Antibiotic‐Induced Dysbiosis of the Gut Microbiota Shifts Host Tryptophan Metabolism and Increases the Susceptibility of Mice to Pulmonary Infection With Pseudomonas aeruginosa

Immunology, Volume 175, Issue 4, Page 453-466, August 2025.
Antibiotic‐induced dysbiosis of the gut microbiota shifts host tryptophan metabolism and impairs the innate immune response during Pseudomonas aeruginosa pulmonary infection. (A) Eubiosis: During eubiosis, the intestinal microbiota metabolises tryptophan into indole metabolites, which keeps tryptophan levels within normal serum concentrations. However,

Desempenho de Thyrinteina arnobia Stoll (Lepidoptera: Geometridae) em eucalipto e goiaba: o hospedeiro nativo não é um bom hospedeiro? [PDF]

Neotropical Entomology, 2003
Plants can develop mechanisms of defense that reduces the effects of herbivore attacks. In response, the herbivores evolve to breaking the defense mechanisms of plants. Herbivores may also escape from the plant defense system by migrating to other host whose defense is not effective against them.

Analysis of the immunomodulatory properties of mycobacterium cell wall fraction on the cytokine production of peripheral blood mononuclear cells of healthy dogs

Veterinary Dermatology, Volume 35, Issue 6, Page 595-604, December 2024.
Background – Mycobacterium cell wall fraction (MCWF) is derived from nonpathogenic Mycobacterium phlei and is used as an immunomodulatory compound in clinical practice, yet its mode‐of‐action requires further research. Objective – To evaluate the host response to MCWF in canine peripheral blood mononuclear cells (PBMCs) by using enzyme‐linked ...

Efeitos da esplenectomia nas relações tumor-hospedeiro [PDF]

Memórias do Instituto Oswaldo Cruz, 1971
Foi estudada a evolução do sarcoma de Yoshida em ratos esplenectomizados. A remoção do baço favoreceu o desenvolvimento do tumor, indicando que êste órgão perticipa de um mecanismo de defesa antitumoral. Os dados demonstraram também, que o tempo trancorrido entre a esplenectomia e o transplante da neoplasia, é um fator importante na observação do ...

Cytological evaluation, culture and genomics to evaluate the microbiome in healthy rabbit external ear canals

Veterinary Dermatology, Volume 35, Issue 5, Page 479-491, October 2024.
Background – Lop‐eared rabbits may be predisposed to otitis externa (OE) as a consequence of their ear conformation. Although otoscopy, otic cytological evaluation, and culture are valuable tools in dogs and cats, published data on rabbits remain lacking. Hypothesis/Objectives – This study aimed to assess the utility of otoscopy and cytological results

Update on the skin barrier, cutaneous microbiome and host defence peptides in canine atopic dermatitis

Veterinary Dermatology, Volume 35, Issue 1, Page 5-14, February 2024.
Background – Canine atopic dermatitis (AD) is a complex inflammatory skin disease associated with cutaneous microbiome, immunological and skin barrier alterations. This review summarises the current evidence on skin barrier defects and on cutaneous microbiome dysfunction in canine AD.
