Diarrheic fecal samples from 258 pre-weaned calves (1-30 day-old) from 9 dairy farms located in Banat region, Romania, were microscopically examined for the presence of Cryptosporidium oocysts. Overall, 65 (25%) samples were found positive.

The past decades have witnessed enormous technological improvements towards the development of simple, cost-effective and accurate rapid diagnostic tests for detection and identification of infectious pathogens. Among them is dengue virus, the etiologic agent of the mosquito-borne dengue disease, one of the most important emerging infectious pathologies of nowadays.

Multidrug resistance (MDR) to antibiotics presents a serious therapeutic problem in the treatment of bacterial infections. The importance of this mechanism of resistance in clinical settings is reflected in the increasing number of reports of multidrug resistant isolates. In Salmonella enterica, the most common etiological agent of food borne salmonellosis worldwide, MDR is becoming a major concern.

Globally, leptospirosis poses an increasing public health problem, as evidenced by markedly increasing incidence rates and multiple outbreaks in all continents. Yet, the disease is severely neglected and hence, its global burden is largely unknown.

BACKGROUND:
Active efflux systems and reduced cell-wall permeability are considered to be the main causes of mycobacterial intrinsic resistance to many antimicrobials. In this study, we have compared the Mycobacterium smegmatis wild-type strain mc2155 with knockout mutants for porins MspA (the main porin of M. smegmatis) and MspC, the efflux pump LfrA (the main efflux pump system of M. smegmatis) and its repressor LfrR for their ability to transport ethidium bromide (EtBr) on a real-time basis.

Background: Unlike in HIV-1 infection, the majority of HIV-2 patients produce broadly reactive neutralizing antibodies, control viral replication and survive as elite controllers.

Canine leishmaniosis (CanL) caused by the protozoan parasite Leishmania infantum is a chronic systemic disease that is endemic in certain parts of the world. The domestic dog is the most important reservoir of L. infantum and is the main source of infection for other animals and for the human population.

Mycobacteria are responsible for some of the oldest diseases known to man, usually associated with high morbility and mortality rates. An example is tuberculosis (TB), a major public health problem that accounts for eight million new cases each year.
