[Ab] Resumo:BACKGROUND: Paleoparasitology reveals the status of parasitic infections in humans and animals in ancient times based on parasitic particles found in biological remains from archaeological excavations. This line of research emerged in Iran in 2013. OBJECTIVE: The identification of parasites from Neolithic times is an attractive subject that shows the oldest origins of parasitic infections in a given geographical region. From an archaeological point of view, this archaeological site is well-known for animal domestication and agriculture in ancient Iran. METHODS: In this study, soil deposited on the surface and in the pores of a dog pelvic bone was carefully collected and rehydrated using trisodium phosphate solution. FINDINGS: The results showed ascarid and taeniid eggs retrieved from the biological remains of a dog excavated at the East Chia Sabz archaeological site, which dates back to the Neolithic period (8100 BC). MAIN CONCLUSION: The current findings clearly illustrate the natural circulation of nematode and cestode parasites among dogs at that time. These ancient helminth eggs can also be used to track the oldest parasitic infections in the Iranian plateau and contribute to the paleoparasitological documentation of the Fertile Crescent.

[Ab] Resumo:Maternally derived antibodies can provide partial protection against certain bacterial and viral infections. We investigated whether chicks descending from nematode-infected hens are more resistant against Ascaridia galli, a prevalent gastrointestinal nematode, than chicks from nematode-free mothers. One-day-old chicks (N=153) from infected (mab+; maternal antibody+) or uninfected control dams (mab-) were experimentally infected with A. galli at two different levels (100 or 1000 eggs/chick). The worm burdens of the chicks were determined at 6 weeks post infection. There was a high correlation (r=0.89) between A. galli-specific antibody concentrations in dam plasma and egg yolk. There was no difference between worm burdens of chicks descending from infected or uninfected dams (P=0.892), indicating no maternally derived protection against A. galli. Chicks receiving the higher infection dose had higher worm burdens (P<0.05). Although there was no difference (P>0.05) between worm counts of female and male chicks infected with 100 eggs, females chicks infected with 100 eggs harboured longer and heavier female worms. We conclude that there is no protective maternal immunity against A. galli infection.

[Ti] Título:Comparison between anthelmintic treatment strategies against Ascaridia galli in commercial laying hens.

[Ab] Resumo:The efficacy of a sustainable deworming strategy based on targeted treatments (TT) against Ascaridia galli was investigated for the first time in laying hen flocks on a Swedish commercial farm. Three experimental protocols with different levels of treatment, e.g. targeted treatment (TT), conventional treatment (CT) and untreated (UT), were tested in randomly allocated flocks of two different bird hybrids. Every second week faecal egg counts (FECs) were determined from pooled faecal materials collected on trays (20×27cm) placed for a maximum of 12h on the litter belts. In the TT, anthelmintic administration (fenbendazole, 1mg/kg body weight for 5days) started at 22 weeks post placement (wpp) and was repeated twice when the pooled FECs surpassed the assigned threshold of 200 egg per gram faeces (EPG). The CT flocks were treated once at 27wpp using the same anthelmintic. Hens in the UT were not dewormed and served as controls. Additionally, FECs on cloacal contents, worm fecundity and worm burdens were determined at 19, 35 and 45wpp. None of the flocks became infected until after 16wpp. The cumulative pooled FECs at the end of the study were significantly (p<0.01) lower in the TT compared to both CT and UT. Although repeated treatment in the TT protocol did not affect the fecundity, a worm density-dependent increase in fecundity was observed. Cloacal FECs and the number of adult A. galli in TT at 35 and 45wpp were significantly lower compared to other flocks. This study provides evidence that the TT strategy is better in terms of lower worm burden and decreased cumulative environmental parasite egg numbers compared to CT strategy. The TT strategy should be considered as an alternative to the CT strategy with regard to A. galli control in commercial laying hens.

[Ab] Resumo:The aim of this study was to investigate whether two highly prevalent helminth infections (Ascaridia galli and Heterakis species) are associated with an increased mortality rate for hens at the peak of lay. An observational event study with 11 farms was conducted between 2012 and 2013, with weekly mortality recordings and grouping of the farms into low-infected with A galli and Heterakis species (0-200 epg of faeces) or high-infected (over 200 epg of faeces). Survival analysis was performed using a discrete time proportional hazards model. The difference between the hazard functions for low-infected farms and high-infected farms in either summer (August to September) or winter (January to March) were analysed. No statistically significant associations were found between the mortality rate in winter and summer in low-infected farms. However, the mortality rate was doubled for hens from high-infected farms observed in the summer season compared with hens from low-infected farms (winter and summer), whereas high-infected farms observed in the winter did not have a significant association between mortality rate and season compared with low-infected farms (summer and winter). The results suggest that the mortality in organic egg production may be reduced by measures to control A galli and Heterakis species infections.

[Ab] Resumo:Infection with the poultry roundworm Ascaridia galli has increased in European countries due to the ban on battery cages. This study was conducted in two commercial laying hen flocks (F1 & F2) on different farms in central Sweden. The aims were to (1) investigate the efficacy of flubendazole (FLBZ, 1.43 mg/kg administered in drinking water for 7 days) against adult and larval stages including histotrophic larvae of A. galli, and (2) determine how long it took before the flocks were reinfected after deworming. Accordingly, 180 randomly selected hens were sacrificed before drug administration (bd), on day 3 and 7 during drug administration (dd), and on a weekly basis for up to five weeks post drug administration (pd). Intestinal contents and cloacal materials of each hen plus pooled faecal samples from manure belts were investigated to assess the worm burden and the parasite egg per gram faeces (epg). Additionally, drinking water, and serum and gastrointestinal digesta content samples obtained from ten treated animals were analyzed by HPLC to measure FLBZ and its reduced (R-FLBZ) and hydrolyzed (H-FLBZ) metabolites. No parasite eggs were observed in cloacal samples on day 21 and 28 pd on F1 and on day 21 pd on F2. The epg in manure decreased by 65% and 88% on day 3 dd and by 99% and 97% on day 35 pd on F1 and F2 respectively. Mean FLBZ concentrations quantified in duodenal contents ranged between 0.50 and 0.79 µg/g. Although, no histotrophic larvae were found dd, they reappeared one week pd (7 ± 7 F1, 0.5 ± 0.5 F2). Adult worms were found in both flocks before drug administration (44 ± 20 F1, 35 ± 25 F2), on day 3 dd (4 ± 3 F1, 2 ± 2 F2), and then not until day 35 (0.2 ± 0.6) on F1 and day 28 (0.4 ± 0.9) pd on F2. Thus, the only period in which no A. galli were found was on day 7 dd. Although FLBZ was highly efficient our results indicate that the birds were reinfected already within one week pd.

[Ab] Resumo:Ascaridia galli is one of the most common nematode affecting chickens. This study characterized A. galli parasites collected from South African village chickens of Limpopo (n=18) and KwaZulu-Natal (n=22) provinces using the 510bp sequences of cytochrome C oxidase subunit 1 gene of the mitochondrial DNA. Fourteen and 12 polymorphic sites were observed for Limpopo and KwaZulu-Natal sequences, respectively. Six haplotypes were observed in total. Haplotype diversity was high and ranged from 0.749 for Limpopo province to 0.758 for KwaZulu-Natal province isolates. There was no genetic differentiation between A. galli from Limpopo and KwaZulu-Natal provinces. The six South African haplotypes were unique compared to those published in the GeneBank sampled from Hy-line chickens raised under organic farming in Denmark. The utility of cytochrome C oxidase subunit 1 gene as a potential genetic marker for studying A. galli in village chicken populations is presented.

[Ab] Resumo:Experimental infection models for Ascaridia galli rely on the use of eggs isolated either directly from worm uteri or from host faeces. We investigated whether A. galli eggs isolated from the two sources differ in their embryonation ability. A. galli eggs originating from 12 worm infrapopulations were isolated both from faeces of the living host (faecal eggs) and directly from worm uteri after host necropsy (uterine eggs). The isolated eggs from each infrapopulation and source were incubated in Petri dishes (n=24) containing a potassium-dichromate (0.1%) medium for 28 days (d) at room temperature. Starting from the day of egg isolation (d0), in ovo larval development was evaluated every second day by examining morphological characteristics of 200 eggs/petri dish. A total of 72,000 eggs were classified into undeveloped, early development, vermiform or fully embryonated stages. Isolation procedures caused similar damage to uterine and faecal eggs (2.2% and 0.5%, respectively; P=0.180). The first sign of in ovo embryonic development in faecal eggs (7%) was observed during the 24-h period when faeces were collected. On d28, a higher percentage of uterine eggs remained undeveloped when compared with faecal eggs (58.6% vs 11.0%; P<0.001). Although a higher (P<0.001) percentage of faecal eggs entered both the early developmental and vermiform stages, which took place primarily within the first two weeks of incubation, there was no time-shift between the development of faecal and uterine eggs. Starting from day 10, higher (P<0.05) percentages of faecal eggs completed embryonation compared with uterine equivalents. Eggs from both sources reached a plateau of embryonation by the end of 2nd week of incubation, with faecal eggs having a greater than two-fold higher embryonation ability. Cumulative mortality was higher in uterine eggs (14.3%) than in faecal eggs (0.2%). We conclude that faecal eggs have a higher embryonation ability than uterine eggs possibly due to maturation differences.

[Ti] Título:Associations between and development of welfare indicators in organic layers.

[Ab] Resumo:The retail market share of organic eggs in Denmark is high, and the consumers expect high animal welfare standards in the organic production. Documentation of animal welfare is important, however, knowledge about the associations between animal-based welfare indicators is limited. The aims of the study were to investigate the associations between selected welfare indicators at two ages (peak and end of lay), and to examine the development with age of the chosen welfare indicators. The chosen welfare indicators were Ascaridia galli (roundworm) infection, Heterakis sp. (caecal worm) infection, keel bone damages, back feathering, body feathering, foot damages, comb colour and wounds on the body. An observational study with 12 organic egg farms was conducted in 2012 and 2013 with a total of 214 hens assessed individually at the peak and the end of lay. Insufficient data were obtained on helminth infection at the peak of lay. At the end of lay, all helminth infected hens were positive for A. galli, and only three of them had in addition a Heterakis sp. infection. Foot damages, pale combs and wounds on the body occurred at frequencies <5% and were therefore, together with the prevalence of Heterakis sp. infection, left out of the analysis of associations. A graphical model was used to analyse the associations between the remaining clinical welfare indicators, A. galli infection, housing systems and age of the hens at end of lay. A. galli infection was only directly associated with back feathering at end of lay (P=0.011) with an increased incidence of A. galli infection in hens with good back feathering. Between the two visits, the prevalence of hens with keel bone damages increased (P<0.001), and the plumage condition deteriorated (P<0.001), whereas the number of hens with plantar abscess (P=0.037) and pale combs (P=0.020) decreased. No significant differences were found for other foot damages or for skin damage. In conclusion, back feathering at end of lay provided information about a possible helminth infection, but this is not a useful indicator in daily on-farm management. In addition, evidence was found that the deterioration of the plumage condition with age was not only due to accumulation of damage over time.

[Ab] Resumo:Ascaridia galli (Schrank, 1788) is a common parasite of various galliform birds worldwide. Although A. galli has been extensively studied by many author, knowledge of the morphology of this species in detail is still insufficient. In the present paper, the detailed morphology of A. galli was further studied using light and scanning electron microscopy, based on specimens collected from the endangered green peafowl Pavo muticus Linnaeus (Galliformes: Phasianidae) in China. The results revealed some erroneous and previously unreported morphological features, including the lips lacking real denticles, the lateral alae beginning at some distance posterior to the base of the ventrolateral lips and the caudal papillae with 4 different morphotypes. The present morphological and morphometric data complement previous descriptions and enable us to recognize this species more precisely.

[Ab] Resumo:This report describes Ascaridia nymphii n. sp., a new species isolated from the alimentary tract of cockatiel Nymphicus hollandicus in Japan. More than 63 nematodes were found in the formalin-fixed small intestine, ventriculus, proventriculus and crop of a 48-day-old young cockatiel that died after exhibiting severe emaciation. No nematode eggs were observed in the faecal examination performed while the cockatiel was alive, but Cryptosporidium oocysts were found. The intestinal mucosa was damaged considerably. Male worms had two alate spicules, well-developed precloacal sucker and a tail with ventrolateral caudal alae and mainly 11 pairs of papillae. Nuclear partial (813 bp) 18S ribosomal RNA gene (18S rDNA) sequences obtained from two female samples were mutually identical. They respectively showed 99.1 and 98.6% identities to those from Ascaridia numidae and Ascaridia galli. Phylogenetic analysis using this locus indicated the present nematode as Ascaridia species. The mitochondrial NADH dehydrogenase subunit 2 gene (nad2) sequences obtained for four samples were mutually identical. They respectively showed 98.7, 85.7 and 82.2% identities with those from Ascaridia columbae, Ascaridia sp. and A. galli. Combining the morphological and sequencing data from two loci, the present nematode was identified as A. nymphii n. sp., which is closely related with A. columbae. This report is the first of a study examining the distribution of Ascaridia species in captive parrots in Japan. This study also identified the trachea and cloaca, like Cryptosporidium baileyi, as the possible location of Cryptosporidium avian genotype V in avian hosts.
