The objective of this study was to assess the infection rate of Anaplasma marginale in cattle by Rhipicephalus microplus . Two experiments were conducted for this purpose. Experiment 1 evaluated the infection rate by the intrastadial and transstadial routes. Calves naturally infected with A. marginale were infested with R. microplus and were called “positive with ticks” (PWT). These PWT animals were housed together with A. mar...

The purpose of this research was to assess the effectiveness of a combination of monoterpenes (thymol and carvacrol) in treating juvenile Nile tilapia ( Oreochromis niloticus ) infected with Edwardsiella tarda as a potential substitute for the antibiotic oxytetracycline. The study utilised different concentrations of the monoterpenes blend (MTs): 0.4, 0.6 and 0.8 g kg −1 of feed. A negative control group received a diet withou...

Aquaculture is a rapidly growing industry that supplies fish for global consumption. However, the intensive production practices have resulted in disease outbreaks, largely driven by the misuse of antibiotics. Natural alternatives, such as monoterpenes, which are biocompounds derived from essential oils obtained from plants like thyme and oregano, are being investigated for their antimicrobial properties. Research has shown th...
