Effect of a probiotic mixture with lactic acid activity on productive and allometric indicators in broiler chickens.

Background And Aim: The feeding and sanitary conditions significantly influence the productivity of farm animals. This study aimed to assess the impact of a lactic acid-producing microbial additive on broiler chicken productivity.

Materials And Methods: A 42-day experimental period utilized 120 1-day-old Cobb 500 chicks with an average weight of 46 g.

Streptococcus agalactiae virulence factors isolated from bovine mastitis and antibiotic treatment response.

Aims: This study aims to characterize the virulence factors of Streptococcus agalactiae strains isolated from bovine mastitis and their potential association with the antibiotic treatment response.

Methods And Results: Four different profiles were identified among the 181 S. agalactiae strains using polymerase chain reaction, of which hyl B and cylE were found in 100% of the isolated strains, followed by cfb (99.

Evaluation of three proteins involved in the adhesion process as antigens for the detection of bovine intramammary infections.

. Fast and accurate diagnosis is one of the key strategies in the successful control of intramammary infections caused by . Immunoassays are one of the diagnostic tools that have been proposed for the detection of infection because they offer an advantage in terms of cost and are fast and easy to use compared to other diagnostic tests.

Urban versus Rural Prevalence of Intestinal Parasites Using Multi-Parallel qPCR in Colombia.

Stool samples from 122 children living in an urban slum (n = 72) and rural (n = 50) areas were analyzed using multi-parallel real-time quantitative PCR to determine intestinal prevalence parasites from two communities in Colombia. Findings indicated a prevalence of 86.1% Blastocystis spp.

Phenotypic Characterization and Whole Genome Analysis of a Strong Biofilm-Forming Strain Associated With Subclinical Bovine Mastitis in Colombia.

represent a serious threat to public health due to food safety, antibiotic resistance, and the potential zoonotic transmission of strains between dairy cattle and humans. Biofilm formation by results in chronicity of the infections which confers protection against the immune response and antibiotics. Likewise, biofilm allows the exchange of mobile genetic material among different strains through microbial interactions inside the matrix.

Metagenomic characterization of bacterial biofilm in four food processing plants in Colombia.

Bacteria inside biofilms are more persistent and resistant to stress conditions found in the production environment of food processing plants, thus representing a constant risk for product safety and quality. Therefore, the aim of this study was to characterize, using 16S rRNA sequencing, the bacterial communities from biofilms found in four food processing plants (P1, P2, P3, and P4). In total, 50 samples from these four processing plants were taken after cleaning and disinfection processes.

[Concordance between thick blood smear, immunochromatography and polymerase chain reaction for malaria diagnosis].

Introduction: The rapid and effective diagnosis of malaria is the determining condition for an appropriate treatment and control of the disease.

Objective: The sensitivity, specificity and the positive and negative predictive values were evaluated in cases of suspected malaria in Colombia in a comparison of a rapid diagnostic test. the PCR test and the thick blood smear-the traditional gold standard.
