This study evaluates the immunological response following weekly 2h infusions of recombinant human N-acetylgalactosamine 4-sulfatase (rh4S) in Mucopolysaccharidosis VI (MPS VI) cats. The results of three trials (Trial "A": 9 month duration with onset at 3-5 months of age, n = 5; and Trials "B" and "C": 6 month duration starting at birth, n = 9) were compared. No detrimental effects were noted throughout Trials B and C. Temporary hypersensitivity reactions (e.g., vomiting, diarrhoea) occurred in four cats in Trial A and were alleviated by increasing the dose of antihistamine premedication and the duration of infusion. All cats in Trial A developed antibodies to rh4S (range of final titres: 1041-134,931). All cats treated from birth showed negligible titres (range: < 50-598). In vitro inhibition of rh4S activity (up to 47%) was demonstrated with plasma from four cats with elevated titres. Significant reduction of urinary glycosaminoglycan concentration in all cats indicated the ability of rh4S to metabolize stored substrates regardless of the presence of circulating antibodies. Similarly, lysosomal storage in reticuloendothelial cells and fibroblasts of kidney interstistium, dura and skin was reduced in all cats irrespective of their antibody titre although cats with elevated titre had less beneficial effect on cardiovascular tissues (aorta smooth muscle cells, heart valve fibroblasts). Overall improvement in the disease condition (at physical, neurological, and skeletal levels) was most pronounced for cats treated from birth compared with cats treated at a later age.

Aeromonas are bacteria widely distributed in the environment, and some species are able to cause infections in humans, of which diarrhea is the most common. The objective of this study was to evaluate the presence of virulence and antimicrobial resistance associated characteristics in A. veronii biovar sobria strain 312M isolated from diarrheal stools. For this, the genome sequencing and phenotypical tests were performed. The draft genome annotation revealed several complete pathways associated with carbon metabolism and a mucin-desulfating sulfatase which may contribute to intestine colonization, and a large number of virulence-associated genes encoding structures associated with adhesion, toxins, and secretion systems. The strain exhibited swimming and swarming motility, biofilm formation, and hemolytic activity. It was resistant to ampicillin, ampicillin/sulbactam, and amoxicillin-clavulanic acid. Although a cphA gene encoding a narrow-spectrum carbapenase was identified in the strain genome, no carbapenemase activity was detected in the antimicrobial susceptibility test. When compared with other A. veronii with complete genomes, the main differences in virulence characteristics are related to lateral flagella and type III and VI secretion systems; the antimicrobial resistance spectrum also varied among strains. The results indicated that A. veronii biovar sobria 312M presents high virulence potential and resistance to limited classes of antimicrobials.
