The prevalence of gastrointestinal helminth infections and the gross pathological lesions produced by them were studied from February 2012 to January 2013 in the Department of Pharmacology of Bangladesh Agricultural University, Mymensingh. In this study, a total of 320 indigenous chickens aged ranging from 2 to 4 months were examined to identify the different types of gastrointestinal helminth infections in indigenous chickens. During routine examination, six species of helminth parasites were recorded, of which five species of nematodes such as Ascaridia galli, Heterakis gallinarum, Capillaria spp, Acuaria hamulosa and Dispharynx spiralis; and one species was cestode called Raillietina tetragona. The highest prevalence was observed for Ascaridia galli (41.56%) followed in descending order by Raillietina tetragona (19.68%), Heterakis gallinarum (15.62%), Acuaria hamulosa (8.75%), Capillaria spp. (4.68% ) and Disopharinx spiralis (1.56%). The gross pathological lesions were observed in case of Acuaria hamulosa and Heterakis gallinarum infection. In case of Acuaria hamulosa infection keratinization of gizzard mucosa and cross section of adult Acuaria hamulosa were seen along with marked infiltration of neutrophils. The results of this study suggest that both nematodes and cestodes are highly prevalent in indigenous chickens in the studied area.DOI: http://dx.doi.org/10.3329/bjvm.v12i2.21275 Bangl. J. Vet. Med.

The prevalence of gastrointestinal helminth parasites and the gross pathological lesions produced by them in different types of poultry were studied from March 2005 to March 2006, in the Department of Parasitology, Bangladesh Agricultural University, Mymensingh. In this study, 240 viscera of three types of poultry such as broiler, layer and backyard indigenous chickens were collected from local markets of Mymensingh district. During routine examination, total six species of helminth parasites were recorded, of which three species were nematodes such as Ascaridia galli, Heterakis gallinarum and Capillaria annulata; two species were cestodes such as Raillietina tetragona and Amoebotaenia sphenoides and only one species was belonged to trematode such as Catatropis verrucosa. Prevalence of different species of gastrointestinal helminths was highest in backyard poultry (100%) followed by layer (48.75%) and broiler (3.75%) which was statistically significant (p < 0.01). Backyard poultry was significantly (p < 0.05) 168.21 and 4106.67 times more susceptible to helminth infection than layer and broiler respectively. But layer was 24.41 times more susceptible to helminth infection than broiler. In backyard poultry, all six species of helminth parasites were found. A statistically significant (p < 0.05) variation in the prevalence of the recovered parasites from backyard poultry were observed such as the prevalence of R. tetragona (100%) was the highest followed by that of A. galli (87.50%) and H. gallinarum (80%). From the odds ratio of the recovered parasites, it was observed that chance of developing R. tetragona (odds ratio 189.73) in backyard poultry was the highest followed by A. galli (odds ratio 7.51) and H. gallinarum (odds ratio 4.04). In case of layer, only A. galli and R. tetragona were recorded, of which, prevalence of A. galli was the highest (43.75%). In broiler, only A. galli (3.75%) was found. Gross pathological lesions were found only in backyard poultry. Pathological changes were detected in case of A. sphenoides and H. gallinarum infection. In A. sphenoides infection petechial hemorrhages were observed in the mucosa of the duodenum. On the other hand, tiny, white, circumscribed nodules of about 2-3 mm of diameter were found in the caecal mucosa in case of H. gallinarum infection. Results of the present study suggest that the backyard poultry is at the high risk of helminth infection. However, layers are also vulnerable to parasitic infection. So regular deworming is essential both in backyard poultry and layer birds to obtain better production from them.

Gastrointestinal Helminth

The poultry industry is an infant but fast growing sector in Ethiopia. However, it is largely dependent on local chicken managed under backyard production system. The sector is facing different challenges, mainly emanated from prevalence of infectious diseases such as helminth parasite species. Hence, this study came up with an aim to determine the infection rate and identify helminth parasite species in chickens managed under different production systems, in Mekelle, Ethiopia. A cross-sectional study design was employed, from November 2015 to March 2016. Postmortem (N=138) and fecal (N=410) samples of chicken were considered for necropsy and coproscopic examination to see both adult and eggs of helminth parasites, respectively. Similar gastrointestinal helminth parasites infection rate of chicken was obtained from both examination approaches (necropsy, 90.60%; and coproscopy, 90.97%). The study attested high prevalence (87.7%) of mixed infection with helminth parasites of chicken. Heterakis gallinarum (72.5%) and Ascaridia galli (68.8%) were found as the most dominant species (necropsy). During coproscopic examination cestode (89%) infections showed a relatively higher prevalence than nematodes (84.4%), although no difference was observed during that of necropsy examination results. Chickens of local breed from backyard production system had shown more likelihood of getting helminth infection when compared with their corresponding relatives (coproscopy). However, the variation was not statistically significant during that of necropsy finding. Therefore, the higher prevalence of parasitism and mixed infection observed in the study area would warrant for an urgent intervention with regular deworming scheme, and strict attention should be given towards hygienic measures and other health related management activities.

Both helminth infections and contact with allergens result in development of a Th2 type of immune response in the affected individual. In this context, the hygiene hypothesis suggests that reduced prevalence of parasitic infections and successful vaccination strategies are causative for an increase of allergies in industrialized countries. It is therefore of interest to study glycans and their role as immunogenic structures in both parasitic infections and allergies. In the present paper we review information on the different types of glycan structure present in proteins from plant and animal food, insect venom and helminth parasites, and their role as diagnostic markers. In addition, the application of these glycan structures as immunomodulators in novel immunotherapeutic strategies is discussed.

A comparative study was carried out to investigate the gastrointestinal helminth infection in domestic fowls Gallus gallus (30 specimens) and ducks Anas platyrhynchos (30 specimen). A total of 1610 helminth parasites of eight species from three taxonomic classes were recovered and identified from the different parts of alimentary canal. Among the parasitic group the cestodes were turned out to be predominant with a prevalence of 50.93% (820) whereas, the rate was 27.97% (450) and 21.19% (340) in nematodes and trematodes, respectively. The prevalence of parasites species were Ascaridia galli (80%), Echinostoma revolutum (73.33%), Raillientina echinobothrida (53.33%), Echinoparyphium recurvatum (53.33%), Cotugnia digonophora (50%), Amoebotaenia sphenoids (30%), Ascaridia hermaphoridita (43.33%) and Hymenolepis cantania (26.67%). The rate of infestation was higher (90%) in fowls than in ducks (80%) and the intensity of infections was slightly higher in ducks 31.67 (31.48 in domestic fowls). In both domestic fowls and ducks, cestode parasites were most dominant, and prevalence (83.33% and 16.80±4.31) and intensity were lower in fowls than in ducks (76.67% and 17.39 ± 4.2 2). Highest rate of infestation was observed in summer both in fowl (81.82%) and duck (70%) while, winter was associated with peak intensity of parasites in fowl (46.67) and in duck (44.28) observed in summer. The prevalence of parasites was higher in caecum of both domestic fowls and ducks. Bangladesh J. Zool. 49(1): 35-46, 2021

The neutron capture processes in the AlN nanoparticles were investigated by computer modeling. Neutrons absorption were separately investigated for aluminum (Al) and nitrogen (N) atoms in the AlN nanoparticles. The modeling was performed separately for each stable Al and N isotopes, because the effective absorption cross-section of different types of isotopes of Al and N atoms is different. Moreover, effective cross-section spectra of neutron capture for aluminum and nitrogen atoms were comparatively investigated.
