概括
巴西的一次炎爆发与未经巴氏消毒的奶酪中的Streptococcus equi subspecies zooepidemicus有关. 这凸显了食用未经巴氏消毒的乳制品的风险以及对食品安全的需求.
科学领域:
- 传染病流行病学 传染病流行病学
- 食物传播疾病 食物传播疾病

背景情况:
- 急性炎的爆发很少见,但在1997年12月至1998年7月期间,在巴西诺瓦塞拉纳发生了显著的集群.
- 疫情影响了253人,其中7人需要透析,3人死亡,需要对其原因进行调查.
研究的目的:
- 为了确定在巴西诺瓦塞拉纳的急性炎疫情的致病原体和传播途径.
- 调查炎病例与当地乳制品消费之间的关联.
主要方法:
- 进行了一项匹配的病例控制研究,涉及病例家庭,他们的家庭成员和匹配的控制家庭.
- 与患者的采访和对照集中在乳制品消费上,补充了乳制品和牛样本的微生物分析.
主要成果:
- 喉培养物将炎与Streptococcus equi subspecies zooepidemicus (S. zooepidemicus) 联系起来,这种细菌已知会引起牛乳腺炎.
- 摄入当地生产的未经巴氏杀菌的奶酪 (queijo fresco) 与炎有显著的相关性 (匹配的几率比为2.1,p=0.05).
- 爆发的S. zooepidemicus菌株是从供应非巴氏化奶酪的农场的奶酪制造人员中分离出来的,并且在从分销中删除后没有报告新的病例.

Types of Fever
Fever can be triggered by several factors, including infections, nervous system disorders, certain cancers, blood diseases like leukemia, embolism, thrombosis, heatstroke, dehydration, surgical trauma, crushing injuries, and allergic reactions.
Here are the different types of fever:
Here are the different types of fever:
Rocky Mountain Spotted Fever
Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
Bacterial Meningitis
Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...
Viral Meningitis
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
Arboviral Encephalitis
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
American Trypanosomiasis
Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
