    Hypoderatid mites of the species Hypodectes propus have a complex interaction with their hosts and much remains to be elucidated about these mites. This study was planned based on the observation of small worm-like structures in the subcutaneous adipose tissues of wood pigeons, which were noticed by hunters and caused concern in some state hunting areas in southern Türkiye. In this study, the prevalence of H. propus infestation in wood pigeon populations in Burdur and Antalya provinces of Türkiye was investigated and H. propus deutonymphs were detected in subcutaneous adipose tissues of 72.4% (n: 55) of a total of 76 hunted pigeons. Confirmation that the deutonymphs belonged to H. propus was carried out by microscopy and the combined use of PCR and sequence analysis. Pairwise comparisons of the 18S rRNA gene region revealed that the H. propus isolate identified in the study (PP472912) shared a high nucleotide sequence similarity (99.44%) with a Hypodectes sp. isolate reported from a Great blue heron (Ardea herodias) from the USA (JQ000124). The findings revealed a significant infestation rate, underscoring the burden of ectoparasites on pigeon populations and their implications for avian health. Such infestations can cause stress, reduce reproductive success and increase susceptibility to pathogens, especially in free-ranging pigeons, which may play a role in parasite dynamics within ecosystems. This study is the first report of H. propus infestation with molecular characterization in wood pigeons in Türkiye and it is believed that this study will be useful to scientists and hunters interested in the subject.

    Babesia (B.) ovis is an intra-erythrocytic protozoan parasite that infects small ruminants globally, causing economic losses. This study aimed to investigate the molecular prevalence of B. ovis in 1200 asymptomatic goats of various breeds across four districts in Punjab, Pakistan: Layyah, Lohdran, Dera Ghazi Khan, and Rajanpur. The enrolled goats represented ten breeds, including Daira Din Pannah (n = 890), Pahari goat (n = 68), Nukri (n = 44), Teddy (n = 37), Lail Puri (n = 36), Beetal (n = 36), Dessi (n = 32), Makhi Cheena (n = 27), Muhammad Puri (n = 19) and Fazil Puri (n = 11). The hematological and biochemical profiles of the goats, risk factors associated with the infection, and the phylogenetic relationship of the detected isolates were also evaluated. In total, 105 blood samples (9.6 %) tested positive by PCR. Sanger sequencing of a partial fragment of the 18S rRNA gene confirmed B. ovis. Phylogenetic analysis of the 18S rRNA gene sequences revealed 99-100 % similarity with isolates previously reported from Iran, Iraq, Turkey, and Spain. The infection rate varied across districts, with the highest prevalence observed in goats from Rajanpur (13 %), followed by Dera Ghazi Khan (11 %), Layyah (7 %), and Lohdran (5 %) (P = 0.003). The susceptibility to infection varied among goat breeds, with Lail Puri breed showing the highest susceptibility (P = 0.03). Risk factor analysis revealed that goats under one year of age and those kept on farms where other animals and dogs were also present had higher B. ovis infection rates. Babesia ovis-infected goats showed reductions in white and red blood cells, hemoglobin concentration, and alterations in serum aspartate aminotransferase and creatinine levels. This study provides updated data on the prevalence of B. ovis in local Pakistani goat populations, emphasizing the need for integrated control strategies against this tick-borne pathogen.
