The following experiments constitute an attempt to follow out in detail the stages by which immunity is established, in the course of a generalised bacterial infection (Pseudotuberculosis of rabbits). Two aspects of immunity are considered, firstly the presence, in the circulating fluids, of specific antibacterial substances, and secondly the power of rapidly producing such substances in answer to the specific stimulus. That is to say, attention is directed, not only to the quantity of specific antibodies present on any day of the disease, but also to the response which the animal can make to various doses of bacterial vaccine. For the immune animal is both more vigorous and more sensitive than the normal, in its reaction to a renewed dose of poison (Wassermann and Citron, 1905). Naturally the facts established with regard to one disease only, cannot be predicated at once of other diseases, in other animals. Still it is hoped that the systematic study of one disease may give some help in coordinating the large but somewhat disjointed mass of clinical observation which is already available.

ABSTRACT CD21/35−/− mice, deficient in CD21 and CD35 (complement receptors 2 and 1, respectively), were infected with Borrelia burgdorferi to assess the role of these receptors in a chronic bacterial infection. Although CD21/35−/− mice on both C57BL/6 and BALB/c backgrounds produced less B. burgdorferi-specific antibodies than did wild-type mice, spirochete levels and arthritis severity were similar.

A study on clinical observation, management and complication of foot and mouth disease (FMD) outbreak in cattle was carried out in Chuadanga sadar upazilla during 24 weeks period from July 2012 to January 2013. Clinical data were collected from 108 cattle of both sexes. The effect of season, breed, age, sex and purpose of keeping cattle on the incidence of the disease was analyzed. Seasonal variation of the disease was significant. Crossbred was found to be more susceptible than local breed. The prevalence of the disease was found significantly higher in male than female. The clinical prevalence of FMD increased in the month of November (31.48%). The prevalence of FMD in other months varies from 5-21%. Clinical observation of FMD affected cattle showed fever, anorexia, salivation and erosive lesion on oral mucosa and inter digital region of foot. Antibacterial drug could be recommended for clinical practice to control secondary bacterial infection in complicated FMD cases.

Nearly seventy percent of all children between the ages of one week and two-years-ofageare brought to Kanti Children’s Hospital for some type of febrile episode. And50% of these visits are for temperatures greater than or equal to 39 degrees celsius.These children may have significant bacterial infection. In 35% of these childrenthere’s no definable source for the fever on clinical examination. So the child thatdon’t have identifiable sources could be either bacteremic, meningitis or could have abone or joint infection in evolution. Simple clinical observation to differentiate a welllooking infant from a toxic infant helps to differentiate children who needs admissonor out patient follow-up.Key Words: Fever, young infant, antibiotics, management.

An experiment to evaluate the efficacy of inactivated polyvalent bacterial vaccines to increase specific immunity of tiger grouper (Epinephelus fuscoguttatus) against bacterial infection was conducted in floating net cages located in Sumbawa Island, West Nusa Tenggara. Polyvalent bacterial vaccine was prepared by mixing three species of killed-bacteria (Vibrio harveyi, V. alginolyticus, and Photobacterium leiognathi) with ratio of 1:1:1. The density of bacterial vaccine was adjusted at 1010 CFU/ml. The vaccines were delivered by immersion. The control fish were immersed in sea water without vaccine. Fish with ± 6 cm of total length and ± 7 g of body weigth were used in this experiment. The fishes were reared in concrete tanks in hatchery of Gondol, Bali until they reached ± 9 cm of total length. Later, the fishes were reared for 6 months in floating net cages located in Sumbawa. Re-vaccinations were delivered 60 days and 120 days post initial vaccination. The results showed that titer antibody and survival rate of the vaccinated fish were 1/128 and 77.11%, higher than the control (titer antibody=1/4-1/8, survival=45.56%, respectively). The relative percent survival of the vaccinated fish was 57.95%. It was suggested that the vaccines were immunogenic and had protective ability against bacterial infection in tiger groupers. Keywords: bacterial disease, polyvalent bacterial vaccine, tiger grouper

Abstract Strong discrepancies in published data on the levels and epitope specificities of antibodies against the xenogenic N-glycolyl forms of sialoglycans (Hanganutziu-Deicher Neu5Gcɑ2-3Galβ1-4Glc and related antigens) in healthy donors prompted us to carry out a systematic study in this area using the printed glycan array and other methods. This article summarizes and discusses our published and previously unpublished data, as well as publicly available data from the Consortium for Functional Glycomics. As a result, we conclude that (1) the level of antibodies referred to as anti-Neu5Gc in healthy individuals is low; (2) there are antibodies that seem to interact with Neu5Gc-containing epitopes, but in fact they recognize internal fragments of Neu5Gc-containing glycans (without sialic acids), which served as antigens in the assays used and; (3) a population capable of interacting specifically with Neu5Gc (it does not bind the corresponding NAc analogs) does exist, but it binds the monosaccharide Neu5Gc better than the entire glycans containing it. In other words, in healthy donors, there are populations of antibodies capable of binding the Neu5Gc monosaccharide or the inner core -Galβ1-4Glc, but very few true anti-Neu5Gcɑ2-3Galβ1-4Glc antibodies, i.e., antibodies capable of specifically recognizing the entire trisaccharide.

Autoimmune gastritis remains an insufficiently studied disease with an unknown prevalence and nonspecific clinical picture. Autoimmune gastritis is associated with other autoimmune diseases and characterized by an increased risk of developing neuroendocrine and epithelial tumors of the stomach. The diagnostic criteria for autoimmune gastritis are not clearly defined, the diagnosis is based on the detection of specific antibodies and morphological verification, while the value of intraluminal endoscopy has not been established. The article describes the characteristic signs of autoimmune gastritis, detected during routine endoscopic examination and with the use of magnifying and narrow-spectrum imaging. The clinical observation is presented.

The understanding of ribosome structure has advanced considerably in the last several years. Biochemists have characterized the constituent proteins and rRNA's of ribosomes. Complete sequences have been determined for some ribosomal proteins and specific antibodies have been prepared against all E. coli small subunit proteins. In addition, a number of naturally occuring systems of three dimensional ribosome crystals which are suitable for structural studies have been observed in eukaryotes. Although the crystals are, in general, too small for X-ray diffraction, their size is ideal for electron microscopy.

As interest for parallel EELS spectrum imaging grows in laboratories equipped with commercial spectrometers, different approaches were used in recent years by a few research groups in the development of the technique of spectrum imaging as reported in the literature. Either by controlling, with a personal computer both the microsope and the spectrometer or using more powerful workstations interfaced to conventional multichannel analysers with commercially available programs to control the microscope and the spectrometer, spectrum images can now be obtained. Work on the limits of the technique, in terms of the quantitative performance was reported, however, by the present author where a systematic study of artifacts detection limits, statistical errors as a function of desired spatial resolution and range of chemical elements to be studied in a map was carried out The aim of the present paper is to show an application of quantitative parallel EELS spectrum imaging where statistical analysis is performed at each pixel and interpretation is carried out using criteria established from the statistical analysis and variations in composition are analyzed with the help of information retreived from t/γ maps so that artifacts are avoided.
