The rod-shaped bacteria that killed a Missouri infant this month have
infected at least 120 infants worldwide since 1958 and have been linked to
the use of baby formula in the past, public-health researchers say.
The potential for the bacteria, called Cronobacter, to infect infants
through powdered baby formula has only been known since the 1980s, said
Kieran Jordan, a microbiologist at the Moorepark Food Research Centre of

发帖数: 171 | 2 怀孕期间得了yeast infection,因为搬家换OB，一段时间没拿到原来的病例新OB不接见
，耽误了很久才看，好了又犯，很痛苦。 然后查出来又有bacteria infection, 两种
bacteria, 名字记不清了，吃了两种抗生素一周。过不久又痒，最近查不来好像
bacteria没杀死。
怀孕期间什么药都不想吃，结果不得不吃抗生素，实在不想吃两次。 而且吃了抗生素
，yeast infection又要加重，完后又给bacteria生存的环境。 快疯了。
记得版上提过yeast infection晚上把蒜瓣放进阴道，试过一次，好了又复发。
版上姐妹们有任何人有这方面的经验或者知识吗？无论如何不想吃抗生素了。 好像这
个bacteria infection在孩子出生时可能会造成感染，也很可怕。
提前谢谢各位。
更新一下： 问了OB，原来不管它们尤其是bacteria并不会造成生产对宝宝的感染，护
士上次没问OB就告诉我会造成生产对宝宝的感染，让我怀孕期间吃抗生素，我还是很不
满的。 所以选择暂时不管bacteria，先把yeast infection治好再说。 |

Salmonella is a type of bacteria. It is usually found in poultry, eggs,
unprocessed milk and in meat and water. It may also be carried by pets like
turtles and birds.
What kind of infection does salmonella cause?
The salmonella bacteria attacks the stomach and intestines. In more serious
cases, the bacteria may enter the lymph tracts, which carry water and

发帖数: 692 | 4 三天前宝宝腹股沟长了一个小脓包，在大家的建议（原贴在下面）下带去看医生，给了
些antibiotic药膏，为了保险起见做了个culture。周末涂了药，脓出来了伤口也已经
好了。今天突然收到医院电话，说化验有bacteria，让马上开始吃抗生素十天。挺紧张
的，有几个问题不明白：
1。什么原因会引起bacteria？起包前一天打了四个月疫苗。上星期我着凉了感冒但都
是戴口罩才接触宝宝。不知这两件事会是诱因吗？
2。化验有可能错吗？做culture时看护士就随便拿棉签这么一抹，会不会其实是外界的
bacteria? 后悔当时着急，没等医生就看了nurse practitioner, 这样就上抗生素会不
会太aggressive了？
3。bactera感染会有什么后果？
4。脓包本身已经好了，所以吃药以后管没管用到时我也不知道啊，到时要不要再约个
医生检查一下？

i think this dedicated bacteria is kind of highly selective pathogen. for

but when i talked to my classmate--who is an american, she said, oh, i think
it should be a pathogen that could work on the host all the time, not only in
a special circumstance.
so then that's why i ask here.
