Molecular identification of blaTEM and blaCTX-M genes in multidrug-resistant Escherichia coli found in milk samples from dairy cattle farms in Tulungagung, Indonesia

“…Another study of faecal samples from cattle suffering diarrhoea found 21 (77.8%) and 28 (63.6%) MDR isolates of E. coli from samples of dairy cows and beef cattle, respectively ( 31 ). Escherichia coli isolates were tested in Ethiopia and 27 (100%) were MDR, 188 (100%) E. coli isolates in Nigeria were reported to be resistant to three to seven different classes of antibiotics, and 76 (53%) E. coli isolates demonstrated multidrug resistance in Vietnam ( 4 , 7 , 14 ). A discovery of MDR E. coli was made in milk, perhaps because of improper or excessive antibiotic use in treating infectious diseases in dairy cattle, environmental and farm personnel contamination transferred during the milking process, or the free movement of the animal ( 25 ).…”

Imprinting of nanoparticles in thin films: Quo Vadis?

“…72,73 Moreover, multidrugresistant bacteria are becoming a serious threat to public health in many elds spanning from foodborne to water safety. [74][75][76][77] The urge for new and rapid detection methods for bacteria, viruses, and large-scale bio entities has been developed due to the weaknesses of the classical methods mentioned above. Generally, ensuring these techniques' selectivity, namely, their ability to recognize pathogens, has relied on natural biological-recognition elements, i.e., receptors, such as antibodies, aptamers, and peptides.…”

Prevalence, molecular characterization of integrons and its associated gene cassettes in Klebsiella pneumoniae and K. oxytoca recovered from diverse environmental matrices

“…Although the main focus of detecting integrons and their GCs was within the clinical environment, they have also been identified in several bacterial species from various environmental sources 14 , 22 , 29 . In Africa, some studies have reported the detection of GCs within the environment 31 , 32 however, no studies exist on integron characterization in Klebsiella spp. from environmental sources in the Eastern Cape Province (ECP) in South Africa.…”
