The Phenotypic characteristics of three genotypes of native chicken comprising of Non-descript Desi (ND), Hilly (H) and Naked Neck (NN) were studied. A total of 180 individual chickens (Male: ND= 20; H= 20 and NN=20; Female: ND= 40, H=40 and NN = 40) were characterized under intensive management system for qualitative and quantitative traits. The results indicated that the predominant plumage color of three types of native chickens was black brownish (33.33%) followed by white with black tips (28.33 %) and red brownish (18.33%). Values indicate that 35% of native chickens had whitish shank color followed by yellowish 31.68%; black 11.66 % and others 21.67 %. All hens of ND, H and NN laid light brown (62.42%) to cream or off white (30.28%) colored eggs. Variations were also found on quantitative traits such as shank length, body weight and reproductive traits on intensive management system. number of eggs/ hen from starting to ten months of laying were 108, 104 and 112, respectively in ND, H and NN genotypes. Three native chicken genotypes showed distinct physical variations for both qualitative and quantitative traits under intensive management system.

Abstract A study was conducted to characterize four phenotypes (black, white with black tips, light brown and dark brown) of naked neck chickens [n=320; 80(40♂, 40♀)] for qualitative and quantitative traits at 20 weeks of age. Qualitative phenotypic characterization was based on head appearance, comb type, wattle size, plumage pattern, shank color, spurs prevalence and number of toes. Quantitative phenotypic characterization was based on neck length, keel length, shank length, drum stick length, body length, wing span and circumference. Males and females of all phenotype had plain head and single comb. Plain feather pattern was predominantly most frequent on breast, wing bow, wing bar, wing bay, saddle and tail followed by stippled, penciled and laced. Males had most frequent yellow shanks followed by grey, off-white and green. White black, light and dark brown phenotypes expressed maximum yellow shank coloration whereas grey shanks were most frequent in black birds. Morpho-metric measurements were significantly higher in males than females. Light and dark brown phenotypes had higher values of quantitative traits than those of black and white black. All males and females of naked neck phenotypes possessed four toes, normal spurs and tuft feathers on the ventral portion of the neck above crop. The phenotypic variation observed in indigenous naked neck chickens could provide valuable basic information to develop effective utilization and conservation programs.

This work was carried out on the phenotypic characteristics of the Kababich sheep exploited in the peri-urban zone of N'Djamena (Chad). This phenotypic characterization of Kababich sheep should be continued on local breeds for genetic improvement and objective optimization of productivity. The objective of this study is the characterization of phenotypically Kababich sheep exploited in the peri-urban area of ​​N'Djamena-Chad. It was conducted in 39 farms and involved 1035 sheep aged less than one year old. Phenotypic traits were measured according to the guideline defined by FAO. A total of 12 variables were measured including five qualitative and seven quantitative. The results obtained show a positively significant correlation (p> 0.001) between the age of the sheep estimated by the breeder and the dentition (0.83). The ears are drooping and measure 17.90 ± 2.77 cm. The color of the brown dress (fawn) and the smooth and short coat are dominant. The females are matte and the rams of brown dress have horns in the forms of the vestiges. The Kababich is large with a height at the withers of 81.50 ± 9.40 cm, a rump height of 83.24 ± 9.42 cm and a chest circumference of 88.29 ± 9.22 cm. The body is 72.82 ± 9.63 cm long, has a basin width of 19.89 ± 2.53 cm and a chest depth of 40.68 ± 5.16 cm. These measurements show that Kababich is a meat breed by excellence. In addition, the sexual dimorphism very accentuated in this race orients towards a valorization of the young males in the fattening workshops.

Morpho-agronomic characters consist of two types of qualitative and quantitative characters. Qualitative characters were discontinuous and score data form, while the quantitative are continuous and measurable. Kinship analysis is important for breeders to know the genetic distance between genotypes. Allegedly there are differences in the genetic kinship analysis between based on data from qualitative to quantitative character. The aim of this study was to compare the results of the analysis of kinship based on quantitative and qualitative data on phenotypic characterization of local rice. A total of 43 local rice from West Java was used on phenotypic characterization activities. The research was done at Sukamandi experiment station of ICRR (Indonesian Rice Research Institute) on 2014. Qualitative characters were observed as many as 24 characters, and quantitative as many as 23 characters. Analysis of data was by using Minitab version 14. The results indicate that kinship analysis results using data from qualitative, quantitative or a combination of both was not significantly different at the component level analysis of the number of clusters and similarity but there were real differences in the level of genetic distance. Dendogram based on qualitative characters was different than based on quantitative character. Analysis of kinship between genotype recommended using a data combination of qualitative and quantitative character that the genetic distance between genotype information more accurately

The genetic architecture of 10 rural poultry populations in two distant tribal districts of Mayurbhanj and Kalahandi of Odisha state in India were studied for 15 quantitative and 11 qualitative characteristics through a field survey. Analysis of dispersion was conducted to test the simultaneous significance of mean differences in above characteristics and was found to be highly significant (p is less than 0.01). Cluster-I (Khairi and Kabri), cluster-II (Hansli, Gujuri, Dumasil, Dhabla, Kalua and Khadia), cluster-III (Jhinjiria), and cluster-IV included Chitri populations. The maximum D2 value was found between Hansli and Kabri (513.825) followed by Gujuri and Kabri (410.312) while minimum D2 value was observed between Khairi and Kabri (1.50). The average inter cluster distance was high between cluster-I and cluster-II (17.218) and also between cluster-II and IV (17.207). The genetic variation can be confirmed using biochemical and DNA markers which will help to obtain phenotypically pure local fowl genetic resources for future selection and breeding.

Attaching and effacing Escherichia coli (AEEC) have been implicated in diarrhoea in humans in several countries. A total of 919 E. coli strains, isolated from 125 children with diarrhoea and 98 without diarrhoea, was investigated by PCR for the presence of the EAF, bfp, eae and stx genes. Thirty-four of these isolates were found to carry the eae gene; they were isolated from 27 (79.4 %) children with diarrhoea and seven (20.6 %) controls, in the city of Londrina, Brazil. These strains were investigated for their genotypic and phenotypic characteristics. Different genetic profiles were observed; strains containing the eae gene alone were most common (47.1 %). The characteristic genetic profile of typical enteropathogenic E. coli (EPEC), eae, bfp and EAF, was only found in isolates from children with diarrhoea. The stx gene was not detected in any of the 34 strains studied. Ten (29.4 %) strains were negative in the fluorescent actin-staining test. Localized adhesion (LA) was the most common pattern of adhesion (44.1 %), followed by the aggregative adhesion (AA) (23.5 %) and localized adhesion-like (LAL) (14.7 %) patterns. The results showed a strong association between strains presenting the LA pattern and diarrhoea. Forty-seven per cent of the strains studied belonged to classical O-serogroups of EPEC. The most common serotype found was O119 : H6; these isolates all showed the LA pattern, were positive for fluorescent actin-staining and were associated with diarrhoea. Intimin β was detected in seven strains, four of which belonged to serotype O119 : H6 and three to serotype ONT : H7; all were associated with diarrhoea. On the other hand, intimin ϵ was detected in two strains of serotype O111 : H38 and one of serotype ONT : H19, isolated from children without diarrhoea. To our knowledge, this is the first report of the occurrence of intimin ϵ in strains of E. coli isolated from humans in Brazil.

Raden I, Nugroho CC. Syahrani. 2017. Identification and characterization of morphological diversity of Lemba (Curculigo latifolia) in East Kalimantan, Indonesia. Biodiversitas 18: 1367-1376. Lemba (Curculigo latifolia) is Kalimantan’s land prospective for commercial cultivation because its leaf fiber has been traditionally utilized as fiber source for ulap doyo woven cloth; its fruit as sweetener; and its root as medicinal herb. To this days, only a few of research has been conducted on lemba in East Kalimantan or even in Indonesia, including studies on lemba plant phenotype suitable for weaving material. Thus, a research about identification and morphological characterization of lemba cultivars is necessary to identify and characterize lemba plant in East Kalimantan to reveal phenotypic variability in both quantitative and qualitative traits that can be utilized as the source of germplasm for the plant breeding program. This study was carried out in three Sub-districts, i.e.: Tenggarong Sub-district (Kutai Kartanegara District), Kota Bangun Subdistrict (Kutai Kartanegara District), and Jempang Sub-district (West Kutai District). Data collection was done by observation, and measurement of quantitative and qualitative traits of lemba plant. Descriptive analysis was applied on the morphological traits data, while correlation analysis was performed to reveal relationship between the qualitative and quantitative morphological traits by using software Minitab v.14.12. Phenotypic variability was determined based on the standard deviation. Principal component analysis and cluster analysis of the data were performed by using software SPSS v.11.6. The variance value of the 33 observed lemba plant accessions from the three Sub-districts indicated that the phenotypic variability of the qualitative traits was narrow while that of the quantitative traits was broad. There are three principal components that account for the observed variability with a cumulative variance of 96% which is obtained from 19 observed traits. Cluster analysis at similarity 95% indicates that there are five lemba accessions groups based on only qualitative, only quantitative, or based on combined qualitative and quantitative traits.

Fermented foods are consumed by a very large population in Africa but the products have many drawbacks ranging from shelf life instability to contamination and toxicity. These foods therefore require an upgrade through improved fermentation processes. This work determined the phenotypic characteristics of the fermenting microorganisms and microbial ecological succession during fermentation of cassava and maize to determine the predominant fermenting microorganisms. Cassava roots and maize grains were fermented using the traditional method of processing them into fufu and ogi for 72 h and 48 h respectively. Samples were drawn every 12 h for analysis. Enumeration and characterization of lactic acid bacteria were carried out on MRS medium with subsequent microscopic examination, physiological, biochemical reaction tests and API 50 CH gallery. Yeast isolates were identified by their morphological characteristics. Thirteen lactic acid bacteria were isolated from the fermenting cassava and 6 from the fermenting maize. The Isolates were Gram positive and catalase negative. Lactobacillus plantarum, L. fermentum and L. pentusus predominated in both fermentations while Candida tropicalis, C. krusei and Saccharomyces cerevisae also predominated in both fermentations. Candida inconspicuo was found only in cassava fermentation. The results of this work revealed the microbial ecology of fermented cassava and maize which is a prerequisite to the understanding needed to develop a multifunctional starter culture for these fermentations for their upgrade. Keywords: Cassava, Maize, Fermentation, lactic acid bacteria, Yeasts.
