Criterios diagnósticos para la infección por el virus de la inmunodeficiencia felina y el virus de la leucemia felina en gatos domésticos de Buenos Aires, Argentina
Viral diagnostic criteria for Feline immunodeficiency virus and Feline leukemia virus infections in domestic cats from Buenos Aires, Argentina

Rev. argent. microbiol; 48 (4), 2016
A cross-sectional study was carried out on cats attending the Small Animal Hospital at the Faculty of Veterinary Sciences of the University of Buenos Aires to assess the prevalence and associated risk factors of Feline immunodeficiency virus (FIV) and Feline leukemia virus (FeLV) in the city of Buenos Ai...

La rizobacteria promotora del crecimiento vegetal Arthrobacter agilis UMCV2 coloniza endofíticamente a Medicago truncatula
The plant growth-promoting rhizobacterium Arthrobacter agilis UMCV2 endophytically colonizes Medicago truncatula

Rev. argent. microbiol; 48 (4), 2016
Arthrobacter agilis UMCV2 es una bacteria rizosférica que promueve el crecimiento vegetal de plantas leguminosas proveyéndoles hierro soluble. Un segundo mecanismo de promoción se da a través de la producción de compuestos volátiles que estimulan los mecanismos de absorción de hierro. Adicionalmen...

Primer reporte de Toxocara cati en el caracol doméstico Rumina decollata
First report of Toxocara cati in the domestic land snail Rumina decollata

Rev. argent. microbiol; 48 (3), 2016
Se estudió el rol prospectivo de Rumina decollata como potencial hospedador paraténico de Toxocara cati para los gatos domésticos. Se recolectaron caracoles R. decollata y heces de gatos de un hospital de la Ciudad Autónoma de Buenos Aires. Se procesaron las heces y los caracoles fueron digeridos par...

Detección molecular de Sarcocystis aucheniae en sangre de llamas de Argentina
Molecular detection of Sarcocystis aucheniae in the blood of llamas from Argentina

Rev. argent. microbiol; 48 (3), 2016
Sarcocystis aucheniae are apicomplexan protozoa that infect South American camelids (SACs), giving rise to macroscopic cysts similar to rice grains in skeletal muscles. Visual detection of macrocysts in slaughtered animals hampers commercialization of SAC meat, a highly relevant economic exploitation for...

Comparison of PCR-based methods for the simultaneous detection of Neisseria meningitidis, Haemophilus influenzae, and Streptococcus pneumoniae in clinical samples

Braz. j. infect. dis; 20 (4), 2016
Abstract Background Several in-house PCR-based assays have been described for the detection of bacterial meningitis caused by Neisseria meningitidis, Streptococcus pneumoniae, and Haemophilus influenzae from clinical samples. PCR-based methods targeting different bacterial genes are frequently used by d...

Asn336 is involved in the substrate affinity of glycine oxidase from Bacillus cereus

Electron. j. biotechnol; 19 (4), 2016
Background: Glycine oxidase (GO), a type of D-amino acid oxidase, is of biotechnological interest for its potential in several fields. In our previous study, we have characterized a new glycine oxidase (BceGO) from Bacillus cereus HYC-7. Here, a variant of N336K with increased the affinity against all th...

Mycobacterium paratuberculosis detection in cow's milk in Argentina by immunomagnetic separation-PCR

Braz. j. microbiol; 47 (2), 2016
Abstract The aim of this study was to standardize a diagnosis procedure to detect Mycobacterium avium subsp. paratuberculosis (Map) DNA in raw cow milk samples under field conditions. A procedure that combines both immunomagnetic separation and IS900 -PCR detection (IMS-IS1 PCR) was employed on milk samp...

Design of an allele-specific PCR assay to genotype the rs12255372 SNP in a pilot study of association between common TCF7L2 polymorphisms and type 2 diabetes in Venezuelans

Objective The global burden of diabetes mellitus will impact strongly American countries in the coming decades. Type 2 diabetes mellitus (T2DM) is a multifactorial disease and the basis for its genetic susceptibility remains not fully understood. Different population studies have demonstrated that varian...

Detección de Brachyspira pilosicoli y otras especies de Brachyspira en granjas avícolas argentinas
Detection of Brachyspira pilosicoli and other Brachyspira species in Argentine poultry farms

Rev. argent. microbiol; 48 (1), 2016
Algunas especies del género Brachyspira, como Brachyspira pilosicoli, Brachyspira intermedia y Brachyspira alvinipulli, son especies patógenas capaces de producir enfermedad en gallinas ponedoras. En nuestro país, la presencia de B. pilosicoli y otras especies de Brachyspira ha sido informada en cerdo...

Un método basado en la PCR para la identificación rápida de levaduras acumuladoras de astaxantina (Phaffia spp. )
PCR-based method for the rapid identification of astaxanthin-accumulating yeasts (Phaffia spp.)

Rev. argent. microbiol; 48 (1), 2016
It has been recently found that the natural distribution, habitat, and genetic diversity of astaxanthin-producing yeasts (i.e. Phaffia rhodozyma, synonym Xanthophyllomyces dendrorhous) is much greater than previously thought. P. rhodozyma is biotechnologically exploited due to its ability to produce the ...
