“…The poultry business is one of Egypt's most important agricultural industries, providing a significant portion of the country's animal protein supply (white meats and eggs) ( Salem and Attia, 2021 ). The chicken industry is tied to other industries such as animal feed, medication, and veterinary inputs and provides animal protein for human use.…”

Mycoplasma gallisepticum ( MG ) is a worldwide ruined bacteria affecting different avian species, causing severe economic losses. Consequently, the current research sought to detect the incidence of MG among different commercial broiler, layer chickens and turkey farms, and environmental litter samples in different Egyptian governorates (Damietta, Giza, El-Qalyobia, El-Sharqia, and El-Behera) from January 2019 to December 2020. Four hundred samples (infraorbital sinus aspirates, tracheal swabs, serum from diseased birds, and organ samples; lung tissues, air sacs and tracheal bifurcation from freshly dead birds), and environmental samples (litter) were collected for MG isolation. Samples were subjected to phenotypic and molecular identification. Positive bacteriological samples were subjected for molecular identification using polymerase chain reaction ( PCR ) test to detect MG, then sequencing for PCR amplicon of mgc 2 gene. Out of 332 samples subjected for bacteriological examination, 206 were bacteriologically positive for MG with an incidence of 62%. The highest incidence of MG was detected in turkey farms at a rate of 83%, followed by broiler chicken farms, layer chicken farms and litter samples at a percentage of 70, 40, and 40, respectively. The highest prevalence of MG in chickens and turkey was recorded during the winter and autumn seasons. Molecular identification of MG isolates revealed that 85% of isolates were positive for mgc 2 gene using PCR. The Four sequenced strains in this study are closely related and placed in one group with the vaccine strain 6/85 and ts11 strain.

“…The broiler chicken industry is significant in Egypt, but it is currently facing the challenge of diarrhea infection, a prevalent condition that threatens poultry production. 1 Necrotic enteritis (NE) in chickens is caused by Clostridium perfringens, an anaerobic gram-positive, spore-forming, rod-shaped bacterium. 2,3 C. perfringens is classified into five toxinogenic types (A-E) according to the production of four different major toxins (alpha, beta, epsilon, and iota).…”

Background: Clostridium perfringens-associated necrotic enteritis (NE) is a serious problem affecting broiler production. A major global challenge is to reduce the use of antibiotics in poultry industry due to their negative impacts on public health. One alternative is to use nanoparticles (NPs) to overcome bacterial resistance to antibiotics. Silver nanoparticles (Ag NPs) showed strong antimicrobial activity. Methods: A total of 120 Cobb broiler chicks (1-day old) were obtained for this study and were divided into 4 equal groups at age of 14 days (30 birds each); each group was subdivided into 3 equal replicates (10 birds each). The groups were designated as follows: G1, infected; G2, infected and treated with Ag NPs; G3, treated with Ag NPs; and G4, negative control. Birds were infected with 4×10 8 colony forming unit (CFU)/mL/bird C. perfringens type A for 2 successive days. In the treated groups, Ag NPs (mean diameter 15 nm; total dose 150 µg/bird) were administered via crop gavage. During the observation period (5 weeks), bird performance and immune organ indexes were recorded. Serum samples were collected for immunological evaluation, and tissue samples were collected for histopathology and estimation of Ag NPs residues. Results: Treatment with Ag NPs reduced the colonization of C. perfringens in the intestine and ceca, decreased the severity of clinical signs and reduced mortalities in comparison with infected non-treated group. Ag NPs treatment alleviated pathological lesions in the intestine and liver, but their residues were found in the muscles. Conclusion: Ag NPs have a positive impact on gut health integrity while having no impact on immune organs. Ag NPs have some residues in muscles; therefore, further studies are needed on the concentration and size of Ag NPs, the route of administration, and withdrawal time to ensure the safety of chicken meat for human consumption.

Parasitism is a divesting problem that is frequently overlooked and may result in severe prominent clinical manifestation. This study aimed to investigate the seasonal and sexual prevalence of the gastrointestinal nematode Ascaridia columbae ( A. columbae ) infection among domestic pigeons in Giza governorate, Egypt, during the period from 2020 to 2021. One hundred and sixty suspected pigeons were clinically investigated. Blood & tissue samples were collected from infected birds to estimate serum zinc concentration, malondialdehyde ( MDA ), and nitric oxide levels. As well as tumor necrosis factor-alpha ( TNF-α ), interleukin 1β ( IL1β ) activity, and histopathological examination were estimated; also, worms were collected for morphological identification using electron microscope ( SEM ) and molecularly identified using polymerase chain reaction ( PCR ), further sequenced, and submitted in GenBank with accession number MZ343369. The average ascarid (length × breadth) were 72.4 ± 3.3 µm (70.5 – 79.9 µm) × 39.9 ± 2.5 µm (37.6 – 42.3 µm). The distinguishing morphological characteristics that have been noticed in ascarid worms were creamy white, cylindrical worm with triradiate lips with wide cephalic alae extending on both the lateral sides and filariform esophagus. In males, spicules were almost equal with the presence of precloacal chitinous-rimmed sucker. The prevalence of A. columbae infection was (63.1%) with a higher incidence in females (79.2%) than males (46.1%). The highest seasonal prevalence was observed in winter (92.5%), followed by summer and spring (87.5% and 55%), respectively while, the lowest prevalence was observed in autumn (17.5%). The intensity of worms in the infected intestine varied from 5 to 120 adult worms. The histopathological examination revealed the presence of chronic diffuse moderate catarrhal enteritis with roundworms in the lumen. Infected birds showed a significant increase in nitric oxide and MDA levels while serum zinc levels were lowered in infected pigeons. Infected pigeons revealed a marked increase in IL1-β and TNFα than apparently healthy ones.
