BACKGROUND & OBJECTIVE The present study was conducted on the prevalence of malaria as co-infection amongst 'asymptomatic HIV' and 'symptomatic HIV' subjects to see if such prevalence deviated from that commonly reported in apparently health individuals in same locality. METHODS A prospective study that involved 196 participants grouped according to their HIV status as: 'asymptomatic HIV sero...

BACKGROUND HIV, HBV, Syphilis and HCV share common modes of transmission. OBJECTIVE The study was aimed to determine the co-infection rate of HIV, HBV and Syphilis among HCV seropositive identified blood donors. METHODS The study was conducted on blood samples screened as HCV seropositive at Nepal Red Cross Society, Central Blood Transfusion Service, Kathmandu, Nepal. HCV seropositive sampl...

Neuromyelitis optica (NMO) is a rare autoimmune disease affecting the optic nerves and spinal cord. In the majority of NMO patients anti-aquaporin-4 antibodies (AQP4-IgG) are detected. Here we assessed a nationwide incidence of AQP4-IgG-seropositive NMO spectrum disorders (NMOSD) in the Netherlands based on results of one central laboratory. Data were collected since the introduction of the hig...

Two sibling foxhounds born to a Leishmania seropositive bitch were presented after testing seropositive for Leishmania. Leishmania infantum infection was detected via histopathology, culture, and quantitative polymerase chain reaction (q-PCR). This is the first report of natural infection with Leishmania infantum with the possibility for vertical transmission in North America.

The aim of this study was to evaluate the seroprevalence of human herpesvirus 8 (HHV-8) in a group of 150 patients awaiting heart transplants and to detect HHV-8 seroconversion after transplantation. Four patients were HHV-8 seropositive before transplantation, and one of them developed Kaposi's sarcoma. One patient converted to seropositive HHV-8 status after transplantation.

Caprine arthritis-encephalitis is an economically important disease of goats. It is evident that horizontal transmission through respiratory secretions and milk plays an important part in the disease spread whereas the role of sexual transmission remains questionable. The cross-sectional study was carried out to investigate the relationship between presence of small ruminant lentivirus (SRL V)-...

Oestrus ovis (Diptera: Oestridae) causes an important cosmopolitan parasitosis of the nasal and sinusal cavities of sheep and goats called oestrosis. Our objective was to analyze the participation of erythrocytes in the antioxidant system in goats seropositive to O. ovis infection under field conditions. Fifty female goats naturally exposed to O. ovis infection from Baja California Sur, México,...

Acquisition and loss rates and estimates of duration of oral and vaginal Candida species colonization and candidiasis were examined among 868 human immunodeficiency virus (HIV)-seropositive and 437 at-risk HIV-seronegative women monitored prospectively during 1993-1999. Colonization and candidiasis acquisition rates, both oral and vaginal, were significantly higher among HIV-seropositive women;...

Major implications on a country's economy, food source, and public health. With recent concern over the highly pathogenic avian influenza outbreaks around the world, government agencies are carefully monitoring and inspecting live bird markets, commercial flocks, and migratory bird populations. However, there remains limited surveillance of non-commercial poultry. Therefore, a cross-sectional s...

BACKGROUND Brucellosis and coxiellosis are known to be endemic in ruminant populations throughout Afghanistan, but information about their prevalence and factors that affect prevalence in householders and livestock under diverse husbandry systems and pastoral settings is sparse. METHODS/PRINCIPAL FINDINGS We conducted a cross-sectional survey to investigate the seroprevalence of brucellosis a...
