Pinworm ova were discovered on lesser hedgehog tenrec (Echinops telfairi) fecal exams. Ova passthrough pseudoparasite pinworms originating from feeder roaches (Blaptica dubia). Roaches maintained as a colony and offered to tenrecs portion of their diet. Pinworms identified Leidynema appendiculata. This study aimed determine if these could be eliminated the roaches. randomly assigned into groups...
Escherichia coli (E. coli) O157:H7 is a Shiga toxin producing member of enterohemorrhagic E. coli (STEC). It is a major foodborne bacterial pathogen, which was first associated with human illness during an outbreak of hemorrhagic colitis in 1982, and has been listed by the Centers for Disease Control and Prevention as a national notifiable disease since 1994. This bacterium has been estimated t...
Premature spoilage and varying product quality due to microbial contamination still constitute major problems in the production of microfiltered and pasteurized extended shelf life (ESL) milk. Spoilage-associated bacteria may enter the product either as part of the raw milk microbiota or as recontaminants in the dairy plant. To identify spoilage-inducing bacteria and their routes of entry, we a...
Groundwater serves as a major drinking water source due to inadequate piped supplies in Indonesia. To eliminate the health risks associated with groundwater consumption, boiling appears most suitable and cost-effective treatment technique widely practiced Despite efforts, inappropriate storage handling practices pose higher risk of recontamination after treatment. The objective this study was a...
The recent COVID-19 pandemic and the accelerating rise of deaths associated with antibiotic-resistant bacterial strains have highlighted global health economic threats caused by super spreading pathogens. A major route transmission for pathogens is via surfaces contaminated touch or droplets generated sneezing coughing. Current surface disinfection strategies are having diminishing efficacy, du...
The use of conventional chemical disinfectants is a common practice in built environments and has drastically increased response to the COVID-19 pandemic. While effective for instantaneous disinfection, application indoor surfaces associated with recontamination prone select antimicrobial-resistant pathogens. In contrast, probiotic-based sanitation (PBS) relies on premise that probiotic bacteri...
Contamination sites of Pseudomonas fluorescenswere traced in the production line for milk pasteurization in a large dairy plant in Shiraz, Iran. Samples of raw and pasteurized milk were collected at six sites along the line. All milk samples were incubated at 7°C until the aerobic plate count had reached 10 6 -10 7 cfu mL-1. Colonies were picked randomly and identified. No growth of gram negati...
