This pattern of SlBAK1 expression is consistent with the pattern of infection by tomato-infecting begomoviruses, which infect leaf tissues and move through the phloem but do not invade roots.
Morphological studies of SS1-infected cells showed a more prominent pattern of infection (rounding and clumping) for LnCap, LapC4, PrEC and BPH-1 as compared with Du145 and PC3 cells (Figure 3A).
The early pattern of infection could have been explained if, for genetic or environmental reasons, the infectivity of the virus was high.
The pattern of infection and disease, however, can be changed.
Gastrointestinal infection is ubiquitous worldwide though the pattern of infection varies widely.
A similar pattern of infection formerly occurred with smallpox, a disease that was more frequently fatal but now ostensibly has been eradicated.
Jeronimo, S.M. et al. An emerging peri-urban pattern of infection with Leishmania chagasi, the protozoan causing visceral leishmaniasis in northeast Brazil.
Over the last year, he said, the system has been expanded to detect any pattern of infection that suggests either bioterrorism or a natural outbreak, based on data collected from hospitals, doctors and clinics.
This rather unusual pattern of infection, along with a three- to five-year incubation period (the time that elapses between contact with the bacillus and the onset of symptoms), makes the epidemiology of leprosy particularly difficult to study.
It also highlights the need for examining the dynamics of seasonal or location-specific variation in vector populations to determine the pattern of infection outbreaks.
The distribution pattern of infection in foxes and the relationship of this pattern with landscape and climate was analyzed by geographic information system.
