Sarcocystosis is one of the important zoonotic parasitic diseases and commonly reported in buffaloes, cattle and pigs. Meat and meat products are the main sources of infection in human beings. The present study aimed to record the prevalence of Sarcocystosis in buffaloes during the time of slaughter. Out of 61 buffaloes slaughter for meat purpose, 38 showed the presence of macroscopic sarcocysts in different organs and they were in creamy colour lying parallel in between the muscle bundles. Distribution of the sarcocysts was noticed in the muscles of oesophagus, diaphragm, heart and base of the tongue. Microscopic examination of the stained impression smears collected from the mixed meat which is ready for sale from the 61 buffaloes, 52 were found positive for microscopic bradyzoites. In conclusion, Sarcocystis is more prevalent in buffaloes and diagnosis of the disease can be done by microscopic examination of the stained slide impression smears from the suspected meat along with the macroscopic examination of the muscles.
Contribution/ Originality
This study is one of the very few studies which have investigated the diagnosis of zoonotic disease in veterinary sciences. This study contributes in the existing literature on diagnosis of the Sarcocystosis in the mixed meat which is readily available for sale to the public and caution as a public health alert.

Aedes aegypti is primary vector of Zika virus, dengue, and chikungunya which go through four different stages of life cycle: Egg, Larva, Pupa, and Adult. The mosquito might be able to lay 100 eggs at a time. The eggs can hatch when there is water and submerged in the water, but it can survive without water almost to 8 months by sticking to the walls of a container. In this research, the trend of egg hatching was simulated by using a stage-structured Lefkovitch matrix model. The matrix model consists of a function of egg hatching which associated and depends on rainfall distribution. The purpose of the function is to identify the relationship between egg hatching and rainfall which provide water to egg. Using the same mathematical model, the population of adult Aedes aegypti has also simulated which the population related to egg simulation and rainfall. The graphical results were shown to illustrate the relationship between the rainfall, egg number and adult Aedes aegypti. We found that there was a significant relationship between the rainfall and these two stages of mosquito life cycle which are egg hatching number and adult Aedes aegypti. However, it is recommended to look for more possible factors such as the size of an opening container and humidity which possible to contribute to the development of mosquito to acquire more accurate results.
Contribution/ Originality
The study contributes in the existing literature which stated that both factor rainfall and temperature involved in the development of mosquito life cycle. We found that, the rainfall distribution factor is the most significant to identify the trend of development of mosquitos’ population and meanwhile the factor of temperature influences more on the increase of dengue virus transmission.
