We evaluate the prevalence of intestinal parasites in 504 people and degree association between environmental variables found population, soil water a rural area Argentina during 2002-2003. A structured survey was used to fecal-human, samples were analyzed. The 45.4%. Most prevalent protozoa Blastocystis hominis (27.2%) Giardia lamblia (6.9%), while most helminth Ascaris lumbricoides (3.8%). analyzed showing (p < 0.05) with presence population were: cardboard-tin or wooden house, dirt...
The purpose of this study was to investigate the genotypes Giardia lamblia from human and animal feces their epidemiological clinical characteristics in Argentina, South America. Seventy isolates, 60 humans (adults children), eight dogs two cows were processed by polymerase chain reaction-restriction fragment length polymorphism. Data corresponding demographic, socio-cultural environmental variables presence/absence signs/symptoms collected. triosephosphate isomerase gene amplified 43...
Abstract Environmental parameters influencing the distribution of parasite species in three neighbourhoods differing socioeconomic conditions La Plata, Argentina were analysed. Coproparasitological screenings performed children up to 14 years old from a marginal zone (100), suburban neighbourhood (101), and an urban area (91) 1999--2000. The presence environmental samples (water soil) degree association among communities was documented evaluated. prevalence infection each population 73.0%,...
Introduction: Intestinal parasitic infections have been reported in different regions of Argentina. Giardia intestinalis is recognized as "the national parasite". The aim this work was to determine the prevalence both intestinal parasites and G. genotypes, well analyze clinical epidemiological characteristics schoolchildren from a suburban community. Methodology: Serial coproparasitological analysis perianal swab method were performed 244 schoolchildren. Demographic, sociocultural...
The objective of this study was to evaluate the relationship between toxocariasis frequency and demographic, environmental, sanitary variables, eosinophylia, other intestinal parasites in a rural population Argentina. Serological examination 100 individuals carried out by using ELISA technique for detection anti-toxocara antibodies. Eosinophiles peripheral blood, presence parasites, socio-cultural data were evaluated. Eighty-one feces samples dogs belonging studied people analyzed detect...
The aim of the present paper was to evaluate larvicidal effect Enterococcus faecalis CECT7121 (Ef7121) on Toxocara canis cycle both in vitro and vivo. For experiments, T. larvae were incubated with supernatants Ef7121 (EI) mutant (EIm), a pre-culture (EII) fresh culture (EIII) strain (EIIIm). viability calculated after 48 h incubation. A significant reduction observed EI, EII EIII. decrease this inhibitory EIm EIIIm (p = 0.008). In vivo mice orally inoculated three doses Ef7121. To study...
In a study, carried out in 2000, of the clinical and parasitological status Wichi Aboriginal community living suburbs Tartagal, northern Salta, Argentina, 154 individuals were screened for parasitic infections. Ninety-five faecal samples also obtained from same population. Ninety-three percent subjects positive 1 or more parasites investigated by direct test 70.5% them had superinfection. The most frequent helminths Strongyloides stercoralis (50.5%) hookworm (47.4%). We found low reinfection...

Objective. To evaluate the effectiveness of an intervention based on training and use a protocol with automatic stop antimicrobial prophylaxis to improve hospital compliance surgical antibiotic guidelines. Design. An interventional study before-after trial was conducted in 3 stages: 3-year initial stage (January 1999 December 2001), during which descriptive-prospective survey performed site infections; 6-month second June 2002), educational regarding routine request form that included (the...
The protozoan parasite most frequently associated with diarrhoea worldwide is Giardia intestinalis. In 2005, a study was initiated to identify the genotypes of this infecting children in Argentinian provinces Buenos Aires, Mendoza and Chaco, explore associations between genotype detected child, characteristics child's household clinical presentation. Overall, 998 (504 boys 494 girls) aged 2–14 years, or without symptoms, were enrolled. G. intestinalis 94 117 stool samples found positive for...
Blastocystis spp. es el protista intracelular que se detecta con mayor frecuencia en muestras de materia fecal humana; las tasas infección pueden superar 20% países vías desarrollo. El hallazgo este parásito heces diversas especies animales sugiere su potencial zoonótico. La relevancia clínica y papel patógeno tracto intestinal son inciertos. Varias publicaciones lo reconocen como agente etiológico desórdenes intestinales diarrea, enfermedad inflamatoria colitis ulcerosa, aunque la...
The aim of this study was to relate personal data, socio-cultural and environmental characteristics, the presence symptoms/signs with frequencies Giardia spp. Blastocystis hominis among a rural population in Buenos Aires Province, Argentina. Of surveyed (350), 3.7% were infected only or 22.9% B. hominis, 2.3% both protozoa. frequency infection according sex; 6.1% males 1.6% females by spp., 26.7% 19.5% 2.4% 2.2% parasites, respectively. detected three adults (over 14 years), but more...
OBJETIVOS: Diseñar, implementar y evaluar un plan complejo de acciones dirigido a reducir las parasitosis en una localidad rural la provincia Buenos Aires, Argentina, con participación comunidad. MÉTODOS: El trabajo se realizó General Mansilla, tres etapas. 1) Se evaluó situación epidemiológica inicial intestinales comunidad mediante análisis coproparasitológico seriado escobillado anal muestra 522 personas. 2) implementaron dos intervenciones: el tratamiento farmacológico personas...
Enterococci are part of the indigenous microbiota human gastrointestinal tract and food animal origin. inhabiting non-human reservoirs play a critical role in acquisition dissemination antimicrobial resistance determinants. The aim this work was to investigate Enterococcus faecalis faecium strains recovered from artisanal Samples goat cheese (n = 42), cow 40), salami 30), minced meat for manufacture hamburgers 60) were analyzed. Phenotypic genotypic tests species-level identification...
