Antibiotics susceptibility of some Bacillus strains isolated in the ground and rainwater in urbanized area in Cameroon (Central Africa), and potential impact of the season change

This study assessed the antibiotics susceptibility of Bacillus cereus, B. thuringiensis and subtilis strains isolated in wells rainwater samples Yaounde (Cameroon). Water were collected monthly during a long dry season (LDS), short (SDS), rainy (LRS) (SRS), LRS SRS for rainwater. The considered included Imipenem, Amikacin, Gentamycin, Ciprofloxacin, Ofloxacin, Sulfamethazol, Tetracycline. With from groundwater, antibiotic inhibition diameters varied 9.13 mm (Sulfametazole SDS) to 32.78 (Imipenem LDS) with thuringiensis, 8.2 35.25 5.05 (Ofloxacin LRS) 29.25 subtilis. those rainwater, they 4.55 25.65mm 2.13 20.05mm SRS) 5.03 (Gentamicin 25.15mm (Tetracycline multiresistant majority antibiotics. most significantly one another (p
