[control of hydatidosis in the province of rio negro, argentina: epidemiology].	in this paper we attempt to present a general view of the situation of hydatidosis in the province of rio negro, argentina, considering the magnitude of infection in man and dog. because of its seriousness a 10 year program for the control of hydatidosis has been carried out, which included veterinary and medical care. the number of human cases with hydatidosis in the period 1981-1988 was determined by a retrospective study of the registers of public health. from 1188 cases registered in the per ...	1991	1843859
[hydatidosis control in the province of río negro, argentina: evaluation of the veterinary health care activities. 1].	hydatidosis constitutes a serious public health problem in the province of rio negro, argentine. this situation has promoted the implementation of a control programme, carried out in 1979. the accumulated experience of 13 years works is presented in this study.	1994	7716409
genetic variation and epidemiology of echinococcus granulosus in argentina.	polymerase chain reaction-ribosomal its-1 dna (rdna) restriction fragment length polymorphism (pcr-rflp) analysis and sequencing of the mitochondrial cytochrome c oxidase subunit 1 (co1) and nadh dehydrogenase 1 (nd1) genes were used to characterize 33 echinococcus granulosus isolates collected from different regions and hosts in argentina, and to determine which genotypes occurred in humans with cystic hydatid disease. the results of the study demonstrated the presence of at least 4 distinct ge ...	1999	10363285
[asymptomatic carriers of hydatidosis: epidemiology, diagnosis, and treatment].	until a short time ago, hydatidosis was considered a pathology that could only be resolved surgically. however, in recent years progress has been made with the epidemiology, diagnosis, and treatment of the disease, and new information on the natural history of hydatidosis has helped define new criteria for its treatment. it is now known that as many as 67% of the carriers of liver cysts who are asymptomatic remain so throughout their lives. this situation produces special results in immunologic ...	2000	11141967
rate of infection and of reinfection by echinococcus granulosus in rural dogs of the province of rio negro, argentina.	hydatidosis (cystic echinococcosis) constitutes a serious public health problem in the province of rio negro, argentina. in the present work it was intended to evaluate the prevalence of the canine echinococcosis in rural areas of the province of rio negro and studied the reinfection rate in dogs after treatment with praziquantel during the period 1980-1997. a total of 496 dogs were studied in 18 canine concentrations in order to establish the initial prevalence rate which was 42.3%. from 1980 o ...	2000	10669098

epidemiological surveillance of human hydatidosis by means of ultrasonography: its contribution to the evaluation of control programs.	epidemiological surveillance for hydatidosis is based on initial determination and follow-up of the infestation rate in man, sheep and dogs. the use of ultrasonography (us) as a screening method has demonstrated its usefulness in detecting asymptomatic human carriers of abdominal hydatidosis. to evaluate the contribution of us to epidemiological surveillance within the framework of disease control programs, we performed 719 us studies in school children from 7 to 13 years of age, in rural areas ...	2001	11412805
ovine echinococcus granulosus transmission dynamics in the province of rio negro, argentina, 1980-1999.	in this work, the impact of a hydatidosis control programme for dogs on the intermediate ovine host was specifically analysed to determine the levels of prevalence achieved and the dynamics of parasite transmission, as well as to evaluate the quality of diagnostic systems in slaughterhouses. a field study was conducted in four slaughterhouses (valcheta, los menucos, jacobacci, bariloche) that process animals coming from all the departments within the work area. the control programme for dogs ent ...	2001	11423184
a case-control study of the risk factors for cystic echinococcosis among the children of rio negro province, argentina.	in 1984 the prevalence of cystic echinococcosis (ce) in rio negro province in central argentina reached alarming levels, with almost 6% of children aged 7-13 years infected with the causative agent, echinococcus granulosus. although the control activities developed between 1980-2000 have now lowered the prevalence of infection in this age-group to 1.1%, transmission of e. granulosus has clearly not ceased. the aim of the present study was to identify possible flaws in the control programme and t ...	2002	11989533
diagnosis of cystic echinococcosis on sheep farms in the south of argentina: areas with a control program.	in 2000 guarnera et al. proposed using elisa in canine faeces collected from the ground to detect dogs infected with echinococcus granulosus, thus determining sheep farms with active transmission. the objective was to evaluate the prevalence of e. granulosus infection in sheep farms of the patagonia. sheep farms were randomly selected in the provinces of río negro, chubut, neuquén, santa cruz and tierra del fuego (areas with control programs) and la pampa (comparison area). from one to three sam ...	2004	15725535
[epidemiological surveillance of cystic echinococcosis in dogs, sheep farms and humans in the rio negro province].	the surveillance of infection for echinococcus granulosus in the province of rio negro during 1980-2002 included serological and ultrasonographic screening in humans and arecoline test in dogs. in lieu of the limitations of the arecoline test the proposal was to supplant that test for the copro elisa-copro/western blot complex applied to feces collected from the environment. the objective was to compare the pros and cons of the two tests and to evaluate the human and the canine infection prevale ...	2006	16871904
