R factor Rms 151 is an fi+ R factor and belongs to a incompatibility group FII. It carries the genes governing resistance to various aminoglycoside antibiotics, i.e., kanamycin (KM), lividomycin (LV), gentamicin C complex (GM), and 3',4'-dideoxykanamycin B (DKB), in addition to those governing to tetracycline (TC), chloramphenicol (CM), sulfanilamide (SA), and ampicillin (APC). Electron microscopy observation disclosed that the Rms151 deoxyribonucleic acid was a circular form with length of 31.2 mum. A probable circular genetic map of Rms151 was proposed by genetic and biochemical studies, the genes being in the order of -tet-tra-amp-aad-sul-aph-cml-, in which aad and aph confer resistance to KM.GM.DKB by adenylytransferase or resistance to KM.LV by phosphotransferase, respectively.

Splenic abscesses are caused by Staphylococcus aureus, Streptococcus and bacteria belonging to the family Enterobacteriaceae. We report a case of splenic abscess caused by an unusual serotype of Salmonella. A 55 year old man was admitted with complaints of fever and abdominal pain. On the basis of clinical findings and laboratory reports, a diagnosis of chronic myeloid leukemia was made. Ultrasonography of the abdomen revealed a single large cystic lesion in the spleen. Percutaneous drainage of the abscess was carried out. Salmonella enterica serotype Worthington was isolated from a pus sample taken from the abscess. The isolate was resistant to ampicillin, gentamicin, cefotaxime, chloramphenicol and tetracycline, and sensitive to amikacin and norfloxacin. Serotype Worthington is an emerging pathogen. This is the first report of isolation of this serotype from a splenic abscess. In seriously ill patients, such infections should be treated with a combination of antibiotics to circumvent problems with multidrug resistance.

From stool specimens of 118 healthy children's (1-14 years) in Portugal 92 E. coli and 101 Enterococcu s spp. strains have been isolated. Almost half (40.2%) of the E. coli isolates were resistant to ampicillin, 25.0% were resistant to tetracycline and 26.1% were resistant to streptomycin. Resistance genes detected by specific PCR included bla(TEM) and/or bla(SHV) and/or bla(CTX-M) (33 of 37 ampicillin and/or cefotaxime resistant isolates), tet (A) and/or tet (B) (16 of 23 tetracycline-resistant isolates), aad A (19 of 24 streptomycin-resistant isolates), cml A (in the two chloramphenicol-resistant isolates), aac (3)-II with/without aac (3)-IV (in the four gentamicin-resistant isolates), sul 1 and/or sul 2 and/or sul 3 (in all trimethoprim/sulfamethoxazole resistant isolates). The majority of the resistant E. coli isolates (69.1%) belonged to phylogenetic group B2. Of the enterococci isolates E. faecium (n = 53), E. faecalis (n = 41), E. hirae (n = 4) and E. durans (n = 3) more than one-fourth (28.7%) of the isolates were resistant to tetracycline; 21.8% were resistant to erythromycin and 8.9% were resistant to kanamycin. Resistance genes detected by PCR in enterococci included aph (3)'-IIIa (in all kanamycin-resistant isolates), aac (6') (in all gentamicin-resistant isolates), tet (M) and/or tet (L) (26 of 29 tetracycline-resistant isolates), erm (B) (17 of 22 erythromycin-resistant isolates). This survey showed that faecal bacteria such as E. coli and enterococci of healthy growing children's could be a reservoir of antimicrobial resistance genes.

Mastitis is one of the most important diseases in dairy cows throughout the world and is responsible for significant economic losses to the dairy industry. This study was performed to characterize the genetic basis of drug resistance in Escherichia coli isolated from cases of clinical and sub-clinical bovine mastitis. A total of 224 California mastitis test (CMT)-positive milk samples were collected from December 2015 to April 2016 to characterize the phenotypic and genetic basis of antimicrobial resistance in E. coli isolated from raw milk from dairy farms found in Burayu, Sebeta, and Holeta areas of Ethiopia. The prevalence of E. coli was 7.1% (16) and both phenotypic and molecular techniques were used to identify E. coli antimicrobial susceptibility trait. The most commonly observed phenotypic resistance was against ampicillin (68.7%), sulphamethazole-trimethoprim (50%), and streptomycin (25%). Multidrug resistance phenotypes were found in 11 of 16 (68.7%) of E. coli isolates. Tetracycline (tet (A)) and chloramphenicol (cml (A)) genes were the most predominant encoding resistance genes identified (50%) each, followed by gentamycin resistance encoding gene (aac (3)-IV) (37.5%). Overall, 11 (68.7%) of the isolates had multidrug resistance genes responsible to two or more classes of antibiotics. The most common pattern detected was cml (A) and tet (A) together 37.5% followed by aac (3)-IV and tet (A) 25%. The current study indicated that raw milk could be regarded as critical source of antibiotic-resistant pathogenic E. coli.
