| potential use of bacillus thuringiensis bacteriocins to control antibiotic-resistant bacteria associated with mastitis in dairy goats. | mastitis caused by microbial infections in dairy goats reduces milk yield, modifies milk composition, and potentially contributes to morbidity in herds and consumers of dairy products. microorganisms associated with mastitis in dairy goats are commonly controlled with antibiotics, but it is known that continued use of these chemical agents promotes antibiotic resistance among bacterial populations. recently, it has been shown that bacteriocins of bacillus thuringiensis inhibit growth of food-bor ... | 2016 | 26022411 |
| molecular detection and sensitivity to antibiotics and bacteriocins of pathogens isolated from bovine mastitis in family dairy herds of central mexico. | thirty-two farms (n = 535 cows) located in the state of guanajuato, mexico, were sampled. pathogens from bovine subclinical mastitis (scm) and clinical mastitis (clm) were identified by 16s rdna and the sensitivity to both antibiotics and bacteriocins of bacillus thuringiensis was tested. forty-six milk samples were selected for their positive california mastitis test (cmt) (≥3) and any abnormality in the udder or milk. the frequency of scm and clm was 39.1% and 9.3%, respectively. averages for ... | 2015 | 25815326 |
| differences in susceptibility and physiological fitness of mexican field trichoplusia ni strains exposed to bacillus thuringiensis. | the use of different commercial bacillus thuringiensis (bt) products in the bajio guanajuatense area in mexico began 12 yr ago, and resistance to bt in this area has been reported for plutella xylostella (l.) the current study provides a baseline response and resistance potential to bt in field and laboratory strains of bajio trichoplusia ni (hübner). differences in susceptibility to bt among t. ni populations were observed. t. ni neonates collected in romita, guanajuato, were more susceptible t ... | 2006 | 16813334 |
