Composition and structure of the helminth community of Columba livia (Gmelin, 1798) (Aves, Columbidae), in the municipality of Juiz de Fora, Minas Gerais state, Brazil

The objective of the present study was to describe the composition and structure of the helminth community present in domestic pigeons, in the municipality of Juiz de Fora, Minas Gerais, Brazil. The helminthological survey of 35 hosts revealed the presence of two digenetic trematodes, Tanaisia (Paratanaisia) bragai (prevalence 51.42%, mean intensity 288.8 ± 403.86 and mean abundance 148 ± 320.9) and T. inopina (prevalence 2.85% and mean abundance 0.68 ± 4.05); five cestodes, Raillietina allomyodes (prevalence 34.28%, mean intensity 6.66 ± 9.14 and mean abundance 2.28 ± 6.11), Raillietina sp. (prevalence 37.14%, mean intensity 9 ± 10.68 and mean abundance 3.34 ± 7.7), Skrjabinia bonini (prevalence 20%, mean intensity 2.14 ± 1.21 and mean abundance 0.42 ± 1), Skrjabinia sp.( prevalence 5.7%, mean intensity 6 ± 7 and mean abundance 0.34 ± 7) and Fuhrmanneta sp. (prevalence 2.85% and mean abundance 0.028 ± 0.16) and four nematodes, Baruscapillaria obsignata (prevalence 51.42%, mean intensity 29.72 ± 44.2 and mean abundance 15.28 ± 34.7); Ascaridia columbae (prevalence 51.42%, mean intensity 60.55 ± 79.88 and mean abundance 31.14 ± 64.2); Tetrameres fissipina (prevalence 14.28%, mean intensity 346.3 ± 504.4 and mean abundance 49.42 ± 212.1) and Synhimanthus (Dyspharynx) nasuta (prevalence 2.85% and mean abundance 0.028 ± 0.16). Among the examined hosts, 97.2 % were found parasitized by at least one helminth species. In accordance with the prevalence of each species T. bragai, A. columbae and B. obsignata were considered secondary species and T. inopina, T. fissipina, S. nasuta, S. bonini, Skrjabinia sp., R. allomyodes, Raillietina sp. and Fuhrmanneta sp. were considered satellite species. All the species exhibited aggregate distributions, which is the most common distribution pattern in helminth populations.

Ascaridiosis is a very important parasitic disease of birds, it is caused by Ascaridia. This study was conducted to identify the Ascaridia species by microscopic and molecular assay in Baghdad city. One hundred and sixty fecal samples were collected from domestic pigeons during the period from 1/1/ 2019 to 31/3/ 2019. Results showed that the rate of infection for Ascaridia spp. 15.62% by microscopic examination. Significant difference was observed in infection rates between males and females pigeons. Fifty samples randomly selected and subjected to molecular diagnosis of Ascaridia spp.. Molecular examination results, the total infection rate showed 16%(8/50). The eight positive PCR products were sequenced and deposited in Gene bank data base, phylogenic analysis demonstrated that 4 sequences belongs to Ascaridia galli ( MK918635.1, MK918636.1, MK918847.1, MK919081.1), while 2 (MK919199.1, MK919200.1) belong to Ascaridia nymphii and 2 (MK919207.1, MK919264.1) belong to Ascaridia numidae. It is the first study in Iraq to diagnosis of Ascaridia nymphii and Ascaridia numidae in domesticed pigeons by using conventional PCR.

Pigeon haemoproteosis caused by Haemoproteus columbae (Apicomplexa: Haemosporida: Haemoproteidae) is globally prevalent in rock doves (Columba livia), although little is known regarding this disease in pigeons and doves in Indonesia. Blood samples of 35 farmed domestic pigeons (C. livia f. domestica) from four localities in Yogyakarta Special Region, Central Java, Indonesia, were collected from March to June, 2016, subjected to a hemogram, and analyzed for the presence of hemoprotozoan infections. Microscopic examination of blood smears revealed a prevalence of 62.5–100% of H. columbae at the four localities (n = 8–10 for each locality), and geometric means of 3.0–5.6% of erythrocytes were parasitized by young and mature gametocytes, suggesting that all infected pigeons were in the chronic phase of infection with repeated recurrences and/or reinfections. Nucleotide sequencing of mitochondrial cytochrome b gene (cytb) for haemosporidian species demonstrated the distribution of four major cytb lineages of H. columbae (mainly HAECOL1, accompanied by COLIV03, COQUI05, and CXNEA02 according to the MalAvi database). Hemogram analysis, involving the estimation of packed cell volume, erythrocyte counts, mean corpuscular volume, mean corpuscular hemoglobin concentration, and plasma protein and fibrinogen levels of 20 parasitized pigeons and five non-infected pigeons demonstrated significant macrocytic hypochromic anemia with hypoproteinemia and hyperfibrinogenemia in the infected pigeons. This study shows the profound impact of long-lasting subclinical pigeon haemoproteosis caused by H. columbae on the health of farmed domestic pigeons.
