Differential cultivars and molecular markers were used to analyze 59 isolates of the bean anthracnose pathogen, Colletotrichum lindemuthianum, from different regions Mexico. Ten distinct races determined, three which had not been reported previously in Isolates found infect only a narrow range differential restricted Middle American origin. A comparison random amplified polymorphic DNA fragment length polymorphism (AFLP) analyses was carried out on subset fungal isolates. Determination...
This is the first study to isolate, identify and characterize Streptococcus iniae as causative disease agent in two tilapia (Oreochromis aureus) populations. The populations were geographically isolated, of distinct origins, did not share water sources. Affected fish showed various external (e.g., exophthalmia cachexia, among others) internal granulomatous septicaemia interstitial nephritis, signs. All organ samples produced pure cultures, which (one from each farm, termed S-1 S-2) subjected...
A fast, reproducible, and efficient transformation procedure employing Agrobacterium rhizogenes was developed for Phaseolus vulgaris L. wild accessions, landraces, cultivars three other species belonging to the genus Phaseolus: P. coccineus, lunatus, acutifolius. Induced hairy roots are robust grow quickly. The frequency is between 75 90% based on 35-S promoter-driven green fluorescent protein β-glu-curonidase expression reporter constructs. When inoculated with Rhizobium tropici, transgenic...
We investigate the geographic pattern of adaptation a fungal parasite, Colletotrichum lindemuthianum, on two host species, Phaseolus vulgaris and P. coccineus for parasite fitness traits: infectivity (ability to attack individual) aggressivity (degree sporulation leaf surface damage). Using cross-inoculation experiment, we show specialization fungus its species origin both traits even when fungi, which originated from hosts growing in sympatry, were tested sympatric populations. Within...
To detect early changes in the metabolic profile of pregnant ewes subject to acute feed restriction at 130 days gestation, and establish indicators risk for ovine pregnancy toxaemia (OPT) diagnostic purposes.Twenty Corriedale with known mating dates, carrying a single fetus, were used. Ewes maintained on meadow grasslands gestation randomly divided two groups 10 ewes. The control group had ad libitum access pasture. restricted subjected an maximum 144 hours (6 days), free water. From start...
Ovine pregnancy toxaemia is a common metabolic disorder of ewes due to increased foetal energy requirements in late pregnancy. This pathology condition characterized by hypoglycaemia and hyperketonaemia resulting the inability animal maintain an adequate balance. The response treatment effective, if it started early stages disease, when irreversible neurological injuries have not yet been established. aim was evaluate three therapeutic alternatives effectively reverse disease process its...
Since its inception in 1980, the breeding project for adaptation to drought has been based on crop phenology (escape or matching between biological cycle and water availability), seed yield multilocational trials under stress conditions. For evaluation, bean genotypes were grouped basis of similar growth habits phenology. Selection segregating families according was postponed up until F4 generation subsequent ones, using incomplete block designs. early generations moderate high heretability...
The objective of this study was to obtain a phenotypic and genotypic profile Salmonella enterica including multidrug‐resistant (MDR) isolates from food‐producing animals clinical isolates, as well their genetic relatedness in two different States Mexico (Jalisco State Mexico). A total 243 were evaluated terms antimicrobial resistance (AMR) related genes through disk diffusion method PCR respectively; we found 16 MDR all them harbouring the blaCMY gene but not qnr genes, these represent less...
Phaseolus vulgaris line A193 has been shown to be widely resistant Colletotrichum lindemuthianum, including race 1472, one of the most virulent races C. lindemuthianum characterized. Resistance 1472 in P. was investigated segregating F 2 and 2.3 populations from a cross between Flor de Mayo Bajio (a commercial cultivar highly susceptible lindemuthianum). determined conditioned by single dominant gene. Inoculation crosses cultivars Michigan Dark Red Kidney Perry Marrow with suggest that...
Corynebacterium xerosis is a commensal organism found in skin and mucous membranes of humans. It considered an unusual pathogen, it rarely human animal clinical samples. Here we describe the isolation C. from 4-months-old Pelifolk lamb located Tesistán, central western Mexico. This microorganism should be for differential diagnosis cutaneous abscessed lesions sheep, as represents zoonotic risk factor infection sheep farms. The exhibited hard-consistency, 5 cm diameter abscess, without...
Polyunsaturated fatty acid (PUFA) deposition in lambs’ muscles could be influenced by their mothers’ diet. The aim was to study the profile of acids muscle lambs from ewes supplemented with different sources PUFA achieve a healthier meat for consumer. On day 100 gestation, pregnant grazed on natural grass were divided into three groups (n = 20) and PUFA: Group A: 700 g ration rich PUFA, B: sheep + 20 mL fish oil C: same ration. After parturition, each group subdivided: ten continued diet...
In the last decade, harmful use of dioxin has been demonstrated in human health and whole environment. It is well known among scientists that 2, 3, 7, 8-tetrachloro dibenzo-p-dioxin (TCDD) an environmental pollutant causes endocrine disruption, which male reproductive toxicity.The objective present study was to evaluate toxicity effect low doses TCDD CD1 mice.Three concentrations (0.375, 0.75, 1.5 mg / kg) were analyzed effects on spermatozoa evaluated 10 days after oral administration...
The venom of Centruroides limpidus (Cll) is a mixture pharmacologically active principles. most important these are toxic proteins that interact both selectively and specifically with different cellular targets such as ion channels. Recently, anticancer properties the from other scorpion species have been described. Studies in vitro shown induces cell death, inhibits proliferation triggers apoptotic pathway cancer lines. Herein, after treating human cervical adenocarcinoma (HeLa) cells Cll...
PCR amplification and sequencing of Trypanosoma cruzi (T. cruzi) spliced-leader intergenic region the mini-exon gene (SL-IR) fragment was performed on intestinal tissue fecal content DNA extracted from 19 Meccus pallidipennis (M. pallidipennis) specimens collected in southern State Mexico. sequence analysis 49 bp T. SL-IR showed that all samples corresponded to haplotype TcIa, them were identical GenBank JQ028863. When extending whole 256 amplified SL-IR, we found six sequences with a C...
