| [the incidence of salmonella in the chorizos that are retailed in acapulco, guerrero]. | gastrointestinal disorders are one of the most serious health problems in the mexican republic, and salmonellosis is one of the most prominent therein. with the objective of finding out how chorizos function as carriers of this disease, samples were taken from stores and supermarkets in acapulco, guerrero. 221 samples were collected to investigate the presence of salmonella. these were biochemically examined by means of established techniques from mexico's secretary of health. the results, which ... | 1991 | 2053022 |
| a programme to control taeniasis-cysticercosis (t. solium): experiences in a mexican village. | a study was carried out in a rural community of the state of guerrero in order to find ways to control human taeniasis/cysticercosis (taenia solium). at the beginning of the study the frequency of porcine cysticercosis was established to be around 6.6%. fecal examination in the human population showed that of 760 persons, 24 were carriers of taenia sp (3%). of 440 human sera tested for antibodies against cysticercus cellulosae, 9 showed absorbance values of 0.2 or higher (2.3%). 900 persons rece ... | 1989 | 2488996 |
| [serotypes of salmonella identified in chorizos for sale in acapulco, guerrero, mexico]. | salmonella spp. is one of the most important microorganisms, as public health is concerned, taking into consideration that even in the most developed countries, death has been caused by this microorganism. up to date, there are more than 2200 different serotypes of this pathogen reported due to its antigenic characteristics. in this research, the serotyping of 110 stocks of this microorganism was made, showing a result of 17 different serotypes, from which s. agona, s. derby and s. anatum were t ... | 1993 | 8066333 |
| failure to incriminate domestic flies (diptera: muscidae) as mechanical vectors of taenia eggs (cyclophyllidea: taeniidae) in rural mexico. | flies caught in homes in a rural village in guerrero, mexico, between november 1994 and august 1995 were assessed for their role in the transmission of taenia solium l. most (99%) of the trapped flies were musca domestica l. none of the 1,187 guts or 1,080 legs of the flies contained t. solium eggs. pigs roam freely in this village consuming human fecal material immediately after defecation, thereby limiting fly contact with t. solium eggs. | 2000 | 10916288 |
| re-emergence of vesicular stomatitis in the western united states is associated with distinct viral genetic lineages. | phylogenetic analysis of partial phosphoprotein and glycoprotein gene sequences showed that a single genetic lineage of vesicular stomatitis virus (vsv) serotype new jersey (nj) caused the 1995 and 1997 outbreaks of vesicular stomatitis (vs) in the western united states. while distinct from vsv-nj strains causing previous outbreaks in the western united states and those circulating in feral swine in the southeastern united states, this lineage was closely related to viral lineages circulating in ... | 2000 | 10814582 |
| field trial for reducing porcine taenia solium cysticercosis in mexico by systematic vaccination of pigs. | it has previously been demonstrated that immunization of pigs with a crude extract of taenia solium metacestodes can confer a high level of protection against an egg challenge. furthermore, vaccination of infected animals also induces an immune response against the larvae, which are either destroyed or rendered non-infectious. to assess the efficacy of immunization as a strategy for reducing the prevalence of porcine cysticercosis, a field trial of this vaccine was performed in an endemic area i ... | 1997 | 9187030 |
| immunization against porcine cysticercosis in an endemic area in mexico: a field and laboratory study. | an antigenic extract from taenia solium metacestodes was evaluated for immunogenicity in pig populations from a large area of endemic porcine cysticercosis in the state of guerrero, mexico. a total of 3,295 pigs from 18 villages were immunized with a single dose of 250 micrograms of protein administered intramuscularly. systematic immunization was also performed on pigs (1,076 immunizations) from two of the villages with the highest percentages of cysticercosis. a year after immunization, porcin ... | 1993 | 8214281 |
