D701N mutation in the PB2 protein contributes to the pathogenicity of H5N1 avian influenza viruses but not transmissibility in guinea pigs

open access: yesFrontiers in Microbiology, 2014
H5N1 highly pathogenic avian influenza virus (HPAIV) of clade 2.3.2 has been circulating in waterfowl in Southern China since 2003. Our previous studies showed that certain H5N1 HPAIV isolates within clade 2.3.2 from Southern China had high pathogenicity

Intranasal infection and contact transmission of Zika virus in guinea pigs

open access: yesNature Communications, 2017
Zika virus (ZIKV) is primarily transmitted to humans through mosquito bites or sexual contact. The excretion and persistence of contagious ZIKV in various body fluids have been well documented in ZIKV patients; however, the risk of direct contact ...

MazF ribonucleases promote Mycobacterium tuberculosis drug tolerance and virulence in guinea pigs

open access: yesNature Communications, 2015
Toxin–antitoxin (TA) systems are highly conserved in members of the Mycobacterium tuberculosis (Mtb) complex and have been proposed to play an important role in physiology and virulence.

Changes of lipoperoxidation and antioxidant system in pariodontal tissues in experimental bronchial asthma under conditions of chronic periodonitis and correction of these changes with thiotriazoline

open access: yesJournal of Education, Health and Sport, 2018
We have analyzed the results of the research of changes in indices of lipid peroxidation (conjugated dienes and malondialdehide) and antioxidant (superoxide dismutase, catalase, ceruloplasmin) systems in guinea pigs’ periodontal soft tissues in ...

Сondition of pro-oxidant and antioxidant systems in guinea pigs’ lungs under the condition of immobilization stress.

open access: yesJournal of Education, Health and Sport, 2023
We have investigated the results of alterations in indices of pro-oxidant (conjugated diene and malondialdehyde ) and antioxidant (superoxide dismutase, ceruloplasmin, catalase) systems in guinea pigs’ lungs  under the conditions of immobilization ...

Distribution and Excretion of BisGMA in Guinea Pigs [PDF]

open access: yes, 2008
Bisphenol-A-glycidyldimethacrylate (BisGMA) is used in many resin-based dental materials. It was shown in vitro that BisGMA was released into the adjacent biophase from such materials during the first days after placement.

Condition of pro-oxidant and antioxidant systems in guinea pigs’ lungs under the condition of immobilization stress

open access: yesJournal of Education, Health and Sport, 2021
We have investigated the results of alterations in indices of pro-oxidant (conjugated diene and malondialdehyde) and antioxidant (superoxide dismutase, ceruloplasmin, catalase) systems in guinea pigs’ lungs under the conditions of immobilization stress.

Stapedectomy in the guinea pig

open access: yesOtolaryngology–Head and Neck Surgery, 1999
Stapedectomy has traditionally been studied in the feline model. Ethical considerations and costs have made this model less feasible for ongoing research. The purpose of this study was to examine the guinea pig as a model for research on stapedectomy. Technical difficulties included limited exposure and small dimensions of the ossicles.

Influenza Virus Infection in Guinea Pigs Raised as Livestock, Ecuador

open access: yesEmerging Infectious Diseases, 2012
To determine whether guinea pigs are infected with influenza virus in nature, we conducted a serologic study in domestic guinea pigs in Ecuador. Detection of antibodies against influenza A and B raises the question about the role of guinea pigs in the ...
