Objective: This study aimed to evaluate the replacement of degummed soybean oil (DSO) by acid soybean oil (ASO) in diets with or without the inclusion of emulsifier on broiler performance, relative organ weight, lipase activity, intestinal morphometry, and nutrient digestibility. Methods: A total of 704 1-day-old male broiler chicks were allotted to a 2×2 completely randomized factorial design (with or without emulsifier × two lipid sources [ASO and DSO]), with eight replicates and 22 birds each. The metabolizable energy level in diets with emulsifier was reduced by 40 kcal/kg from 1 to 21 d and 50 kcal/kg from 22 to 49 d. Results: Broilers fed diets containing ASO without emulsifier had higher (p = 0.005) weight gain than DSO-fed animals and with the inclusion of emulsifier had worse (p = 0.018) feed conversion ratio (FCR). Birds fed diets with emulsifier worsened FCR regardless of lipid source from 1 to 21 days (p = 0.006) and from 1 to 49 days (p = 0.0002). There was an increase (p = 0.026) in the relative pancreas weight, at 14 days, in birds fed diets containing ASO. Lipase activity and morphometry of the duodenum and jejunum, at 14 and 21 days, were not affected (p>0.05). The dietary inclusion of emulsifier improved the digestible energy (p = 0.053) in the presence of ASO. For the digestibility coefficients (gross energy, crude protein, and mineral matter), no interference was observed (p>0.05). Conclusion: The inclusion of emulsifier to energy-restricted diet with ASO maintained broiler performance in the first week, but worsened FCR in subsequent phases. The ASO can be considered as an alternative lipid source to DSO and does not interfere with the morphophysiological characteristics and performance of broilers. The combination of ASO and emulsifier increased the digestible energy content by 6.2%.

Z-R relationships were developed for the Eastern Coast of Northeastern Brazil (NEB) using rainfall raindrop size distribution (RSD)data collected with a disdrometer RD-69 in the Campus of the Universidade Federal de Alagoas (UFAL: The Federal University of Alagoas) in Maceió in 2001. The RSD was stratified by rainfall rate classes. It is found that the RSD are clearly dependent on the parameters of the analytical distribution functions are, and show a marked monthly variability. The parameters of the frequency distributions are dependent on the rain rate (R). The forms of RSDs are similar to previous studies but the amount of droplets is not in each one very strongly. This may be possible due to the short period of data collection or to the intraseasonal rainfall variability. The general relationship for the Eastern Coast of NEB was found to be Z = 176.5 R1.29, with correlation coefficient equal to 0.83. This equation is in accordance with the ones for stratiform rain reported in the literature. We found that the convective rain observed is produced by convective cells imbedded into stratiform cloud layers. However, when separating stratiform and convective rainfall we found that the linear coefficient of the Z-R relation is significantly smaller for convective rainfall than for stratiform one (65 and 167 respectively), but the exponential coefficient is higher for convective than for stratiform (1.69 and 1.26 respectively).

Osteoma is a benign osteogenic tumor composed of cancellous or compact bone, classified as peripheral, central, or extraskeletal. Peripheral osteomas are uncommon. Excluding the maxillary sinuses, the maxilla is a rare site for osteomas. The purpose of this report was to describe clinicopathological and radiological features of two peripheral osteomas occurring in the jaws, one located in the mandible and another in the edentulous maxillary alveolar ridge. The tumors were asymptomatic and were fully excised without any complications or recurrence. The lesions were submitted to histopathological analysis and diagnosed as peripheral osteoma, compact type.

Autophagic elimination of Trypanosoma cruzi in the presence of metals

Laís Pessanha de Carvalho,Edésio José Tenório de Melo 한국미생물학회 2019 The journal of microbiology Vol.57 No.10

Trypanosoma cruzi is an obligate intracellular parasite transmitted to vertebrate hosts by blood-sucking insects. Molecules present in parasites and mammalian cells allow the recognition and parasite internalization. Metallic ions play an essential role in the establishment and maintenance of hostparasite interaction. However, little is known about how parasites handle with essential and nonessential metal quotas. This study aimed to investigate the influence of metal ions on the biological processes of T. cruzi infected cells. Infected cells were incubated with ZnCl2, CdCl2, and HgCl2 for 12 h and labeled with different specific dyes to investigate the cellular events related to intracellular parasite death and elimination. Infected host cells and parasite’s mitochondria underwent functional and structural disorders, in addition to parasite’s DNA condensation and pH decrease on host cells, which led to parasite death. Further investigations suggested that lysosomes were involved in pH decrease and the double membrane of the endoplasmic reticulum formed vacuoles surrounding damaged parasites, which indicate the occurrence of autophagy for parasite elimination. In conclusion, low concentrations of nonessential and essential metals cause a series of damage to Trypanosoma cruzi organelles, leading to its loss of viability, death, and elimination, with no removal of the host cells.

Ten, Leonid N.,Han, Young Eun,Park, Kyeung Il,Kang, In-Kyu,Han, Jeung-Sul,Jung, Hee-Young MICROBIOLOGICAL SOCIETY OF KOREA 2018 JOURNAL OF MICROBIOLOGY -SEOUL- Vol.56 No.7

A Gram-stain-negative, non-motile, rod-shaped, aerobic bacterial strain, designated <TEX>$1-3-3-8^T$</TEX>, was isolated from soil and characterized taxonomically using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that strain <TEX>$1-3-3-8^T$</TEX> belongs to the family Cytophagaceae of phylum Bacteroidetes and is most closely related to Hymenobacter paludis <TEX>$KBP-30^T$</TEX> (96.8% similarity), Hymenobacter ocellatus <TEX>$Myx2105^T$</TEX> (96.8%), Hymenobacter coalescens <TEX>$WW84^T$</TEX> (95.6%), and Hymenobacter deserti <TEX>$ZLB-3^T$</TEX> (95.4%). The G + C content of the genomic DNA of strain <TEX>$1-3-3-8^T$</TEX> was 63.6 mol%. The isolate contained <TEX>$C_{15:0}$</TEX> iso (28.4%), summed feature 4 (<TEX>$C_{17:1}$</TEX> anteiso B/<TEX>$C_{17:1}$</TEX> iso I; 18.9%), and <TEX>$C_{15:0}$</TEX> anteiso (17.6%) as major fatty acids, MK-7 as the predominant respiratory quinone, and sym-homospermidine as the predominant polyamine. The major polar lipids were phosphatidylethanolamine and an unidentified lipid. The phenotypic and chemotaxonomic data supported the affiliation of strain <TEX>$1-</TEX><TEX>3-3-8^T$</TEX> with the genus Hymenobacter. The DNA-DNA relatedness between strain <TEX>$1-3-3-8^T$</TEX> and H. paludis KCTC <TEX>$32237^T$</TEX> and H. ocellatus DSM <TEX>$11117^T$</TEX> were 24.5 and 27.4% respectively, clearly showing that the isolate is not related to them at the species level. Overall, the novel strain could be differentiated from its phylogenetic neighbors on the basis of several phenotypic, genotypic, and chemotaxonomic features. Therefore, strain <TEX>$1-3-3-8^T$</TEX> represents a novel species of the genus Hymenobacter, for which the name Hymenobacter jeollabukensis sp. nov. has been proposed. The type strain is <TEX>$1-3-3-8^T$</TEX> (<TEX>$=KCTC\;52741^T=JCM\;32192^T$</TEX>).

Ten, Leonid N.,Elderiny, Nabil,Lee, Jae-Jin,Lee, Seung-Yeol,Park, Sangkyu,Lee, Dae Sung,Kim, Myung Kyum,Jung, Hee-Young Springer-Verlag 2018 Current microbiology Vol.75 No.2

<P>A Gram-stain-negative, non-motile, non-spore-forming, rod-shaped, aerobic bacterium, designated 15J8-9(T), was isolated from a sandy beach in Jeju Island, South Korea. The isolate was able to grow between 10 and 30 A degrees C, pH 5-8, and in presence of 0-1% (w/v) NaCl. Based on 16S rRNA gene phylogenetic analysis, the novel strain was closely related to members of the genus Spirosoma (96.1-90.9% similarities) and showed highest sequence similarity to Spirosoma panaciterrae DSM 21099(T) (96.1%). The G + C content of the genomic DNA of strain 15J8-9(T) was 45.1 mol%. The isolate contained menaquinone MK-7 as the predominant respiratory quinone, phosphatidylethanolamine as the major polar lipid, and summed feature 3 (C-16:1 omega 6c/C-16:1 omega 7c; 28.0%), C-16:1 omega 5c (23.4%), iso-C-15:0 (13.5%), and C-16:0 (11.5%) as the major fatty acids that supported the affiliation of strain 15J8-9(T) to the genus Spirosoma. The isolate could be differentiated clearly from recognized Spirosoma species on the basis of several phenotypic, genotypic and chemotaxonomic features. Therefore, strain 15J8-9(T) is considered to represent a novel species of the genus the genus Spirosoma, for which the name Spirosoma harenae sp. nov. is proposed. The type strain is 15J8-9(T) (= KCTC 52030(T) = JCM 31993(T)).</P>

Ten, L. N.,Jung, H.-M.,Im, W.-T.,Oh, H. W.,Yang, D.-C.,Yoo, S.-A.,Lee, S.-T. Microbiology Society 2009 International journal of systematic and evolutiona Vol.59 No.8

<P>A Gram-negative, aerobic, rod-shaped, non-motile, non-spore-forming bacterial strain, designated Gsoil 191T, was isolated from a soil sample from a ginseng field in Pocheon Province, South Korea, and was characterized taxonomically by using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that strain Gsoil 191T belongs to the family Xanthomonadaceae and is related to Dokdonella fugitiva LMG 23001T (97.8% sequence similarity) and Dokdonella koreensis KCTC 12396T (96.9%). The G+C content of the genomic DNA was 68.7 mol%. The major respiratory quinone was Q-8 and the major fatty acids were iso-C17:1omega9c (30.6%), iso-C17:0 (21.6%) and iso-C15:0 (13.0%), supporting the affiliation of strain Gsoil 191T to the genus Dokdonella. DNA-DNA hybridization experiments showed that the DNA-DNA relatedness values between strain Gsoil 191T and its closest phylogenetic neighbours were below 40%. The results of physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain Gsoil 191T from recognized species of the genus Dokdonella. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain Gsoil 191T represents a novel species of the genus Dokdonella, for which the name Dokdonella ginsengisoli sp. nov. is proposed. The type strain is Gsoil 191T (=KCTC 12564T=DSM 17954T=CCUG 52462T).</P>
