St. Louis encephalitis virus (SLEV) and West Nile virus (WNV) belong to the Japanese encephalitis antigenic complex (Flavivirus genus, Flaviviridae family). They show antigenic close relationships and share many similarities in their ecology. Both are responsible for serious human diseases. The aim of this study was to investigate the presence of neutralizing antibodies to these viruses in hors...
The objective of this study was to estimate the true prevalence of individual chickens serologically test-positive against avian pneumovirus and Ornithobacterium rhinotracheale in Uruguay. Seventeen different broiler farms existed in three different provinces in Uruguay were recruited and the 1861 broilers were investigated. Individual-chicken sera were analyzed using a commercial enzyme-linked...
Community-associated MRSA (CA-MRSA) strains have emerged in Uruguay. We reviewed Staphylococcus aureus isolates from a large healthcare facility in Montevideo (center A) and obtained information from 3 additional hospitals on patients infected with CA-MRSA. An infection was defined as healthcare-onset if the culture was obtained >48 hours after hospital admission. At center A, the proportion of...

We develop and test a model that relates leadership behaviors, organizational commitment, and organizational citizenship behaviors (OCBs). We test the model using structural equations with a sample of 116 doctors from Uruguay. Consistent with expectations, our results show that transactional leadership behaviors increase followers’ continuance commitment and decrease their growth commitment, wh...
During 5,230 trapping nights, 672 small mammals were trapped in the areas where most hantavirus pulmonary syndrome (HPS) cases occur in Uruguay. Yellow pygmy rice rats (Oligoryzomys flavescens) were the only rodents that showed evidence of antibodies to hantavirus, with a seroprevalence of 2.6%. The rodents were trapped in all the explored environments, and most of the seropositive rodents were...
We present a systematic study of Scapteromys populations from Argentina, Paraguay, and Uruguay, based on molecular and morphological evidence. First, based on DNA sequences (801 base pairs) from the mitochondrial cytochrome-b gene, we found that Scapteromys populations fall into 2 main clades; 1 formed by Argentinean and Paraguayan populations together with 1 population from western Uruguay, an...
The objective of this work was to characterize bruises in bovine carcasses in Uruguay and to evaluate the economic impact. Thirteen abattoirs were visited during 2 years and bruises were identified, classified, and quantified by zone and degree (depth and size). One hundred carcasses were separated and bruises were cut out and weighed separately. From a total of 15 157 carcasses observed, 60.0%...
Rhizobium leguminosarum bv trifolii is the effective nitrogen fixing microsymbiont of a diverse range of annual and perennial Trifolium (clover) species. Strain WSM2304 is an aerobic, motile, non-spore forming, Gram-negative rod, isolated from Trifolium polymorphum in Uruguay in 1998. This microsymbiont predominated in the perennial grasslands of Glencoe Research Station, in Uruguay, to competi...
