Abstract
Birds are known to act as the parasite reservoir and can transmit them to other organisms through food chains. This study aims to report the molecular prevalence and phylogenetic evaluation of various blood borne pathogens (Toxoplasma gondii, Isospora spp., Plasmodium spp., Haemoproteus spp., Leucocytozoan spp. and Neospora caninum) in blood samples of common Myna (Acridotheres tristis: N = 80) collected from four region (Jhang, Khanewal, Multan and Muzaffargarh) in Punjab Pakistan. Effect of pathogens on the complete blood count of the host was also determined. Results revealed by 2/80 Myna (2.5 %) amplified ITS-1 gene of Toxoplasma (T.) gondii (confirmed by DNA sequencing) while 2/80 (2.5 %) birds amplified 18S rDNA gene and Isospora spp. Phylogenetic analysis of both pathogens showed that Pakistani isolates were clustered together and were closely related to isolates that were reported from worldwide countries. Risk factor analysis revealed that prevalence of both pathogens was not restricted to a particular sampling site or a particular bird sex (P > 0.05). T. gondii infected birds had elevated red cell distribution width while Isospora sp. infected birds had elevated % monocytes and platelet distribution width while decreased mean cell hemoglobin, mean corpuscular hemoglobin concentration and platelets hematocrit than their respective uninfected birds. In conclusion, we are reporting the presence of T. gondii and Isospora sp. among Pakistani common Myna that had disturbed the complete blood count parameters that may have affected their normal physiology.

Abstract
Biological interactions play an important role in regulating and maintaining natural populations. Like most interactions, parasitism may be influenced by environmental conditions. Therefore, changes caused by human activity may drastically affect the equilibrium of the assemblages of parasitized organisms (hosts). Herein, we described the composition of hemoparasites of anurans from two distinct environments: forest and oil palm plantations. We identified the most frequent groups of blood parasites, and whether infections differ between habitats (forest and plantation) and between microhabitats (arboreal or terrestrial). We collected 128 anurans, of which 46 (36%) were parasitized by hemoparasites. The genus Trypanosoma spp. was found in 30% (n = 37/128) of the infected anurans in both habitats, recorded mostly in terrestrial anurans in oil palm plantations. Apicomplexa hemoprotozoans were also found in 13% (n=17/128) of the anurans, which mainly were terrestrial species collected in oil palm plantations. There was no difference in parasitism between the two assemblies and between the studied microhabitats. This is the first study that has analyzed the ecological relationship between anurans as hosts and their blood parasites, in a region under intense anthropic pressure, in the Brazilian Amazon.

New insights on the diversity of Brazilian anuran blood parasites: With the description of three new species of Hepatozoon (Apicomplexa: Hepatozoidae) from Leptodactylidae anurans. INTERNATIONAL JOURNAL FOR PARASITOLOGY-PARASITES AND WILDLIFE 2021; 14:190-201. [PMID: 33898220 PMCID: PMC8056137 DOI: 10.1016/j.ijppaw.2021.02.009] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/16/2020] [Revised: 02/10/2021] [Accepted: 02/10/2021] [Indexed: 11/24/2022]
Abstract
The Amphibia are considered the most threatened vertebrate class globally, yet in Brazil they are also one of the more diverse and species rich groups. Although, in recent years there has been strong focus on amphibian related research, their parasites have not received the same attention. In Brazil, only a single species of Hepatozoon, namely H. leptodactyli (Lesage, 1908) Pessoa, 1970, has been described from anuran hosts. The present study aimed to describe three new species of Hepatozoon parasitising Leptodactylus labyrinthicus and Leptodactylus latrans from Mato Grosso State, Brazil. From 66 anurans screened for haemogregarines, four belonging to the Leptodactylidae were found positive for species of Hepatozoon. Based on the morphological analysis of peripheral blood gamonts and spleen and liver tissue meronts, three different morphotypes of Hepatozoon spp. were identified. Morphotype 1 (M1) and morphotype 2 (M2) in L. labyrinthicus and morphotype 3 (M3) in L. latrans. Molecular data based on partial 18S rDNA sequences revealed an interspecific divergence, between the species ranging from 0.43% to 1.16%. Phylogenetic analysis recovered isolates from the present study monophyletic with other isolates from Brazilian reptile and anuran hosts, sister to a clade comprising species isolated from African, North American and European reptile and anuran host species. Thus, using morphological and molecular analysis three new species infecting Brazilian Leptodactylidae anurans were identified and described. This study increases the knowledge of Brazilian anurans blood parasites and demonstrates the importance of using integrative approaches for diagnosis of hemoparasites. Diversity and phylogenetic relationship of haemogregarines from Brazilian anurans. Description of a three new species of Hepatozoon from Brazilian anurans. First report of species of Hepatozoon descriptions using both morphological and molecular approaches from Brazilian anurans. Merogonic data of Hepatozoon spp. infection on Brazilian anurans.
