Multi-virulence of carried by chicken meat in Brazil.

is the most frequent cause of bacterial gastroenteritis; therefore, the characteristics of its epidemiology must be continuously investigated to support possible mitigating measures. This is particularly important when evaluating representative strains from the world's leading chicken meat exporter, Brazil. We evaluated a panel of 14 virulence genes in 359 strains of isolated from chilled broiler carcasses in Brazil.

Phylogeny and Virulence Factors of Isolated from Dogs with Pyometra.

We aimed to investigate the occurrence, phylogeny, and virulence of in the uterine contents and urine of female dogs with pyometra, through the presence of virulence genes and their genetic similarity. Uterine secretions and urine samples from 52 female dogs with pyometra were collected and cultured. Strains identified as from 25 uterine and 7 urine samples were tested for virulence genes by PCR.

A Ternary Copper (II) Complex with 4-Fluorophenoxyacetic Acid Hydrazide in Combination with Antibiotics Exhibits Positive Synergistic Effect against Typhimurium.

spp. continues to figure prominently in world epidemiological registries as one of the leading causes of bacterial foodborne disease. We characterised 43 Brazilian lineages of Typhimurium (ST) strains, characterized drug resistance patterns, tested copper (II) complex as control options, and proposed effective antimicrobial measures.

Tongue nodules in an atypical canine leishmaniasis in Brazil.

We aimed to report a case of canine leishmaniasis with the only visible clinical sign being the presence of nodules in the lateral region of the tongue. The bitch was treated for a mandibular fracture, when multiple small nodules were observed on the tongue. We identify nodular glossitis with the presence of structures compatible with amastigote forms of Leishmania.

Molecular Characterization and Survive Abilities of Heidelberg Strains of Poultry Origin in Brazil.

The aim of the study was to evaluate the genotypic and phenotypic characteristics of 20 strains of Heidelberg (H) isolated from broilers produced in southern Brazil. The similarity and presence of genetic determinants linked to virulence, antimicrobial resistance, biofilm formation, and -predicted metabolic interactions revealed this serovar as a threat to public health. The presence of the , , , , , and genes was detected in 100% of the strains and the gene in 70% of them.

Genotypical Relationship Between Human and Poultry Strains of Campylobacter jejuni.

This study aimed to compare the genotype diversity of C. jejuni isolates. From the total of 64 C.

Serovar Minnesota Biofilms, Susceptibility to Biocides, and Molecular Characterization.

The presence of virulence genes, phylogenetic relationships, biofilm formation index (BFI), and ultrastructure in Minnesota at different temperatures (4, 25, and 36 °C) were analyzed. In addition, the ability of biocidal agents (chlorhexidine1%, sodium hypochlorite 1%, and peracetic acid 0.8%) to inhibit biofilms formed by 20 strains isolated from broiler slaughter plants from two Brazilian companies in 2009, 2010, and 2014 was determined.

Antibiotic Resistance in the Alternative Lifestyles of .

is the main pathogen identified in cases of foodborne gastroenteritis worldwide. Its importance in poultry production and public health is highlighted due to the growing antimicrobial resistance. Our study comparatively investigated the effect of five different classes of antimicrobials on the planktonic and biofilm forms of 35 strains of with high phylogenetic distinction in 30 of them.

Nanocarriers From Natural Lipids With Activity Against .

(CJ) is the most prevalent zoonotic pathogen of chicken meat and related products, which may lead to gastroenteritis and autoimmune diseases in humans. Although controlling this bacterium is important, CJ strains resistance against traditional antibiotic therapy has been increased. Vegetable oils and fats are natural biomaterials explored since the Ancient times, due to their therapeutic properties.

Hybrid Pectin-Liposome Formulation against Multi-Resistant Bacterial Strains.

This work describes the development of a gastroresistant antimicrobial formulation composed of two carriers, pectin and liposomes, intended to improve the efficiency of norfloxacin (NOR) against multi-resistant bacterial strains. The formulations showed physicochemical stability for 180 days (4 °C) in terms of size, polydispersity, and zeta potential of the vesicles, prolonging the in vitro release of NOR for 11 h. The hybrid nanocarriers improved the in vitro antimicrobial activity against different multidrug-resistant bacterial strains, such as sp.

Evolution of Campylobacter jejuni of poultry origin in Brazil.

Campylobacter jejuni is the most common pathogen associated with foodborne diseases. Persistent presence of this pathogen contaminating the environment in slaughterhouses and chicken products have been reported worldwide. Although many efforts have been employed for reducing C.

Spread of the serotypes and antimicrobial resistance in strains of Salmonella spp. isolated from broiler.

Serotypes and antimicrobial susceptibility of Salmonella's isolates from broiler production chain were determined. A total of 239 isolated strains from chicken, carcasses, breeding environments, and slaughter was analyzed by disk diffusion test, in the period of 2009 to 2010. For antibiotics with a high number of resistant strains, the minimal inhibitory concentration (MIC) was performed.

Intrinsic and Extrinsic Aspects on Biofilms.

Biofilm represents a way of life that allows greater survival of microorganisms in hostile habitats. is able to form biofilms and on surfaces at several points in the poultry production chain. Genetic determinants related to their formation are expressed differently between strains and external conditions are decisive in this respect.
