| タイリクモモンガPteromys volansは，フィンランドやエストニア，韓国などでは森林分断化の影響による個体数の減少が危惧されている．北海道の十勝地方においても，過去の森林分断化によって生息地が減少した上に，現在でもさらに生息地の分断化・減少が進行している．本種に対する森林分断化の影響を評価するには，生息確認方法を確立し，生息状況をモニタリングする必要がある．本研究では，糞による簡便かつ効率的な生息確認方法を確立するために，糞が頻繁に発見される場所の特徴や糞の発見効率を検討した．11ヶ所の樹林地（面積0.42–13.69 ha）において，それぞれ10 mの調査ラインをランダムに12本引き，両側4 m（片側2 m）の範囲で糞の有無を確認した．全ての樹林地で本種の糞が発見され，1ヶ所の樹林地あたりの発見糞塊数は平均9.7個，発見ライン数は平均6.2本であった．糞は胸高直径が太い樹木の近くでよく発見され，胸高直径24 cm以上の樹木から20 cm以内の範囲で糞を探すことが効率的であることがわかった．一方で，樹林面積は糞の発見ライン数に影響しなかった．そのため，樹林面積の大きさによって，調査努力量を変える必要はないと考えられた．本調査の結果から，面積に関わらず1ヶ所の樹林地につき5本程度のラインを引いて糞を探すことで，簡便かつ効率的に本種の生息を確認できることがわかった． |

| The efficiency of the Polymerase Chain Reaction (PCR) combined with selective enrichment broth was compared with the standard microbiological techniques for detection of Salmonella Dublin in fecal samples of 10 to 15-days-old Holstein calves, experimentally infected with 10(8) CFU of Salmonella Dublin. Seventy-six fecal samples were analyzed using PCR associated with selenite cystine (SC) and Muller-Kauffmann tetrathionate (TMK) broths and standard microbiological techniques. Regardless of the selective enrichment broth used, the standard microbiological techniques were significantly better than PCR in detection of positive samples of Salmonella Dublin. However, the simultaneous use of both techniques provided detection of a larger number of positive... |

| Three selective enrichment broths - selenite cystine (SC), Muller-Kauffmann tetrathionate (MKT) and Rappaport-Vassiliadis (RV) - were compared, for Salmonella Typhimurium isolation from rectal swabs of a calf experimentally infected. The bacteriological procedure involved pre-enrichment in Hajna-GN broth (only for the samples inoculated in RV broth), selective enrichment (SC, MKT and RV broths), culture in modified brilliant green agar (BGA), presumptive biochemistry tests (using triple-sugar-iron agar and lysine-agar) and slide agglutination test with poli-O and poli-H Salmonella antisera. SC and MKT broths were more efficient in the isolation of Salmonella Typhimurium (12 positive samples), whereas RV broth had a lower efficiency in the microbiological... |

| Swine mycobacteriosis is an important cause of carcass condemnation at abattoirs. One of the best ways to recognize the etiologic agent involved, in live animals, is the fecal isolation, as 94% of the lesions are located in the digestive tract. Therefore, the goal of the present study was to compare the performance of four decontamination methods followed by inoculation in three different culture media, totalizing twelve procedures of mycobacteria search from swine fecal samples experimentally contaminated. The swine feces were artificially contaminated with 0.02 g of Mycobacterium avium, PIG-B strain, and subjected to mycobacteria isolation trial. The protocols used were: 1) modified Petroff or basic method; 2) modified Lowenstein-Jensen or acidic method;... |

| ABSTRACT: The objective of this study was to evaluate endozoochory dispersal, recuperation, and germination of weedy rice (Oryza sativa L.) and barnyardgrass (Echinochloa crus-galli L.) seeds passed through the digestive system of cattle. The experiment was divided into two phases: first, the daily seed recuperation rate was determined after passing through the digestive system of six steers. Each animal was dosed individually with 1000 weedy rice seeds and 13,818 barnyardgrass seeds, and these seeds were subsequently collected from feces. In the second phase, seed germination and emergence rate after passing or not passing through the digestive system of cattle were determined in two types of substrates (fecal plaque and soil) in a 2×2 factorial design.... |

| This study isolated and quantified intestinal bacteria of children with cleft palate before and after palatoplasty. A prospective study was conducted from May 2007 to September 2008 on 18 children with cleft palate, aged one to four years, of both genders, attending a tertiary cleft center in Brazil for palatoplasty, to analyze the effect of surgical palate repair on the concentration of anaerobes Bacteroides sp, Bifidobacterium sp and microaerophiles Lactobacillus sp in feces of infants with cleft palate before and 24 hours after treatment with cefazolin for palatoplasty. There was significant reduction of Lactobacillus sp (p < 0.002), Bacteroides sp (p < 0.001) and Bifidobacterium sp (p = 0.021) after palatoplasty, revealing that surgery and... |

| Abstract The jaguarundi (Puma yagouaroundi) is the second most widespread carnivore of the Americas, and considered a threatened species in Brazil. However, most of its ecology is unknown, and few information is available about species that may act as its predator. In this study we present evidence of the predation of a jaguarundi by puma (Puma concolor) in a protected area (Carlos Botelho State Park) in the state of São Paulo, southeastern Brazil. We collected fecal samples in trails and dirt roads in the study area, and by using hair cuticle imprints and medullar patterns, we identified a puma scat containing hair and claws of a jaguarundi. Pumas usually consume carnivores, but the presence of felids is uncommon, especially in Brazil. This could be... |

| La biodéposition liée à l'exploitation des filières de moules est responsable de l' accumulation de particules fines dans l'environnement marin. Cette biodéposition consiste, à travers la formation de feces et de pseudo feces, en un transfert de particules sestoniques, de la tranche d'eau vers le sédiment. Au cours de ce travail nous avons étudié l'influence des cycles de marée et de l'intensité de celle-ci sur la biodéposition, à travers la mesure de flux verticaux de particules. De même, l'impact de cette biodéposition (aspects qualitatifs et quantitatifs) sur le seston a été abordé. Notre étude montre une variation de l'intensité des flux liée au cycle de marée. Les flux les plus importants sont mesurés lorsque les courants sont les plus intenses,... |

| This study was carried out to investigate the presence of Salmonella sp in flocks of white laying hens. In different farms, the transport boxes of twelve flocks were inspected at arrival for the presence of Salmonella. Four positive (A, B, L and M) and one negative (I) flocks were monitored at each four weeks using bacteriological examination of cecal fresh feces up to 52 weeks. Birds were also evaluated at 52 weeks, when 500 eggs were taken randomly, and at 76 weeks, after forced molt. Salmonella enterica serovar Enteritidis and S. enterica rough strain were isolated from the transport boxes of the four positive flocks (flocks A, B, L and M). Salmonella sp was not isolated from the transport boxes or from the feces after 76 weeks-old in flock I.... |

| Campylobacter was investigated in cecal droppings, feces, and cloacal swabs of 22 flocks of 3 to 5 week-old broilers. Risk factors and the likelihood of the presence of this agent in these flocks were determined. Management practices, such as cleaning and disinfection, feeding, drinkers, and litter treatments, were assessed. Results were evaluated using Odds Ratio (OR) test, and their significance was tested by Fisher's test (p<0.05). A Campylobacter prevalence of 81.8% was found in the broiler flocks (18/22), and within positive flocks, it varied between 85 and 100%. Campylobacter incidence among sample types was homogenous, being 81.8% in cecal droppings, 80.9% in feces, and 80.4% in cloacal swabs (230). Flocks fed by automatic feeding systems... |
