Phylogenetic studies on trypanosomatid barcode using V7V8 SSU rRNA and gGAPDH gene sequences have provided support for redefining some species positioning new isolates. The genus Leishmania is a slow evolving monophyletic group including important human pathogens. phylogenetic relationships of this been determined by the natural history its vertebrate hosts, vector specificity, clinical manifestations, geographical distribution molecular approaches different markers. Thus, in an attempt to...
Mycobacterium leprae (M. leprae) is a human pathogen and the causative agent for leprosy, chronic disease characterized by lesions of skin peripheral nerve damage. Zoonotic transmission M. to humans nine-banded armadillos (Dasypus novemcinctus) has been shown occur in southern United States, mainly Texas, Louisiana, Florida. Nine-banded are also common South America, residents living some areas Brazil hunt kill as dietary source protein. This study examines extent infection wild whether...
This study aimed to isolate and genotype T. gondii from Brazilian wildlife. For this purpose, 226 samples were submitted mice bioassay screened by PCR based on 18S rRNA sequences. A total of 15 isolates obtained, including four armadillos (three Dasypus novemcinctus, one Euphractus sexcinctus), three collared anteaters (Tamandua tetradactyla), whited-lipped peccaries (Tayassu pecari), spotted paca (Cuniculus paca), oncilla (Leopardus tigrinus), hoary fox (Pseudalopex vetulus), lineated...
This work aimed to study the possible relationships among magnitude of abomasal worm burden and proliferation globular leucocytes mucosal mast cells in mucosa, white blood cell count. Eighteen Suffolk × Greyface lambs were infected with Haemonchus contortus, 12 kept free nematodes. Blood samples collected on days 0, 30, 57 post-infection (p.i.) for leucogram determination. At day 62, all animals euthanized count total number nematodes recovered abomasum leucocytes. On 57, higher levels...
During 2009-2012, wild animals were sampled in two areas within the Amazon biome of Brazil, states Mato Grosso and Pará. Animal tissues blood molecularly tested for presence Piroplasmida (genera Babesia, Theileria, Cytauxzoon) or Hepatozoon DNA. Overall, 181 comprising 36 different species (2 reptiles, 5 birds, 29 mammals) sampled. The following agents detected: Cytauxzoon felis one ocelot (Leopardus pardalis), Theileria cervi red brocket deer (Mazama americana), spp. three...
We aimed to evaluate the reproductive efficiency of Nelore cows in fixed-time artificial insemination (FTAI) programs with early resynchronization. A total 468 were divided into two experimental groups: R30-conventional resynchronization at 30 days (n = 234); R22-early 22 234). Both groups followed a synchronization protocol using intravaginal progesterone devices combined administration steroids and gonadotropins. The R30 involved after FTAI, while R22 implemented FTAI without prior...
In this study, serum samples of 203 animals from different locations, zoos and breeding facilities the north northeast regions Brazil, were analyzed for presence anti-Toxoplasma gondii antibodies by modified agglutination test (MAT) with a cutoff 1∶25. Of sampled animals, 184 adult mammals both sexes 19 birds. Antibodies found in 61 mammals, no association between sex age T. was observed (P < 0.05). Anti-T. not Toxoplasma detected Brazilian tapir (Tapirus terrestris) first time.
We aimed to evaluate the effects of injectable mineral and vitamin supplementation on weaning calves subjected a low-stress (fence-line) system. Seven-month-old Aberdeen Angus female (n = 40, 152 ± 11 kg body weight) from selenium-deficient area extensive cattle production natural grass were randomly assigned two groups 20 each). One group received subcutaneous with copper, zinc, selenium, manganese vitamins A E (SG), other was given sterile saline solution (CG). The animals supplemented...
Oral diseases are one of the biggest public health problems worldwide, caused by opportunistic pathogens such as Streptococcus mutans and Enterococcus faecalis. Cyperus articulatus (priprioca) is a plant conventionally used in traditional medicine Amazon region. However, little known about possible dentistry-related uses extracts from rhizomes solid waste generated extraction essential oils this vegetable. This study aimed to investigate chemical composition volatile compounds antimicrobial...
In the order Chiroptera, more than 30 trypanosome species belonging to subgenera Herpetosoma, Schizotrypanum, Megatrypanum, and Trypanozoon have been described. The Trypanosoma cruzi, cruzi marinkellei, dionisii are most common in bats belong Schizotrypanum subgenus. Bats from 2 different biomes, Pantanal Amazonia/Cerrado state of Mato Grosso, Brazil, were evaluated according presence parasites by means hemoculture PCR primary samples (blood samples). A total 211 20 caught prevalence,...
Mechanical transmission of the major livestock pathogen Trypanosoma vivax by other biting flies than tsetse allows its spread from Africa to New World. Genetic studies are restricted a small number isolates and based on molecular markers that evolve too slowly resolve relationships between American West African populations and, thus, unable us uncover recent history T. in genetic diversity, population structure source outbreaks was investigated through microsatellite multiloci (7 loci)...
The aim of this study was to evaluate whether zinc (Zn) supplementation protects against hepatic copper (Cu) accumulation in copper-loaded sheep. Forty cross-bred lambs were assigned five experimental groups. These included the control group (C) and four treatment groups that received Cu and/or Zn (dry matter (DM) basis) over 14 weeks, as follows: (450 mg Cu/kg); Zn-35 + 35 Zn/kg); Zn-150 150 Zn-300 300 Zn/kg). Blood, liver, bile samples obtained for mineral determination by inductively...
Acute ruminal lactic acidosis (ARLA) is a major nutritional and metabolic disorder usually characterized by excessive or non-adapted intake of diets rich in nonstructural carbohydrates. Feed additives that regulate the environment have been used to prevent ARLA, such as ionophores and, more recently, yeast culture. Thus, we aimed compare efficacy yeast-based culture (Saccharomyces cerevisiae) with monensin sodium prevention ARLA sheep. Eighteen male, crossbred, rumen-cannulated sheep were...
SUMMARY Trypanosoma ( Megatrypanum ) theileri from cattle and trypanosomes of other artiodactyls form a clade closely related species in analyses using ribosomal sequences. Analysis polymorphic sequences larger number broader geographical origins is required to evaluate the clustering isolates as suggested by previous studies. Here, we determined spliced leader (SL) genes 21 2 water buffalo distant regions Brazil. SL gene repeats revealed that 5S rRNA inserted within intergenic region....
