The gene product of open reading frame 5 (p25) porcine reproductive and respiratory syndrome (PRRS) virus has been expressed by coinfection culture cells with vaccinia expressing the T7 RNA polymerase a recombinant encoding under promoter encephalomyocarditis internal ribosome entry site. In spite reported efficiency expression system, very poor accumulation p25 protein was observed strong cytotoxicity produced in doubly infected cells. This cell toxicity shown to occur induction apoptosis,...
La rápida evolución de la tecnología ha transformado significativamente los procesos adquisición y enseñanza lenguas, representando un área interés creciente para investigadores educadores. Este estudio aborda relevancia comprender cómo las herramientas tecnológicas influyen en el aprendizaje lingüístico, considerando su potencial mejorar eficacia educativa superar barreras tradicionales. El objetivo principal investigación es analizar manera sistemática impacto identificando tendencias,...
The rates of mutation to the mar (monoclonal antibody-resistant) genotype individual influenza virus plaque isolates, obtained from a stock generated after two successive cloning steps, have been determined by fluctuation test. When random sample 60 clones was analyzed, 7 contained proportion mutants significantly higher than average, and among them, 2 showed rate three times average value for population when hemagglutinin-specific monoclonal antibody 2G10 used. In order look with rates,...
Twenty‐five gilts without measurable serum antibody titres to porcine reproductive and respiratory syndrome virus (PRRsv) were identified 16 inoculated with PRRSV at seven, 14 or 21 days of gestation killed 20 22 later determine the effect on their embryos. The remaining nine not exposed PRRSV, but same stages gestation. gults observed for clinical signs infection embryos tested PRRv homologous antibodies. was demonstrated by re‐isolation its detection reverse transcriptase polymerase chain...
Cryptosporidium parvum and Blastocystis hominis are foodborne parasites known for causing diarrhea. They accumulate in mussels grown on contaminated water bodies, due to the discharge of treated sewage from treatment plants (STP). Despite this, some countries like Chile do not include these control or monitoring water. The objective this research was evaluate contamination C. parvum. B. (disinfected by chlorination) Cholga a touristic rural cove bay Concepción. commercial stores sample were...
A total of 522 Streptococcus suis isolates were recovered from the tonsils slaughtered pigs by culturing on media containing different specific antisera. The serogroup reactions determined coagglutination. most frequently isolated serotype was 4 (representing 28.7% isolates), followed 3 (24.9%) and 2 (22.6%). Typable examined growth in 6.5% NaCl, amylase activity, acetoin production, susceptibility to optochin production acid mannitol, melibiose, raffinose, salicin, sorbitol trehalose....
Aims: This project investigated the utility of HP selective medium to isolate H. pylori cells from seawater and marine molluscs. Methods Results: Nested-PCR was performed reveal presence Helicobacter genus. All samples were cultured in 16 cultures initially selected as putative Helicobacter. spp. DNA detected 9/16 three them had 99–100% homology based on 16S RNA gene sequence. isolation unsuccessful. On basis sequences contaminating organisms shown be Proteus mirabilis Vibrio cholerae....
Summary A total of 65 isolates Streptococcus suis was recovered from various tissues diseased pigs. Almost 96 % all these could be categorized as one capsular types 1 to 22 and 1/2. Capsular type 2 the most prevalent represented 53.8 isolates, followed by (9.2 %), 1/2 (7.7 %) 8 (4.6 %). Brain‐meninges, multiples lungs were source majority isolates. 37 S. mainly brain‐meninges, found in pure culture. The antimicrobial susceptibility pattern determined.
Pseudomonas aeruginosa is a prominent member of emerging waterborne pathogens. The environmental reservoirs multi-resistant phenotypes and other virulence factors in this bacterium are poorly understood. Our study aimed to determine the properties P. isolated from Roraima Sur Cave (RSC) waters at Guayana Highlands. Based on best identification species level by biochemical tests, 16S rRNA sequencing phylogenetic inferences, one RSC isolate named LG11 was characterized for comparison with...

A eutanásia em cães, gatos, peixes e baleias é um procedimento realizado quando esses animais enfrentam condições médicas irreversíveis que comprometem significativamente sua qualidade de vida ou estão sofrendo forma irreparável. No caso cães a considerada há doenças terminais lesões graves não podem ser tratadas eficaz, garantindo assim fim digno humanitário para o animal, evitando prolongar seu sofrimento. decisão realizar geralmente tomada pelo tutor consulta com veterinário, levando...
A encefalite do cão adulto é uma das apresentações clínicas da cinomose canina, doença viral altamente contagiosa que afeta o sistema nervoso central e periférico dos cães. Causada pelo vírus canina (CDV), família Paramyxoviridae pertence ao gênero Morbillivirus. Foi encaminhado à Clínica Veterinária, no mês de julho 2023 um macho, sem raça definida, com aproximadamente ano idade, sintomas compatíveis diagnóstico cinomose. O caso específico oferece perspectiva singular sobre a experiência...
