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

Abstract Currently, descriptive information on the host range and geographic distribution of helminth parasites associated with naturally occurring rodents in South and southern Africa is scant. Therefore, we embarked on a countrywide study to: (1) identify gastrointestinal helminths and their host range, and (2) provide baseline data on the geographic distribution of helminths across the country. Altogether, 55 helminth taxa were recovered from at least 13 rodent species (n = 1030) at 26 localities across South Africa. The helminth taxa represented 25 genera (15 nematodes, nine cestodes and one acanthocephalan). Monoxenous nematodes were the most abundant and prevalent group, while the occurrence of heteroxenous nematodes and cestodes was generally lower. The study recorded several novel helminth–host associations. Single-host-species infections were common, although multiple-host-species infections by helminth species were also recorded. Monoxenous nematodes and some cestodes were recovered countrywide, whereas heteroxenous nematodes were restricted to the eastern regions of South Africa. The study highlights the as yet unexplored diversity of helminth species associated with naturally occurring rodent species and provides initial data on their geographical distribution in South Africa.

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.

Qualitative Estimation

It has been observed that the pH in the different parts of the alimentary canal of Corophium is nearer neutrality; while the medium in the ventral hepatopancreatic caeca is more acidic, being in the neighbourhood of 6.2.Investigations on the qualitative estimation of enzymes indicate that none of the enzymes are secreted by the gut proper. However, the ventral caeca only secrete many of the carbohydrate splitting enzymes; proteases and lipase are also secreted by the caecal cells of CorophiumIt has also been estimated that the optimum pH for the activity of the caecal amylase lies in the neighbourhood of 5.8.

The Mean

Egg production records of White Leghorn pullets hatched a t the Poultry Research Centre, Werribee, Vic., during 1947 to 1950 inclusive have been analysed both on a hen-housed (Production Index) and a survivor basis. Estimates of heritability were obtained by two methods: (1) by the analysis of components of variance between families of full sibs and half-sibs; (2) by estimating the intra-sire regression of the mean performance of offspring on dam's performance. Heritability, in the narrow sense, of Production Index during the pullet year is shown to be 23-30 per cent. with a reasonably low standard error, while heritability of survivors' production is slightly lower but not significantly so. Possible reasons are advanced for the low estimates of heritability of survivors' production.

AbstractChalcides ocellatus, a scincid lizard, sampled during October 1998 to December 1999 from Benina (farmland) and Al-Kueffia (a rocky area) in Benghazi, Libya, was found to harbour three intestinal nematodes, Pharyngodon mamillatus, Thelandros alatus and Parapharyngodon micipsae, and an intestinal cestode, Oochoristica tuberculata. Thelandros alatus, P. micipsae and O. tuberculata were recorded for the first time in C. ocellatus. Parapharyngodon micipsae was detected in C. ocellatus from Benina and O. tuberculata from lizards in Al-Kueffia. The majority (87.6%) of C. ocellatus were infected with helminth parasites and the levels of infection were higher in males than in females but this difference was not significant. Pharyngodon mamillatus recorded the highest number of nematode parasites in C. ocellatus, although there was no relationship between the number of nematode parasites recovered and host density. In lizards infected with the cestode O. tuberculata, males had shorter snout–vent lengths than females. From a total of 153 C. ocellatus, 120 (78.4%) showed single and 14 (9.2%) showed mixed parasitic infections. Mixed infections between different species of nematodes were not observed.

LOC427400 is a novel bird gene located on chromosome Z of the chicken genome. It was deciphered in our previous study by RNA sequencing of different parts of the chicken oviduct. Here we confirmed that LOC427400 expressed significantly high in the magnum comparing with the ovary, isthmus, uterus, liver, jejunum and breast muscle (p Lass Than 0.05) by quantitative real-time PCR in 5 White Leghorn layers at the age of 34 wk. The full length of transcript sequence of LOC427400 was also obtained by 3’ and 5’ RACE. The new transcript was 2831 bp and the corresponding translated protein was 343 aa. The predicted protein show 2 conserved domains, RICIN and OST-beta, which indicated that LOC427400 protein might have functions like carbohydrate-binding and signal transduction. This study illustrated that LOC47400 should be an important candidate gene related with the process of egg albumen formation and albumen biological functions.
