Important Study

Roddey et al have reported an important study on the sensitivity and specificity of the Strep A OIA test compared with two culture techniques—5% sheep blood agar and Todd-Hewitt broth—in an office practice setting. They found the sensitivity and specificity of OIA as compared with sheep blood culture to be 91.4% and 95.6%, and compared with the broth method, 90.4% and 94.1%, respectively. They conclude that the OIA method is preferable for the majority of their patients, but recommend a throat culture be performed in cases with a negative OIA test.

Amperometric Method

The effects of chitosan on various metabolic and digestive processes in the animal body are an important to study because of the production quality for animal nutrition, healthcare, etc. The major known changes in the biochemical parameters of the animal liquids (by chitosan usage as feed additive) are the following: ratio of volatile and fatty acids, content of fat, mineral composition, etc. The aim of this study was to evaluate the total amount of water-soluble antioxidants (TAWSA) of feed additives based on chitosan and high protein concentrate of microbiological synthesis and to assess the effect of these feed additives on TAWSA values of sheep blood serum by amperometric method. Firstly, the antioxidant activity of feed components based on chitosan or/and a high-protein microbiological synthesis concentrate was studied in this work. Second, the experiments are carried out on 6 fistula animals to confirm the results of laboratory studies. Third, the determination of the total antioxidant activity of sheep blood by using chitosan additives (as the feed components) by amperometric method was carried out. A particular difference in antioxidant activity of the control and experimental samples of the sheep blood was established for the first time.

The Relationship

Since Forssman (1911) discovered a heterologous haemolysin obtained by immunising rabbit against guinea-pig organs—kidney, liver, etc.—and having the property of dissolving sheep blood corpuscles but not those of the guinea-pig, many authors have devoted their time to this subject, and to the elucidation of the relationship between antigen and antibody.

Randomized Design

BAP media is a medium used to distinguish pathogenic bacteria based on their hemolytic power on red blood cells. Staphyllococcus aureus is a bacterium that is able to emolate red blood cells with 3 types of hemolysis, namely α, β, γ, and δ. Usually BAP media is made by adding 5-10% sheep blood. Making BAP media using sheep blood has become a problem for several laboratories today, including health education laboratories. This is because the health education laboratory does not yet have a sheep farm, so it has not been able to procure sheep blood. The use of human blood as a substitute for sheep blood in making BAP media may be a solution, but it is not yet known whether there are differences in the growth and hemolysis of S. aureus bacteria on BAP media in sheep's blood and human blood. This research is an experimental study with a completely randomized design (CRD) of 3 replications which aims to determine whether there are differences in growth and hemolysis of bacteria S. aureus in BAP media of sheep blood and human blood groups A, B, AB, and O. The results showed that S. aureus bacteria could grow and show hemolysis in BAP media in sheep blood and human blood in groups A, B, AB, and O. The results of subsequent studies analyzed ANOVA using the software spss for windows with a significant level of 0.05. From the results of research and data analysis it can be concluded that S. aureus bacteria can grow and show hemolysis in BAP media of sheep blood and human blood groups A, B, AB and O, but there are significant differences in the number of S. aureus bacteria colonies grown in BAP media of sheep's blood and human blood groups A, B, AB and O.

Probable Role

Anaplasmosis of ruminants is a group of natural focal infections caused by bacteria from the genus Anaplasma of the Anaplasmataceae family. The main etiological agent of anaplasmosis in sheep, goats, and wild ruminants is Anaplasma ovis, which parasitizes in the erythrocytes of these animals. The purpose of this study was the finding and identification of Anaplasma spp. in the blood of small ruminants using genetic methods and obtaining data on the distribution of anaplasmosis in the Irkutsk region. 20 goat blood samples, 611 sheep blood samples and 209 Dermacentor nuttalli ticks from 12 districts of the Irkutsk region were examined for the presence of Anaplasma spp. Only one type of anaplasma, A. ovis, was found among the genotyped samples. A. ovis was found in the blood of sheep and goats in all of the studied districts of the Irkutsk region. The proportion of sheep blood samples containing anaplasma DNA varied from 30 % to 85 %, in goats – from 10 % to 100 % in different districts, and averaged 57.8 % in sheep and 55,0 % in goats. Frequency of infection of D. nuttalli ticks with A. ovis was 5.7 %. The nucleotide sequences of the samples detected in the blood of small ruminants on the territory of the Irkutsk region differed from each other by a single nucleotide substitution and were identical to the sequences of the type strain Haibei, as well as the sequences of A. ovis previously found in the blood of sheep from Mongolia, deer from China, and Dermacentor niveus and Dermacentor nuttalli ticks from China. These sequences were also identical to the sequences previously found in the blood of sheep from Altai and in Dermacentor nuttalli ticks from Tuva, which indicates the wide distribution of these A. ovis genovariants in Siberia and the probable role of D. nuttalli as a carrier of the agent of anaplasmosis of small ruminants in the Irkutsk region.

Antimicrobial susceptibility of 50 Neisseria meningitidis strains detected in Nova Scotia between 2004 and 2018 was determined. The isolates were cultured from sites that might prompt chemoprophylaxis (27 blood, 18 cerebrospinal fluid [CSF], 3 CSF–blood, and 2 conjunctiva). Minimal inhibitory concentrations (MICs) were determined to azithromycin, ciprofloxacin, minocycline, rifampin, trimethoprim–sulfamethoxazole, and penicillin G, using a diffusion gradient strip on Mueller–Hinton agar with 5% sheep blood in 5% CO2 for 20–24 hours. All isolates remained susceptible to azithromycin, ciprofloxacin, minocycline, and rifampin, but there was 26% resistance to trimethoprim–sulfamethoxazole. There was a rise in penicillin MIC of the isolates over the study period.
