This study was aimed to detect the prevalence of Pseudomonas aeruginosa in milk (n=125) samples which were collected from local vendors, private dairy farms in and around Tirupati. Pre-enrichment was done by taking 10ml of each sample and inoculated in 90 ml of Tryptone Soya broth and incubated at 37 0 C for 24hrs. A loopful of culture was taken from broth and streaked on nutrient agar and Cetrimide agar plates and incubated at 37 0 C for 24hrs which were further confirmed by biochemical tests. The nineteen positive samples for P.aeruginosa were further tested for antimicrobial susceptibility which has shown multi drug resistant ranging from four to twelve antimicrobials and Multiple Antibiotic Resistance (MAR) index ranges from 0.33 to 1.The isolates of P.aeruginosain the present study are highlyresistant to ampicillin, penicillin, and oxacillin (100%) and maximum sensitive to Vancomycin (5.3%) followed by Tetracycline (10.5%).
of the main sources of protein but if contaminated by toxic heavy metals due to industrial waste, geochemical structures and agricultural activities is a serious problem for environmental and human health Singh et al., (2007).Apart from these, chickens are also exposed to heavy metals by feed intake. Poultry could take up heavy metal from different sources, especially via nutrition. Therefore, metal residues may concentrate in their meat, and
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
