The commonly occurring haemoparasites in pigeons include Plasmodium, Leucocytozoon and Haemoproteus which cause decrease in production and performance of the birds. Due to the dearth of knowledge on prevalence of these parasites in pigeons in Pakistan, current survey-based study was planned to assess the prevalence of above-mentioned parasites in pigeons in selected rural areas of District Faisalabad, Punjab, Pakistan. The morphological identification of parasites was done under microscope by comparing it with standard keys. Out of 384 samples, 56.51% were found positive for haemoparasites. According to town-wise distribution, Jinnah town, Iqbal town, Madina town and Lyallpur town prevalence was 61.24, 48.86, 55.56, and 59.26%, respectively. According to genus-wise distribution, 48.14, 48.21, and 64.92% prevalence of mixed infection, genera Plasmodium/Haemoproteus and Leucocytozoon were observed, respectively. The prevalence was found high in female birds (65.9%) as compared to male birds (51.18%). The prevalence was higher in Cheena (69.02%) and Golden breeds (76.57%) as compared to Sialkoti (32.89%) and Dub wali (37.17%). The prevalence was found higher in squabs (74.15%) as compared to adults (49.6%) and growers (52.56%), in scavengers feeding pattern (77.31%) as compared to feeders (35.78%), and in open coop type (76.68%) as compared to closed coop type (36.12%). The values of Hb, PCV, and RBC's count were lower, while WBC's counts were higher in infected pigeons. The values of uric acid, creatinine, albumin and bilirubin were lower while gamma-glutamyl transferase (GGT), alanine transaminase (ALT), aspartate transaminase (AST) and glucose were higher in infested birds as compared to noninfected birds. The study indicated the impact of haemoparasites on the hematological parameters of the birds and the data generated could help in formulating effective control strategies against haemoparasites particularly Plasmodium, Leucocytozoon and Haemoproteus.

“…of 23 March 2023, 20 haemosporidian lineages (8 Plasmodium, 10 Haemoproteus, and 2 Leucocytozoon) have been registered in wild larids including 3 lineages in wild injured individuals sampled in rescued centers(Bensch et al 2009;Capasso et al 2023;Vanstreels et al 2023). CIAE02 and LARCAC02 are the only Leucocytozoon lineages reported in this family so far.…”

Vector-transmitted haemosporidians are among the most common parasites in birds, but our knowledge of the inter-specific patterns of infection rates and the parasite community composition is far from complete because of the unequal distribution of the screening effort across bird families and genera. To assess infection rates and the diversity of haemosporidians from the genera Plasmodium, Haemoproteus, and Leucocytozoon in marsh terns, which represent poorly explored in this regard genus of the family gulls, terns, and skimmers (Laridae), we screened two species: the Whiskered Tern (Chlidonias hybrida) and the Black Tern (Chlidonias niger). We sampled these long-distance migratory birds on breeding grounds: the Whiskered Tern in south-central Poland and north-central Ukraine, and the Black Tern – in north-central Ukraine. We found that birds from both species were infected only sporadically, with prevalence at the population level not exceeding 3.4%. Only parasites from the genera Plasmodium and Leucocytozoon were detected. There was neither an inter-specific difference nor a difference between populations of the Whiskered Tern in infection rates. In total, we registered three lineages – one Plasmodium and two Leucocytozoon – that were previously recorded in other bird species, and two unidentified Plasmodium infections. One of the lineages (Leucocytozoon LARCAC02) represents a specialist parasite with the host range restricted to larids and geographic range restricted to Poland, and two others (Plasmodium SGS1 and Leucocytozoon CIAE02) represent generalist parasites with very broad host and geographic ranges. This study reinforces the existing evidence that terns host parasites from genera Haemoproteus, Plasmodium, and Leucocytozoon only sporadically.
