Forty samples each of pork and chicken meat were collected from local retail markets in Khon Kaen, northeast Thailand, for Salmonella isolation and identification during 2003. Fifty-four isolates of Salmonella obtained from diarrheal patients admitted at a hospital located in the same town were serotyped. All isolates were also tested for antimicrobial sensitivity against amoxicillin (Amx), chl...

The melanocortin 1 receptor (MC1R) gene is related to the plumage color variations in chicken. Initially, the MC1R gene from 30 individuals was sequenced and nine polymorphisms were obtained. Of these, three and six single nucleotide polymorphisms (SNPs) were confirmed as synonymous and nonsynonymous mutations, respectively. Among these, three selected SNPs were genotyped using the restriction ...

Polydactyly, a common heritable limb malformation in vertebrates, is characterized by supernumerary digits. In chickens, basic characteristics and rough dominant genes have been explored in past decades; however, the elaborate pattern of inheritance and the determinant gene remain obscure. In this study, different types of polydactylism were classified by the numbers and the shapes of toes, inc...

We examined 29 isolates of Salmonella enterica subspecies enterica serovar Schwarzengrund from broiler chickens (n=19) and retail chicken meats (n=10) in Japan for antimicrobial susceptibility and pulsed-field gel electrophoresis (PFGE) profiling. All isolates exhibited resistance to both bicozamycin and sulfadimethoxine (minimum inhibitory concentration of both antimicrobial agents: >512 micro...

A total number of 330 native Libyan chicken eggs were collected from smallholders over different areas of south Libya to determine and classify some quantitative and qualitative traits in Libyan native fowls. The quantitative traits studied in the current trial were fertility and hatchability percent, egg weight, eggshell characteristics (weight, thickness, area), chicks weight and body measure...

In this paper a new general GP schema theory for headless chicken crossover and subtree mutation is presented. The theory gives an exact formulation for the expected number of instances of a schema at the next generation. The theory includes four main results: microscopic schema theorems for both headless chicken crossover and subtree mutation, and two corresponding macroscopic theorems. The mi...

BACKGROUND Staphylococcus aureus is one predominant cause of skin and soft-tissue infections (SSTIs), but little information exists regarding the characterization of S. aureus from non-native patients with SSTIs in China. METHODS In this study, we enrolled 52 non-native patients with S. aureus SSTIs, and 65 native control patients with S. aureus SSTIs in Shanghai. 52 and 65 S. aureus isolates...

Salmonella were isolated from 106 (0.032%) of 331,644 fecal samples from food handlers, and from 144 of 11,478 fecal samples from symptomatic patients in Japan to determine the incidence and features of Salmonella serovars among food handlers. S. enterica subspecies enterica serovar Infantis (S. serovar Infantis) was the dominant serovar (accounting for 48.1%), followed by S. serovar Corvallis,...

We have replaced the glutamic acid-165 at the active site of chicken triosephosphate isomerase with an aspartic acid residue using site-directed mutagenesis. Expression of the mutant protein in a strain of Escherichia coli that lacks the bacterial isomerase results in a complementation phenotype that is intermediate between strains that have no isomerase and strains that produce either the wild...

Twelve avian diseases are listed by the World Organisation for Animal Health (OIE), although more than 100 infectious diseases have been described in commercial poultry. This article summarises a recent assessment of the biosecurity risks posed by non-listed avian diseases associated with imports of chilled or frozen chicken meat and meat products into New Zealand. Following the guidelines desc...
