Bovine tuberculosis is a zoonotic disease which should be emphasized in our country as in many countries. A large number of genotypes have been revealed by spoligotyping method of M. bovis in the world. M. bovis SIT 482. BOV is one of these genotypes and it is also M. bovis genotype in which BCG vaccine is administered in humans. The BCG vaccine is obtained through multiple passages of this genotype. However, this genotype, like other genotypes, can cause serious infections in humans and animals. There are data on the isolation of M. bovis SIT 482 BOV from animal and human tuberculosis cases in the world. In our country, the isolation of this genotype has been reported only in humans and no data have been found in the animals. In this study, M. bovis SIT 482. BOV was isolated from the samples of six cattle with internal organ samples obtained from licensed slaughterhouses in Aksaray. While isolation is carried out with BACTEC MGIT 960 liquid media, spoligotyping was carried out according to the manufacturer’s with kit (Isogen LifeScience, The Netherlands). This study aims to report M. bovis SIT 482 BOV from cattle in Turkey for the first time, to draw attention a very limited number reported in M. bovis cases in Turkey, highlight the importance of genotyping of tuberculosis factors and contribute to epidemiological studies. These and similar studies will contribute to the creation of genetic maps for eradication of M. bovis from cattle in our country. The study was also conducted to investigate whether M. bovis SIT 482. BOV isolated from cattle in Aksaray province is BCG strain or another strain giving the same pattern.

Acinetobacter baumannii has emerged as an important pathogen related to serious infections and nosocomial outbreaks around the world. The aim of this study was to detect the distribution of carbapenemases and efflux pump in carbopenems-resistance Acinetobacter baumannii(CRAB). In this study, 100 isolates of CRAB were collected from clinical specimens. Agar dilution was conducted to determine the minimum inhibitory concentrations (MICs) to 15 kinds of antibiotic. Genes of carbapenemases and efflux pumps were amplified by PCR. The expression difference of pump genes was also analyzed by real-time PCR between CRAB and carbopenems- sensitive Acinetobacter baumannii (CSAB). We found that most antibiotics, including aminoglycosides, fluoroquinolones and cephalosporins showed high MIC values in CRAB. While, all isolates were sensitive to polymyxin B. Among CRAB, 54, 32 and 16 isolates were positive for SHV-12，PER-1 and TEM-1, respectively. 86 isolates were positive for OXA-23. 55, 33 and 5 isolates carried adeB, adeJ and adeE genes. The expression level of adeB in CRAB was ten times higher than that in CSAB. Moreover, isolates with single adeE gene were detected for the first time in Acinetobacter baumannii.

BCG (Bacillus Calmette-Guerin) vaccine was developed from an attenuated strain of Mycobacterium bovis at the beginning of the twentieth century. Its widespread use as a vaccine against tuberculosis spread in Europe, and subsequently globally, over the next 50 years. It remains one of the most frequently administered vaccines in the world. It has also been one of the most controversial. Widely differing estimates of the effectiveness of BCG at protecting against different forms of tuberculosis in different population subgroups in different settings have been published [1]. Some countries, with a low incidence of tuberculosis, did not adopt the use of BCG vaccine at all and some others abandoned its use at a later stage. In addition, great variation developed in national programmes for the administration of BCG including the age(s) at which it should be given, whether or not its administration should be preceded by tuberculin sensitivity testing, and whether repeat vaccinations with BCG should be given.

Mycobacterium bovisis the major causative agent of bovine tuberculosis, one of the most relevant zoonoses in the world, and affects a wide range of wild and domesticated animals. Development of screening panels in mycobacterial genotyping, according to specific geographical regions, is strongly needed. The aim of this study is to select a panel, constituted by highly polymorphic MIRU-VNTRloci, to discriminate clinical isolates ofM. bovisin Mexico. In this study, 65 isolates ofM. bovisobtained from clinical bovine samples proceeding from different geographic regions of Mexico were identified by phenotypic and genotypic tests and subsequently genotyped by a 24-locusMIRU-VNTR panel. The most polymorphiclociwere selected to build a panel with a high discriminatory power similar to the 24-locuspanel results. A panel of seven elements (QUB 11a, MIRU 26, ETR-A, QUB 26, MIRU 16, MIRU 27, and MIRU 39) with the highest allelic diversity showed an appropriate differentiation. The selected MIRU-VNTR elements, according to the regional allelic variability, may be used in the preliminary genotyping ofMycobacterium bovisisolates in Mexico.

INTRODUCTION: India being the second highly populated nation in the world. HIV/AIDS has acquired pandemic proportion in the world. Estimate by WHO for current infection rate in Asia. India has the third largest HIV epidemic in the world. HIV prevalence in the age group 15-49 yrs was an estimate of 0.2%. India has been classified as an intermediate in the Hepatitis B Virus (HBV) endemic (HBsAg carriage 2-7%) zone with the second largest global pool of chronic HBV infections. Safety assessment of the blood supply, the quality of screening measures and the risk of transfusion transmitted infectious diseases (TTIs) in any country can be estimated by scrutinizing the files of blood donors. After the introduction of the blood banks and improved storage facilities, it became more extensively used. Blood is one of the major sources of TTIs like hepatitis B, hepatitis C, HIV, syphilis, and many other blood borne diseases. Disclosure of these threats brought a dramatic change in attitude of physicians and patients about blood transfusion. The objective of this study is to determine the seroprevalence of transfusion transmitted infections amidst voluntary blood donors at a rural tertiary healthcare teaching hospital in Chhattisgarh. MATERIAL AND METHODS: This retrospective study was carried out in Chandulal Chandrakar Memorial Medical College, Kachandur, Durg. Blood donors were volunteers, or and commercial donors who donated the blood and paid by patients, their families, or friends to replace blood used or expected to be used for patients from the blood bank of the hospital. After proper donation of blood routine screening of blood was carried out according to standard protocol. Laboratory diagnosis of HIV 1 and HIV 2 was carried out by ELISA test. Hepatitis B surface antigen was screened by using ELISA. RESULTS: A total of 1915 consecutive blood donors’ sera were screened at Chandulal Chandrakar Memorial Medical College, blood bank during study period. Of these 1914 were male and 1 female. The mean age of patients was found to be 29.34 years with standard deviation (SD) of 11.65 Years. Among all blood donors in present study, 759(39.63%) were first time donors and 1156(60.37%) were repeated donors. 1 patient was HIV positive in first donation group while 3 (75%) were positive in repeat donation group. 7 (38.9%) were HBsAg positive in in first donation group while 11(61.1%) were positive in repeat donation group. Two patients in first donation group had dual infection of HIV and HBsAg. CONCLUSION: Seropositivity was high in repeated donors as compared to first time donors. The incidence of HIV is observed to be 0.2% and that of HBsAg is 0.94%. Strict selection of blood donors should be done to avoid transfusion-transmissible infections during the window period.

The author of the article discloses the prospects of development of the world feed production for aquaculture based on the analysis of key innovative technological and market trends. The author specifies that shortage, high cost, low ecological compatibility of traditional raw materials - fish flour - are among major limiting factors in the development of production of feeds for aquaculture. This fact, in turn, limits sustainable development of aquaculture both in Russia, and in the world in general. The article presents the overview of a current status of the world industry of feed production in aquaculture, where the regional situation is studied, as well. For the first time, there is given the outlook of innovative technologies in feed production based on the alternative sources of protein (on the example of projects of leading aquabiotechnological companies) which will determine industry’s objectives for the mid-term perspective.
