Can I find out what resistance bacteria has based on strain? where do I look for that info?
If database and literature searches fail, you can plug the GenBank accession numbers for your genomes into the CARD Resistance Gene Identifier. It takes either protein or nucleotide sequences, though nucleotide seqs. undergo ORF calling first. For example, plugging in NZ_CP009072.1 for E. coli ATCC 25922 gives 7 perfect hits to known antibiotic resistance genes. Granted, carrying the genetic determinants of resistance is different from phenotypic resistance, but it's a place to start.
