Anaplasmosis, an underestimated tick-borne disease, is a common infection in ruminants including Arabian camels. To our knowledge, few studies have been carried out in Saudi Arabia to identify via molecular methods Anaplasma spp. that infect camels. Therefore, this study was performed to detect and identify Anaplasma spp. in Arabian camels in the Riyadh area of Saudi Arabia. A total of 644 whole blood samples were collected between January 2018 and December 2019. Giemsa-stained, thin blood smears were examined microscopically and then a polymerase chain reaction (PCR) for selected positive samples had been carried out that targeted the specific region of major surface protein 5 (MSP5) of Anaplasma marginale. A total of 273 out of 644 (42.39%) camels were found to be positive by microscopic examination for Anaplasma spp. Amplification of MSP5 gene specific for A. marginale was done. Results of the current study successfully detect A. marginale in camels in Saudi Arabia. To the best of our knowledge, this is the first molecular study that has confirmed the presence of A. marginale in Saudi camels. The MSP5 gene provides a new attractive diagnostic target for detection of A. marginale. Also, the current study highlights the significant levels of camel anaplasmosis in Saudi Arabia.

The study investigates the nonlinear relationship between financial development and economic growth, with a particular focus on the mediating role of FDI in low- and middle-income countries. Using annual panel data covering 81 countries from 1990 to 2019, the study applies a dynamic panel threshold regression model to identify the level of financial development at which its impact on economic growth changes. The analysis incorporates FDI as an additional conditioning variable to examine how its interaction with financial development influences the threshold dynamic. A significant threshold effect: below a certain level of financial development, the impact of FDI on growth is statistically insignificant, while above the threshold, FDI exerts a strong positive influence on economic growth. The findings imply that the growth-enhancing effect of financial development is not automatic and depends on reaching a critical level of financial maturity, as well as an enabling environment that leverages FDI inflows. The study contributes to the literature by offering empirical evidence of a nonlinear, FDI-conditioned finance-growth nexus, and it provides policy guidance for developing economies aiming to optimize the benefits of financial sector reforms.

The relationship between epidemic and society is one of the topics that illustrate the intersection between social and health studies; this research is an interdisciplinary study between health, sociology and media, with the aim of clarifying the mutual effect during COVID-19. The research raises a question about the impact of the official media on social welfare services in the UAE. The importance of the research is due to the continuation of the outbreak of the Corona virus in second wave. The research aims to determine the role of the official media in social welfare during COVID-19. The study used the descriptive method by analysing the content of 95 news items issued by the official news agency in the UAE. The most important findings of the research are that media has a direct impact on social welfare services in all areas of care.
