Prevalensi Strain Avian Pathogenic Escherichia coli (APEC) Penyebab Kolibasilosis pada Burung Puyuh

Avian Pathogenic Escherichia coli (APEC) is a pathogen that causes colibacillosis in poultry, including salpingitis, omphalitis, cellulitis, swollen head syndrome, coligranuloma yolk sac inflammation, and air sacs inflammation. APEC is a zoonotic strain which spread through raw meat and processed meat products of animals and birds. In this research, the isolation and identification of Escherichia coli were done by using selective media MacConkey, Kligger Iron Agar, and Gram staining. Polymerase chain reaction (PCR) was used to analyse genetopically to detect 16SrRNA genes, vt1 genes, and vt2 genes. Thirty one (55,36%) isolates of 56 specimens collected from quail were detected as Escherichia coli. The detection of APEC strains towards 31 Escherichia coli isolates were done by using polymerase chain reaction (PCR) with vt1 and vt2 specific primer. The results showed that 32,26% (10/31) was APEC strains and 67.74% was non-APEC strains. From 10 isolates, 90% had vt1 gene and 10% had vt2 gene. Escherichia coli isolates were found in eyes (32,26%), infraorbital sinus fluid (32,26%), nasal fluid (16,20%), also in lungs, air sacs, ascites, and heart for 3,2% each. The isolates could not be found in the specimens from the skull. As a zoonotic agent, the isolates have an impact on human health.

Genetic Determination and Clonal Relationships of Staphylococcus aureus Isolated from Dairy Cows in Baturraden, Central Java, Indonesia

Cases of mastitis in cows at Baturraden are leading to signifi cant and ongoing problems due to reducedproduction and lower milk quality. This study was designed to identify which of selected virulence determinantgenes of S. aureus are involved in the Baturraden infection, and to determine the clonal relationship amongthese isolates. Seventeen isolates were identifi ed as S. aureus based on their biochemical properties and speciesspecifi city for 23S rRNA and nuc genes. S. aureus isolates were genotypically characterized for the selectedvirulence determinants: coa, clfA, fnbA, fnbB, cap5, spa IgG and spa X- region genes. Clonal relationship analysisamong isolates was carried out using AFLP and results compared with previously confi rmed relationshipsbetween selected S. aureus isolated from other regions. The results show that eight isolates contain all thegenes, but six isolates lack fnbB and two isolates lack cap5 genes. AFLP analysis showed that all isolates of S.aureus originating from cows in Baturraden belong to one cluster. This study provides additional knowledgeabout S. aureus infection in Baturraden cows, including the number of virulence determinant genes that mayplay a role in pathogenicity

The aims of the research were to evaluate resistance of Staphylococcus aureus against several antibiotics and to detect the gene encoding ofmethicillin resistant Staphylococcus aureus (MRSA) in broiler. Twenty three Staphylococcus aureus isolated from infected broiler in Yogyakartawere used. Genotypic identifications were done based on the occurrence of gene nuc and 23SrRNA. The resistance assay to several antibioticsrevealed that Staphylococcus aureus were resistant to penicillin 78% (18/23), doxycyclin 56% (15/23), gentamicin 26% (6/23), tetracyclin 22% (5/23), erythromycin 13% (3/23), and methicillin 9% (2/23). Detection of gene encoding MRSA on 23 isolats of S. aureus showed that 8 (34.8%) isolates contain gene mecA.Key words: Staphylococcus aureus, broiler, resistant, methicillin, mecA

Karakterisasi Faktor-faktor Virulensi Staphylococcus Aureus Asal Susu Kambing Peranakan Ettawa Secara Fenotip Dan Genotip

Staphylococcus aureus is a major cause of mastitis in large or small ruminants, and often manifested by subclinical mastitis in Peranakan Ettawa (PE) goats. Staphylococcus aureus in human can cause food borne disease. The research aimed to characterize the virulence factors of Staphylococcus aureus isolated from milk PE goats, phenotypic- and genotypically. Phenotypically characterization were determined through the pigmen assay as well as hydrophobicity, haemolysin, and hemaglutinin reaction. Polymerase chain reaction (PCR) analysis was used to detect 4 virulen genes including coa, clf, fnbA, and fnbB genes. The results of research showed that Staphylococcus aureus abled to produce white pigmen (35,7%), yellow pigmen g (57,1%), andorange pigmen (7,2%). Staphylococcus aureus showed α-hemolysis zone (35,7%), β-hemolysis (35,7%), dan γ-hemolysis (28,9%). Hydrophobicytic test revealed 14,3% Staphylococcus aureus isolates were hydrophobe and85,7% hydrophil. Staphylococcus aureus (85,7%) isolates abled to aglutinated sheep blood cells. Based on genotypic analysis of Staphylococcus aureus could be detected coa gene (92,8%), clf gene (64,3%), fnbA gene (78,6%), and fnbB gene (64,3%). Based on the phenotypic and genotypic characters, it can be concluded that Staphylococcus aureus are virulent strains. This information can be used as the basis for control mastitis in PE goat

Potensi Ekstrak Daun Sage (Salvia Officinalis.L) Sebagai Anti-Streptococcus Suis Penyebab Zoonotik Meningitis

The phenomenon of microbial resistance to an antibiotic or some kind of specific antibiotics (multi drugs resistance) greatly complicate the treatment process, one of which is Streptococcus suis (S. suis) which is known to cause meningitis in animals and humans. Today, with rising bacterial resistance to a wide rangeof antibiotics, it takes an effort to assess the potential medicinal plants as an antibiotic that is appropriate and safe. Sage (Salvia officinalis.L) is reported to have antibacterial and fungicidal effect. Phenolic acids such assalvin and ether monomethyl salvin which isolated from the sage thought to have antimicrobial activity against several bacterial strains. The purpose of this study was to prove the ability of sage leaf extract as an antibacterialagainst S. suis causes streptococcal meningitis in vitro. In-vitro method used in this research through a two-stage dilution test and the diffusion test on Mueller Hinton Agar (MHA). S. suis isolates (code 225) were tested in vitro against 8 levels sage leaf extract concentration, ie a concentration of 1%, 3% 5%, 7%, 10%, 20%, 40% and 60%. The results of the test obtained by minimum inhibitory concentrations (MICs) and minimum sage known to potentially inhibit the growth of S. suis
