“…Efforts should be intensified to reduce the negative impacts of mycoplasmosis in the poultry industry by adopting biosafety measures and effective vaccinations in the breeder flocks to minimize the vertical transmission of the disease ( El-Naggar et al., 2021 ). It is also supposed to use some safe products such as herbal extracts ( Abou-Kassem et al., 2021a ), essential oil ( Abd El-Hack et al., 2021a ; Alagawany et al., 2021a ; El-Tarabily et al., 2021 ), amino acids ( Abou-Kassem et al., 2021b ; Arif et al., 2021 ), phytogenic products ( Abd El-Hack et al., 2021b , c ; El-Shall et al., 2021 ; Reda et al., 2021 ), enzymes ( Llamas-Moya et al., 2019 ), bioactive peptides ( El-Saadony et al., 2021a , b ), probiotics ( Alagawany et al., 2021b ; El-Saadony et al., 2021c ), plant bioactive compounds ( Abd El-Hack et al., 2021d ; El-Saadony et al., 2021d ), and prebiotics ( Abd El-Hack et al., 2021e ; Yaqoob et al., 2021 ), and biological synthesized nanoparticles ( Abd El-Ghany et al., 2021 ; Abd El-Hack et al., 2021f ) to raise the general health status of birds and improve their resistance to different diseases including mycoplasmosis.…”

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 absence of Meissner's plexuses which sense the lumen environment might be related to smooth muscle hypertrophy ( Pavone et al., 2019 ). Through this study, we recommend paying attention to pigeon breeding and public awareness to reduce the risk of contracting diseases and transmitting these diseases to other avian and animal species as well as humans, through the application of biosecurity & quarantine measures, strengthening the general health of pigeons by using of balanced feed and supplying the bird with safe environmentally friend preparations as herbal extracts ( Abou-Kassem et al., 2021a ; Abd El-Hack et al., 2021a ), essential oils ( Alagawany et al., 2021a ; Dosoky et al., 2021 ; El-Tarabily et al., 2021 ; Mohamed et al., 2021 ), essential amino acids ( Abou-Kassem et al., 2021b ), bioactive peptides ( El-Saadony et al., 2021a , b ), probiotics ( Alagawany et al., 2021b , El-Saadony et al., 2021c ), prebiotics ( Abd El-Hack et al., 2020 , 2021b ; Yaqoob et al., 2021 ), plant-derived natural bioactive compounds ( El-Saadony et al., 2021d ; Raza et al., 2021 ; Seidavi et al., 2021a , b ), biological synthesized nanoparticles ( Abd El‐Hack et al., 2021c , d ; El-Saadony et al., 2021e ), and phytogenic compounds ( Abo Ghanima et al., 2021 , Ashour et al., 2021a ; Abdel-Moneim et al. ; Ashour et al., 2020b , Reda et al., 2021 ).…”

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.

“…The host and microbiome are in a stable relationship where their communication pattern depends on microbial ecology and host immune status ( El-Saadony et al, 2022 ). Microbiota composition can be affected by various dietary factors such as the components of diet, concentrations of nutrients (carbohydrates, fats, proteins, water, minerals, vitamins, and fibers), physical characteristics/structure of feed (grain type and particle size), or supplementation of feed ( Abou-Kassem et al, 2021a ).…”
