Rapid and accurate diagnosis of infectious agents is essential for patient care, disease control, and countermeasure development. The present serologic diagnosis of Zika virus (ZIKV) infection relies mainly on IgM-capture ELISA which is confounded with the flaw of cross-reactivity among different flaviviruses. In this communication, we report a multiplex microsphere immunoassay (MIA) that captures the diagnostic power of viral envelope protein (that elicits robust, yet cross-reactive antibodies to other flaviviruses) and the differential power of viral nonstructural proteins NS1 and NS5 (that induce more virus-type specific antibodies)...

Serological diagnosis of Zika virus (ZIKV) infections is challenging due to high cross-reactivity between flaviviruses. We evaluated the diagnostic performance of a novel anti-ZIKV ELISA based on recombinant ZIKV non-structural protein 1 (NS1). Assay sensitivity was examined using sera from 27 patients with reverse transcription (RT)-PCR-confirmed and 85 with suspected ZIKV infection. Specificity was analysed using sera from 1,015 healthy individuals. Samples from 252 patients with dengue virus (n = 93), West Nile virus (n = 34), Japanese encephalitis virus (n = 25), chikungunya virus (n = 19) or Plasmodium spp...

Zika virus (ZKV) infection is a huge public health problem in Brazil because of the increased incidence of microcephaly in neonates from infected mothers. Detection of specific IgG antibodies in maternal serum samples constitutes an important approach for diagnosing ZKV infection and evaluating its relationship with neonatal microcephaly. However, as there is no serological test produced in Brazil to detect IgM and IgG antibodies against ZKV, we sought to examine specific IgG in serum samples from patients or suspected mothers to detect previous infection and to test for specificity with regard to flaviviral infections occurring in the same area...

BACKGROUND:  Usually, immunoglobulin M (IgM) serologic analysis is not sufficiently specific to confirm Zika virus (ZIKV) infection. However, since IgM does not cross the placenta, it may be a good marker of infection in neonates. METHODS:  We tested blood from 42 mothers and neonates with microcephaly and collected cerebrospinal fluid (CSF) specimens from 30 neonates. Molecular assays were performed for detection of ZIKV, dengue virus, and chikungunya virus; IgM enzyme-linked immunosorbent assays and plaque-reduction neutralization tests (PRNTs) were performed to detect ZIKV and dengue virus...

BACKGROUND: Secondary dengue causes more severe disease than the primary. Early on, it is important to differentiate the two. We tried to find important clinical and laboratory differences between the two for the purpose of early differentiation. METHODS: One hundred fourteen patients confirmed on reverse transcriptase-polymerase chain reaction (RT PCR) were studied. On day 2 of illness IgM and IgG indices were studied for calculation of IgG/IgM ratio. A one-step immunochromatographic assay was used for classification of patients into primary and secondary dengue...

ZIKV has emerged as grave global health issue in the past few years. ZIKV was firstly isolated in 1947 from a rhesus sentinel monkey in the Zika forest in Uganda. It is usually transmitted by the bite of infected mosquitoes and infects skin fibroblasts, skin keratinocytes etc. ZIKV until now was under reported because of its clinical similarity with the dengue and chikungunya. It usually spread through the course of the sylvatic cycle. In this cycle, the virus or pathogen lifespan is spent between the wild animal and vectors...

INTRODUCTION: Brazilian spotted fever is an infectious disease with a high mortality rate if not treated early. Differential diagnosis is difficult, as the first clinical signs are non-specific and can be confused with other diseases. The aim of the study was to investigate evidence of infection with Rickettsia rickettsii and Rickettsia parkeri in negative sera samples, collected in 2014, from patients with suspected leptospirosis, dengue fever, and meningococcal disease in Atibaia and Bragança Paulista municipalities of the State of São Paulo...

Dengue infection accompanied by unusual complications and manifestations has been described before. Here we report a case of dengue encephalitis who was IgM positive for dengue serology and had presented to us with only motor weakness after an acute febrile episode. Dengue presenting as encephalitis is in itself a very rare feature and that too, pure motor weakness has hardly ever been reported before.

BACKGROUND: Arboviruses are important emerging viruses worldwide. The signs and symptoms of Zika virus (ZIKV) infection are similar to those presented by infections with dengue virus (DENV) and chikungunya virus (CHIKV). Furthermore, diagnosis of ZIKV infection is particularly challenging in dengue endemic regions and with co-circulation of DENV, CHIKV, and ZIKV, making diagnosis based solely on clinical and epidemiological data unreliable. As these three viral infections share similar clinical manifestations, differential diagnosis is crucial...

INTRODUCTION: Dengue fever is a major public health problem worldwide. The 2011 revised World Health Organization (WHO) guidelines have emphasized on early diagnosis and intervention to reduce the case fatality rate due to dengue fever. Rapid diagnostic tests like NS1 antigen assays have improved the detection of cases in early clinical phase of illness but its role as a predictor of severe dengue infection is not very clear. AIM: To evaluate the utility of NS1 Ag assay as an early diagnostic marker and predictor of severe dengue infection...
