Introduction

A Better Test for a Potato PestScienceDaily (Aug. 24, 2011) 

This investigation guarantees alimentary security, and promotes food security on the outside

the golden nematode

the pale cyst nematode

Breeders have developed potatoes that can resist the golden nematode

If the pale cyst nematode is found in a field, potatoes cannot be grown there

Part A

A Better Test for a ScienceDaily (Aug. 24, 2011) 

Traditional methods of distinguishing between the two PCN species have relied on time-consuming morphological analyses and PCR

assays.

But Wang and her colleagues

Cloned the parasitism gene

the nematodes use to produce a protein that plays an

important role in the infection process

chorismate mutase.

Part B

New Bacterium Found Causing Tick-Borne Illness Ehrlichiosis in Wisconsin and Minnesota

ScienceDaily (Aug. 31, 2011) 

Part C

Take chorismate mutase genes

Compared the sequences

Identified unique regions in each sequence

Part D

The diagnostic test is one of several new technologies designed to distinguish PCN

types

More sensitive than other systems

It can give reliable results from tiny amounts of nematode material.

Personal comment

It is important for a farmer to know the soil and microorganisms to have a successful development and a good fruit crop, as a student of medicine is important to know the different microorganisms that can cause disease in our patients to choose the appropriate form of treatment

Part A

The new species of Ehrlichia infections can cause febrile illness, found in ticks.

More severe disease may involve multiple organs such

as the lungs, kidneys and brain

Part B

The drug of choice for treating ehrlichiosis

Doxycycline

Prevention

Apply insect repellent and wear pants and long-sleeved shirts when active outdoors

The investigation began after Carol Werner:

Personal comment

It is important to know the diferntes vectors of the disease, because a good knowledge of these allows a good prevention

Medical utility Part A

Medical utility Part B

Medical utility Part C

Intense study of these two types of bacteria will facilitate the management and prevention of these.
