Host‐Parasite Relationship of Ticks (Acari: Ixodidae and Argasidae) and Feral Pigs (Sus scrofa) in the Nhecolândia Region of the Pantanal Wetlands in Mato Grosso do Sul

open access: yesInternational Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013
Feral pigs (S. scrofa) were introduced to the Pantanal region around 200 years ago and the population appears to be in expansion. Its eradication is considered to be impossible. The population of feral pigs in the Pantanal wetlands is currently estimated at one million. Two scientific excursions were organized.

Experimental Drought Suppresses Amphibian Pathogen Yet Intensifies Transmission and Disrupts Protective Skin Microbiome [PDF]

open access: yesGlobal change biology.
This study used ecologically realistic enclosures with pumpkin toadlets to simulate short‐term drought conditions in Brazil's Atlantic Forest. Drought reduced the overall levels of a harmful amphibian fungus, but it also disrupted their protective skin‐associated bacteria and caused the toadlets to cluster in wet areas of the enclosures, which ...

Indole‐Acetic Acid Impairs Pseudomonas aeruginosa Virulence and Alters Lung Infection in Mice

open access: yesMicrobiologyOpen, Volume 14, Issue 6, December 2025.
Screening for anti‐virulence activity exerted by tryptophan catabolites on laboratory and clinical strains of Pseudomonas aeruginosa showed that Indoleacetic acid (IAA) inhibits motility and pigment production, downregulates PQS gene expression, while increases oxidative stress sensitivity.

Spatio-Temporal Cluster Detection of Dengue, Chikungunya, and Zika Viruses’ Infection in Rio de Janeiro State from 2010 to 2019

open access: yesViruses, 2023
Dengue (DENV), chikungunya (CHIKV), and Zika (ZIKV) virus infections are widespread throughout the Rio de Janeiro state. The co-circulation of these emergent arboviruses constitutes a serious public health problem, resulting in outbreaks that can ...

Taenia taeniaeformis: aspectos da relação hospedeiro-parasita [PDF]

open access: yesMemórias do Instituto Oswaldo Cruz, 1982
Gatos eliminam proglotes de Taenia taeniaeformis vinte dias após a ingestão de Cysticercus fasciolares obtidos de ratos albinos infectados dois meses e meio após a ingestão de ovos viáveis. A resposta imunológica humoral de gatos e ratos foi detectada a partir da segunda semana de infecção, sendo observado maiores níveis de anticorpos circulares na ...

A Deadly Ride: The Interaction Between the Tortoise Beetle Botanochara impressa and the Parasitoid Wasp Emersonella niveipes

open access: yesAustral Ecology, Volume 50, Issue 12, December 2025.
ABSTRACT Parasitoid insects can significantly influence the dynamics of terrestrial ecosystems due to their interactions with phytophagous insects. Tortoise beetles (Cassidinae s. str., Coleoptera, Chrysomelidae) are one of the most parasitized groups of Coleoptera.

Host–parasite relationship in urban environments: A network analysis of haemoparasite infections in Nasua nasua Linnaeus (South American coati)

open access: yesMedical and Veterinary Entomology, Volume 39, Issue 3, Page 456-463, September 2025.
Urban environments alter host–parasite dynamics, as seen in Nasua nasua, where haemotropic Mycoplasma plays a key role in parasite spread through frequent social interactions. Network analysis revealed low modularity in interactions between N. nasua and tick‐borne haemoparasites, with functional roles unaffected by biotic factors, tick infestation or ...

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

open access: yesNeotropical 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.
