“…Balaenoptera borealis Lesson, 1828 and Balaenoptera physalus L., 1758 (Cetacea: Mysticeti) in addition to Kogia breviceps (Cetacea: Odontoceti) were reported to be parasitized by Pseudoterranova sp. off the Brazilian coast (Santos and Lodi 1998;Pinto et al 2004;Muniz-Pereira et al 2010). A likely explanation for the low prevalence of Pseudoterranova sp.…”

Pseudoterranova larvae parasitizing cutlassfish Trichiurus lepturus and bluefish Pomatomus saltatrix from Southwest Atlantic coast of Brazil were studied in this work by morphological, ultrastructural and molecular approaches. The genetic analysis were performed for the ITS2 intergenic region specific for Pseudoterranova decipiens, the partial 28S (LSU) of ribosomal DNA and the mtDNA cox-1 region. We obtained results for the 28S region and mtDNA cox-1 that was amplified using the polymerase chain reaction and sequenced to evaluate the phylogenetic relationships between sequences of this study and sequences from the GenBank. The morphological profile indicated that all the nine specimens collected from both fish were L3 larvae of Pseudoterranova sp. The genetic profile confirmed the generic level but due to the absence of similar sequences for adult parasites on GenBank for the regions amplifyied, it was not possible to identify them to the species level. The sequences obtained presented 89% of similarity with Pseudoterranova decipiens (28S sequences) and Contracaecum osculatum B (mtDNA cox-1). The low similarity allied to the fact that the amplification with the specific primer for P. decipiens didn't occur, lead us to conclude that our sequences don't belong to P. decipiens complex.

“…Regarding gastrointestinal parasites, trichostrongylid eggs, including Haemonchus spp, Ostertagia spp., and Trichostrongylus spp., showed the highest infection prevalence in the studied marsh deer. In Argentina and Brazil, helminthic diseases are an important cause of morbidity in marsh deer [13][14][15], and H. contortus was found to be one of the most pathogenic agents involved in mortality events [16,17,40]. Ostertagia sp., which was found in this work, was also described in marsh deer in Brazil [14,15,41].…”

“…Tick-borne pathogens have been well documented, with Ehrlichia chaffeensis, Anaplasma phagocytophilum, A. bovis, A. marginale, A. platys, Theileria cervi, Babesia bovis and B. bigemina having been detected and confirmed in marsh deer from Brazil [7][8][9][10], Moreover, the ticks Amblyomma cajennense, A. triste, Dermacentor nitens and Rhipicephalus microplus have been found parasitizing marsh deer in the Brazilian Parana River region [11,12]. Regarding endoparasites, Haemonchus contortus was identified in several South American cervid species [13][14][15], and was recognized as highly pathogenic for marsh deer [16,17].…”

Background: The comprehensive approach to diseases in broad ecological contexts appears as a new challenge for global health and draws on baseline studies to detect changes in the occurrence of pathogens over time. Marsh deer (Blastocerus dichotomus) mortality episodes were described in Argentina and several pathogens associated with environmental and eco-epidemiological factors were indicated as risk factors. To date, the lack of basic health information on these populations has hampered interpretation of findings. This study aimed to provide baseline data on health parameters in marsh deer populations from Argentina. Results: Between May 2014 and December 2016 we determined health parameters in 44 marsh deer with different body condition scores, and studied the pathological lesions in dead animals. Marsh deer with poor body condition had a high burden of the ticks Amblyomma triste and Rhipicephalus microplus. Vector borne agents (VBAs), such as Theileria cervi. Trypanosoma theileri, Trypanosoma evansi, Ehrlichia chaffeensis, Anaplasma platys, Anaplasma odocoilei, Anaplasma marginale, and Candidatus Anaplasma boolense were also found. Haemonchus spp, Ostertagia spp., Trichostrongylus spp. showed the highest infection prevalence. A Multiple Correspondence Analysis suggested a possible association of i) lower body score condition with high tick loads and infection with VBAs and, ii) the impoverished body score with high loads of nemathelminths and well-known harmful gastrointestinal parasites. Conclusions: Our results contribute with knowledge on the life history and health aspects of marsh deer in the study areas. We provide data on the prevalent infectious and parasitic agents in their populations. A range of haematology and serum chemistryvalues, and the occurrence of Fasciola hepatica and Leptospira interrogans serovar pyrogenes were reported for the first time in wild marsh deer from Argentina. The histopathological findings in succumbed animals allowed us to recognize injuries associated or not with their body condition. Our results are the first step in the creation of a baseline on marsh deer health in Argentina. In the future, these data added to new contributions could help improve the interpretation of the findings during mortality events.
