Streptococcus Pyogenes: A Versatile Human Pathogen, Maria E. Cevallos
Streptococcus Pyogenes: A Versatile Human Pathogen, Maria E. Cevallos
Mako: NSU Undergraduate Student Journal
Streptococcus pyogenes is one of the most medically relevant genera of Gram positive bacteria. S. pyogenes belongs to Group A streptococcus (GAS), the most pathogenic streptococci. S. pyogenes is exclusively a human pathogen that is known for its ability to cause a wide array of infections ranging from superficial pharyngitis and impetigo to invasive life threatening conditions including septicemia, necrotizing fasciitis, and streptococcal toxic shock syndrome. The dissemination of S. pyogenes within a human host is dependent upon virulence factors aimed at host immune system evasion leading to infection. More specifically, S. pyogenes’ virulence factors are required for bacterial …
Methods Used By Dr. R. K. Benjamin, And Other Mycologists, To Isolate Zygomycetes, Gerald L. Benny
Methods Used By Dr. R. K. Benjamin, And Other Mycologists, To Isolate Zygomycetes, Gerald L. Benny
Aliso: A Journal of Systematic and Floristic Botany
The methods that Dr. Richard K. Benjamin used to isolate Zygomycetes are discussed. These processes involved the following five steps: (1) collection, (2) plating, (3) isolation, (4) culture, and (5) maintenance. Additional methods, materials, and modifications used to isolate Zygomycetes are summarized. The author considers the flattening of the aerial hyphae onto the substrate of the faster- and higher-growing Mucorales for several consecutive days to be the critical step in isolating species of Coemansia, Piptocephalis, Syncephalis, and Dimargaritales. The methods used by other scholars to isolate, culture, and study many taxa in Zygomycetes also are discussed.
Cryosurgical Treatment Of Anal Sac Fistulae In Dogs, Mehmet Sağlam, Ümi̇t Kaya
Cryosurgical Treatment Of Anal Sac Fistulae In Dogs, Mehmet Sağlam, Ümi̇t Kaya
Turkish Journal of Veterinary & Animal Sciences
Seven dogs of different breed, age, and sex that were diagnosed with anal sac fistulae upon clinical examination constituted the study material. Sedation for the procedure was maintained by means of xylazine hydrochloride administered intramuscularly. The patients were placed in the lateral recumbency position for the insertion into the fistulae of an appropriate probe, selected according to the lesion. Rapid cooling and spontaneous thawing were performed. This procedure was performed twice consecutively. The cooling temperature was adjusted to between -30 and -50 °C. The lesion healed completely between weeks 3 and 6 following the demarcation of necrotic tissue and growth …

Behavior Of An Escolar Lepidocybium Flavobrunneum In The Windward Passage As Determined By Popup Satellite Archival Tagging, D.W. Kerstetter, P.H. Rice, E.D. Prince
Behavior Of An Escolar Lepidocybium Flavobrunneum In The Windward Passage As Determined By Popup Satellite Archival Tagging, D.W. Kerstetter, P.H. Rice, E.D. Prince
Gulf and Caribbean Research
In June 2003, fisheries research was conducted in the Windward Passage using a chartered commercial pelagic longline vessel (Rice and Snodgrass 2003). This paper describes the habitat use by an escolar in this location tagged with a pop-up satellite archival tag (PSAT) that remained attached to the fish for 14 d. Data recovered from the PSAT were used to directly document diel vertical migration and ambient temperature range for the first time in a mesopelagic teleost.

Turkish Journal of Zoology
The Greater Noctule, Nyctalus lasiopterus, was recorded from southwestern Turkey for the third time. The dorsal fur of the Greater Noctule, which also covers the underpart of the wing membrane, along with the forearm and propatagium, is uniformly dark brown. The cranium shows typical characteristics of the noctule bats. In addition to these, the exoccipital is convex and is markedly visible in the planar view of the skull. There is a small depression mid braincase. The dental formula is i: 2, c: 1, pm: 1, m: 3/i: 3, c: 1, pm: 2, m: 3 = 32. The diploid number of …
