| The aim was to detect the presence of polymorphisms at exons 1, 2, 3 and 4 of the Spi2 gene, and evaluate a possible association between them and recurrent airway obstruction (RAO) or inflammatory airway disease (IAD) in thoroughbred horses, through single-strand conformational-polymorphism (SSCP) screening. Although polymorphism was not detected in exons 1, 2 and 3, three alleles and six genotypes were identified in exon 4. The frequencies of allele A (0.6388) and genotype AA (0.3888) were higher in horses affected by RAO, although no association was found between polymorphism and horses with either RAO or IAD. |

| ABSTRACT Respiratory diseases are common in young horses but little is known about such infections in mule foals. This study aimed to characterize Escherichia coli and Klebsiella sp. isolated from tracheal wash (TW) and fecal samples (FS) of mule foals, with or without cytological evidence of respiratory disease. Strains were analyzed against 13 antimicrobials, for presence of Extended spectrum beta-lactamase (ESBL), and virulence genes. Phylogrouping and Randomic (RAPD)-PCR profiles were used to evaluate their genetic relatedness. E. coli strains from TW and FS showed greatest resistance to tetracycline, while Klebsiella strains were mainly resistant to ampicillin; multidrug resistance and ESBL production were also detected. The blaCTX gene prevailed... |
