Background: Pigeons (Columba livia) have been kept as pet and reared for food in several countries including Iran. Ectoparasites are regarded as the basic causes of retardation in growth, lowered vitality and poor conditions of the birds. Pseudolynchia canariensis a hippoboscidae fly is one of the important ectoparasites of pigeons and is responsible for the transmission of pathogens to birds and humans same as pathogenic protozoan Haemoproteus columbae.
Methods: A herd of domestic pigeons contained 50 pigeons in Shahrekord, southwest Iran was evaluated clinically infested by ectoparasites. Ectoparasites were removed. The samples were collected and then referred to the Laboratory of Parasitology of Shahrekord University, Shahrekord, Iran.
Results: Usin diagnostic key for diptera fly, these flies were find P. canariensis. This is a rare report of infestation of pigeons herd by P. canariensis in Iran. The infestation rate was 40% that rate of infestation in pipers was more than females and in females was more than males.
Conclusion: The rate of infested pipers was more than adults that maybe the less potential of pipers in removing of ectoparasites is reason of this higher rate.

Otobius megnini (spinose ear tick) is a cosmopolitan soft tick that parasitizes domestic and wild mammals, as well as humans. The larval and nymphal stages are common parasites that feed on blood inside the canal ears of hosts, while adults are nonfeeding and live off the host. Different nymphal stages of O.

Schistosomiasis is a tropical infection endemic to developing nations that can result in chronic liver damage, renal failure, infertility, and bladder cancer. Genitourinary localization is marked by dysuria, visible hematuria, and urinary obstruction. We present the case of a 17-year-old male adolescent from a rural area of Central Africa, who arrived in Italy two years prior, exhibiting hematuria and urinary symptoms.

Malaria, transmitted by mosquitoes infected with Plasmodium parasites, remains a significant health issue with global travel increasing the risk of imported malaria. This study investigates imported malaria cases in the Republic of Korea from 2009 to 2018 using data from the Korea National Infectious Disease Surveillance System. During this period, 601 imported cases were reported, with 82.

Protective immunity to malaria depends on acquisition of parasite-specific antibodies, with Plasmodium falciparum erythrocyte membrane protein 1 (PfEMP1) being one of the most important target antigens. The effector functions of PfEMP1-specific IgG include inhibition of infected erythrocyte (IE) sequestration and opsonization of IEs for cell-mediated destruction. IgG glycosylation modulates antibody functionality, with increased affinity to FcγRIIIa for IgG lacking fucose in the Fc region (Fc-afucosylation).

Honeybee colony survival has significantly decreased in many countries over recent decades, which has been associated with multiple factors including pathogens, parasites, resource availability, and environmental stressors, with agricultural intensification playing a key role. This study assessed the effects of Varroa destructor mite infestation, viral prevalence and load, and agrochemical concentrations in the hive matrix on colony strength in two apiaries located in different agricultural contexts (intensive vs traditional) in Northwestern Italy from March to September 2021. The results revealed that colonies in the intensively managed area exhibited lower colony strength and higher mortality rates.
