Buffalopox is a contagious viral disease affecting milch buffaloes (Bubalus Bubalis) and, rarely, cows. The disease has zoonotic implications, as outbreaks are frequently associated with human infections, particularly in the milkers. Buffalopox is associated with high morbidity (80%). The clinical symptoms of the disease are characterized by wartline lesions on the udder, teats, inguinal region, base of the ears, and over the parotid. In the severe form, generalized rash is observed. Although the disease does not lead to high mortality, it has an adverse effect on the productivity and working capacity of the animals resulting in large economic losses. The outbreaks of buffalopox occurred frequently in India, Pakistan, Bangladesh, Nepal, Iran, Egypt, and Indonesia, where buffaloes are reared as milch animals. The buffalopox is closely related with other Orthopoxviruses. In particular, it is close to the vaccinia virus. There is a view that the buffalopox virus might be derived from the vaccinia virus. It is possible that it became pathogenic to humans and animals through adaptive evolution of the genome by obtaining the virulence genes. PCR is performed for the C18L gene for the purpose of specific detection and differentiation of the buffalopox virus from other orthopoxviruses. The C18L gene encodes the ankyrin repeat protein, which determines the virus host range. The open reading frame of this gene is only 150-nucleotide long as against 453 nucleotide in the vaccinia virus, 756 - in the camelpox virus, and 759 - in the cowpox virus. It can be concluded that a systematic study based on the epidemiology of the virus, existence of reservoirs, biological transmission, and the molecular organization of the buffalopox virus from buffalo, cow, and humans may pave the way to a better understanding of the circulating virus and contribute to the control of the disease using the suitable diagnostic and prophylactic measures.

Bluetongue is non contagious vector borne viral disease of small ruminants. It transmits by biting of culicoids midges and causes severe economic losses to animal owner in term of high morbidity, decreased production and impaired reproduction. Balochistan, being largest province of the country have scattered population in far remote areas. About 70% of the provincial population rely upon livestock rearing for their livelihood. Kalat is largest division of the province that stretches from Kalat city upto Lasbella including Khuzdar, Kharan and Awaran. It is located on main RCD route that will ultimately boost the animal marketing and their easy access to main market. Although different vaccines are practiced throughout the province but no such vaccine is available against BTV in the country. That’s why animals are facing problems of some undiagnosed diseases. This review provides necessary information about disease in the region. It is need of the time to educate farmer and strict vigilance may be practiced for proper and timely vaccination of all animals to curtail deadliest diseases in the region.

ABSTRACT During vaccinia virus replication, mature virions (MVs) are wrapped with cellular membranes, transported to the periphery, and exported as extracellular virions (EVs) that mediate spread. The A26 protein is unusual in that it is present in MVs but not EVs. This distribution led to a proposal that A26 negatively regulates wrapping. A26 also has roles in the attachment of MVs to the cell surface and incorporation of MVs into proteinaceous A-type inclusions in some orthopoxvirus species. However, A26 lacks a transmembrane domain, and nothing is known regarding how it associates with the MV, regulates incorporation of the MV into inclusions, and possibly prevents EV formation. Here, we provide evidence that A26 forms a disulfide-bonded complex with A27 that is anchored to the MV through a noncovalent interaction with the A17 transmembrane protein. In the absence of A27, A26 was unstable, and only small amounts were detected. The interaction of A26 with A27 depended on a C-terminal segment of A26 with 45% amino acid identity to A27. Deletion of A26 failed to enhance EV formation by vaccinia virus, as had been predicted. Nevertheless, the interaction of A26 and A27 may have functional significance, since each is thought to mediate binding to cells through interaction with laminin and heparan sulfate, respectively. We also found that A26 formed a noncovalent complex with A25, a truncated form of the cowpox virus A-type inclusion matrix protein. The latter association suggests a mechanism for incorporation of virions into A-type inclusions in other orthopoxvirus strains.

H9N2 avian influenza outbreaks have caused great economic losses to the poultry industry in recent decades due to a decrease of egg production, high morbidity, and mortality. Due to different antigenic variants, Influenza virus has become problematical because it has the ability to cross the species barrier. As it is highly pathogenic so its diagnosis and vaccines are of high importance. Hemagglutination inhibition (HI) test is mostly used for subtyping and detection of antibody titer against the virus. Furthermore, its continuous mutations in the HA gene transforms AIV subtype H9N2 (a low pathogenic subtype) into high pathogenic virus subtypes like H5N2 and H7N7 that may have pandemic potential. Thus, it is necessary to identify various antigenic variants of Influenza virus, so it is direly needed to study the HA gene, its attachment to host receptors, the release of genetic material and pathogenicity. In the present study, virus samples from poultry were isolated. Both serological and molecular confirmation was done for 100 samples collected from the different area. They were properly labeled and prepared for the process of egg inoculation in embryonated eggs. The virus was grown in amnioallantoic membrane of embryonated eggs and harvested fluid is then proceeded for confirmatory testing. Hemagglutination and Hemagglutination inhibition testing was done. RNA was extracted by the kit method and cDNA was synthesized. Reverse transcriptase (RTPCR) was performed using specific primer sets and then the PCR product was run on agarose gel. The bands obtained were sent for sequencing.

Purpose Cerebral venous sinus thrombosis (CVST) is an unusual and potentially life-threatening condition with variable and nonspecific clinical symptoms and high morbimortality rates. Standard therapy consists of systemic anticoagulation; although there is no clear evidence about the best choice for treatment, intravenous heparin is used as the first-line treatment modality. Intravenous sinus thrombolysis can be an effective and relatively safe treatment for acutely deteriorating patients who have not responded to conventional therapy. This case report presents the possibility of endovascular treatment in multiple steps with mechanical thrombolysis with balloon, local pharmacological thrombolysis and stenting, in a patient with a severe form of CVST. Case summary A 67-year-old woman presented severe headache, agitation and confusion with diagnosis of venous sinus dural thrombosis in both lateral sinus and torcula. After 24 h there was neurological worsening evolving with seizures and numbness even after starting heparin, without sinus recanalization; CT scan showed left temporal intracerebral hemorrhage. We decided to take an endovascular approach in multiple steps. The first step was mechanical static thrombolysis with balloon; the second step was dynamic mechanical thrombolysis with a balloon partially deflated and “pulled”; the third step was local thrombolysis with Actilyse™; finally, the fourth step was angioplasty and reconstruction of the sinuses using multiple carotid stents and complete angiographic recanalization of both sinuses and torcula. After 24 h of endovascular treatment there was full clinical recovery and no tomographic complications. Conclusion This result shows that mechanical clot disruption, intrasinus thrombolysis and reconstruction of wall sinuses with stenting can be an endovascular option in the severe form of CVST with intracerebral hemorrhage and rapid worsening of neurological symptoms. Although this type of treatment can re-channel the occluded sinuses, further comparative and randomized studies are needed to clarify its efficacy versus other therapeutic modalities.

Background: Contagious caprine pleuropneumonia (CCPP), caused by Mycoplasma capricolum subsp. Capripneumoniae (Mccp), is one of the most important goat diseases causing high morbidity and mortality, these results in heavy economic losses to countries like Somalia, which is a country affected the civil war of the 1990s. Objective: Generally, the disease presence has been reported in the country. However, there is no quantitative data on the prevalence and distribution of the disease has been scientifically reported in the country. Methods: A cross-sectional study was conducted from September 2019 to June 2020 in three villages of Afgoye district of Somalia to assess the seroprevalence and identify the associated risk factors for the occurrence of the CCPP. The risk factors considered included sex, age, and locations. Results: A total of 100 blood samples were collected and evaluated by Capri-Latex Agglutination Test (Capri-LAT). A total of 49/100 (49%, CI 95%: (38.86%-59.2%) goats were seropositive for anti-CCPP antibody. The epidemiological risk factors considered, sex, age and locations, were not significantly associated with the CCPP sero prevalence (p>0.05). However, the sero positivity was slightly higher in female (51%, 95% CI: 39.8-62.6), >3 years old goats (86.3%, 95% CI: 48.9-87.4) and Markazka village (56%, 95% CI: 41.3-70.0) compared to male (40%, 95% CI: 19.1-63.9), 1-3 years old (57.5%, 95% CI: 40.9- 73.0), and Shareeco (43.8%, 95% CI: 19.8-70.1) and Siinka (41.2%, 95% CI: 24.7-59.3) villages, respectively. Conclusion: The present study indicates the prevalence of CCPP in the studies areas and this requires practicable measures to be put in place towards the control of the disease.

Infectious Bursal Disease (IBD), also called Gumboro, was disease which attacked cells in the bursa of fabricius, causing interference with the chicken's immune system or immunosuppressive. IBD was the one of viral disease that often attacks chickens in the field. The aim of this study was to determine the diagnosis of IBD by through at clinical symptoms and necropsy that can still be relevant on in the field. The diagnosis of IBD correctly, cheaply, easily and quickly in the field is very important to optimize the health care management and evaluation program. The method used was by observing clinical symptoms of broiler chickens in commercial farms suspected of contracting IBD and observing post-death organs (necropsy). The object of necropsy was 5 samples of broiler chickens from the farm. Data was analyzed descriptively. The results of this study was the broiler chickens that infected with IBD could be diagnosed through clinical symptoms and post-death organ changes, so that the diagnosis for IBD cases in the field used the observation of clinical symptoms and necropsy are still relevant.

Porcine epidemic diarrhoea (PED) is a highly contagious enteric viral disease of pigs with a high morbidity and mortality rate, which ultimately results in huge economic losses in the pig production sector. The etiological agent of this disease is the porcine epidemic diarrhoea virus (PEDV) which is an enveloped, positive single-stranded RNA virus. The aim of this study was to perform molecular characterization of PEDV to identify the strains circulating in Poland. In this study, 662 faecal samples from 2015 to 2021 were tested with reverse transcription quantitative real-time PCR (RT-qPCR) and the results showed that 3.8% of the tested samples revealed a positive result for PEDV. A phylogenetic analysis of the complete genome and complete S gene sequences showed that Polish PEDV strains belonged to the G1b (S-INDEL) subgroup and were closely related to the European PEDV strains isolated from 2014 to 2019. Furthermore, RDP4 analysis revealed that the Polish PEDV strains harboured a recombinant fragment of ~400 nt in the 5’ end of S gene with PEDV and swine enteric coronavirus (SeCoV) being the major and minor parents, respectively. Antigenic analysis showed that the aa sequences of neutralizing epitopes were conserved among the Polish PEDV strains. Only one strain, #0100/5P, had a unique substitution in the COE epitope. However, Polish PEDV strains showed several substitutions, especially in the COE antigen, as compared to the classical strain CV777. To the best of our knowledge, this is the first report concerning the molecular characterization of porcine epidemic diarrhoea virus strains, as well as the first phylogenetic analysis for PEDV in Poland.

Reports regarding brain inflammation, known as encephalitis, have shown an increasing frequency during the past years. Encephalitis is a relevant concern to public health due to its high morbidity and mortality. Infectious or autoimmune diseases are the most common cause of encephalitis. The clinical symptoms of this pathology can vary depending on the brain zone affected, with mild ones such as fever, headache, confusion, and stiff neck, or severe ones, such as seizures, weakness, hallucinations, and coma, among others. Encephalitis can affect individuals of all ages, but it is frequently observed in pediatric and elderly populations, and the most common causes are viral infections. Several viral agents have been described to induce encephalitis, such as arboviruses, rhabdoviruses, enteroviruses, herpesviruses, retroviruses, orthomyxoviruses, orthopneumovirus, and coronaviruses, among others. Once a neurotropic virus reaches the brain parenchyma, the resident cells such as neurons, astrocytes, and microglia, can be infected, promoting the secretion of pro-inflammatory molecules and the subsequent immune cell infiltration that leads to brain damage. After resolving the viral infection, the local immune response can remain active, contributing to long-term neuropsychiatric disorders, neurocognitive impairment, and degenerative diseases. In this article, we will discuss how viruses can reach the brain, the impact of viral encephalitis on brain function, and we will focus especially on the neurocognitive sequelae reported even after viral clearance.
