Infeksi Streptococcus sp. pada Hewan
Streptococcus adalah salah sati group of bacteria yang dapat mengeinfeksi baniak species in this species and causes purpuric conditions seperti mastitis, metritis, polyarthritis and meningitis.
He collected the genera Streptococcus, Enterococcus and Peptostreptococcus. Types and pathogens of streptococcus. The organism is merupakan Gram-positive cocci, about 1.0 µm in diameter and sepersusun seperti rantai dalam panjang yang berda beda.
Stroptococcus species merupakan Catalase-negative, facultative anaerobic and non-motile bacteria. Streptococcus juga merupakan stable battery, Eta Nikukan Exibana Serum or culture medium Darah Pada.
Streptoccus pneumoniae (penyebab penaykit pneumonia) forms several heads that look like a bunch of pears. Pathogens flow memliki kapsula tebal and koloninya mucoid products. The bacteria cause pneumonia in Manusa, Guinea Pigs and Bangsa Tikus.
While enterococci of the genus Menudamana Streptococcus enteric are found in the human digestive system in the air. Bacteria Tersebut Menudaman opportunistic pathogens differ from Streprococcus species dalam dua hal:
- Ini bacteria are tolerant to Garam Empedu.
- Some insulation is removable.
While the type Peptostreptococcus indolicus is an anaerobic streptococcus, and the etiology of the bovine disease "summer mastitis"

common habitat
Streptococcus is widespread worldwide and is a commensal bacterium that lives in the lining of the upper respiratory tract and lower genitourinary tract.
Bacteria are spread by yang yang sudah and rentan pada dry process and dapat dapat dapat dalam dalam pasut pasut pada inang/induk semangnya. While the bacterium Enterococcus merupakan operturistik digests the pathogenic bacterium Yang hidup di chanalana.
THE KEY
- Late gram positive cocci
- Tidak is stable, he needs media Diperkaya
- Small colon, usually beta hemolysis, and transparent
- catalase negative
- Optional anaerobic, stationary
- Common bacteria of the mucosa of the foot
- Rentan dalam proesos utamakan atau surikanan
- Pyogenic infection in Menyebabka
Difference in Sterprtococcus bacteria
The laboratory should test for streptococci, hemolytic type, Lancefield and those with biochemistry.
Hemolysis type sheep/bovine blood agar
- Beta hemolysis (complete hemolysis) is characterized by the empty area of the colon.
- Alpha hemolysis (partial hemolysis or incomplete hemolysis), characterized by a brown area or a sunken area around the colon
- Gamma hemolysis shows no changes in the blood around the colon.
Lancefield Squad
Pengelompokan Lancefield Adala serological methods for Yang Barasan Pada Classification group, specifically Subtansi-C salt (polysaccharide) Pada Ding. Methods include:
- Ring Rain Test. Substance C dietary extract dengan asam atau panas dari Streptococcus sp. Antigens ini diextras give Lapisar selugu antisera with different specificities. A positive reaction is characterized by the formation of a white ring on the surface of the water, which is placed nearby for 30 minutes (see image 2).
- Latex agglutination test. Substansi C antisera specific for groups A through G (excluding group E) are commercially available. Latex suspension particles Melapisi Tiap Yang specific antibody group. Group antigen is enzymatic from streptococcal yang dizim. In the curd, the antigen is gradually mixed in the plate with the curd in each antibody suspension. A positive reaction, which usually occurs within a minute, is characterized by agglutination (see photo 3).

Diploma thesis in biochemistry
- Several products are now available to elucidate the biochemistry of streptococci and fungi
- Water biochemistry semperto dibukan untuk anmbedak Streptococcus Group C pada kuda.

Pathogenesis is pathogenisitas
Pyogenic Streptococcus has been associated with abscess formation, other suppurative conditions, and sepsis. Streptococcus beta hemolytic gymmune lebih pathogenic dari streptococcus alpha hemolytic.
Virulence factors include enzymes and exotoxins, streptolysin (hemolysin), hyaluronidase, DNase, NADase, streptokinase, and protease. Some important specific factors are not yet understood.
Polysaccharide capsule, factor Adala virulensi utama dari S. pyogenes, S. pneumoniae, then some strains, then some S. equi punya kemapuan of antiphagoses (mechanism suatu untuk mendingari phagosit immune salt) Protein M digging juga salt, porniogenes of SS. antiphagoses. Ketiadaan antiphagocytic factor is a transparent bacterial factor, but dimusnahkan dengan cepat oleh phagosit salt.
diagnostic procedures
Sejarah penyakat (anamnesia), tanda klinis, dan patologi adalah hal yang dapat mengonfirmasi secara identificatif infection streptococcus sp.
- Example of Streptococcus sangat rentan tepadan utamakan atau seguriganan en harus dikultur keliminya. Pus or exudates collected with a swab are stored in the transport vehicle if the sample can be processed quickly.
- Polymerase chain reaction (PCR) sensitization techniques are used.
- Gram-positive ratai coccus can be seen under the microscope
- Diculture Best Pada Agar Darah, Selective Blood Agar and Mac Concey Agar. Plaat di incubasi secara arobik pada suhu 37 degrees Celsius Selama 24 sampai 48 am.
- Criteria for isolation identification:
- Colony Kecil, transparent, beberpa dapat menjadi mucoide
- Blood agar type hemolytic pada
- Ranta coccus gram positive
- Use MacConcey Agar, Enterococcus faecalis
- Your negative catalase
- Pengelompokan Lancefield (Lancefield Group)
- Biochemical profiles
the clinic of infections
Streptococcus bacteria hidup secara komesal pada membrane mucosa en sebagai akibatnya, infection banyak streptococcus beit opertunistik. Primary infections such as strangulation or secondary infections caused by viral infections such as Streptococcus pneumoniae.
Lymph nodes, ductal ducts or mammary glands may be infected. Neonatal sepsis wat diakibatkan oleh infection kasalana kelamin pada induk.
Streptococcus pyogenes, a human pathogen, causes Pada sapi mastitis, Pada Anjing tonsillitis, and Pada Muda lymphangitis.
The release of Streptococcus oada is still very limited, with the exception of S. suis, which can cause serious infections in people with children. Streptococcus bini, dapat mneyebabkan penyakat pada Bayi (Manusia), and kaatan jelas pada hewan dalam sampum stam ini.

Streptococus canis, the yang pathogen, means Anjing and is often associated with neonatal sepsis, suppurative conditions and toxic Syok syndrome.
Sesak nafas (suffocation), porcine streptococcal meningitis and bovine adalah streptococcal mastitis specific yang infection. The vaccine used to fight streptococci is usually less effective. The clinical consequences of streptococcal infection are shown in Table 1.
