Abstract: copaiba oil is a resin extracted from the trunk of trees of copaifera species which grow in brazil where it is widely used in popular medicine as an anti-inflammatory, antiseptic anti-bactericidal, diuretic, dermatological, expectorant, and anti-infective. the comparative study of the composition of commercial copaiba oils was carried out by high resolution gas chromatography (hrgc) and high resolution gas chromatography-mass spectrometry (hrgc-ms) analysis. the commercial oils were compared with authentic oils, collected from the southeast and northern regions of brazil. sixteen commercial oils were analysed and two of them revealed adulterations with fatty acids. using the chromatographic profile of authentic copaiba species oils, it is possible to analyse commercial oils and determine the authenticity of these materials.

Abstract: the false stable fly, muscina stabulans (fallén), was surveyed along an urban-rural gradient at almirante brown, buenos aires province, argentina. samples were taken at monthly intervals from may 2005 to april 2007. hourly captures of adult flies (10:00 am - 04:00 pm) were taken at each sampling date with a hand net. the baits used were 250 g of rotten cow liver and 250 g of fresh dog faeces exposed in shaded and sunny areas. the entire sample accumulated 358 specimens. the number of specimens captured during the second year was higher than in the fi rst year. muscina stabulans was more abundant at urban-suburban sites. females showed significant preferences for cow liver. we caught more specimens in shaded areas. the hourly activity increased toward the afternoon at the three sites. the present work was the first ecological study related to a muscid species in argentina.

Abstract: neospora caninum is a protozoan parasite that affects cattle and dogs, its infections seem to be widely prevalent in chile. to date, nothing is known of the presence of n. caninum in horse population of the country. in south america, two seroprevalence studies have failed to find antibodies in argentina and brazil. the objective of the study was to investigate the presence of n. caninum exposure in horses of chile. sera from 145 asymptomatic horses (87 from ix region and 58 from vii region) were examined for antibodies to neospora using the neospora agglutination test (nat). antibodies (≥ 1:40) to n. caninum were found in 47 (32%) of 145 horses. the results have been also tabulated by breed. this is the first report of presence of antibodies against neospora in horses of chile and south america. although equine clinical neosporosis has not been reported other than from united states, a presuntive diagnosis of the disease should be taken into consideration when evaluating abortion and or central nervous system illness.
Prevalencia de anticuerpos séricos contra Neospora caninum en dos reba?os lecheros de la IX Región de Chile
Archivos de medicina veterinaria , 2000, DOI: 10.4067/S0301-732X2000000200008
Abstract: neosporosis is an important cause of economic loss in the cattle industry throughout the world. in chile, it has been recently detected and,. since then, veterinarians and producers have required information about different aspects of the disease. in this paper we present data of the prevalence of the disease in two dairy herds of the ix region of chile. a commercial indirect fluorescent antibody test (ifa) was performed at 1:200 dilution for bovine and at 1:50 for canine sera. results indicate a 30.2% (52/173, ic=6.8%) infection in bovines from farm "a" and a 15.7% (31/198, ic=5%) in bovines from farm "b" (c2 = 10.42, p = 0.0012). in addition, 57% (4/7) of the dogs from farm "a" had antibodies. differences were observed in each farm as well as amongst age groups: in farm "a" 39.6% (42/106) of heifers and 15.2% (10/66) of cows (c2=10.42, p=0.0012) had antibodies against n. caninum; in farm "b": 22.7% (15/66) of calves, 17.8% (8/45) of heifers and 9.2% (8/87) of cows were positive. there were differences amongst cows, calves and heifers groups (c2=4,07, p=0.043). although it was not the aim of the study it is discussed if the source of infection could be the cause of the difference in prevalence. in contrast with farm "b"," the higher prevalence in farm "a was related to the group fed also with supplements. how the disease spreads in our environment is unknown, different mechanisms could be involved since in most of the farms the animals spend half of the year under confinement and the other half on pasture. the present article gives values of neospora prevalence and preliminary data for further studies on this progressively important disease

Abstract: sera samples from 113 llamas (lama glama) and 127 alpacas (lama pacos) from the ix and v regions, respectively, of chile were tested for toxoplasma gondii antibodies. the modified agglutination test (mat) was used in both species and titers 1:25 were considered diagnostically significant based in previously published data. sera from 49 lamas (43.3%) and 15 alpacas (11.8%) were positive to t. gondii. percentaje seropositivity in serum dilutions of 1:25, 1:50, 1:500 and 1:5000 was 17.6%; 7.9%; 14.1% and 3.5% in lamas and 0%; 2.3%; 0.7% and 8.6% in alpacas, respectively. the rather low prevalence in alpacas may be associated with geographical conditions, management practices or contacts with cats rather than different species susceptibility. as expected, older animals showed higher reactivity of t. gondii than young animals.

Abstract: aromas and fragrances can be obtained through the microbial oxidation of monoterpenes. many microorganisms can be used to carry out extremely specific conversions using substrates of low commercial value. however, for many species, these substrates are highly toxic, consequently inhibiting their metabolism. in this work, the conversion ability of aspergillus niger ioc-3913 for terpenic compounds was examined. this species was preselected because of its high resistance to toxic monoterpenic substrates. though it has been grown in media containing r-limonene (one of the cheapest monoterpenic hydrocarbons, which is widely available on the market), the species has not shown the ability to metabolize it, since biotransformation products were not detected in high resolution gas chromatography analyses. for this reason, other monoterpenes (alpha-pinene, beta-pinene and camphor) were used as substrates. these compounds were shown to be metabolized by the selected strain, producing oxidized compounds. four reaction systems were used: a) biotransformation in a liquid medium with cells in growth b) with pre-grown cultures c) with cells immobilized in a synthetic polymer network and d) in a solid medium to which the substrate was added via the gas phase. the main biotransformation products were found in all the reaction systems, although the adoption of previously cultivated cells seemed to favor biotransformation. cell immobilization seemed to be a feasible strategy for alleviating the toxic effect of the substrate. through mass spectrometry it was possible to identify verbenone and alpha-terpineol as the biotransformation products of alpha-pinene and beta-pinene, respectively. the structures of the other oxidation products are described.
Calliphoridae (Diptera) from wild, suburban, and urban sites at three Southeast Patagonian localities: Calliphoridae (Diptera) de ambientes no habitados, suburbanos y urbanos en tres localidades del sudeste patagónico

Revista de la Sociedad Entomol?3gica Argentina , 2008,
Abstract: species composition, relative abundance, sex ratio and habitat preference of blowflies (diptera: calliphoridae) from caleta olivia, puerto deseado, and puerto san julián (santa cruz province, argentina) were studied during late spring and summer in 2004-2005. results showed a higher prevalence of the exotic species, calliphora vicina (robineau-desvoidy) and phaenicia sericata (meigen) at urban sites over the natives, compsomyops fulvicrura (robineau-desvoidy) and sarconesia chlorogaster (wiedemann), which shows a strong preference for those sampling sites either not inhabited or less influenced by human activities. sex ratio was female biased for all species, except for sarconesia chlorogaster, which exhibited a male prevalence over females.
