Inclusion of microbial fermented soybean meal in broiler feed has induced advantageous outcomes for their performance and gastrointestinal health by exhibiting probiotic effects. In this study, soybean meal (SBM) was subjected to double-stage microbial fermentation utilizing functional metabolites of fungi and bacteria. In the broiler diet, DFSBM replaced SBM at 0%, 25%, 50%, and 100%. DFSBM was reported to have higher protein content and total essential, nonessential, and free amino acids (increased by 3.67%, 12.81%, 10.10%, and 6.53)-fold, respectively, compared to SBM. Notably, phytase activity and lactic acid bacteria increased, while fiber, lipid, and trypsin inhibitor contents decreased by 13.82%, 38.31%, and 73.50%, respectively, in a diet containing 100% DFSBM compared to SBM. Improved growth performance and apparent nutrient digestibility, including phosphorus and calcium, and pancreatic digestive enzyme activities were observed in groups fed higher DFSBM levels. In addition, higher inclusion levels of DFSBM increased blood immune response (IgG, IgM, nitric oxide, and lysozyme levels) and liver antioxidant status. Jejunal amino acids- and peptide-transporter-encoding genes (LAT1, CAT-1, CAT-2, PepT-1, and PepT-2) were upregulated with increasing levels of DFSBM in the ration. Breast muscle crude protein, calcium, and phosphorus retention were increased, especially at higher inclusion levels of DFSBM. Coliform bacteria load was significantly reduced, while lactic acid bacteria count in broiler intestines was increased with higher dietary levels of DFSBM. In conclusion, replacement of SBM with DFSBM positively impacted broiler chicken feed utilization and boosted chickens’ amino acid transportation, in addition to improving the nutritional value of their breast meat.

Neospora caninum (N. caninum) is one of the causative agents that causing cattle abortion, and severe economic losses. Due to the scarcity of data on N. caninum infection in Egyptian cattle, the purpose of this study was to estimate the seroprevalence and determine the risk factors for parasite infection. In four governorates in northern Egypt, 540 blood samples from cattle were taken, and tested using a commercial ELISA kit. The overall seroprevalence of N. caninum in examined cattle was 28.89%. A multivariate logistic regression model determined that age (OR = 2.63, P < 0.001), manual milking (OR = 1.39, P = 0.14), abortion history (OR = 2.78, P < 0.0001), repetition of estrus (OR = 2.31, P < 0.0001), and contact with dogs (OR = 2.57, P < 0.0001) were significant risk factors. The findings proved that N. caninum infection was one of the factors contributing to abortion and financial losses in dairy cattle in Egypt. Therefore, the application of sanitary security and control programs is very important in dairy farms.

Cryptosporidium is one of the causative parasitic agents that causes gastrointestinal diseases in calves. The parasite poses a zoonotic risk to immunocompromised individuals and children. Thus, this study aimed to determine the prevalence of Cryptosporidium infection in calves in three Egyptian governorates situated in Nile Delta and assess the associated risk factors. The Cryptosporidium oocysts were detected in 81 out of 430 calves (18.84%). In addition, the univariant analysis showed that age, feeding source, hygienic status, presence of diarrhea and contact with other animals were significantly (P < 0.05) associated with Cryptosporidium prevalence in calves. Furthermore, the risk factors related with Cryptosporidium prevalence were age (OR 1.96, 95%CI 0.97–3.94), feeding on milk and pasture (OR 2.07, 95%CI 1.15–3.72), poor hygienic condition (OR 2.25, 95%CI 1.28–3.94), presence of diarrhea (OR 2.47, 95%CI 1.23–4.96) and contact with other domestic animals (OR 2.08, 95%CI 1.24–3.50). In addition, the PCR assay targeting 18srRNA showed that the most prevalent species among calves was C. parvum. Although additional researches are required to understand the most effective steps that farmers and veterinary professionals should take to decrease the occurrence of Cryptosporidium infection.

The B3 DNA-binding superfamily is a group of gene families that contain a B3 domain in their proteins. Members of this superfamily are involved in responses to stresses including salt, drought, and cold stress. The B3 DNA-binding superfamily has not been fully studied in Camelina sativa. A total of eighty-seven members of this superfamily were identified in C. sativa. The identified genes were placed into five groups based on a phylogenetic analysis. All the proteins were predicted to be nuclear. The RAV and ARF gene family had the most conserved motifs, with nine out of ten motifs being preserved, while the REM gene family was discovered to have the fewest, with just one conserved motif being present. The RAV and REM gene families showed the least protein–protein interactions. The CsARF5 and CsARF7 genes showed the highest potent interaction score with multiple auxin-responsive proteins. A qPCR analysis was carried out on six genes that showed stress-induced expression changes. CsREM17, CsREM5, and CsRAVL5 were discovered to be considerably increased in response to drought stress, while CsARF10, CsARF4, and CsREM34 were found to be downregulated to a large extent. The B3 DNA-binding superfamily regulates abscisic acid signaling, which in turn influences plant growth and stress resistance.

Background: Toxoplasma gondii is classified as intracellular protozoa and is one of the major zoonotic parasites. Most warm-blooded intermediate hosts, including humans, are commonly infected by this parasite. The epidemiology of T. gondii infection in Egyptian horses is currently poorly understood. Methods: 420 blood samples were randomly collected from horses raised in four governorates in Northern Egypt (110 each from Giza and Kafr El Sheikh, and 100 each from Qalyubia and Gharbia) to investigate the existence of antibodies against T. gondii using a commercial ELISA kit, and to ascertain the risk factors for the infection. Results: the antibodies for T. gondii were found in 16.2% (68/420) of the examined horses, with no significant differences among the four studied governorates. The highest prevalence rate was observed in Giza. The results revealed that sex, breed, age, and contact with domestic ruminants or cats were recognized as potential risk factors. The high prevalence rate was found in mixed breed horses (OR = 2.63, 95% CI: 0.95–7.26), mares (OR = 2.35, 95% CI: 1.31–4.19), and horses aged over 10 years (OR = 2.78, 95% CI: 1.30–3.44). Moreover, the likelihood of seropositivity for T. gondii infection was higher in horses raised in environments with cats (OR = 1.97, 95% CI: 1.13–3.44, p = 0.017) or domestic ruminants (OR = 2.16, 1.21–3.86, p = 0.010). This report confirms that horses in Northern Egypt are exposed to T. gondii and thus raises the possibility that people and other animals could contract the disease. Conclusions: routine examination and management of T. gondii infection in horses in these governorates is advised.
