| arbovirus investigations in argentina, 1977-1980. ii. arthropod collections and virus isolations from argentine mosquitoes. | prospective surveys for arboviruses were carried out in santa fe, corrientes, and chaco provinces, argentina, aperiodically during 1977-1980. a total of 313,233 mosquitoes and 598 biting flies other than mosquitoes were collected and tested for virus in 5,197 and 45 pools, respectively. forty virus strains were isolated, all from mosquitoes, as follows: santa fe province: 4 gamboa group viruses from aedeomyia squamipennis, 1 strain each of st. louis encephalitis virus from culex pipiens quinquef ... | 1985 | 2863989 |
| onset of resistance to fenvalerate, a pyrethroid insecticide in argentine horn flies (diptera: muscidae). | haematobia irritans (l.) horn flies recently have immigrated into argentina from brazil or paraguay. bioassays were conducted with fenvalerate to develop baseline information on pyrethroid susceptibility. four populations tested in 1994 and 1995 were more susceptible than a laboratory strain of horn fly not exposed to insecticides since 1970, but 3 populations from corrientes province tested in 1996 were moderately resistant to fenvalerate, with resistance ratios ranging from 3 to 26. argentine ... | 1998 | 9538580 |
| [colibacillosis in swine: proof of vaccine efficacy]. | the damage caused in the economy and animal sanity by the porcine colibacilosis are significant and they deserve the investigation of preventive measures that give answers to the producers. existing at the present time approximately 21,000 pigs in corrientes and 110,000 in chaco provinces of argentine, the losses for diarrhea that exterminate whole litters, acquire relevance, specially if they can be prevented or cured. for that reason, having 21 strains of enteropathogenic and verocitotoxigenic ... | 1999 | 10932767 |
| genetic analysis of the populations from northern and mesopotamian provinces of argentina by means of 15 autosomal strs. | the allele frequencies for the 15 short tandem repeats included in the power plex-16 kit (promega corp., madison, wi, usa) were determined in a sample of 429 unrelated individuals from five provinces of the northern and northeastern regions of argentina. three northern provinces including salta, formosa and chaco and two within the region surrounded by the paraná and uruguay rivers commonly known as the argentine mesopotamia, including misiones and corrientes. since in this region entre ríos pro ... | 2006 | 16139455 |
| [distribution of lutzomyia longipalpis in the argentine mesopotamia, 2010]. | the first case of visceral leishmaniasis (vl) in argentina was reported in 2006 in posadas, misiones. during the summer 2008-2009 lutzomyia longipalpis, the vl vector, and canine vl cases were already spread along the province of corrientes. in order to know the distribution of vl risk, systematic captures of the vector were performed between february and march 2010, in 18 areas of the provinces of entre ríos and corrientes, and the city of puerto iguazú, misiones, with a total of 313 traps/nigh ... | 2011 | 21296716 |
| total polyphenol content and antioxidant capacity of commercially available tea (camellia sinensis) in argentina. | tea, camellia sinensis (l.) o. kuntze (theaceae) is cultivated in argentina in the northeastern region (provinces of misiones and corrientes), between 26 degrees and 28 degrees south latitude, the southernmost area of the world where tea is cultivated. the objective of this work was to determine the total polyphenol content and the in vitro antioxidant capacity of green and black tea cultivated and industrialized in argentina. twelve samples of eight brands were analyzed. the total polyphenol co ... | 2008 | 18778031 |
| molecular analysis of populations of ctenomys (caviomorpha, rodentia) with high karyotypic variability. | the tuco-tucos (ctenomys) are south american subterranean rodents that are some of the most chromosomally variable of all mammals. in this study we focus on ctenomys of the "corrientes species group" from that argentine province and consisting of c. dorbignyi, c. perrensi, c. roigi and unnamed populations (ctenomys sp.). a diploid range of 41-70 has been demonstrated for these taxa with multiple robertsonian changes, pericentric inversions, heterochromatic modifications and other chromosomal rea ... | 2002 | 12438789 |
| occurrence and toxicity of microcystis aeruginosa (cyanobacteria) in the paraná river, downstream of the yacyretá dam (argentina). | cyanobacteria constitute the main toxin producers in inland water ecosystems and have extensive global distribution. the presence of hepatotoxins in aquatic environments is hazardous to human and animal health; even though the presence and identification of hepatotoxic microcystins in rivers and reservoirs of the world have been confirmed by several studies in the last few years. herein, we studied the abundance and toxicity of microcystis aeruginosa in the argentine section of the paraná river ... | 2016 | 28862419 |
| two new records of ceratocanthinae from northeastern argentina (coleoptera: scarabaeoidea, hybosoridae). | germarostes (haroldostes) rugiceps (germar) and germarostes (haroldostes) diffundus (petrovitz) (ceratocanthinae) are recorded for the first time for argentina from misiones and corrientes, respectively. this brings to thirteen the total number of the ceratocanthinae species recorded for argentina up to now. some remarks on the type series of g. diffundus and on the collecting circumstances of the argentine specimens in here discussed are included. | 2017 | 19347110 |
