiculiasis in animals and humans reported in different biogeographical regions, including 29 countries and 30 different chigger species, with all the information compiled in the Supplementary material. This review aims to increase the visibility of this disease and group of mites, so that physicians and veterinarians can become more aware of the disease and include the causative agent in differential diagnoses. We also offer knowledge on mounting and control methods in order to improve mite identification for future research. Lastly, the prophylaxis and control methods in cases of infestations and associated pathogens are mentioned.

Treponema denticola, a bacterium that forms a "red complex" with Porphyromonas gingivalis and Tannerella forsythia, is associated with periodontitis, pulpitis, and other oral infections. The major surface protein (Msp) is a surface glycoprotein with a relatively well-established overall domain structure (N-terminal, central and C-terminal regions) and a controversial tertiary structure. As one of the key virulence factors of T.

Gut mucosal immunity of teleost is mainly governed by mucosa-associated lymphoid tissues (MALT) and indigenous microbiota on mucosal surfaces of gut tract, which can confer protection against pathogenic invasion. However, the probiotic features of bacterial isolates from gut tract of triploid cyprinid fish (TCF) were largely unclear. In this study, Lysinibacillus and Enterobacter strains were isolated for probiotic identification.

The neurobiological mechanisms driving the ictal-interictal fluctuations and the chronification of migraine remain elusive. We aimed to construct a composite genetic-microRNA model that could reflect the dynamic perturbations of the disease course and inform the pathogenesis of migraine. We prospectively recruited four groups of participants, including interictal episodic migraine (i.

Background: Carbapenem-Resistant Gram-Negative Bacteria, including Carbapenem-Resistant Enterobacterales (CRE) and Carbapenem-Resistant Pseudomonas aeruginosa (CRPA), are common causes of infections in intensive care units (ICUs) in Italy.
Objective: This prospective observational study evaluated the epidemiology, management, microbiological characterization, and outcomes of hospital-acquired CRE or CRPA infections treated in selected ICUs in Italy.
Methods: The study included patients with hospital-acquired infections due to CRE and CRPA treated in 20 ICUs from June 2021 to February 2023.

Background: The mechanistic pathways that give rise to the extreme symptoms exhibited by rare disease patients are complex, heterogeneous, and difficult to discern. Understanding these mechanisms is critical for developing treatments that address the underlying causes of diseases rather than merely the presenting symptoms. Moreover, the same dysfunctional series of interrelated symptoms implicated in rare recessive diseases may also lead to milder and potentially preventable symptoms in carriers in the general population.
