“…Giant cells were also seen in the membrane. Airsacculitis and mycotic granulomatous pneumonia was also reported earlier by Kaboudi et al (2018), where branched septate hyphae, about 10-15 μm in diameter were demonstrated [4] . Our findings are in concordance with the results of Richard et al (1991), Chu et al (2012) and Sultana et al (2014) in commercial turkeys, ducks and chickens, respectively [6,16,18] .…”

“…The disease can occur as an acute form with high mortality and morbidity especially in brooding age called brooder pneumonia [3] , but also has the tendency of chronic form in older birds. The clinical signs observed in these birds were respiratory distress, dyspnoea, gasping and nasal discharge in some birds [4] . The warm, humid environment of the farm sheds, feed stores, floor etc., favor its growth.…”

The present study was carried out to investigate the pathology of Aspergillosis in ducks. A total of 10 cases were recorded during the months of June & July, 2019. The diagnosis was made on the basis of clinical signs, gross & microscopic alterations and isolation of the fungus. The clinical signs observed in the affected ducks include respiratory distress, dyspnoea, gasping and accelerated breathing associated with loss of appetite, stunted growth, lethargy and increased thirst. Grossly, there were presence of whiteyellowish caseous nodules in the lung, airsacs, gizzard, liver, thoracic wall and abdominal serosa. Histopathological examination revealed the presence of focal granulomatous lesions in the lungs characterized by central necrotic area with infiltration of heterophils, macrophages, epithelioid cells and formation of giant cells. Similar type of lesions were also recorded in liver and gizzard. Invasion of fungal hyphae at the peri-bronchiolar and interstitial tissue and haemorrhages were also noticed. On the 5th day post incubation, there were presence of blackish green colonies in the SDA plates.

“…Yeasts and molds are frequently present in food and their development will most often cause various food alterations (changes in texture, color, flavor and appearance). However, some molds, such as Aspergillus flavus and Penicillium viridicatum , are likely to produce mycotoxins, which are dangerous for humans and animals [ 66 , 67 , 68 , 69 ]. The sensitivity to ionizing radiation of yeasts and molds is generally of the same order as that of non-spore-forming bacteria [ 70 ].…”

“…Domijan et al [ 74 ] reported that the cellular toxicity and quantity of aflatoxin B1 and ochratoxin A (in methanol solution) were reduced by 5 to 10 kGy gamma irradiation. Earlier, Kottapalli et al [ 69 ] also reported that the electron beam irradiation of Fusarium infected barley improved the quality of malt by reducing the infection and the deoxynivalenol toxin. Contrarily, sometimes, the sublethal irradiation doses can trigger the growth of some fungi and even the production of mycotoxins [ 75 , 76 ].…”

Ionization radiations are used to ensure food safety and quality. This irradiation process uses ions of beta or gamma rays to inactivate or destroy the food spoilage pests, microorganisms and their toxins without significantly increasing the temperature of the treated product. Meanwhile, various intrinsic and extrinsic factors are involved in determining the efficacy of ionization irradiation against these organisms. Therefore, the dose of radiations is recommended according to the type of irradiation, substrate and microorganisms. However, controversies are surrounding the use of irradiations in the food industry due to a negative perception of irradiations. This manuscript described the use of ionization radiations to control the foodborne biological hazards and increase shelf life. Firstly, the characteristics and mode of action of irradiations were discussed. Secondly, the role of extrinsic and intrinsic factors influencing the radioresistance of biological hazards were elaborated. This literature review also detailed the differential effects of irradiations on different microorganisms and pests having a role in food safety and deterioration. Finally, the regulatory status and the consumer values along with the controversies surrounding the use of ionization irradiations in the food sector were explained.

“…Mallard duck was firstly domesticated in southeast of Asia from 4000 years ago, and was farmed by the Romans in Europe as well to the Malays in Asia [3]. In addition, the ducks were captured in nets in order to breed in captivity by ancient Egypt [4].…”
