i apologise u were abs right. here is the explanation Explanation: A leukocytosis is an increase in the number of circulating leukocytes. A neutrophilic leukocytosis (neutrophilia) typically occurs in response to some sort of infection. All of the other conditions listed are associated with eosiniophilia. Typically, acute bacterial infections are not associated with an eosinophilia.The most common causes of eosinophilia are allergic diseases and parasitic infections. The parasitic infections which are associated with eosinophilia involve invasion of the tissues. In addition, there are several other causes of eosinophilia. The mnemonic for eosinophilia is 'worms, wheezes, and weird diseases'. Hayfever and asthma both are due to a type I immune injury (IgE mediated), in which eosinophilia occurs. Ascaris is a parasitic tissue infection (non respiratory). 'Weird diseases' refers to wide array of other conditions, including Hodgkin's disease, eosinophilic gastroenteritis, Loffler's syndrome and others (this is not an exhaustive list).

It must be C, check emedicine: http://www.emedicine.com/ped/topic1303.htm
Neutrophilia: Neutrophilia (ie, neutrophil count exceeding the reference range for age) may be due to the following conditions. o Infection (most common cause): Most bacterial infections cause neutrophilia with bandemia (increased number of bands beyond the reference range). Some bacterial infections do not cause neutrophilia. For example, typhoid fever causes leukopenia and/or neutropenia. Infants and preterm infants in particular have small storage pools of neutrophils in the bone marrow. Therefore, neutropenia develops in severe or chronic infections because the neutrophilic demand is greater than the supply. |
