Estudiando el papel de los neutrófilos polimorfonucleares en la brucelosis
(Revista del Colegio de Microbiólogos Químicos Clinicos Costa Rica, 2015-10)
Las enfermedades infecciosas pueden clasificarse en dos grandes grupos: las agudas y las crónicas. Las bacterias que inducen cuadros crónicos, son en general parásitos intracelulares que tienen tiempos de incubación largos ...
What Is the Evolutionary Fingerprint in Neutrophil Granulocytes?
(University of Veterinary Medicine Hannover, Hannover, Germany, 2020-06-25)
Over the years of evolution, thousands of di erent animal species have evolved. All these
species require an immune system to defend themselves against invading pathogens. Nevertheless,
the immune systems of di erent ...
Pathogenic potential of a Costa Rican strain of 'Candidatus Rickettsia amblyommii' in guinea pigs (Cavia porcellus) and protective immunity against Rickettsia rickettsii
(Ticks and Tick-borne Diseases, 2015-09)
Candidatus Rickettsia amblyommii' is a spotted fever group rickettsia that is not considered pathogenic, although there is serologic evidence of possible infection in animals and humans. The aim of this study was to evaluate ...
The role of neutrophils in Brucellosis
(American Society for Microbiology, 2020-10-14)
Brucellosis is a bacterial disease of domestic animals and humans. The pathogenic ability of Brucella organisms relies on their stealthy strategy and their capacity to replicate within host cells and to induce long-lasting ...
Brucella abortus uses a stealthy strategy to avoid activation of the innate immune system during the onset of infection
(PLOS ONE, 2007-07-18)
Background. To unravel the strategy by which Brucella abortus establishes chronic infections, we explored its early interaction with innate immunity. Methodology/Principal Findings. Brucella did not induce proinflammatory ...
Human neutrophils are resistant to Clostridioides difficile toxin B
(Elsevier, 2022-03-21)
Objective: The main objective of this study was to evaluate the glucosyltransferase activity of C. difficile
TcdB on the activity of human PMNs.
Methods: To better understand the interaction between PMNs and TcdB, PMNs ...
A sensitive blotting system for detection of α-fetoprotein variants with monoclonal and polyclonal antibodies
(Elsevier, 1988-08-19)
Human α-fetoprotein (AFP) variants from cord sera were separated by isoelectric focusing in agarose gels under native conditions, transferred to nitrocellulose paper and detected with polyclonal and monoclonal antibodies ...
Antigenic relationship between the animal and human pathogen Pythium insidiosum and nonpathogenic Pythium species
(American Society for Microbiology, 1987)
Identification of the newly named pathogenic oomycete Pythium insidiosum and its differentiation from other Pythium species by morphologic criteria alone can be difficult and time-consuming. Antigenic anaysis by ...
Comparison of the antibody response in adult cattle against different epitopes of Brucella abortus lipopolysaccharide
(Blackwell, 2001)
The comparison of serological responses in a sample of adult, vaccinated and held-infected bovines with Brucella abortus is reported. Indirect enzyme immunoassav (EIA) titration curves and Western blotting tests for ...
Seroconversión al VDVB en vacas coinfectadas con VLBE y HVB1: fundamento de la calostrogénesis y efecto de la infección persistente causada por el VDVB
(Facultad de Ciencias Agroalimentarias, Universidad de Costa Rica., 2020-09-30)
Los virus de la diarrea viral bovina (VDVB), virus de la leucosis bovina enzoótica (VLBE) y herpesvirus
bovino 1 (HVB1) son patógenos muy importantes en lecherías especializadas debido al impacto negativo que
ocasionan. ...
