Abstract
Birds in a free environment carry huge risk of helminth parasite infections affecting the health of poultry and thereby indirectly leading to great economic loss. The present study aimed to evaluate the prevalence, intensity and species diversity of gastrointestinal helminth parasites (GIH) of country chicken (Gallus gallus domesticus) from local chicken markets of Visakhapatnam district, Andhra Pradesh. A total of 300 gastrointestinal tract (GIT) samples were examined from January to December 2021 and the collected parasites were separated, counted, identified and statistically analysed. The overall prevalence of infection was found to be 87% with an intensity of 139.29. The study showed high prevalence with mixed infections (66%), whereas the prevalence with individual groups i.e. cestodes, nematodes and trematodes was found to be 83.00%, 70.33%, and 0.67% respectively. Altogether 10 parasite species were identified viz. Raillietina echinobothrida being the most dominant with a prevalence of 72.67%, followed by Raillietina tetragona (62.00%), Heterakis gallinarum (59.33%), Ascaridia galli (45.33%), Davainea proglottina (43.00%), Amoebotaenia cuneata (42.67%), Raillietina cesticillus (38.33%), Hymenolepis sp. 1 (36.00%), Cotugnia spp. (29.67%) and the least was Hymenolepis sp. 2 (21.00%). In month-wise data, highest prevalence was recorded in July (100%), and the highest seasonal prevalence was recorded in summer (90%), followed by monsoon (87%) and winter (84%). No major significant difference in prevalence was noted between males (88.51%) and females (85.53%). Hosts with high body temperature and low GIT pH levels showed increased prevalence and parasite intensity.

Abstract
Raillietina spp. (Cestoda: Davaineidae), the most common cestodes in indigenous chickens, cause a substantial production loss in poultry industry in Bangladesh. Here, we estimated the prevalence, confirmed the species and determined the genetic pattern of species of Raillietina using molecular tools. We collected and examined 375 chickens randomly from household of different villages of Mymensingh sadar and Gouripur upazila, Mymensingh district and adult parasites were isolated and identified. Genomic DNA was extracted from collected parasites, amplified ITS-2 and ND-1 genes, sequenced and analyzed. Out of 375 samples, 270 (72.0%) were found positive with Raillietina species and mean worm burden was 10.46 ± 0.56. Microscopically, three species of Raillietina, such as R. cesticillus (37.9%), R. echinobothrida (41.1%) and R. tetragona (52.8%) were detected on the basis of their morphological features. The total length, length and width of scolex, sucker and rostellum were also measured. Among different factors, age, farming nature and flock size of chickens were significantly (p < 0.05) influenced Raillietina infections. For further validation, the sequences of ITS-2 gene generated in this study were matched with reference sequences of R. cesticillus, R. echinobothrida and R. tetragona and found 99.63% - 100% similarity. The phylogenetic analyses of ITS-2 and ND-1 sequences were clustered together with the reference sequences of R. cesticillus, R. echinobothrida and R. tetragona confirming microscopic identification. This is the first confirmation of species of Raillietina along with the prevalence of the species, which will be helpful for the formulation of a control strategy and provide basic information for further molecular study.

Identification of The Main Intestinal Helminths of Local Breed Chickens ( Gallus Gallus Domesticus Linnaeus, 1758) Reared in Traditional Mode in The Oran Region. Helminthologia 2022; 59:170-178. [PMID: 36118364 PMCID: PMC9444204 DOI: 10.2478/helm-2022-0015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2021] [Accepted: 04/20/2022] [Indexed: 11/20/2022] Open
Abstract
In order to gain a better etiological and epidemiological knowledge of the parasitic diseases of local breed chickens reared in extensive (traditional) mode, a study was carried out in the Oran region during the periods from February 2020 to April 2020. Ten chickens were examined by the helminthologic autopsy method to identify parasitic helminths in the digestive tract. Four species of helminths have been identified: two species of nematodes: Ascaridia galli and Heterakis gallinarum and two species of cestodes: Raillietina cesticillus and Raillietina tetragona. Six chickens were carriers of the parasites, for an overall level of infestation of 60 % with an average infestation of 7 parasites per chicken. The rate of parasitism and infestation varied from species to species, Heterakis gallinarum being the most dominant species. The estimate of the infestation rate by each group shows a predominance of nematodes with 62 parasites (88.5 %) compared to cestodes (8 parasites) with a significantly higher difference (P <0.05). The results obtained show that chickens of the local Gallus gallus domesticus breed in the Oran region are heavily infested by parasites including Heterakis gallinarum, the predominant species.

Abstract
Background and Aim Parasitic diseases are an important hurdle to the economy for the developing poultry industry due to their deleterious effects resulting into malnutrition, diminished feed conversion ratio, weight loss, decreased egg production, and mortality in young birds. The aim of this study was to assess the prevalence and associated risk factors of gastrointestinal (GIT) parasites in poultry farms of central plain zone of Punjab. Materials and Methods A total of 490 pooled droppings and 351 intact intestines of poultry from slaughterhouses from seven districts of central plain zone of Punjab state, India, were collected and analyzed from September 2016 to May 2018 by qualitative and quantitative techniques. Results An overall prevalence of GIT parasites was 38.36% with significantly (p<0.01) highest (74.1%) in Ludhiana and lowest (12.0%) in Shri Fatehgarh Sahib. The most predominant (86.2%) infection was coccidia. The birds reared under a deep litter system were having a higher (p<0.01) fecal load of helminthic eggs and coccidian oocysts (54.4%) compared to the cage system (37.5%). Infection rate was apparently more (40%) in broilers than layers (35.7%). Prevalence of GIT parasites was higher (p<0.01) in monsoon season (58.5%) and lower in summer season (24.48%). The broilers in the age group of 0-2 weeks possessed a significant higher (p<0.05) level of GIT parasitic infection (57.5%), while in case of layers, a higher infection rate (46.66%) was observed in birds between 9 and 18 weeks of age as compared in other groups. Higher (p<0.05) infection rate of GIT parasites was seen in crossbred (45.55%) birds as compared to desi birds (20.00%). Conclusion The study showed that coccidiosis was the predominant infection among all GIT parasites based on fecal and intestinal tract content analysis. The risk factors associated with the prevalence of GIT parasitic infections were geographical location, deep litter system, broilers, age, crossbred breeds, and monsoon season.

Abstract
Gastrointestinal helminth parasites are a concern for the poultry industry worldwide as they can affect the health, welfare, and production performance. A systematic review of the prevalence over time in different countries may improve our understanding of gastrointestinal helminthiasis in chickens and subsequently lead to improved poultry health. The aim of this systematic review and meta-analysis was to provide an overview of the published information regarding the epidemiology and the diagnostic approaches of chicken helminth infection. Six databases were searched for studies, and a total of 2,985 articles published between 1942 and 2019 were identified and subsequently screened for eligibility using title or abstract and full text assessment, resulting in 191 publications to be used in the study. Postmortem diagnostics (73.8%) and the flotation technique (28.8%) were commonly used to detect helminth infections with a pooled prevalence of 79.4% ranging from 4 to 100%. More than 30 helminth species in chicken populations were identified including Ascaridia galli (35.9%), Heterakis gallinarum (28.5%), Capillaria spp. (5.90%), and Raillietina spp. (19.0%) being the most prevalent. The reported prevalence of helminth infection decreased over time in developing countries while it increased in the developed world. Chicken kept in backyard and free-range systems had a markedly higher pooled prevalence of helminth infection (82.6 and 84.8%, respectively) than those housed in cage production systems (63.6%). This may indicate the need for more rigorous control and prevention measures in free-range and backyard production systems using regular deworming coupled with access to early and accurate diagnosis allowing for early intervention.

Abstract
Echidnophaga gallinacea is the sticktight flea of chickens. It causes dermatitis and ulcers in the skin and carries some disease-causing agents such as Rickettsia and Bartonella. This study was conducted to detect the infection rate and elucidate the molecular characterization of E. gallinacea in chickens from El-Dabaa City, Matrouh Governorate, Egypt. The fleas were collected from infected chickens and identified morphologically. The internal transcribed spacer-1 (ITS-1) gene PCR method was used for molecular characterization. Based on the morphology, the collected fleas were confirmed as E. gallinacea. The overall infection rate was 5%, with 4.5% in female and 10% in male chickens. ITS-1 PCR revealed a specific band of 488 bp. The ITS-1 gene sequence from Egypt occurred in the same phylogenetic clade as that from Cameroon, with a percentage identity of 98.47%.

Abstract
Parasitic diseases are among the major constraints of poultry production. The common internal parasitic infections occurring in poultry include cestodes and other gastrointestinal helminths. The aim of this study was to characterize Raillietina spp. from the gastrointestinal tract of free-range chickens using 18S rDNA genes. This was achieved through the DNA extraction from tapeworms isolated from the gastrointestinal tract of routine slaughtered free-range chickens using 18S and amplifying the partial 18S rDNA genes using PCR. A total of 34 intestine samples were collected from 9 different areas in Matabeleland region and tapeworms were isolated for microscopic examination and morphological characterization. All 34 chickens examined had tapeworms and morphological characterization confirmed those used in the study as belonging to the Raillietina group. DNA extraction was then successfully carried out for 9 cestode isolates followed by the PCR amplification of the 18S genes. The products were sequenced and 4 of the 9 isolates were positively identified using BLAST as Raillietina tunetensis and the other 5 were only identified as Raillietina spp. These sequences were then aligned with other known sequences of Raillietina isolates from GenBank and a phylogenetic tree was constructed using the neighbor-joining method and distance computed using the maximum composite method. The phylogenetic tree showed that three of the unidentified Raillietina species are in the neighboring position with Raillietina sonini whilst the other two are in the neighboring position with Raillietina tetragona. This is the first record of R. tunetensis in Gallus Gallus domesticus from Zimbabwe. This clustering on the phylogenetic tree however, did not differentiate samples according to geographical location showing that this tool can be used to infer phylogenetic data for speciation.

Abstract
A study was carried out to know the prevalence of gastrointestinal parasites in desi fowl in and nearby villages of Gannavaram, Andhra Pradesh for a period of 1 year. Screening of 492 samples comprising faecal samples and gastrointestinal tracts from freshly slaughtered desi birds at local poultry shops and samples from post mortem examinations at NTR College of Veterinary Science, Gannavaram revealed 63.21 % of gastrointestinal parasites. Faecal samples were examined by floatation technique using salt solution and samples positive for coccidian oocysts were sporulated in 2.5 % potassium dichromate solution for species identification. Adult worms were identified after routine processing and mounting. The species identified includes Davainea proglottina, Raillietina cesticillus and Raillietina echinobothrida in cestodes (32.47 %), Ascaridia galli, Capillaria annulata, Heterakis gallinarum in nematodes (39.87 %), Eimeria tenella, Eimeria acervulina and Eimeria necatrix in Eimeria spp. (39.87 %). Ascaridia galli and R. cesticillus and A. galli and Eimeria spp. were common in mixed infection (12.86 %). Ascaridia galli was the more prevalent species. No trematode parasite was identified during the study period. Significant (p = 0.001) relationship between the seasonality and prevalence of gastrointestinal parasites was observed (χ2 = 17.46, df = 2). Data revealed high prevalence in rainy season (43.41 %) followed by summer (38.91 %) and winter (17.68 %) seasons for all parasites except for A. galli and C. annulata infections which were higher in summer season. Results indicated high prevalence of gastrointestinal parasites in desi fowl in study area emphasizing the need of improved management practices of backyard poultry.

Abstract
During a random survey of parasitisation of poultry birds of Kashmir, conducted for 3 years more than 300 poultry birds were randomly collected from different parts of the Kashmir valley and were examined for the helminth parasites. The most dominant group of parasites which was parasitizing the poultry birds was found to be the Cestode, whose prevalence in the infected birds was 76.9 %. Nematodes were found to be the second dominant group of parasites after cestodes with the prevalence of 70 %. Among the different species of nematodes Heterakis gallinae were found infecting almost all the birds autopsied. The highest intensity of H. gallinae might be because of the fact that it requires cockroaches, beetles and grasshoppers as intermediate hosts in addition of having a direct life cycle. Nematodes which were recovered from the intestine and gizzard of the birds belong to the genera Capillaria, Acuaria, Amidostomum, Streptocara, Heterakis, and Ascaridia.
