| Abstract The first horses were brought to Brazil by the colonizers after 1534. Over the centuries, these animals evolved and adapted to local environmental conditions usually unsuitable for exotic breeds, thereby originating locally adapted Brazilian breeds. The present work represents the first description of maternal genetic diversity in these horse breeds based on D-loop sequences. A D-Loop HSV-I fragment of 252 bp, from 141 horses belonging to ten Brazilian breeds / genetic groups (locally adapted and specialized breeds) were analysed. Thirty-five different haplotypes belonging to 18 haplogroups were identified with 33 polymorphic sites. Haplotype diversity (varying from 0.20 to 0.96) and nucleotide diversity (varying from 0.0039 to 0.0239) was lower... |

| The male of Philometroides acreanensis, parasitic in the anterior intestine external wall of the freshwater catfish Pimelodus blochii, from the Brazilian Amazon, is described for the first time. Additional data on the morphology of females is given. The new morphological data strengthened the validity of the species as well as its first genetic characterization, using three nuclear genetic markers (18S and 28S of the rDNA and ITS1-58S-ITS2), confirmed the high genetic resemblance of male and female specimens. Philometroides acreanensis shows morphological features of the generic diagnosis of Neophilometroides, Alinema, Philometra and Philometroides. Phylogenetic analyses using sequences of the18S rDNA from representatives of Dracunculoidea confirmed the... |

| Biochemical techniques were used to investigate the genetic variability in a Brangus-Ibage population by determining allele frequencies of 18 blood protein systems: Hemogloin beta-Chain (Hb), Albumin (Alb), Amylase (Am), Transferrin (Tf), Carbonic Anhydrase (CA), Ceruloplasmin (Cp), Malic Enzyme (ME), Diaphorase I and II (Dia I and Dia II), Slow Alpha 2 Macroglobulin (Ap), Acid Phosphatase (ACP), Esterase B and D (EstB and EstD), Phosphogluconate Dehydrogenase (PGD), Glucose-6-Phosphate Dehydrogenase (G-6-PD), Glucose-Phosphate-Isomerase (GPI), Superoxide Dismutase (SOD) and Glyoxalase I (GLO). The percentage of polymorphic loci were estimated at 0.27, the mean number of alleles was 1.33 and the mean heterozygosity was 0.07. There was a good agreement... |

| Various genetic markers, including microsatellites, have been used to analyze the genetic polymorphism and heterozygosity in canine breeds. In this work, we used nine microsatellite markers to investigate the genetic variability in Cimarron Uruguayo dogs, the only officially recognized native canine breed in Uruguay. DNA from 30 Cimarron Uruguayo dogs from northeastern and southern Uruguay was analyzed. The allelic frequencies for each micro-satellite, the genetic variability and the consanguinity were calculated, as were the polymorphic information content (PIC) and the probability of exclusion (PE). All of the microsatellites studied were polymorphic. FH 2361, FH 2305 and PEZ 03 were the most informative, with PIC values > 0.7, in agreement with... |

| None of the previous genetic analysis found significant differences within the Mediterranean. However, a more exhaustive analysis is needed inside this sea. In this sense, we have analyzed the mitochondrial control region sequence variability of three Mediterranean locations: Libya (n = 22), Tunisia (n = 23) and Malta (n = 12). Additionally a sample from the Gulf of Cadiz (n = 24) in the East Atlantic Ocean was also included in the study. The AMOVA analysis revealed slightly (Fst = 0.013) but significative genetic differences (P < 0.000) for the Malta location, probably due to its small sample size (n = 12). In the other hand, when this location is removed from the analysis, no differences where found among the three remaining location (Fst = 0,005; P =... |

| Current knowledge of Cryptosporidium species/genotypes in marine fish is limited. Following phylogenetic analysis at the 18S rDNA locus, a recent study identified six new genotypes of Cryptosporidium colonizing edible fish found in European seas. Of these, five grouped in a clade together (#Cryptofish 1–5) and one grouped separately (#Cryptofish 7). In the present study, after phylogenetic analyses of #Cryptofish1, #Cryptofish2, #Cryptofish4, #Cryptofish5 and #Cryptofish7 at the actin locus, the presence of two major clades was confirmed. In addition, when possible, longer 18S amplicons were generated. In conclusion, the small genetic distances between these genotypes designated as a novel marine genotype I (#Cryptofish 1-5) suggest that they may be... |

| Resumo: O grupamento genético ovino pantaneiro tem origem no Pantanal, bioma singular que exerce seleção natural intensa nos animais domésticos naturalizados. Devido às condições ambientais reinantes na planície alagada, os ovinos pantaneiros sul-mato-grossenses desenvolveram características adaptativas e produtivas que justificam a sua conservação. Os estudos até o momento concentraram-se nos aspectos morfométricos, para definição de padrões raciais, e no desempenho produtivo (carne, lã, leite, peles, reprodução e sanidade), que resultaram em bons resultados comparados a raças ovinas exóticas. Os estudos de características genéticas, para orientar os programas de seleção e melhoramento, estão em andamento, com o objetivo de complementar os estudos... |
