A Heavy Infection Macro-cysts of &lt;i&gt;Sarcocystis&lt;/i&gt; Spp. Case in a Najdi Sheep at Buraidah Slaughter House, Qassim, Saudi Arabia

The present study aims to investigate the distribution and diversity of dipterous flies in Tayma (Saudi Arabia) during the spring of 2018. A total of 12 dipterous species were collected from three different sites located in Tayma (Tabuk, Saudi Arabia) located in the Northern part of Saudi Arabia. The taxa of flies were dominated by Musca domestica and Musca sorbens. No significant difference were observed between the total number of flies collected using different traps (t-test, P>0.05) and among the studied sites (ANOVA, P>0.05). The highest number of flies was recorded from Site 3 (a cattle farm). However, lower number of flies was reported from the dates palm farms. In conlusion, the species Musca domestica were found to be the most abundant species in all locations with remarkable high abundance in animal facilities (slaughter house and animal farm). The pheromone traps were found to be the most effective trap catching high number of individuls and high number of fly species.

Cellular Components

Crystalline intracellular inclusions are rarely seen in mammalian tissues and are often difficult to positively identify. Lymph node and liver tissue samples were obtained from two cows which had been rejected at the slaughter house due to the abnormal appearance of these organs in the animals. The samples were fixed in formaldehyde and some of the fixed material was embedded in paraffin. Examination of the paraffin sections with polarized light microscopy revealed the presence of numerous crystals in both hepatic and lymph tissue sections. Tissue sections were then deparaffinized in xylene, mounted, carbon coated, and examined in a Phillips 505T SEM equipped with a Tracor Northern X-ray Energy Dispersive Spectroscopy (EDS) system. Crystals were obscured by cellular components and membranes so that EDS spectra were only obtainable from whole cells. Tissue samples which had been fixed but not paraffin-embedded were dehydrated, embedded in Spurrs plastic, and sectioned.
