Chimeric proteins of Mycoplasma hyopneumoniae as vaccine and preclinical model for immunological evaluation.

Mycoplasma hyopneumoniae (M. hyopneumoniae) is a primary agent of porcine enzootic pneumonia, a disease that causes significant economic losses to pig farming worldwide. Commercial vaccines induce partial protection, evidencing the need for a new vaccine against M.

Review of methods for detection and characterization of non-tuberculous mycobacteria in aquatic organisms.

Mycobacteriosis is an emerging and often lethal disease of aquatic organisms caused by several non-tuberculous mycobacteria (NTM) species. Early diagnosis of mycobacteriosis in aquaculture and aquatic settings is critical; however, clinical diagnoses and laboratory detection are challenging, and the available literature is scarce. In an attempt to fill the gap, here we review the most relevant approaches to detect and characterize mycobacteria in clinical specimens of aquatic organisms.

Inhibition of invasion into bovine mammary epithelial cells previously infected by subsp. .

The coinfection process of , an etiological agent of clinical mastitis and subsp. (MAP), a non-mastitic etiological agent in the bovine mammary gland is not fully known. Verify the ability of MAP to interfere with the invasion and translocation of in bovine mammary epithelial cell line (MAC-T).

Biofilm formation on biotic and abiotic surfaces in the presence of antimicrobials by Escherichia coli Isolates from cases of bovine mastitis.

Escherichia coli is a highly adaptive microorganism, and its ability to form biofilms under certain conditions can be critical for antimicrobial resistance. The adhesion of four E. coli isolates from bovine mastitis to bovine mammary alveolar (MAC-T) cells, biofilm production on a polystyrene surface, and the expression profiles of the genes fliC, csgA, fimA, and luxS in the presence of enrofloxacin, gentamicin, co-trimoxazole, and ampicillin at half of the MIC were investigated.

Escherichia coli from clinical mastitis: serotypes and virulence factors.

In the current study, the virulence factors in Escherichia coli isolates from bovine mastitis were investigated, and the connection between these factors and infection was evaluated using phenotypic and genotypic analyses. Twenty-seven E. coli isolates were analyzed, and 2 were shown to produce verotoxin.

Multidrug efflux systems in Escherichia coli and Enterobacter cloacae obtained from wholesome broiler carcasses.

Members of the Enterobacteriaceae family are present in the intestines of man and animals as commensals or are important disease causing agents. Bacteria bearing multidrug efflux systems (MDR) are able to survive adverse ecological niches. Multiresistant Escherichia coli and Enterobacter cloacae isolates from wholesome broiler carcasses were investigated for the presence of MDR.
