“…The ability to recover M. bovis from raw milk is well documented, especially from milk obtained from cattle residing in areas with a high regional prevalence of bovine tuberculosis (11,13). In Mexico, the incidence of bovine tuberculosis varies by region, with beef cattle in the northernmost states having the lowest prevalence at less than 2% (21). However, the prevalence of M. bovis in dairy cattle in Mexico is significantly higher, with an estimated infection rate in this population of 16 to 17% (15,17).…”

Recent outbreaks of human tuberculosis in the United States caused by Mycobacterium bovis have implicated cheese originating in Mexico as a source of these infections. A total of 203 samples of cheese originating inMexico were cultured, and M. bovis was recovered from one specimen. Therefore, M. bovis can be recovered from cheese and may be a source of human infections.Bovine tuberculosis, caused by Mycobacterium bovis, is a zoonotic disease that also affects humans. Although people are generally infected through the inhalation of droplet nuclei, a significant proportion of human cases involve extrapulmonary tuberculosis, presumably caused by the consumption of nonpasteurized milk or dairy products (23). Indeed, milk pasteurization requirements in the United States were developed to prevent many food-borne infections, including tuberculosis, botulism, and scarlet fever, caused by consuming contaminated milk or dairy products (5). With the implementation of strict pasteurization requirements and a mandatory control program for bovine tuberculosis in live animals, the incidence of M. bovis infections in cattle in the United States has decreased to an all-time low of less than 0.001% (1). Consequently, human cases of M. bovis infections in the United States have also declined (23). However, several reports have shown an elevated incidence of human tuberculosis due to M. bovis in certain regions of the United States (2,7,14). For example, a study in San Diego County, CA, found that 129 of 1,931 (6.7%) culture-positive tuberculosis cases in the County were due to M. bovis (14). A similar epidemiologic investigation in New York City also reported that 1% of culturepositive tuberculosis cases in this area were due to M. bovis (4). In both reports, patients of Hispanic ethnicity were especially at risk and approximately one-third of the cases occurred in children. In both instances, epidemiologic investigations indicated that the consumption of unpasteurized dairy products, including soft fresh cheese originating in Mexico may have accounted for these cases (4). Therefore, to investigate this possibility, a survey for the presence of M. bovis in fresh cheese products entering the United States from Mexico was initiated as a collaborative project between USDA-National Veterinary Services Laboratories (NVSL) and the California Animal Health and Food Safety Laboratories.A total of 203 cheese samples were collected from travelers entering California at the United States Customs and Border Protection Port in San Ysidro, San Diego, CA, from March through August 2005. All cheese samples had been purchased by individuals for private consumption and were being imported through noncommercial channels. Thus, whether these products were derived from pasteurized or unpasteurized milk is unknown. These samples were shipped to USDA-NVSL for mycobacterial culture. For this, 5-g portions of cheese were weighed, aseptically transferred into a sterile stomacher bag containing 45 ml of sterile 2% sodium citrate, and homogenized in a stomac...

Новая коронавирусная инфекция и туберкулез являются ведущими причинами смертности от инфекционных заболеваний в настоящее время. Несмотря на то что туберкулез не считается распространенным сопутствующим заболеванием при COVID-19, эти две респираторные патологии могут протекать одновременно в организме человека и влиять на клиническое течение друг друга. Целью исследования явилось изучение особенностей клинического течения COVID-19 у больных с сочетанной ТБ/ВИЧ-инфекцией. В исследование включены 198 человек, которые разделены на 3 группы: в 1-ю группу (n=102) вошли пациенты с коинфекцией ТБ/COVID-19/ВИЧ, во 2-ю группу (n=70) вошли пациенты с коинфекцией ТБ/COVID-19, в 3-ю группу (n=26) вошли пациенты с коинфекцией COVID-19/ВИЧ. Группы были сопоставимы по основным характеристикам. Статистическая обработка данных выполнена при помощи программы IBM SPSS. Установлено, что пациенты с ВИЧ-инфекцией реже жаловались на озноб, аносмию, слабость, а пациенты с туберкулезом -на кашель, головокружение и слабость. У пациентов с коинфекцией ТБ/ВИЧ/COVID-19 замечена тенденция к более тяжелому течению COVID-19, которое заключалось в частом присоединении вирусной пневмонии. Несмотря на это, у пациентов регистрировалась низкая потребность в респираторной поддержке. Получение новых результатов исследований в изучении особенности клинического течения COVID-19 у больных с сочетанной ТБ/ВИЧинфекцией должно помочь предотвратить ухудшение эпидемической ситуации по ТБ в регионах в условиях пандемии COVID-19. Ключевые слова: туберкулез, клиническая картина, коронавирусная инфекция (COVID-19), ВИЧ-инфекция, клиническое течение.
