Abstract

The aims of this study were to investigate the effect of agricultural residues on reducing cadmium uptake in rice plants. The rice plants growing on no cadmium/free cadmium soils (N), Cd soils (Cds), and Cd soils each amended with 1% w/w of coir pith (CP), coir pith modified with sodium hydroxide (CPm) and corncob (CC) under high cadmium contaminated soil with an average 145 mg Cd kg-1 soil were investigated. The results showed that the cumulative transpiration of rice grown in various treatments under high cadmium contaminated soil followed the order: Cds > CPm ≥ CP ≥ CC. These transpirations directly influenced cadmium accumulation in shoots and husks of rice plants. The CC and CP seemed to work to reduce the cadmium uptake by rice plants indicated by accumulated cadmium in the husk that were 2.47 and 7.38 mg Cd kg-1 dry weight, respectively. Overall, transpiration tended to drive cadmium accumulation in plants for rice grown in high cadmium contaminated soil. The more that plants uptake cadmium, the lower cadmium that remains in the soil. Keywords: Transpiration, Cadmium Uptake, Rice plant, Agricultural Residues

Abstract

This study was conducted in Malang, Indonesia, to assess the prevalence and antibiotic susceptibility of Pasteurella multocida in cattle exhibiting clinical signs of respiratory disease. Nasal and tracheal swabs were collected from 50 cattle across multiple farms and tested for P. multocida. The isolates were identified through colony morphology, Gram staining, and biochemical tests, with 4 out of 50 samples (8%) testing positive for P. multocida. Antibiotic susceptibility was determined using the disk diffusion method, involving seven antibiotics commonly used in veterinary practice. Results showed that 75% of the isolates were sensitive to ceftriaxone, while amoxicillin-clavulanic acid was effective in 50% of cases. However, all isolates demonstrated resistance to erythromycin and tetracycline. These findings emphasize the importance of susceptibility testing to guide appropriate antibiotic therapy and prevent the development of resistance. Further research is necessary to monitor resistance patterns and improve treatment strategies for pasteurellosis in cattle.
