“…Coccidiosis in chickens caused by Eimeria spp. are prevalent worldwide including Bangladesh (Alam et al., 2020; Awais et al., 2012; Franco, 1993; Islam et al., 2020; Jenkins et al., 2017). E. tenella is the most injurious coccidian agent causing haemorrhagic diarrhoea in chickens and significant loss to the global economy.…”

Background Eimeria tenella is the most pathogenic intracellular protozoan parasite of seven Eimeria species causing chicken coccidiosis around the world. This species is particularly responsible for caecal coccidiosis leading to serious morbidity–mortality and financial loss in poultry production. Methods The present study explored the genetic diversity of E. tenella. Litter slurry was collected from 18 broiler farms located in Mymensingh district, Bangladesh. Litter samples were processed for oocyst isolation–identification using parasitological techniques followed by genomic DNA extraction from sporulated oocysts. For molecular analysis, the internal transcribed spacer 1 gene of E. tenella was amplified using species‐specific primers and sequenced. After editing and alignment, 263 bp sequences were used for analysis. Results Genetic analysis showed seven distinct genotypes and detected six single nucleotide polymorphisms among the 18 E. tenella isolates. The nucleotide and genotype diversity were 0.00507 and 0.8235, respectively. A phylogenetic tree was constructed with 66 sequences (seven studied genotypes and 59 reference sequences from GenBank database). The neighbour‐joining tree represented that the studied E. tenella isolates were grouped with reference E. tenella isolates with strong nodal support (100%) and the nucleotide sequences of E. tenella, E. necatrix, E. acervulina, E. brunetti, E. maxima, E. mitis and E. praecox formed separate clusters without any geographical boundaries. Conclusions This is the first study on the genetic analysis of E. tenella from Mymensingh district, Bangladesh. These findings will provide baseline data on the species conformation and genetic variations of E. tenella. Further extensive investigation will be needed to reveal the population genetic structure of this parasite and thus will facilitate the planning of effective control strategies.

“…There is a strong correlation between the occurrence of coccidiosis, relative humidity, temperature, and rainfall. A significant relationship between the season and prevalence of GIT parasites, particularly coccidial infection in rainy season, has been reported in published data of Zimbabwe [ 27 ], Bangladesh [ 28 ], and Andhra Pradesh, India [ 29 ].…”

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.

“…A plethora of reports related to the prevalence of Raillietina in scavenging chickens have been documented worldwide ( Dube et al, 2010 , Hussen et al, 2012 , Mukaratirwa and Hove, 2009 , Mungube et al, 2008 , Paul et al, 2012 , Raote et al, 1991 , Tasawar et al, 1999 ). Along with protozoan diseases, Raillietina is also present in commercial poultry farms and responsible for the economic loss in poultry industry ( Islam et al, 2020 ).…”
