Synthetic dye is produced by chemical compound that can be harmful to living microorganisms and human. Textile dye industry is inadequate dye effluent to the environment that can lead to water pollution. Therefore, the  releasing dye effluent should be minimized. Eggshell and peanut shell adsorbent are recycled from solid agro-waste and household food waste. They are wildly used in adsorption process to dye effluent before releasing into natural water bodies. However, the toxic reduction of dye after dye removal is unknown. The aim of this study was to investigate the toxicity of eosin dye and its removal by adsorbent. Moreover, the cytotoxicity of dye is evaluated by brine shrimp lethality bioassay. The results showed that the dye after removal by eggshell had the lower mortality rate when compared to those of eosin dye and penut shell adsorption. The histopathological lesions such as abnormal appearance of enterocyte, blebing cell and coagulation necrosis were found. Therefore, these bio-natural adsorbents might be the alternative substances for the adsorption process in wastewater treatment and they might decrease the toxicity of dye pollution.

Acinetobacter is a bacteria found in the environment and clinical specimens, causing nosocomial infection and antimicrobial resistance (AMR) threats. This study examined the prevalence, species, and AMR characteristics of Acinetobacter isolated from surgical practice and the laboratory dog husbandry room environments (n = 235) at Rajamangala University of Technology Tawan-ok veterinary hospital during 2018-2019. The prevalence of Acinetobacter in the laboratory dog husbandry room and veterinary belongings were 2.55% and 0.43%, respectively. Species determination was Acinetobacter hemolyticus (2.1%) and Acinetobacter baumannii (0.4%) from environments in the laboratory dog husbandry room, and Acinetobacter junii (0.4%) from the shoes used in the surgical practice room. AMR was observed in both study environments and the specimens sent to the Veterinary Diagnostic Center. These isolates had a high resistant percentage to amoxicillin-clavulanic acid (84.62%), sulfamethoxazole-trimethoprim (61.54%), and cephalexin (53.85%) but were susceptible to imipenem. Compared to the isolates recovered from the clinical specimens, most isolates derived from environments exhibited multidrug resistance and shared correlated resistance patterns. These results highlight the need for sanitization in the dog husbandry room. Furthermore, the AMR results can be used as a preliminary baseline for studying AMR Acinetobacter contamination in animals and their environments.
