Summary: The main objective of this study was to predict the distribution of the bee pest, Megaselia scalaris, in Saudi Arabia using ecological modeling. It was found that the annual mean temperature was the top factor contributing to the distribution of this fly, suggesting its possible occurrence in the northern parts of Saudi Arabia. The study recommends the use of specific bait traps to screen apiaries in the northern areas for the presence of this pest.

Summary: The study investigated the prevalence of Oestrus ovis larvae in sheep and goats' heads from abattoirs in Riyadh, Saudi Arabia. Season had no significant effect on sheep larvae characteristics, except for larval length, while goats had significantly higher L3 instar numbers in summer. Molecular analysis confirmed the presence of O. ovis larvae, closely related to those in GenBank.

Summary: The invasive pest Spodoptera frugiperda was first identified in China in 2019, leading to limited information on its natural enemies. This study reported the presence of parasitic flies Megaselia scalaris infesting S. frugiperda collected from maize fields in four different regions of China. The findings suggest a potential new avenue for integrated pest management strategies in China with the help of indigenous natural enemies.

Summary: Myiasis is a disease caused by dipterous larvae infesting live vertebrates, with cutaneous myiasis being the most common form. It is divided into localized furuncular, migratory, and wound myiasis, with a higher burden in tropical and subtropical countries. We report a case of scalp wound myiasis in a patient with pemphigus vulgaris and raise awareness of potential myiasis caused by Musca domestica in Riyadh, Saudi Arabia.

Summary: This study investigated the development of Megaselia scalaris at different constant temperatures in order to determine its developmental duration, developmental threshold temperature, and thermal summation constant. Three development models were established, and the relationship between body length and total development time was analyzed. The findings of this study provide a foundation for estimating the minimum postmortem interval using M. scalaris.

Summary: The chemical composition of the essential oil obtained from the leaves of Saudi Arabian Capparis cartilaginea Decne. was analyzed, and isopropyl isothiocyanate was identified as a potential chemotaxonomical marker for this plant. The results also indicated that environmental and geographical stressors may influence the essential oil profile of plants within the genus Capparis.

Summary: Malathion, a widely used organophosphorus pesticide, has moderate to high toxicity to nontarget organisms and humans. Its presence in fatal intoxications may affect the growth rate and life cycle of cadaveric entomofauna, leading to potential errors in estimating the minimum postmortem interval (PMImin). Studies show Malathion affects the viability of eggs and pupae, reduces larval growth rate, and prolongs larval stage duration, potentially impacting PMImin estimation in species exposed to tissues containing Malathion.

In the short run, employment reacts to wage growth, but only some sectors respond to output growth. Employment can adjust to equilibrium level in all sectors, but the time horizon for adjustment varies.

Summary: This study investigated the prevalence and characterization of Blastocystis subtypes in Makkah, Saudi Arabia. Results showed that 68.6% of patients were infected with Blastocystis, with ST3 being the most prevalent subtype. All three identified STs resulted in more symptomatic cases than asymptomatic ones. The presence of novel haplotypes in patient stools confirms the genetic diversity of Blastocystis and suggests the need for further molecular epidemiological and genomic studies.

Summary: A cross-sectional study conducted in Egypt found that the seroprevalence of Toxoplasma gondii in dromedary camels was 46.9%. Risk factors for T. gondii infection in camels included locality, sex, age, contact with small ruminants, history of abortion, and number of parities. Evaluating the seroprevalence and related risk factors is crucial for controlling T. gondii infection in camels and preventing transmission to humans.

Summary: This study found that 24% of sheep and 38.28% of goats in three governorates in Egypt were infected with Toxoplasma gondii, and age, sex, contact with cats, and hygienic conditions were identified as risk factors for the infection. The identification of risk variables can help take measures to reduce and prevent T. gondii infection in small ruminant animals and, consequently, human infection.

Summary: This study aimed to determine the prevalence of fascioliasis in sheep slaughtered in Jeddah, Saudi Arabia, and describe the morphological and histopathological changes in the liver. The infection rates of local and imported sheep were 0.67% and 2.12% respectively, with the highest infection rate in the spring season. Grossly, the affected liver showed hepatomegaly, thickened capsule and discoloration with necrosis, fibrosis, dilation of the bile duct, engorgement of the gallbladder, and enlargement of the portal lymph nodes. Microscopic examination revealed fibrotic thickening, calcification and hyperplasia of the bile ducts, as well as massive hemorrhagic foci. Histopathological examinations showed various tissue damage in the infected liver. We concluded that fascioliasis among sheep slaughtered in Jeddah is not uncommon and can lead to significant economic losses for the animals.

Summary: Mycobacterium bovis is a causative agent of bovine tuberculosis and poses a threat to both animal and human health. This study evaluated the effects of BCG vaccine administration in Swiss mice through intranasal and subcutaneous injection. The results showed elevated levels of IgM and IgA in both routes, while subcutaneous injection led to a significant increase in IgG levels. Nebulization of BCG vaccine caused severe pulmonary lesions, while subcutaneous injection had a mild effect on pulmonary tissues and induced extramedullary hematopoiesis in the hepatic tissues. Overall, inadvertent BCG vaccination in Swiss mice resulted in adverse tissue reactions and altered Ig levels, with the severity of tissue lesions corresponding to the injection route.

Summary: Cystic echinococcosis is a serious zoonotic disease that affects both humans and animals, leading to significant economic losses. The study found a prevalence rate of 21.7% of hydatidosis in examined camels. Compared to non-infected camels, those with hydatid cysts showed increased levels of malondialdehyde (MAD) and decreased levels of reduced glutathione (GSH), superoxide dismutase (SOD), and catalase (CAT). Histopathological examination of camel cysts revealed layered membranes surrounded by cellular infiltration and fibrous tissue reaction.
