Infection transmission

In addition to the role of chemokines/chemokine receptors in viral infection, transmission, and pathogenesis, chemokines also play important roles in cellular trafficking and survival pathways. The role of chemokines and their receptors are of particular importance in the development of neurologic complications of AIDS, involving mechanisms discussed in the following sections. 

Populations persons especially prone to contract the condition with accidental (poisons) or natural (infections) transmission. All means that all population groups are vulnerable. 

Children are most hkely to experience illness with Y. enterocolitica infection. Transmission of infection occurs frequently by ingestion of contaminated food or water. The organisms have been isolated from a variety of food sources, including pigs and raw goat and cow milk. Refrigeration does not deter the development of adherence and invasive virulence factors. 

Generally speaking, infection transmission occurs via three routes contact, air and water. Advances in molecular detection methods and sampling techniques for viruses, bacteria and fungi have enabled researchers to identify the exact strain and source of infections, and thereby develop a better understanding of transmission (Ulrich etal, 2008). Contact is widely considered the most frequent transmission route, but in practice all three routes may interact in the spread of nosocomial infections. Waterborne transmission is a serious problem in some circumstances, but there are few studies on prevention and we will not consider it further here.

Inactivation and Removal of Viruses. In developing methods of plasma fractionation, the possibiHty of transmitting infection from human vimses present in the starting plasma pool has been recognized (4,5). Consequentiy, studies of product stabiHty encompass investigation of heat treatment of products in both solution (100) and dried (101) states to estabHsh vimcidal procedures that could be appHed to the final product. Salts of fatty acid anions, such as sodium caprylate [1984-06-17, and the acetyl derivative of the amino acid tryptophan, sodium acetyl-tryptophanate [87-32-17, are capable of stabilizing albumin solutions to 60°C for 10 hours (100) this procedure prevents the transmission of viral hepatitis (102,103). The degree of protein stabilization obtained (104) and the safety of the product in clinical practice have been confirmed (105,106). The procedure has also been shown to inactivate the human immunodeficiency vims (HIV) (107). 

Vimses are obligate intracellular parasites. They only exhibit activity by infecting other living organisms, thus they are not a practical concern in industrial microbiological fields. The exception is where viral contamination of the product or process represents a threat of transmission of disease. Microscopic insects and protozoans are also not addressed in this article (see Insectcontroltechnology). 

Hepatitis is acute or chronic inflammation of the liver, which is frequently caused by infection with hepato-tropic viruses. Several forms of viral hepatitis (A, B, C, D, E) are known, which result from infection with viruses belonging to separate virus families, differing in their genomic organization, replication strategies, morphology and modes of transmission. 

HSV2 (herpes simplex virus 2), which causes significant morbidity and is an important cofactor for the transmission of HIV infection was recently targeted in a mouse model by local application of siRNA mixed with lipids. The results suggested that siRNA could work as active components of microbicides to prevent viral infection or transmission [2].
