BACKGROUND: The early stage of Copper poisoning is difficult to be clinically diagnosed in sheep and has not been documented clearly yet. OBJECTIVES: To assess biomarkers in predicting early Copper poisoning in sheep, blood samples were collected from several groups of animals from a naturally Copper poisoning occurrence in an industrial region. METHODS: Animals were divided into four experimen...

Microbial infection of the amniotic fluid is a significant cause of fetal injury, preterm birth, and newborn infections. Group B Streptococcus (GBS) is an important human bacterial pathogen associated with preterm birth, fetal injury, and neonatal mortality. Although GBS has been isolated from amniotic fluid of women in preterm labor, mechanisms of in utero infection remain unknown. Previous st...

A test is described that could replace bacitracin susceptibility for presumptive identification of group A streptococci as well as 6.5% NaCl agar tolerance for presumptive identification of enterococcal streptococci. The L-pyrrolidonyl-beta-naphthylamide test, based on hydrolysis of pyrrolidonyl-beta-naphthylamide, was used in conjunction with the CAMP and bile-esculin tests to presumptively id...

Wit/i the assistance of KATHRYN BEAVFIE T HE SUB.JECT of this report is an unusual experiment of nature imivolving a pair of twins of different A and B blood groups bormi to a group 0 mother. The devebopmemit of frank hemolytic disease in the twin hebongimig to blood group B, in the absence of recognizable abmiormalities imi the group A twin was the indication for a detailed study of the behavi...

Acute tonsillopharyngitis is a very common upper respiratory tract infection and might cause serious morbidity and even mortality if not handled properly. Although the etiologic agent is mostly viral, group A beta hemolytic streptococcus is the most important bacterial agent, with a frequency of 15-30% in the pediatric age group. In this article, as the social burden for this infection is notab...

Varicella is generally a benign, self-limited childhood illness; however, severe, life-threatening complications do occur. A live, attenuated vaccine exists to prevent this illness, but controversy remains concerning the need to vaccinate children for what is generally a benign, self-limited disease, although more states are currently recommending this vaccine. We report a previously healthy 3-...

Meritec-Strep (Meridian Diagnostics, Inc., Cincinnati, Ohio) a coagglutination method, was compared with Streptex (Wellcome Diagnostics, Research Triangle Park, N.C.), a latex agglutination method, for the identification of beta-hemolytic streptococcal groups A, B, C, F, and G by the direct colony method. A total of 124 beta-hemolytic streptococcal isolates were tested, which included 77 from g...

Oral Campylobacter species are rarely reported to cause extraoral infections. Here we present three cases of extraoral abscess caused by an oral Campylobacter sp. and a Streptococcus sp. The Campylobacter species were all isolated anaerobically and identified by sequencing analysis of the 16S rRNA gene. The cases included a breast abscess caused by Campylobacter rectus and a non-group A beta-he...

Blood group antigens (BGAs) can act as functional molecules but also can evoke autoantibodies and alloantibodies, causing autoimmune hemolytic anemia, hemolytic disease of the newborn and hemolytic transfusion reactions. In Section I, Dr. Marilyn Telen discusses physiologic and pathologic functions of RBC BGA-bearing molecules. She reviews some associations of BGAs with RBC membrane integrity a...

Skin and Soft Tissue Infections (SSTI) resulting from cat bites most commonly occur due to Pasteurella infection. However, other pathogens such as Β-Hemolytic Streptococci
