The aims of the current study are to describe a case of POGS with uveitis due to flea-borne typhus (FBT) and to present a diagnostic and therapeutic approach to POGS. The patient, a 38-year old man, presented with persistent unilateral eye pain, fever, rash, preauricular and submandibular lymphadenopathy, and laboratory findings of FBT: hyponatremia, elevated transaminase and lactate dehydrogenase levels, thrombocytopenia, and hypoalbuminemia. His condition rapidly improved after starting doxycycline. Soon after hospitalization, he was diagnosed with uveitis, which responded to topical prednisolone. To derive a diagnostic and empiric therapeutic approach to POGS, we reviewed the cases of POGS from its various causes since 1976 to discern epidemiologic clues and determine successful diagnostic techniques and therapies; we found multiple cases due to cat scratch disease (CSD; due to Bartonella henselae) (twelve), tularemia (ten), sporotrichosis (three), Rickettsia conorii (three), R. -

Crimean-Congo Hemorrhagic Fever
Crimean-Congo Importance Crimean-Congo hemorrhagic fever (CCHF) is caused by a zoonotic virus that Hemorrhagic seems to be carried asymptomatically in animals but can be a serious threat to humans. This disease typically begins as a nonspecific flu-like illness, but some cases Fever progress to a severe, life-threatening hemorrhagic syndrome. Intensive supportive care is required in serious cases, and the value of antiviral agents such as ribavirin is Congo Fever, still unclear. Crimean-Congo hemorrhagic fever virus (CCHFV) is widely distributed Central Asian Hemorrhagic Fever, in the Eastern Hemisphere. However, it can circulate for years without being Uzbekistan hemorrhagic fever recognized, as subclinical infections and mild cases seem to be relatively common, and sporadic severe cases can be misdiagnosed as hemorrhagic illnesses caused by Hungribta (blood taking), other organisms. In recent years, the presence of CCHFV has been recognized in a Khunymuny (nose bleeding), number of countries for the first time. Karakhalak (black death) Etiology Crimean-Congo hemorrhagic fever is caused by Crimean-Congo hemorrhagic Last Updated: March 2019 fever virus (CCHFV), a member of the genus Orthonairovirus in the family Nairoviridae and order Bunyavirales. CCHFV belongs to the CCHF serogroup, which also includes viruses such as Tofla virus and Hazara virus. Six or seven major genetic clades of CCHFV have been recognized. Some strains, such as the AP92 strain in Greece and related viruses in Turkey, might be less virulent than others. Species Affected CCHFV has been isolated from domesticated and wild mammals including cattle, sheep, goats, water buffalo, hares (e.g., the European hare, Lepus europaeus), African hedgehogs (Erinaceus albiventris) and multimammate mice (Mastomys spp.). -

A 33-year-old Caucasian woman presented to the emergency department with a 6-day his- tory of fever (103°-104°F) and right groin pain and swelling. Associated symptoms included headache, diarrhea, malaise, weakness, nausea, cough, and anorexia. Upon presentation, she admitted to a recent hike on a bubonic plague–endemic trail in Colorado. Her vital signs were unremarkable, and the physical examination demonstrated normal findings except for tender, erythematous, nonfluctuant right inguinal lymphadenopathy. The patient was admitted for intractable pain and fever and started on intravenous cefoxitin 2 g IV every 8 hours and oral doxycycline 100 mg every 12 hours for pelvic inflammatory disease vs tick- or flea-borne illness. Due to the patient’s recent trip to a plague-infested area, our suspicion for Yersinia pestis infection was high. The patient’s work-up included a nega- tive pregnancy test and urinalysis.

Protecting Yourself from Zoonotic Infection
PROTECTING YOURSELF FROM ZOONOTIC INFECTION What is a Zoonoses? A zoonotic disease is an infection that is naturally transmitted from vertebrate animals to human beings. Many of these infections are transmitted directly but others are passed via vectors such as mosquitoes or fleas. Not all animal diseases are zoonotic and far more human illnesses result from contact with other humans than from animals. However, it is important for anyone working with animals to be aware of the potential for infection and takes steps to prevent exposure. The following lists some of the more common or severe zoonoses and ways to help protect yourself and others from exposure. IMPORTANT RULES TO HELP YOU AVOID DEVELOPING A SERIOUS ZOONOTIC ILLNESS: Stay current on appropriate vaccinations, such as tetanus and rabies. Wash your hands frequently with antibacterial soap, especially after handling any animal and prior to eating or smoking. Wear long pants and sturdy shoes or boots. Use gloves when handling animals and when cleaning up feces, urine, or vomit. Immediately disinfect scratches and bite wounds thoroughly. Keep scratches or other abrasions covered, especially when cleaning up after animals. Learn safe and humane animal-handling techniques and use proper equipment. Seek assistance when handling animals whose dispositions are questionable. If exposed to tick-infested areas, check your body and clothing frequently. Use tweezers and wear gloves to remove ticks, taking care not to squeeze or puncture the body of the tick. Report any bites or injuries to a supervisor and seek medical treatment as appropriate. Tell your physician that you work closely with animals, and visit him or her regularly. -

The infestation can reach high levels, seemingly very quickly. However, the early The brown dog tick, Rhipicephalus sanguineus Latreille, has stages of the infestation, when only a few individuals are been found around the world. Many tick species can be present, are often missed completely. The first indication carried indoors on animals, but most cannot complete their the dog owner has that there is a problem is when they start entire life cycle indoors. The brown dog tick is unusual noticing ticks crawling up the walls or on curtains. among ticks, in that it can complete its entire life cycle both indoors and outdoors. Because of this, brown dog tick infestations can develop in dog kennels and residences, as well as establish populations in colder climates (Dantas- Torres 2008). Although brown dog ticks will feed on a wide variety of mammals, dogs are the preferred host in the United States and appear to be a necessary condition for maintaining a large tick populations (Dantas-Torres 2008). Brown dog tick management is important as they are a vector of several pathogens that cause canine and human diseases. Brown dog tick populations can be managed with habitat modification and pesticide applications. The taxonomy of the brown dog tick is currently under review Figure 1.

Interestingly, cases of Rocky Mountain spotted fever in Nebraska have increased on a year over year basis, yet the prevalence of D. variabilis vectoring R. rickettsii has not been established for Nebraska. Here we sought to set a baseline for the prevalence of D. variabilis vectoring R. rickettsii and other spotted fever group (SFG) rickettsiae. Over a 3 year period, D. variabilis were collected along the Platte River in south central Nebraska. Individual tick DNA was analyzed using endpoint PCR to identify ticks carrying SFG rickettsiae. A total of 927 D. variabilis were analyzed by PCR and 38 (4.1%) ticks tested positive for SFG rickettsiae. Presumptive positives were sequenced to identify the Rickettsia species, of which 29 (76%) were R. montanensis, 5 (13%) were R. amblyommatis, 4 (11%) were R. bellii, and R. rickettsii was not detected. These data indicate that R. rickettsii is likely at a low prevalence in south central Nebraska and spillover of R. amblyommatis into D. variabilis is occurring likely due to the invasive lone star tick (Amblyoma americanum). -
Australian Paralysis Tick (Ixodes Holocyclus)
Australian Paralysis Tick (Ixodes holocyclus) By Dr Janette O’Keefe BscBVMS The Australian paralysis tick (Ixodes holocyclus ) is a very dangerous parasite that affects dogs in Australia; specifically on the east coast from North Queensland to Northern Victoria. The main area of distribution is a narrow area running, (roughly confined to a 20-kilometre band), along the coastal areas as indicated in Figure 1 . In northern parts of Australia, ticks can be found all year around. In the cooler southern areas, tick season is generally from spring through to late autumn (Figure 2) . Fig: 2 – Seasonal distribution of 3 stages of Ixodes holocyclus The Life Cycle of the Paralysis Tick The natural hosts of Ixodes holocyclus include bandicoots, wallabies, kangaroos, and other marsupials – basically immune to the effects of the tick's toxin. Other species affected are human, cattle, sheep, horses, dogs, cats, poultry, and other animals. The Ixodes tick goes through the three stages of Larva (6 legs) , Nymph (8 legs) , and Adult (8 legs) , attaching to and feeding on one host during each stage, then falling off and moulting before re-attaching to the same or more often a different host for the next stage. If no host is available, the adult can survive up to 77 days without feeding. The Female Adult feeds and engorges for 6 (cool weather) to 21 days Fig: 1 – distribution of Ixodes holocyclus (warmer weather), before she drops to the ground to lay eggs, thus beginning the cycle again. It is important to note that the adult female does not inject detectable amounts of toxin until the 3rd day of attachment to the host , with peak amounts being injected on days 5 and 6. -

Throughout Laos, ticks and tick- associated pathogens are poorly known. Fifteen thousand and seventy-three ticks representing larval (60.72%), nymphal (37.86%) and adult (1.42%) life stages were collected. Five genera comprising at least 11 species, including three suspected species that could not be readily determined, were identified from 215 adult specimens: Amblyomma testudinarium Koch (10; 4.65%), Dermacentor auratus Supino (17; 7.91%), D. steini (Schulze) (7; 3.26%), Haemaphysalis colasbelcouri (Santos Dias) (1; 0.47%), H. hystricis Supino (59; 27.44%), H. sp. near aborensis Warburton (91; 42.33%), H.
