The present research characterises two extracts based on white grape marc, a winemaking by-product, describing their physicochemical features and antimicrobial capacities. The main components of these extracts are phenolic acids, flavan-3-ols and their gallates and flavonols and their glycosides. As a result of this complex composition, the extracts showed pronounced bioactivities with potential uses in agricultural, pharmaceutical and cosmetic industries. Polyphenol compounds were extracted by using hydro-organic solvent mixtures from the by-product of Albariño white wines (Galicia, NW Spain) production. The in vitro antimicrobial activity of these extracts was evaluated on Gram- positive and Gram-negative bacteria and Apicomplexan and Oomycota parasites. Microbial species investigated are causing agents of several human and animal diseases, such as foodborne illnesses (Bacillus cereus, Escherichia coli, Salmonella enterica,andToxoplasma gondii), skin infections and/or mastitis (Staphylococcus aureus and Streptococcus uberis), malaria (Plasmodium falciparum) and plant infections as “chestnut ink” or “root rot” (Phytophthora cinnamomi). Both extracts showed activity against all the tested species, being nontoxic for the host. So, they could be used for the development of biocides to control a wide range of pathogenic agents and contribute to the enhancement of winemaking industry by-products. Keywords Antibacterial .

Host-parasite interactions between Plasmodium species and New Zealand birds: prevalence, parasite load and pathology A thesis presented in partial fulfilment of the requirements for the degree of Master of Veterinary Science in Wildlife Health At Massey University, Palmerston North New Zealand © Danielle Charlotte Sijbranda 2015 ABSTRACT Avian malaria, caused by Plasmodium spp., is an emerging disease in New Zealand and has been reported as a cause of morbidity and mortality in New Zealand bird populations. This research was initiated after P. (Haemamoeba) relictum lineage GRW4, a suspected highly pathogenic lineage of Plasmodium spp. was detected in a North Island robin of the Waimarino Forest in 2011. Using nested PCR (nPCR), the prevalence of Plasmodium lineages in the Waimarino Forest was evaluated by testing 222 birds of 14 bird species. Plasmodium sp. lineage LINN1, P. (Huffia) elongatum lineage GRW06 and P. (Novyella) sp. lineage SYATO5 were detected; Plasmodium relictum lineage GRW4 was not found. A real- time PCR (qPCR) protocol to quantify the level of parasitaemia of Plasmodium spp. in different bird species was trialled. The qPCR had a sensitivity and specificity of 96.7% and 98% respectively when compared to nPCR, and proved more sensitive in detecting low parasitaemias compared to the nPCR. The mean parasite load was significantly higher in introduced bird species compared to native and endemic species.

Plasmodium (P.) juxtanucleare causes avian malaria in wild and domestic fowl. This study aimed to identify and characterize the Plasmodium species infecting in Thai native fowl. Blood samples were collected for microscopic examination, followed by detection of the Plasmodium cox I gene by using PCR. Five of the 10 sampled fowl had the desired 588 base pair amplicons. Sequence analysis of the five amplicons indicated that the nucleotide and amino acid sequences were homologous to each other and were closely related (100% identity) to a P. juxtanucleare strain isolated in Japan (AB250415). Furthermore, the phylogenetic tree of the cox I gene showed that the P. juxtanucleare in this study were grouped together and clustered with the Japan strain. The presence of P. juxtanucleare described in this study is the first report of P. juxtanucleare in the Thai native fowl of Thailand.

  • Chickens Treated with a Nitric Oxide Inhibitor
    Macchi et al. Veterinary Research 2013, 44:8 http://www.veterinaryresearch.org/content/44/1/8 VETERINARY RESEARCH RESEARCH Open Access Chickens treated with a nitric oxide inhibitor became more resistant to Plasmodium gallinaceum infection due to reduced anemia, thrombocytopenia and inflammation Barbarella Matos de Macchi1,2†, Farlen José Bebber Miranda1†, Fernanda Silva de Souza1, Eulógio Carlos Queiroz de Carvalho3, Antônio Peixoto Albernaz4, José Luiz Martins do Nascimento2† and Renato Augusto DaMatta1*† Abstract Malaria is a serious infectious disease caused by parasites of the Plasmodium genus that affect different vertebrate hosts. Severe malaria leads to host death and involves different pathophysiological phenomena such as anemia, thrombocytopenia and inflammation. Nitric oxide (NO) is an important effector molecule in this disease, but little is known about its role in avian malaria models. Plasmodium gallinaceum- infected chickens were treated with aminoguanidine (AG), an inhibitor of inducible nitric oxide synthase, to observe the role of NO in the pathogenesis of this avian model. AG increased the survival of chickens, but also induced higher parasitemia. Treated chickens demonstrated reduced anemia and thrombocytopenia. Moreover, erythrocytes at different stages of maturation, heterophils, monocytes and thrombocytes were infected by Plasmodium gallinaceum and animals presented a generalized leucopenia. Activated leukocytes and thrombocytes with elongated double nuclei were observed in chickens with higher parasitemia; however,

Since artemisinin was discovered as the active component of A. annua in early 1970s, hundreds of papers have focused on the anti-parasitic effects of artemisinin and its semi-synthetic analogs dihydroartemisinin, artemether, arteether, and artesunate. Artemisinin per se has not been used in mainstream clinical practice due to its poor bioavailability when compared to its analogs. In the past decade, the work with artemisinin-based compounds has expanded to their anti-cancer properties.

  • Evaluation of Hematological Alteration of Vector‐Borne Pathogens in Cats from Bangkok, Thailand Thom Do, Ketsarin Kamyingkird, Wissanuwat Chimnoi and Tawin Inpankaew*
    Do et al. BMC Veterinary Research (2021) 17:28 https://doi.org/10.1186/s12917-020-02737-1 RESEARCH ARTICLE Open Access Evaluation of hematological alteration of vector‐borne pathogens in cats from Bangkok, Thailand Thom Do, Ketsarin Kamyingkird, Wissanuwat Chimnoi and Tawin Inpankaew* Abstract Background: Cats can be carriers of infected arthropods and be infected with several vector-borne pathogens (VBPs) but there is limited knowledge about their pathogenic role in cats. This study aimed to assess the prevalence of some feline vector-borne agents by molecular technique and to characterize the hematological findings associated with these infections in a cat population from Bangkok Thailand. Results: PCR was positive with at least one pathogen in 237 out of 372 subjects (63.7%), with prevalence of 39.5% (147/372) for Babesia spp., 36.9% (137/372) for hemoplasmas and 3.2% (12/372) for Hepatozoon spp. The cats older than 1 year were at significantly greater risk for VBPs infection (P = 0.001; OR = 1.43; 95% CI: 1.12 – 1.81) and hemoplasmas infection (χ2 = 10.8, df = 1; P < 0.0001; OR = 2.45; 95% CI: 1.49 – 4.01). A significant association between hematological findings and hemoplasma infection were identified in the present study. Besides, VBPs infection revealed more frequent in male cats (χ2= 6.38, df = 1, P = 0.01). Macrocytic hypochromic type of anemia was observed in cats infested with blood-sucking arthropods compared to the non-infested cats presented. Conclusions: The current study confirmed that Babesia, Hepatozoon and hemoplasmas had infected semi- domesticated cats in Bangkok, Thailand, with Babesia and hemoplasmas being dominant in prevalence.

  • Recent Advances in the Study of Avian Malaria: an Overview with an Emphasis on the Distribution of Plasmodium Spp in Brazil
    Mem Inst Oswaldo Cruz, Rio de Janeiro, Vol. 106(Suppl. I): 3-11, 2011 3 Recent advances in the study of avian malaria: an overview with an emphasis on the distribution of Plasmodium spp in Brazil Érika Martins Braga1/+, Patricia Silveira1, Nayara Oliveira Belo1, Gediminas Valkiūnas2 1Departamento de Parasitologia, Instituto de Ciências Biológicas, Universidade Federal de Minas Gerais, Av. Antônio Carlos 6627, 31270-901 Belo Horizonte, MG, Brasil 2Nature Research Centre, Akademijos 2, Vilnius 21, LT-08412, Lithuania Avian malaria parasites (Plasmodium) have a worldwide distribution except for Antarctica. They are transmit- ted exclusively by mosquito vectors (Diptera: Culicidae) and are of particular interest to health care research due to their phylogenetic relationship with human plasmodia and their ability to cause avian malaria, which is frequently lethal in non-adapted avian hosts. However, different features of avian Plasmodium spp, including their taxonomy and aspects of their life-history traits, need to be examined in more detail. Over the last 10 years, ecologists, evolu- tionary biologists and wildlife researchers have recognized the importance of studying avian malaria parasites and other related haemosporidians, which are the largest group of the order Haemosporida by number of species. These studies have included understanding the ecological, behavioral and evolutionary aspects that arise in this wildlife host-parasite system. Molecular tools have provided new and exiting opportunities for such research. This review discusses several emerging topics related to the current research of avian Plasmodium spp and some related avian haemosporidians. We also summarize some important discoveries in this field and emphasize the value of using both polymerase chain reaction-based and microscopy-based methods in parallel for wildlife studies.
