Global warming has had serious implications on dispersion of infectious diseases like toxoplasmosis. Since the frequency Toxoplasma gondii largely depends climatic conditions, we studied its prevalence by means 3599 samples National Health Survey 2000 (NHS-2000) and 2916 Nutrition 2006 (NHNS-2006) serum banks, obtained from 1–98 year old subjects both genders all states Mexico. Anti-T.gondii IgG antibodies were determined ELISA confirmed western blot. Crude, epidemiologically weighted...
A diverse group of professionals gathered in Brasília for the VI Brazilian Symposium on Toxoplasmosis and III International from October 17 to 19, 2023. Guided by ‘One Health’ concept, event addressed toxoplasmosis its human, animal, environmental dimensions. Participants discussed strategies improve prevention, diagnosis, treatment disease Brazil, also emphasizing a Pan-American cooperation. The resulting document, Letter: Proposal Control Brazil with Multidisciplinary Approach Cooperation...
SUMMARY Infection of ewes by Toxoplasma gondii may induce abortions, thus it has consequences for sheep production. Colima, Western State Mexico, favourable climatic conditions transmission and both domestic wild cats live there. The aim this study was to determine the frequency specific antibodies in from coast, a mountain, hill Colima. Serum samples 351 were tested previously standardized indirect ELISA. infection estimated farm location flock size, as well animals' age sex analysed risk...
Saffron, the dried stigmas of Crocus sativus L., is widely used mainly as herbal medicine or food coloring, and a flavoring agent. It cultivated only in few countries around world. Comparative analytical semi-preparative High Performance Liquid Chromatography (HPLC) studies using photodiode array analyses were performed on Waters HPLC system for separation several ingredients from alcoholic extracts four different saffron types. Ten peaks identified by comparison their retention times with...
The effect of transfluthrin (TF) or D-allethrin (DA) pyrethroid (PYR) vapors, often contained as main ingredients in two commercially available mosquito repellent mats, on cytochrome P450 (CYP) enzymes rat brain and liver was assessed. Immunodetection CYP2E1 CYP3A2 proteins revealed their induction cerebrum cerebellum, but not microsomes rats exposed by inhalation to TF DA. This overexpression correlated with an increase catalytic activities. specifically increased expression CYP isoenzymes,...
Genotyping and virulence studies of Toxoplasma gondii are essential to investigate the pathogenesis strains circulating worldwide. In this study, eight T. isolates obtained from a congenitally infected newborn, calf, two cats, three dogs, wallaby five states México were genotyped by Mn-PCR-RFLP with 11 typing markers (SAG1, SAG2 5'3', alt. SAG2, SAG3, BTUB, GRA6, c22-8, c29-2, L358, PK1 Apico), (CS3, ROP16, ROP17, ROP18 ROP5), 15 microsatellite (TUB-2, W35, TgM-A, B18, B17, M33, IV.1, XI.1,...
The aim of this study was to assess the prevalence Toxoplasma gondii infection in rodents that coexist with ocelots north-eastern Mexico. Eighty five genera were captured and their serum samples tested for specific IgG antibodies T. by in-house indirect ELISA using three different conjugates. Prevalences 7% (3/44) 33% (4/12) found Sigmodon hispidus Liomys irroratus, respectively, significantly different. All Baiomys taylori Oligoryzomys fulvescens negative presence anti-T. antibodies. from...
SUMMARY An indirect ELISA and an immunoblot were standardized to detect anti- Toxoplasma gondii antibodies in sheep, compared with a commercial as reference. Sensitivity was 92·0 96·0%, specificity 88·0 75·0%, respectively. Then the serum samples of 103 sheep on ranch located Eastern region Mexico analysed. A frequency ranging from 77 84% observed, heterogeneous pattern among animals by immunoblotting. Ten months later 56 sampled tested again. Six became negative while 1 case first time...
has at least 318 genotypes distributed worldwide, and tropical regions usually have greater genetic diversity. Campeche is a state located in the southeastern region of México favourable climate conditions for replication dissemination this protozoan, similar to those South American countries where broad diversity been described. Thus, study, 4
Purification of the lectin from Phaseolus acutifolius var. escumite was achieved by affinity chromatography on a column containing glutaraldehyzed membranes blood group O erythrocytes. The is tetrameric glycoprotein 121 kDa with 10% sugar weight composed four subunits 30 as determined SDS-PAGE. isolectins ion-exchange mono-S column. and its showed identical NH2 terminal residues (ANDLSFNFQR FNETN) homology to PHA leucoagglutinin-precursor. Peptide mass fingerprint each isoform tryptic...
Toxoplasma gondii is a protozoan parasite with broad ecological valence, which has been detected in wide range of hosts and landscapes. Although the genus considered monospecific, recent years it demonstrated to exhibit more genetic variability than previously known. In Mexico, there are few genotyping studies, suggest that classical, autochthonous, atypical strains circulating. The goal this study was describe T. diversity naturally infected sheep from Colima, Mexico. This good site aspects...
Abstract Background Currently, more than 300 genotypes of Toxoplasma gondii ( T. gondii) have been described throughout the world, demonstrating its wide genetic diversity. The SAG3 locus is one genes included in genotyping panel this parasite. It associated with virulence since it participates during invasion process host cells. Therefore, cloning, sequencing, and bioinformatic analysis were used to deepen understanding diversity blood samples from feral cats. Results Six different...
Introduction: There are few articles on evaluation of Toxoplasma gondii serological tests. Besides, commercially available tests not always useful and expensive for studies in open population. The aim this study was to evaluate in-house ELISA western blot IgG antibodies a representative sample people living Mexico. Methodology: Three hundred five serum samples were randomly selected from two national seroepidemiological survey banks; they taken men women all ages areas the country. cut-off...
