ABSTRACT Background: Domestic pigeons carry pathogens in their droppings, posing a potential public health problem. Methods: The phenotypic and genotypic antimicrobial resistances of Staphylococcus aureus and Enterococcus faecium in the feces of urban pigeons near hospitals with intensive care units were measured. Results: Twenty-nine samples showed Enterococcus growth, whereas one was positive for S. aureus. The S. aureus isolate was sensitive to the antibiotics tested via antibiogram, however resistance genes were identified. E. faecium isolates showed phenotypic resistance to gentamicin, erythromycin, and ciprofloxacin. Conclusions: Antimicrobial profiles harmful to health were demonstrated in bacterial pathogens isolated from the external environment of hospitals.

β-glucans has been reported to be associated with many health-promoting and improvements in animal performance, however, information about their effects on the bacterial community remains unknown. This study aimed to investigate how the addition of β-glucans can affect the fecal bacterial community with possible consequences on animal growth and health. For this, newborn Holstein calves (n = 14) were individually housed in tropical shelters and blocked according to sex, date, and weight at birth and randomly assigned to one of the following treatments: (1) Control: milk replacer (14% solids, 24% CP, 18.5% fat); (2) β-glucans: milk replacer supplemented with β-glucans (2 g/d). All calves were bucket fed 6 L/d of milk replacer and received water and starter concentrate ad libitum starting on d 2. To evaluate the bacteriome, fecal samples were collected at weeks 1, 2, 4, and 8. The bacterial community was assessed through sequencing of the V3-V4 region of the 16S rRNA gene on the Illumina MiSeq platform and analyzed using the DADA2 pipeline. No differences for Shannon and Chao1 indexes were observed for treatments, but both indexes increased with age (P < 0.001). There were dissimilarities in the structure of the bacterial community during the pre-weaning period ( P = 0.01). In a deeper taxonomic level, Collinsella (Actinobacteriota), Prevotella (Bacteroidota), and Lactobacillus (Firmicutes) were the most abundant genera (9.84, 9.54, and 8.82% of the sequences, respectively). β-glucans promoted a higher abundance of Alloprevotella and Holdemanella , which may indicate a beneficial effect of supplementation on dairy calves. The bacterial community was highly correlated with the fecal score at weeks 1 and 2 and with starter concentrate intake at week 8. In conclusion, algae β-glucan supplementation could be beneficial to fecal bacteriome and consequently to the health and performance of dairy calves.

Caracterización limnológica y fauna de peces de la laguna La Helvecia (Córdoba, Argentina)

DOAJ (DOAJ: Directory of Open Access Journals) (2014)

Miguel Mancini Fernanda Biolé Víctor Salinas Gerardo Morra Guillermo Prieto

La Helvecia shallow lake (33°25’16’’S, 62°53’26’’W, 90 ha) is one of the few permanent aquatic environments that still exist in the “Banados del Saladillo” (Cordoba, Argentina). During November 2011, a study of fish and limnological characterization was performed. Different active and passive gears were used and water quality variables were measured. Average values pH, oxygen concentration, temperature and water transparency (Secchi disk) were 8.63, 9.05 mg/L, 23.8 °C and 39 cm respectively. The shallow lake was classified as “turbid” type. The water was hypohaline (4.74 g/L), sulfated sodium chlorinated and very hard (298 ppm CaCO3). The macrozooplankton abundance was 240,850 org/m3. A total of nine species of fish, belonging to five orders and seven families were captured. Odontesthes bonariensis was the most abundant species (78.6%), while Cyprinus carpio was the species with most biomass (41.4%). Zooplankton (Cladocera and Copepdoda) was the main food of O. bonariensis. The principal finding was the presence of Parapimelodus valenciennis. The gradual and permanent changes that have occurred in the landscape of the region, with higher intensities of land use, may have been the main causes of the transformation of La Helvecia lake from clear to turbid, which favored the recreational fishery.

A Transcriptomic Approach to Ribbon Worm Systematics (Nemertea): Resolving the Pilidiophora Problem

Molecular Biology and Evolution (2014)

Sónia C. S. Andrade Horácio Montenegro Malin Strand Megan L. Schwartz Hiroshi Kajihara

Resolving the deep relationships of ancient animal lineages has proven difficult using standard Sanger-sequencing approaches with a handful of markers. We thus reassess the relatively well-studied phylogeny of the phylum Nemertea (ribbon worms)—for which the targeted gene approaches had resolved many clades but had left key phylogenetic gaps—by using a phylogenomic approach using Illumina-based de novo assembled transcriptomes and automatic orthology prediction methods. The analysis of a concatenated data set of 2,779 genes (411,138 amino acids) with about 78% gene occupancy and a reduced version with 95% gene occupancy, under evolutionary models accounting or not for site-specific amino acid replacement patterns results in a well-supported phylogeny that recovers all major accepted nemertean clades with the monophyly of Heteronemertea, Hoplonemertea, Monostilifera, being well supported. Significantly, all the ambiguous patterns inferred from Sanger-based approaches were resolved, namely the monophyly of Palaeonemertea and Pilidiophora. By testing for possible conflict in the analyzed supermatrix, we observed that concatenation was the best solution, and the results of the analyses should settle prior debates on nemertean phylogeny. The study highlights the importance, feasibility, and completeness of Illumina-based phylogenomic data matrices.

"Sex-ratio" citoplasmatico em Drosophila melanogaster

Horácio Montenegro

Elementos geneticos egoistas sao particulas herdaveis de etiologia e mecanismos de acao variados, mas com a caracteritica em comum de modificar a segregacao mendeliana dos alelos em favor proprio, aumentando a propria frequencia. Elementos citoplasmaticos egoistas sao um caso especial de elementos geneticos egoistas, como sao herdados apenas pelo citoplasma materno, eles sofrem selecao para causar desvios na proporcao sexual, em favor de um excesso de femeas. A proporcao sexual nas progenies de organismos que se reproduzem sexualmente e, em geral, 1.___.__)LVKHU________SURS{V_D_SULPHLUD_H[SOLFDoao baseada em selecao natural para esta proporcao. O principio de Fisher prediz que o sexo mais raro tem maior valor adaptativo, pois sua contribuicao media por individuo e maior. Assim, a selecao favorecera alelos que aumentem a frequencia do sexo raro nas progenies. Quando a proporcao chegar a 1.___.__individuos dos dois sexos terao o mesmo valor adaptativo. Parasitas reprodutivos, endosimbiontes herdados maternalmete, representam a maior parte dos elementos citoplasmaticos egoistas, e uma das causas mais comuns de desvios a proporcao de 1.___.__ Agentes androcidas, endossimbiontes que matam os embrioes machos, sao um destes parasitas reprodutivos. Como consequencia, a proporcao sexual da prole das femeas infectadas afasta-se de 1.___.__apresentando excesso ou totalidade de femeas. Agentes androcidas foram encontrados em mais de 40 especies de 6 ordens de insetos. Varions taxons de bacterias ja foram associados com o fenotipo, e a filogenia dos parasitas e hospedeiros nao e congruente, indicando transmissao horizontal frequente. Neste trabalho, estudamos o agente androcida de Drosophila melanogaster, descrito recentemente. Sistematica molecular mostrou que trata-se de uma bacteria do generoSpiroplasma, muito proxima ao agente androcida encontrado em D. nebulosa. As sequencias comparadas (3000 pares de base, representando sequencias parciais de 3 genes) sao identicas, portanto, as duas bacterias tem um ancestral comum muito recente. De fato, possivelmente as duas especies de Drosophila so entraram em contato ha 4 ou 5 seculos, com a expansao mundial de D. melanogaster, e a transmissao do Spiroplasma de D. nebulosa para D. melanogaster deve ter ocorrido depois disso. Em uma coleta em Recife, foi encontrado que 2,3% das femeas estavam infectadas com Spiroplasma; outro parasita reprodutivo, a bacteria Wolbachia (que causa incompatibilidade citoplasmatica) infectava 96% das femeas. Alem disso, as duas bacterias co-infectavam os mesmos individuos, uma observacao ate agora incomum para parasitas reprodutivos com fenotipos diferentes. Como parasitas reprodutivos tem transmissao exclusivamente materna, seu valor adaptativo e altamente correlacionado com o das femeas hospedeiras. Desta forma, espera-se que parasitas reprodutivos nao tenham efeitos deleterios no valor adaptativo das femeas hospedeiras, ou ate que sejam beneficos. Por outro lado, a eficiencia de transmissao ou a intensidade do fenotipo de manipulacao reprodutiva podem estar positivamente correlacionados com a densidade de bacterias no hospedeiro, de forma que parasitas mais eficientes causem efeitos deleterios no valor adaptativo da femea. Para verificar se existem efeitos de Spiroplasma e Wolbachia no valor adaptativo de femeas, medimos a viabilidade larval e a fecundidade de femeas adultas, comparando com a de femeas nao-infectadas. Nenhuma das duas caracteristicas parece ser afetada por Spiroplasma ou Wolbachia, nem por infeccao com as duas bacterias simultaneamente. Finalmente, foi verificado que temperaturas baixas (em torno de 16,5°C) interrompem a transmissao do agente androcida para a progenie das moscas infectadas Abstract
