Characterization of genomic island 3 and genetic variability of Chilean field strains of Brucella abortus
(2011)
One of the capabilities developed by bacteria is the ability to gain large fragments of DNA from other bacteria or to lose portions of their own genomes. Among these exchangeable fragments are the genomic islands (GIs). ...
Importance of tissue sampling, laboratory methods, and patient characteristics for detection of Pneumocystis in autopsied lungs of non-immunosuppressed individuals
(Springer Verlag, 2017)
© 2017, The Author(s).To understand the epidemiological significance of Pneumocystis detection in a lung tissue sample of non-immunosuppressed individuals, we examined sampling procedures, laboratory methodology, and patient ...
Racial tropism of a highly toxic clone of Actinobacillus actinomycetemcomitans associated with juvenile periodontitis
(1997)
Actinobacillus actinomycetemcomitans strains with enhanced levels of production of leukotoxin are characterized by a 530-bp deletion from the promoter region of the leukotoxin gene operon. Previous isolates with this ...
Enterohemorrhagic Escherichia coli associated with hemolytic-uremic syndrome in Chilean children
(1992)
A clinicoepidemiological study was undertaken to determine if enterohemorrhagic Escherichia coli (EHEC) was associated with hemolytic- uremic syndrome (HUS) in children in Santiago, Valdivia, and Temuco, Chile. Prospective ...
Prospective study of Campylobacter jejuni infection in Chilean infants evaluated by culture and serology
(1989)
A prospective study of Campylobacter jejuni infection was performed during a 6-month period in a cohort of 198 Chilean infants. Surveillance was based on biweekly home visits by a team of trained nurses. C. jejuni colonization ...
Epidemic typhoid in Chile: Analysis by molecular and conventional methods of Salmonella typhi strain diversity in epidemic (1977 and 1981) and nonepidemic (1990) years
(1996)
From 1977 to 1986, Chile experienced an important typhoid fever epidemic, despite statistics that indicated apparently improving levels of sanitation of drinking water and sewage disposal. The lack of antibiotic resistance ...
Clonal diversity of Chilean isolates of enterohemorrhagic Escherichia coli from patients with hemolytic-uremic syndrome, asymptomatic subjects, animal reservoirs, and food products
(1999)
To determine clonal relationship among Chilean enterohemorrhagic Escherichia coli (EHEC) strains from different sources (clinical infections, animal reservoirs, and food), 54 EHEC isolates (44 of E. coli O157, 5 of E. coli ...
JC polyomavirus circulation in one-year surveillance in wastewater in Santiago, Chile
(Elsevier B.V., 2019)
Human polyomavirus JC (JCPyV) is a widely distributed viral agent and because it high resistance against environmental conditions it is frequently recovered from diverse sources of water and is considered a good marker for ...
A differential DNA methylome signature of pulmonary immune cells from individuals converting to latent tuberculosis infection
(Springer Nature, 2021)
Tuberculosis (TB), caused by Mycobacterium tuberculosis, spreads via aerosols and the first encounter with the immune system is with the pulmonary-resident immune cells. The role of epigenetic regulations in the immune ...
